  The forums are down because someone has used a script to take
  advantage of a bug in the vbulletin php code. They did it from the
  con, and we are aware of who did it. We would prefer them to contact
  us so we can deal with it rather than Federal Agents. Thanks, Simon

  3. Robert Steele - Why Hackers Should be Considered a National Asset  (5.5M MP3)  (M4B)
    • President of Open Source Solutions, Inc.  A former spy, experienced bureaucrat, radical visionary.  Tofflers call him the "rival store" to CIA.  Robert will explain why hackers should be considered a national asset.
    • Robert David Steele is the bureaucrat's worst nightmare: a highly educated and skilled bureaucrat himself, now a successful businessman, who has seen the light and been quoted around the world--including the notorious Singapore Straits Times saying "hackers are a national resource."  He means it, and people are starting to listen.
    • Steele spent 18 years as a Central Intelligence Agency spy and Marine Corps intelligence officer.  He has done three overseas tours recruiting traitors, participated in signal collection operations, helped program funds of overhead imagery satellites, and been the senior civilian responsible for establishing the new $20 million Marine Corps Intelligence Center.
    • He holds graduate degrees in international relations (predicting revolution) and public administration (strategic and tactical information management for national security), is a distinguished graduate of the Naval War College, completed the Harvard Executive Program (Intelligence Policy), and spent two years at CIA expense learning about artificial intelligence.
    • Steele was introduced to cyberspace by Howard Rheingold and John Perry Barlow, and he's never been the same.  His article in the Whole Earth Review, "E3i: Ethics, Ecology, Evolution, and Intelligence" established for the first time the concept of a citizens intelligence agency (cia) and an "open books" approach to national intelligence.
    • Do *not* make the mistake of thinking Steele is anti-establishment--on the contrary, he *is* the establishment--of the future--and his contemporaries in the halls of power are just starting to figure that out.  Where Steele makes a different, is in understanding that the communications and computing industries have been criminally negligent (or maybe just stupid), the government has been out to lunch, and hackers have something important to say about making cyberspace a safe place to work and play.

  4. Jim Settle - Ex-FBI Computer Crime Investigator  (6.5M MP3)  (M4B)

    • Curtis E.A. Karnow is the coordinator of the Communications and Technology Group at the San Francisco law firm of Landels, Ripley & Diamond.  A former federal prosecutor and currently judge pro tem for various courts in the San Francisco area, Mr. Karnow specializes in intellectual property litigation, high-tech and computer law.  His clients include a worldwide telecommunications company, software developers including Phil Zimmermann (PGP), distributors and users, and global home video game and multimedia manufacturers and publishers.  He is the author of numerous papers in the fields of computer law and virtual reality, litigation, and arbitration, and serves on the board of Leonardo, the Journal of Arts, Technology and Sciences published by MIT.

    • If you have an interest in how to design an attack, from beginning to end, you don't want to miss this remarkable theoretical discussion concerning the hypothetical "XYZ Insurance Company" and their data.

  7. Theora - Survey of IRC Girrrlz, Including Vamprella, "Don't You Hate it When That Happens?"  (2.7M MP3)  (M4B)
    • I was going to talk about all the really bad things that have happened to me and a lot of other people in the past year.  You know, like having your shoe stolen while you're eating at Taco Bell.  That happened to me.  Or your house catching fire.  Or getting stuck in a dumpster.  Or having your head shaved when you are asleep.  Or having someone impersonate you on IRC and then finding out that your friends actually think the impersonator is nicer and cooler than you.  I was going to write about stuff like having your uninsured new laptop computer stolen, like.. yes this really happened to me before someone stole my shoe and my NIN CD.  But then I thought, hey, why not talk about something happier.  So I asked all the people I could find 'what is happy' and they said "LOVE."  Well, some of them said some variations of it, but generally it involved male and female interaction.
    • So, thinks me, this is a perfect thing to talk about.  I already studied and released a linguistics study on how males and females talk differently on IRC in hacking channels.  (Females are more technically inclined, vocabulary wise).  But that wasn't really about 'love.'  So, I decided to just ask people 'What are you like.. if some guy wants to find a girl that he could actually really 'love,' what kind of girls would you say are in this scene.'
    • My little talk is entitled females of #hack -- not 'female hackers' and not 'females in search of hackers,' but females of #hack.  A more appropriate title would be "what are women who are into the hacking scene and who hang out on IRC and who don't have anything better to do than answer these dumb questions really like like?" but this little talk is as it is.  females of #hack.  All lower case.  The reason I'm going to be talking about this is because lot of guys ask me where they can meet girls.  Girls who know about computers.  Girls who know what hacking is about.  Girls who understand those late nights at the lab.  So come see what the IRC hacker femmes have to say, complete with slides.  Ok, so I drew them with crayons.  But so what.  If you're nice, I bet they will send you GIFS.

  12. Glenn Campbell - Overview of Governmental Activities and Stuff Surrounding Area 51  (7.8M MP3)  (M4B)
    • Glenn Campbell, 35, is the principal local activist seeking greater government accountability at "Area 51," a secret military base 90 miles north of Las Vegas.  Formerly a successful computer programmer from Boston, Campbell moved to the remote town of Rachel, Nevada, in Jan. 1993 to investigate the many strange stories emanating from the base.  His carefully researched book, The Area 51 Viewer's Guide, helped bring mainstream attention to a story that had been dominated by UFO and conspiracy buffs with little concern for facts.
    • Campbell declares himself "seriously interested" in some of the UFO tales emanating from Nevada's military restricted zone, but he dismisses most of the lights-in-the-sky stories reported in Rachel, 25 miles north of the base.  "This place is a circus," says Campbell.  "Anyone can make any claim they want here and get away with it.  Commerce, not truth, seems to be the primary motivation here."  Campbell points out that the area above Rachel is an "intense war games area" where exotic looking lights are produced by conventional military hardware.  Campbell himself says he has never seen a UFO in his 2-1/2 years living in Rachel.
    • Campbell is a bitter enemy of the owners of the Little A'Le'Inn, the well publicized bar, motel and restaurant in Rachel that caters to UFO believers.  They consider him a government agent who has been sent to debunk the UFO sightings here and "muddy the waters" in favor of the military.  Campbell, in turn, considers the owners profiteers who are equally obscuring the truth by endorsing all UFO sightings as real.  Campbell is also not on good terms with Ambassador Merlyn Merlin II from the planet Draconis, a claimed "alien-in-human-form" who is frequent visitor to Rachel.  "The Area 51 story has become a magnet for every nut case on the planet," says Campbell.  "This is a shame, because whatever the truth may be at Area 51, it is being overwhelmed by the noise."
    • Glenn Campbell supports himself through his personal investments and his mail-order business.  He maintain a major presence on the Internet with a free monthly email newsletter (circulation: over 3,000 copies) and a popular World Wide Web page.  Campbell is widely respected for his Area 51 research because he sticks to the facts and a rarely engages in the kind of baseless speculation that dominates the UFO field.  "I am fighting primarily for less secrecy and greater government accountability, which are goals I think everyone can agree with regardless of their view on UFOs," Campbell says.
    • Campbell's email address is  Requests for subscriptions to his newsletter should be directed to  A catalog of publications sold by the Area 51 Research Center is available upon request.  The mailing address is Area 51 Research Center, HCR Box 38, Rachel, NV 89001.

  13. Oscar Meyer - Carefully Consider Your Intentions Before Embarking Down the Road of Serious Hacking  (2.0M MP3 broken)  (M4B)
    • How far are you willing to go?
    • Oscar Meyer?  Well, he's a real wiener.  He is affectionately known to some of his friends as a corn-ball geezer.  He's been more or less successful at hacking most everything that he has comes across for most of his nearly 50 years.  He thinks that hacking might just be a way of life, holds unconventional views, and generally flounders about trying to make things work better.  Although he believes that anything and anyone can be hacked, he is often less successful than he'd like to be.  However, he keeps on trying.
    • Getting past the front door is challenging, interesting and fun.  However, once you are in, what do you do?  Rummaging around, deleting things, screwing things up, or crashing things simply won't do.  This session talks about what to do after you have you've attained access that is not specifically authorized in the context of your broader hacking goals.

    • A fifteen year computer industry veteran, Stephen Cobb is an international consultant and best-selling author who has written more than twenty computer related texts, translated into more than ten languages, with total worldwide sales in excess of one million books.  A frequent contributor to industry publications such as BYTE and Personal Computer World (U.K.), he has written extensively on security related issues and was recently appointed Director of special Projects at the National Computer Security Association (NCSA).  His column on communications is a regular feature in Personal Computer World.  A former tax auditor, petroleum accountant, and IBM classroom instructor, Cobb is an experienced public speaker who has made presentations to numerous industry gatherings, including the Windows Developers Conference, the Virus Bulletin Conference, and Networks Expo Boston.  Now a resident of Florida's Space Coast, he holds a First Class B.A. Honors degree from Leeds University, England.

  11. Netta Gilboa - Sex, Lies and Computer Crimes: The Truth Behind the Indictment of "Computer Genius" Christopher Schanot
    • On March 25, 1996 Christopher Schanot was arrested based on an 11 day old warrant which stemmed from an indictment in Missouri for five counts of computer and access fraud involving Bellcore, SRI, Sprint and Southwestern Bell.  Although he was not indicted for crimes involving the Internet Libertaion Front, the FBI lied and claimed in print that Schanot supposedly confessed to this.  The prosecution also claims Schanot cost Southwestern Bell $500,000 damage to secure themselves after Christopher entered their system and that Southwestern Bell is supposedly now hacker proof.  They claim Schanot was a co-conspirator in crimes against Southwestern Bell involving people Christopher never knew or even spoke to and involving over a dozen hackers and phreaks who haven't been arrested and others who haven't even been raided or questioned.
    • At the time of his arrest Schanot, 19, was living with the woman he was dating, Netta Gilboa, 38, who is the publisher of Gray Areas magazine ( - Christopher designed the web page and also wrote reviews for it).  The FBI has admitted both in court and in press reports that Schanot committed no crimes during the time he lived with Gilboa, but the bust was a result of Schanot's father calling in the FBI to supposedly help find his runaway son.  Although Gilboa was not questioned, raided or arrested, Gray Areas magazine as well as Gilboa's life and character have been the subject of both court testimony and dozens of erroneous media reports.  Gilboa and Schanot have not spoken out until today and although the case is still ongoing which restricts many juicy details, as much as possible will be said to try to correct the media reports, expose the father, Mike Schanot, for stalking, and to condemn everyone involved from the prosecution to the feds to fellow hackers.  Extensive presence of both federal agents from *every* possible agency and media is expected at this particular speech as the case is both sensational and ongoing.  For this reason, in order to protect Christopher Schanot's legal rights and privacy, as well as to prevent more charges or accusations against him, there will be no questions or comments allowed from the audience during this speech.  Persons wishing to have a specific question answered about the case can either ask Gilboa in advance or after the speech.  On the bright side, this expected abundance of feds will result in many more opportunities to win an infamous "I Spotted The Fed" T-shirt.
    • Christopher is requesting that hackers do not speak to the media about him and is asking that donations to help him be sent care of Gray Areas Inc. (PO Box 808 Broomall PA 19008).
    • Netta Gilboa is arguably the person who has gotten the furthest in the computer underground without ever committing crimes herself.  She is also possibly the person in the scene questioned the most times ever by law enforcement simply for the crime of talking to hackers.  Gilboa is the publisher of the award winning publication Gray Areas and is the author of "Elites, Lamers, Narcs and Whores: Exploring The Computer Underground" which recently appeared in the Seal Press book Wired_Women: Gender And New Realities In Cyberspace.  She has also been published in Phrack, Computer Underground Digest, Cult of the Dead Cat, Empire Times, Dupree's Diamond News, and many other paper magazines and electronic publications.  Gilboa holds an M.S. in Advertising and an M.A. in Sociology from Northwestern University and a B.A. in Journalism from State University College of New York at New Paltz.
    • Hated by some, loved and respected by others, Gilboa seems to polarize the 1200+ hackers she has interacted with.  Gilboa is one of the few journalists to ever take the time to get to know hackers before writing about them and to continue to try to work with them despite severe harassment of both herself and other people associated with Gray Areas magazine.  Gilboa's boyfriend, Christopher Schanot, is presently incarcerated without bail for computer crimes he allegedly committed before meeting her.  It should be noted that Christopher trusts Netta with both his life and with his story.  According to the prosecution he was certainly in a position to check her out thoroughly and decided to be with her regardless of the consequences.  The couple are now collaborating on a book tentatively titled Computer Genius which will reveal the real inner workings of the hacking subculture and raise questions about the feds, informants and security experts who are often equally dirty and who allow it all to continue while they gather "information," hack themselves, and stay employed.  Numerous Internet providers will be evaluated for their roles in these events.  It is also expected that manycurrent, defunct and prank groups in the warez, ANSI, hacking, virus and phreaking scene such as ACID, BOW, DPAK, ICE, IIRG, ILF, INC, LOCK, LOD, MOD, NSA, PHALCON/SKISM, NUKE, POSSE, R00T and WNOC will be explored as well.  One intention is clearly to clear the couple's names.  Another is to help Christopher gain recognition as an expert in the field.  The combination of their different perspectives of various events they each witnessed separately and together over the years is expected to be way more powerful than any book written by either of them alone or by some reporter who simply profiled hackers but did not participate in the events themselves.
    • Although Netta Gilboa has previously spoken everywhere from HoHoCon to PumpCon to Computers, Freedom and Privacy, her Defcon speech will be long remembered for its guts, candid revelations and for some of the shocking and chilling facts as well as the glaring questions behind the "Computer Genius" case itself.  Few people arrested choose to reveal their stories so publicly.  Don't miss it!

  12. Richard Thieme - The Symbiotic Relationship Between Networked Computers and Humans  (5.6M MP3)  (M4B)
    • A dialectic constituting a rising spiral of mutual transformation.
    • Richard Thieme has lived in Chicago, Madrid, London, Salt Lake City, Lahaina (Maui), and now Milwaukee.  Taught literature at the University of Illinois, wrote fiction.  Worked as an Episcopal priest for sixteen years in three cultures.  Now speaks, consults, and writes about the human dimension of computers.  His focus is transformation -- individual, organizational, global -- and the transformation of spirituality online.
    • Hacking redefines how we think of ourselves.  Redefines how we understand out possibilities for action in the world.  It's also a metaphor for new opportunities available to human beings now and in the next century.  Hacking is one way to practice living in transplanetary society.  That's why hackers are pathfinders for the next generation.  Spirituality is simply the way getting connected online translates into new kinds of community life.
    • Thieme consults on change, technology, and diversity for banks, insurance companies, law firms, schools, associations, government, etc.  "The Stock Market, UFOs, and Religious Experience" is done frequently for investment and financial people.
    • He writes about all this for magazines in many countries. Last four pieces (during last two weeks):
    • "Stalking the UFO Meme" - in Virtual City - when you're trafficking in symbols of symbols of symbols, the Net becomes a ten-dimensional dog chasing its own tails/tales.  How do you know what's real code when you're lost in a simulation of a hall of mirrors?
    • "The Future of Networks/the Future of the World" - in LAN (Australia) - the transformation of human consciousness -- spirituality, community,organizational life, art -- in a networked world.
    • "Japan On-Line" - in Computing Japan - the interaction of Japanese culture with Net culture and how it changes both.
    • "lost" - scheduled for Wired (August 1996) - what it means for the human psyche to lose the possibility of being lost -- or found -- an archetypal dimension of consciousness for as long as we can remember.

    • Mr. Shipley will present research covering an overview of a 2 year effort in massive multi-modem wardialing.  His findings will include some personal observations and the results obtained from scanning the San Francisco bay area.  When Mr. Shipley started this project he noted that there were no published research references to wardialing or documented statistical results of the types of equipment and computer networks commonly found on the POTS (Plain Old Telephone System) network.  Mr. Shipley decided to change that through his research.
    • Mr. Shipley is an independent consultant in the San Francisco Bay Area with nearly thirteen years experience in the computer security field.  Mr. Shipley is one of the few individuals who is well known and respected in the professional world as well as the underground and hacker community.  He has extensive experience in system and network security as well as programming and project design.  Past and current clients include TRW, DHL, Claris, USPS, Wells Fargo, and KPMG.  In the past Mr. Shipley has designed Intranet banking applications for Wells Fargo, firewall design and testing for WWW server configuration and design for DHL.  Mr. Shipley's specialties are third party penetration testing and firewall review, computer risk assessment, and security training.  Mr. Shipley also performs post-intrusion analysis as well as expert witness testimony.  Mr. Shipley is currently concentrating his efforts on completing several research projects.

  22. Prof. Feedlebom - Pirate Radio
    • If you have ever been slightly interested in operating your own micropower radio station, this is it.  Why to, How to, and how to not get caught.  Will also discuss the potential of legal micropower radio in the future.  Kind-of a how-to, kind-of a demo, kind-of a "let's make the FCC real nervous" kind a thing.
    • Prof. Feedlebom and Technopagan have operated "The Voice of Mercury" and the "Desert Crossing Radio" broadcasts for the last four years.  They are also responsible for strange radio emissions that have been heard in the Los Angeles area on 104.7 MHz.

  23. Trask - Hacking the Big Iron: Security Issues in Large Unix Environments
    • I will be using the Sun Ultra Enterprise 10000 and IBM SP/2 as examples of how some of the newer, bigger Unix systems (which are increasingly being used for jobs previously performed by mainframes) present some interesting challenges in the area of system security.  As you may know, the Ultra Enterprise 10000 is a SMP system that can be configured with up to 64 processors, which may then be partitioned into a maximum of 8 independent partitions.  The SP/2, on the other hand, is an MPP architecture that can be configured with up to 64 8-way SMP nodes.  These two architectures are different in almost every way, however both are extremely fast, and both have some security concerns not present in more traditional Unix systems.  What I have found is that the security problems are surprisingly similar between the two types of machines.
    • By failing to consider all aspects of security when implementing the system management tools provided with these computers, the vendors are selling million-dollar-plus products that are less secure than typical end-user workstations.  I contend that as unix offerings start providing mainframe class computing power, they need to also look towards providing mainframe class security.
    • Trask dropped out of high school about a month prior to graduation.  After working at Wendy's, Wal-Mart and Texaco for a few months each, he decided that he would rather be a Unix sysadmin.  He lives in 602 with his beautiful fiance (mgd) and is currently employed by American Express, where he gets to play with all sorts of expensive toys.

    • Video  (103M RealMedia)
    • As policy and the economics of a world-wide economy force us to attempt an information based economy, the manufactured concept of intellectual property becomes paramount.  Our preeminent corporations have shifted from GM and Ford to Disney and Microsoft; our government struggles to develop and globally enforce laws to protect the profitability of IP.  These laws are intrinsically at odds with the free and unfettered exchange of ideas which is central to the validity of democracy.  But IP law is built on a weak legal and moral foundation, and it is far from clear that an IP based economy is viable.
    • David Gessel spent his childhood hammering steel in front of a coal-fired forge as a blacksmith's apprentice for seven years.  He then went to MIT to get a degree in physics where he focused on robotics and precision engineering.  Switching coasts, David joined Apple's Advanced Technology Group and worked on various things including pen-based computers, LCD technology, and digital cameras.  After ATG, David worked at Interval Research Corp, researching rapid design/prototyping technologies for mechanical systems.  David is now CTO of Spinner, Inc., a startup developing QTVR technology; VP of Engineering for Nebucon, Inc., a startup developing secure Internet services for small businesses; and contracts mechanical design services bicostally.

  26. Marc Briceno - Smartcard Hacking for Beginners
    • Smartcards are a marvelous tool for the security software developer.  Their small form factor and tamper resistant, though not tamper proof, packaging allows for numerous applications, such as secure key storage and encryption.  Unfortunately, many software developers still consider smartcards difficult to work with.  No doubt largely due to the fact that vendors have so far failed to provide sufficient information and development tools.  We will introduce SCARD, a free, cross-platform smartcard development, analysis, and integration tool.  No longer does the smartcard-curious individual have to learn obscure low level smartcard commands.  If you know how to use a UNIX shell or Windows NT, you can use smartcards.  There will be a demonstration of several cryptographic, electronic cash, and GSM cards.  The audience is encouraged to submit any smartcards in their possession for analysis.
    • Marc Briceno is the Director of the Smartcard Developer Association, the only vendor-independent smartcard industry association.  The SDA's member base is comprised of smartcard and security experts in Europe, Asia, the Americas, and Australia.  The SDA distributes universal smartcard analysis and integration tools to software developers worldwide.
    • Mr. Briceno coordinated the efforts leading to the discovery and break of COMP128, the GSM digital cellular telephony authentication cipher.  Mr. Briceno is a senior advisor on digital telephony issues to an international development effort engaged in designing low-cost phone encryption devices and a consultant to memory chip forensic data analysis teams at several major universities.

  36. Jason Scott - TEXTFILES, G-PHILES AND LOG FILES: Remembering the 1980's through ASCII  (17.2M MP3)  (M4B)
    • In the 1980's, life started to move online, bringing with it all the wonder, terror, and breadth of human nature.  Most markedly, an entire generation of teenagers turned their energies and efforts onto this growing culture and turned the world of Bulletin Board Systems into a combination street corner and clubhouse, sharing their knowledge, lying and bragging into infamy, and creating a shared experience that lasts in their hearts and minds to this day as they become the foundation of the Internet Society.  While the unique forces that combined to make BBSes the experience they were have since shifted and formed other cultures in the years since, a feel for the 1980's can be found in the Textfiles (also known as g-files or 'philes') that nearly every self-respecting BBS traded, offered, or created as a matter of gaining notoriety (and more importantly, callers) in a sea of similar voices.  In these textfiles, readers can reminisce or learn anew about what the BBS experience meant to those who lived through it, and easy parallels can be drawn to the 'scenes' that are now thriving online today.  This talk will attempt to give historical perspective and narrative to the BBS 'scene' of the 1980's, presented by a user who was around for a good portion of it and took notes.  Expect shouted refutations from the audience and eerily familiar battles waged across the message boards to live again.
    • Jason Scott (Formerly The Slipped Disk) has been an observer and participant in the world of BBSs since about 1982, cutting his teeth on Boards such as OSUNY, Sherwood Forest II and III, Milliways/Outland, The Dark Side of The Moon AE/BBS, as well as hundreds of others.  His experience in BBS culture of the 80's ranges from Compuserve and The Source to Deversi-dials, AE Lines and anything else that gave a carrier when you called it.  He is best known as the SysOp of The Works BBS, a textfile-only board that he ran from 1986-1988 before switching to SysOp-At-Large from 1989 to the present.  Realizing an entire generation's shared lore was being diluted and lost, he has started the site, dedicated to preserving all things ASCII from the 1980's.  This web site is slowly killing him.

  43. David Sobel - Internet Anonymity Under Assault: The 'John Doe' Lawsuits  (20M MP3)
    • Several recent court cases around the country highlight an increasingly popular litigation tactic: the use of civil discovery to unmask the identities of anonymous Internet posters.  In the last few months, a growing number of corporations have issued subpoenas to Internet Service Providers (ISPs) and operators of online message boards seeking to identify and locate individuals who posted material that the companies, for one reason or another, find objectionable.  A spokesman for Lycos recently told Salon Magazine that the firm receives subpoenas on "pretty close to a regular basis."  The underlying allegations in these cases include defamation, misappropriation of trade secrets and securities law violations.  Many observers worry, however, that the legal tactic can easily be used to intimidate potential critics into silence and destroy the anonymity that has contributed to the Internet's explosive growth.  David Sobel will discuss these cases and efforts to protect online anonymity.
    • David Sobel is General Counsel to the Electronic Privacy Information Center in Washington, DC, where he has litigated numerous cases under the Freedom of Information Act (FOIA) seeking the disclosure of government information on cryptography and privacy policy.  Among his cases are those involving Operation Sun Devil, the Clipper Chip, the FBI's Digital Telephony wiretap proposal and the Secret Service's Pentagon City $2600 raid.  David served on the Association for Computing Machinery's Special Panel on Cryptography Policy, which produced the report "Codes, Keys, and Conflicts: Issues in U.S. Crypto Policy."

  44. Jericho - Fakes Walk Among Us
    • The recent explosion of the security industry has found itself littered with newcomers, all 'experts' in the field.  Unfortunately, many of these 'experts' are nothing more than self proclaimed windbags that are no more qualified to help you with security than your local 6 year old.  How do these charlatans manage to find work?  Why are they accepted?  More important, how do you distinguish legitimate security professionals from the fakes?  These are valid concerns in today's security community.  Answers to follow?
    • Jericho is a security consultant (read: not an expert) working almost full time these days.  His travel has taken him to standard corporate networks, to consulting for wacky spooks that everyone fears.  On top of run-of-the-mill consulting, he has participated in network analysis via penetration testing, computer forensics and more.  He hates crowds.  :)

  46. Christian Hedegaard-Schou - What is Open Source?
    • This talk will focus on what open source is, what it isn't, debunking some myths, showing some examples, and giving reasons why open source is ready for the real world.  This talk is primarily aimed at government and corporate IS/MIS/IT staff and managers, but anyone who's curious as to what this "open source" thing is they've heard so much about in the past months are encouraged to attend.
    • Christian Hedegaard-Schou is a private contractor and consultant who first embraced opensource about 5 years ago when he discovered Linux and installed it over his DOS partition.  He's never gone back.  Since he first discovered Linux he also played with FreeBSD and NetBSD on various architectures, and has been a proponent of Free software, GNU, and the newly defined "open source" movement.

  47. Bennett Haselton and Brian Ristuccia - The "Anti-Censorship Proxy" and Technological Circumvention of Internet Censorship
    • Brian Ristuccia's Anti-Censorship Proxy (ACP) is a tool for circumventing network-level Internet censorship.  It combines functionality of older software such as PGP, Anonymizer, and steganography software, enabling Internet users to bypass firewalls and proxy servers without detection.  ACP can be used to circumvent firewalls used by China and Saudi Arabia to block criticism of their governments, or to bypass software used in American schools to censor pages about contraception, animal rights, and many non-Christian religions.
    • These countries and institutions are likely to crack down on the use of such software, provoking an "arms race" between ACP developers and their opponents.  (The use of strong encryption in ACP may even conflict with some countries' import/export regulations.)  This talk will describe the ACP and look at some of the directions that such an "arms race" might take, as well as describing real-world implementations of network-level censorship (in China, Serbia, the Middle East, as well as many U.S. schools), what kind of content is censored, and how the ACP could be used to bypass these restrictions.  More information at or
    • Bennett Haselton has been publishing studies of Internet censorship software since 1996.  His reports have been used as evidence in First Amendment court cases filed by the ACLU and People For the American Way, and he has been invited to speak on Internet censorship at Computers Freedom and Privacy 99, the American Library Association national conference, the ACLU of Ohio annual conference, InfoWarCon 99, and Spring Internet World 99.  Peacefire's reports criticizing censorship software have been featured on CNN financial news, MTV, Court TV, and MSNBC.

  48. Charles Faulkner - Hacking Human Minds
    • Human expertise is not found in the sum of explicit practices or algorithms.  It's in the experience, mental models and heuristics of individuals.  Invisible to current Knowledge Engineering, psychology and (most) linguistics, these 'rules of thumb' are available (can be hacked) through specific pragmatic, syntactic, and semantic 'filters/handles' that can be detected, influenced, and transferred.  Applications / instantiations to humans achieved.  Computing and human/computer interface applications sought.
    • Charles Faulkner is a hacker (modeler, in polite society) of human experience and expertise whose projects have included language acquisition, futures trading, metaphoric communication, and object oriented software testing.

  49. Michael Peros - Detecting Wiretaps
    • This year I would like to speak about how to identify body wires, recorders and government informants.  Also I have verified from a very reliable source that President Clinton passed a wiretap bill through executive order of the White House allowing the Federal Government to wiretap and intercept electronic-oral communication without a warrant.  This came into law as of January of 1999.  He did not have to go in front of Congress to bring this into law.

  3. noise - Anonymous Remailers: The Importance of Widely Available Anonymity in the Age of Big Brother  (14.7M MP3)
    • Video  (30.3M RealMedia)
    • From the golden days of the Penet pseudononymous remailer, to Janet Reno's call to squelch Internet anonymity, anonymous remailers have played a vital and oft-hated role in making the 'Net safe from Big Brother.  People regularly use anonymous remailers to avoid spam, to speak their minds without fear (of peers, family, employers, or governments), and to stay out of search engine indices.  Like nearly any other technology, anonymous remailers can also be used by "criminals" to do "criminal" things.  Under this guise, the government wishes to outlaw or severely restrict access to anonymous remailers.  Remailers are not difficult to use.  They're not prohibitively difficult to run, either.
    • "The only way the public remailer network will survive, is if more people start setting up remailers.  Even if all the current remailers never get shutdown by the Powers That Be [TM], people do tend to move, change lifestyles, pass on, lose their jobs or lose the time to run a remailer.  Remailers go away.  Change is the constant in life.  We need more remops if the system is to survive." -- Shinn Remailer Operator.
    • History, current status, and known attacks on Type I/II remailers will be the focus of the talk.
    • noise holds a BS in CS from some university and will be attending her second year of law school this fall.  She runs the noisebox anonymous remailer, helps the Electronic Frontier Foundation, and delights in holding heated debates with bureaucrats.  noise thinks the world would be a better place (tm) if it had more cypherpunk lawyers.

  9. Gregory B. White - The USAFA Cadet Hacking Case: What Both Sides Should Learn About Computer Forensics  (13.2M MP3)
    • Video  (7.8M RealMedia)
    • Basically, I'll discuss the case that went to trial in the spring of '99.  I was the Deputy Head of the Computer Science Department at the USAF Academy at the time and was asked by the cadet accused of "hacking" to help with his defense.  I testified at the trial as an expert witness for the defense.  I sat at the defense table throughout the trial serving as their "computer expert."  Basically the trial was a comedy of errors by the prosecution - law enforcement, and the cadet's attorneys alike.  The cadet was involved in IRC, but the law enforcement types and prosecution became convinced that he was the "hacker" (afterall, everybody KNOWS that IRC is nothing more than a place for hackers to trade information on how to break into computers - the actual sentiment expressed by the investigators).  I had up to that point spent the majority of my time in the Air Force trying to protect systems and to catch those who broke into AF systems.  This case really shook me as I saw the LE types latch onto the smallest of indicators and blow them into a full blown felony case (the cadet faced 15 years in Leavenworth had he been convicted of all counts).  What I will cover in the talk is:
    • 1.)  Background of the case.  2.)  The "evidence" the prosecution thought they had.  3.)  The many possible areas where clues might have been found had either side known where to look (or asked anybody who knew anything about it).  4.)  What lessons can be learned from this case.  Those from the government and industry need to know where to look if they want to catch folks (and if they want to make sure they don't make fools of themselves) and those who might find themselves accused someday need to know how to help their attorneys find clues that could exonerate them.

    • Video  (34.3M RealMedia)
    • The recent surge of interest in security has been a boon for those developing IDS systems.  Unfortunately, the IDS advancements have been disproportional in the realm of Network IDS - with host-based IDS lagging behind, only able to detect breaches after the incident.  This state of affairs offers administrators, faced with the looming threat of intruders gaining access to their systems via legitimate channels, little protection beyond hardening and continually patching their systems.  An intruder need only find one hole, the administrator - all of them.  During this session, the Saint Jude project will be presented.  Named after the patron saint of hopeless cases, the Saint Jude project is an IDS project that hopes to deliver a model and implementation able to stop a root compromise dead in its tracks, irregardless of the exploits method.

  12. Ron Moritz - Proactive Defense Against Malicious Code  (10.7M MP3)
    • Video  (35.1M RealMedia)
    • Anti-virus software is an important part of a well-devised security policy, but reactive virus detection is not versatile enough for the demands that will be made on businesses engaged in e-commerce.  The year 1999 began with the birth of the Happy 99 virus - a harbinger of things to come.  Happy 99, plus Melissa, PrettyPark and the worm are all examples of third generation of malicious replicating code, designed to exploit the Internet for their rapid proliferation.  A variant of, called MiniZip, managed to hide itself from antiviral utilities and spread at an amazing rate around the Internet at the end of 1999.  Such programs, which launch new malicious code attacks, create "first strikes" against systems and networks.  Allowing untrusted code to execute on the corporate network may not be suitable for your organization.  But corporate security policies that block network executables adversely affect the evolution of the Internet, extranet, and intranet.  While no security implementation is absolute, functionality is not achieved by disconnecting users from the network and preventing access to programs.  Therefore, proactive defense against first-strike attacks is required today.
    • Almost all web sites today contain mobile code.  Many of the powerful business (e-commerce) applications you need and use are written with mobile code.  Consequently, net-enabled malicious software is likely to increase in prevalence and successful utilization.  The factors accounting for such a prediction are the ease by which users are duped into double-clicking on malicious Email attachments and, the ease by which the sources of those Emails are automatically spoofed to seem to come from a boss or from an Email or instant message friend.  Traditional pattern matching approaches are incomplete, out-of-date, and ineffective and were never designed in preventing a series of new generation attacks based on malicious mobile code and Trojan executables.

    • Video  (37.0M RealMedia)
    • You've just spent $10,000 on network IDS from a trustworthy company (obviously trustworthy because the vendor spends beaucoup $$$ on marketing).  You are satisfied with the purchase because you're catching all these script-kiddies who think they are putting one over on you with their "stealth" scans.  But then something bad happens: your servers get hacked through your firewall, and that expensive IDS never utters a peep.  How did this happen?  The root of the problem is that most commercial IDSs are little more than anti-script-kiddy tools and cannot detect ueberhackers.  This talk will show how to evade these IDSs using popular tools like whisker and fragrouter.  It will also reveal for the first time additional secret techniques used by ueberhackers.

  16. Jon Erikson - Number Theory, Complexity Theory, Cryptography and Quantum Computing  (10.3M MP3)
    • Mr. Erikson will talk about number theory, complexity theory, cryptography, and quantum computing.  The basics of number theory pertinent to cryptography will be covered, including modular math, the Euclidian GCD algorithm and Euler's totient function and theorem.  Complexity theory and tractability will be explained to give a feeling for what a 'hard' problem is (NP vs P) and algorithmic runtime and Big-O notation with respect of input size will be explained to show why factoring the product of two large prime numbers isn't trivial.  Then the RSA encryption/decryption algorithms will be derived from scratch, using modular math, GCD, and Euler's totient function.  A few factoring methods will be described, to emphasize the complexity involved in factoring the product of two large prime numbers.  Then the basics of quantum computation will be explained; superposition, EPR state, decoherence, controlled NOT gates, and entanglement.  The actual quantum mechanics will be skipped to focus on the algorithms.  Peter Shor's quantum factoring algorithm will be explained and demonstrated, breaking RSA in two steps.  Lov Grover's quantum search algorithm will be explained and it's ability to brute force anything in sqrt(N) steps will hopefully be apparent.  Since most conventional encryption will be shown to be insecure, a few quantum encryption techniques will be covered.  Q&A afterwards, time permitting.
    • Jon Erikson was the product of a 6th grade science fair experiment in human genetics by little Snirk Cojeno on planet Vega 7 (His parents helped a little bit).  After the fair was over, Jon was sold as slave labor by the elementary school to the Orb Night intergalactic casting and modeling agency.  Due to his dashing good looks and human neck, Jon quickly found himself the poster boy for Zarlak's explosive human restraint collars; his likeness plastered all over space billboards and magazines.  The fame went to his head, and Jon soon attempted to join the unions, despite the strict regulations against human slaves working like the frees do.  He was sentenced to 160 years on the Prison Planet Earth.  As if exile to Earth wasn't bad enough, moments after landing, he was quickly carted away to Area 51 by the U.S. Government, only to be traded to a Japanese research group in exchange for some rare Pokemon cards by an agent named Jose Ronnick.  In Japan, the brilliant Dr. Kenji Cronos and a lab tech named Michelle began an experimental open-brain surgery procedure on Jon, hoping to teach him about human emotion.  Something went horribly wrong, and when the anasthetic wore off, Jon woke up in an empty operating room, with a giant hole his skull.  All the colors began to taste like blue again, and he panicked, plugging the hole with paper mache and running into the streets to forage for himself.  With 142 years left in his prison sentence, Jon began his own scientific research in the realms of cryptography, parallel algorithms and processing, artificial intelligence, and complexity theory, and has lived as a student, teacher, actor, director, writer, DJ, programmer, researcher, and entrepeneur.  And he's sorry that she has to miss out on so many grand adventures...

    • Video  (20.0M RealMedia)
    • The speech will discuss hacking firewalls and filtering routers by spoofing IP and MAC-addresses.  Two different spoofing techniques will be presented.  Ian will first talk about what to eavesdrop (with siphon, dsniff, and tcpdump) and what kind of information one will need for these examples to work.  Secondly Ian will show how to setup a working source route (full connection) with netcat through a filtering router.  Then Ian will show how to setup the network on a Linux to be able to IP-spoof (with full connection) through a firewall if you sit on a untrusted network, U, between a trusted network, A, and the server, S.  Both examples will be explained step by step.
    • Ian Vitek works as a full time penetration tester at Infosec, Sweden (The page is in swedish).  He is right now researching within Media Access level security and LDAP security (which is a big unexplored hole).  He also thinks that modems are underestimated hacker tools.

  22. Bennett Haselton - A Protocol that Uses Steganography to Circumvent Network Level Censorship  (14.3M MP3)
    • Video  (47.0M RealMedia)
    • Many trivial techniques are already available for circumventing firewalls and proxy servers that monitor or censor network traffic -- for example, if your firewall blocks CNN, someone could setup an unblocked site outside the firewall where you can type "" into a form and retrieve the page contents.  The problem with these "protocols" is that they make it easy to get caught, if the censors know what to look for -- for example, a GET or POST form field containing "http://" is trivially easy to detect.  Even an encrypted protocol would still be easy for censors to detect, without breaking the encryption -- just the fact that you're *using* a tool for circumventing the censors would often be enough to get you in trouble.
    • What we have designed is a protocol that uses steganography to circumvent network-level censorship, so that the protocol is undetectable to censors.  We explain why some naive solutions to the problem -- such as hiding information in a long, dynamically-generated URL which is sent to an outside "friendly" site, or hiding information in cookies -- are not steganographically secure.  Our protocol hides information in "innocent-looking" text queries that pass through the censoring proxy undetected.  The page contents are encrypted and embedded in more "innocent-looking" content that is sent back to the browser.
    • This sounds simple, but the mathematics of using steganography to make a protocol *undetectable* turn out to be infuriatingly complicated.  Much of the talk will be devoted to attacks against the system that we didn't consider the first time around, and why more naive solutions may fall to these attacks.
    • Bennett Haselton has been the coordinator of since its inception in 1996.  Peacefire opposes censorship that targets Internet users under 18, and maintains that profanity and smut on the Internet are not, in fact, "dangerous" to anybody, as most lawmakers and blocking software companies have made them out to be.  Peacefire publishes research into different Internet censorship programs and technologies, their shortcomings, possible misrepresentations by the companies selling them, and (most popular) how to get around them.

    • Video  (30.4M RealMedia)
    • When might international computer hacking become an act of war?  Some within the hacker community have felt that international hacking wasn't being done right by the DoD - it could be done much more effectively and efficiently if left to the experts - civilian hackers.  This position is interesting, but is it appropriate?  What ARE the international implications of electronic network information operations which target foreign actors or states?  How far can an operator go before his acts become an "act of war?"  What type of retaliation by a target country is permitted under international law and custom?  What are the rules?  Whose rules apply?  In a world where hacker groups are so bold as to declare war upon a nuclear-capable major world power, and countries take military action against non-state actors geographically located in a non-hostile state, these thorny issues attain paramount importance.  This presentation explores these issues in an effort to help shed light upon this "dark secret" of international relations.

    • Video  (42.9M RealMedia)
    • This is a technical talk aimed at people who have already been exposed to buffer overflows and want to learn more.  The talk assumes the audience has at least some knowledge of CPU's and processes.  For those of you who already understand buffer overflows, this talk will be a refreshing discourse on technique.  We will show how the injection method can be decoupled from the payload.  We then explore the details and challenges of injecting code into a remote process.  We will also explore the payload, the encoding methods, and how to dynamically load new functions.  Lastly, we discuss the possible effects of a payload, including network worms, virus, and rootkits.

  26. Mike Scher - What is DNS Alternate Roots?  Why Does Internet Suck?  (7.7M MP3)
    • Video  (25.5M RealMedia)
    • Recently, the overlaping space among DNS, the design of browsers and search engines, international, national, and local trademark interests and law, have come to a head.  A sprawling organization dubbed ICANN has taken over what used to be a task that sat squarely on one man's shoulders.  The tensions are largely the result of ignorant (and purposeful) confusions of the purposes and functions of the various Internet name and resource locating systems.  In this talk, we will discuss what a DNS root fundamentally IS, and the factors that keep a unified name service root in place despite many pressures to decentralize DNS root services.  We'll then look at the ways in which decentralized or alternate roots could be (and have been) implemented, and their implications for trademark and software politics and design.

    • Video  (30.1M RealMedia)
    • In days gone by, microprocessors dealt in units of 8-bits at a time, and names such as Commodore, Atari, and Apple (as in "Apple ][") ruled the land.  Intrepid hackers of amazing skill and talent worked their magic with limited resources, producing code that was a thing of beauty.  The days of the widespread 8-bit desktop computer are past, but the 8-bit processor itself is not gone.  It has gotten faster, added some peripherals and picked up some of the architectural features of it's larger later siblings, largely lost it's external memory, and gone into hiding as the ubiquitous microcontroller at the heart of embedded systems too numerous to count.  Microcontrollers offer an excellent opportunity to recapture that spirit of the late 70's when 1K of code was a lot, while working with modern day technology.  In this one hour talk, Phil King will describe how to setup a microcontroller development environment on a hacker budget and use it to learn and develop nifty 8-bit embedded system toys.  The talk will be framed by descriptions of building an embedded keyboard sniffer with an Atmel AVR family microcontroller.
    • Phil King is a hardware design engineer with 8 years of experience in various Silicon Valley hardware and software jobs.  He received his BSEE from Stanford University in 1992, and an MSEE with an emphasis in computer networking (also from Stanford) in 1998.  He is currently preparing to teach EE-281, the Embedded System Design class, at Stanford University this fall.

  51. Sarah Gordon - Virus Writers: The End of the Innocence  (8.3M MP3)
    • Video  (26.9M RealMedia)
    • Earlier research has empirically demonstrated the cyclic nature of virus writing activity: As virus writers age out, new virus writers take their places; enhanced connectivity amplifies the existing problem and various technical factors result in new types of virus writers surfacing and the cycles repeat.  However, a new variable has recently been introduced into the cycle: legal intervention.  The virus writing community now has experienced visits by concerned law enforcement; there have been arrests and sentencings.  New laws are being enacted, and acted upon.  Thus, the virus writing scene is no longer a casual game of kids on local BBS.  What has been the impact (perceptually and operationally) of these visits, arrests, and most importantly, the (yet to be imposed) sentencing of David Smith.  In other words, as the virus problem gets more and more attention, where are we actually going in terms of shaping acceptable behavior in our virtual communities and what, if any, impact are these legal interventions having on the impact of viruses impacting users?  In order to produce a scientifically meaningful answer to this question, this pre- and post-test study examines pre-sentencing opinions of the impact of the visits/arrests/sentencing and compares these findings with those from post-sentencing opinions.  Opinions are interesting and must be considered, as we know the opinions of today shape how people behave in the future.  However, we are also concerned with immediate impact.  To this end, impact will be examined in terms of viruses found both ItW and on the WWW, as a function of time with parameters being pre/post sentencing.  In particular, we are interested in any discontinuity noted in the graph of viruses both ItW and on the WWW, and in online references to legal concerns.
    • The conclusions will obviously depend on the actual results, but there appear to be essentially one of two scenarios:
    • 1.  The pre- and post-tests studies will demonstrate significant differences.  Thus, proponents of tough police follow-up of virus writers will have some hard evidence that this actually has a financial value, as well as a societal impact.
    • 2.  The pre- and post-test studies will demonstrate no appreciable difference.  This means that we need to re-evaluate the worth of pursuing virus writers as a useful way of curbing the problem and evaluate the wisdom of spending large amounts of public funding to pursue this avenue of defense.

  53. Natasha Grigori - Hacktivists to Activists - Make the Transition  (8.9M MP3)
    • Video  (19.3M RealMedia)
    • In 1999 the ACPM was formed with the goal of removing child pornography on the Internet via any means possible.  After an initial announcement on HNN, and recruitment at DEFCON 7, we began the daunting task of shutting down child porn sites.  Initially successfully, we found that the sites we took down would come back up after a few days or weeks.  Not only would they return, but it became increasingly more difficult to take them down.  We were not effectively removing sites, just making them stronger.  A change in tactics was necessary, and so the transformation to ACPO began.  The transformation into a "legit" activist group from our beginnings in the H/P/A community did not occur without its own pains.  Some felt we were becoming "soft" on child pornography and left.  Others joined, not deterred by our history.  We have come to form strong bonds with law enforcement internationally, and have had success at identifying both those that traffic and receive child pornography.
    • Recent articles in,, and have focused on ethical "hacker" groups fighting child porn have featured ACPO and, who is currently in the process of "going legit".
    • In my talk Natasha Grigori (and possibly Rloxy of will present the problems which convinced us that hacktivism was not the appropriate path, the transition process into an activist group, and the benefits the transition has has brought us.

    • Based on RedHat Linux, users can accurately simulate an enterprise network populated with real servers and workstations on a SINGLE COMPUTER (the system literally runs several real networked operating systems simultaneously inside one computer).  It also runs multiple firewalls, gateways, routers, VPNs, or any other network device.  Security experts (or hackers) can create a virtual network, populate it with Windows systems and then attack them with the latest exploits.  In addition, all packet traffic can be (sniffed) sent to a file or displayed in real time.  This provides security experts with detailed information about the nuts and bolts exchanges between networked computers.  Thus, software-programming flaws can be identified and exploited.  In addition, the system is a outstanding platform to create and test the most twisted of viruses.  The kicker is you can build a virus, instantly infect a networked OS, and then rapidly see the results.  If it doesn't work correctly, within seconds you can restore the infected windows OS to a virgin state, modify the virus, and try it again.

  3. Jason Peel - Cypherpunk Grade Covert Network Channels  (11.1M MP3)
    • Two parties, both operating in hostile network territory, need to communicate covertly via an internetwork.  They need to do so in a manner such that a well-resourced attacker cannot gain knowledge of the content of their transactions, nor even gain evidence beyond plausible deniability that discrete communication is taking place.  The assumptions made are extreme; it is understood that lives may be at stake.  Is the creation of such a clandestine network mechanism technically feasible?  Absolutely.  Should you be concerned about the implications of undetectable traffic?  Most definitely.  An initial R+D implementation in library form as well as proof-of-concept code built upon it will be presented.  By taking advantage of peculiarities in many fielded protocols, steganographic techniques applied to the network layers, and using dynamic polymorphism based on local traffic patterns and cryptographic control, the channel is effectively able to resist detection and attack.  Discussion concerning the theory, implementation, and political ramifications is welcomed.

  9. Mark Grimes - TCP/IP Intelligent Agents: The Future of Electronic Warfare and Defense  (11.0M MP3)
    • The study of artificial intelligence bring many treasures to the development of both offensive and defensive network tools.  Code can be designed to make "intelligent" decisions based on a presented data sample.  When rules are explicitly laid out by RFC to indicate proper connection handling, these rules can be mapped and recalled.  This would allow for an automated handling of network traffic with decision making enforced on next-packet injection.  The DEFCON speech will focus on Intravenous.  Information will be shared with regard to overhead handling, event priority, as well as database and sensor/decoder optimizations.  Examples in logic considerations will be broken down for simple attack scenarios.  The IV specific design constraints and project goals will be discussed, a maillist will be announced for open discussion about the code that has been developed so far, and improvements of the overall design criteria.
    • First, we will discuss what the word "intelligence" means and how it relates to source code.  Recent work has been in online data management and profiling (enough for an entire lecture on what's really happening) as well as side security projects, artwork, and 3D design work.  His next assignment is project manager on a building wide telemetry and control integration system with full accountability in real-time on a TCP/IP house net with full security implimentation, as well as physical buiding security.  We will explain the need for code that is not only self-aware, but aware of the environment it runs in.  We will briefly discuss the research conducted in the artificial intelligence field as it relates to TCP/IP networking and overall computer security.  Many developers are writing code with AI properties and fail to capitalize on it.
    • Second, we will discuss the state of tools/exploits today, and where they are headed tomorrow, in lieu of current security tools being seperate and disjoint.  Packet sniffers seldom share information with packet crafters and IDS systems seldom share information with network scanners, for example.  We will explain the need for agent code to assist in data collection, storage, retrieval and analysis for use within the scope of any tool that either runs interactively or in daemon mode for long periods of time.  Discussion of toolsuite integration so that the network auditing and network detection are a more seamless process.  Most exploits can be classified in only a handful of categories, most of which the discovery are based on custom scripts and source code analyzers.  We will then explain the future of network assessment.  We will explain where "non-intelligent" code falls flat, and how introducing rule bases, knowledge bases and a back-tracking method (memory), can allow an application to deduce plausible scenarios based on the data collected.  This, in turn, will allow an application to be able to react to situations based on mathematical probabilities and/or metrics to hopefully choose the correct answer(s).  Even without correct answers, it can still present the user with empirical data that may lead to a plausible next event.  The Nemesis injection routines will be used in Intravenous.  The threat of Nemesis by itself will be discussed with examples sited from published sources, and then will be contrasted with the introduction of AI componsents, that will make up the overall study, Intravenous (an agent concept model).

  17. Raven Alder - A Perl Script That Tracks DoS Attacks Across Cisco Backbones  (7.9M MP3)
    • Denial of Service attacks are well known in the security field, but in recent years distributed Denial of Service attacks have become more of a worry and a priority to ISPs.  Recognizing when a DDoS attack is crossing your network is important, and being able to shut it down at your network's edge is even more so.  But due to the increasing ease of spoofing the source IPs of a DDoS attack, correctly finding where the traffic is entering your network becomes more difficult.  Rather than being able to traceroute via normal routing methods, most tracing of spoofed addresses has to be done hop by hop, one router at a time.  In a large backbone, this can take hours, particularly when you consider that many DDoS attacks come from hundreds of different IP addresses.  There aren't many tools out there to aid NOCs in tracing these sorts of attacks.  Indeed, many NOCs are still forced to trace attacks by hand.  To address this problem, I have written a Perl script to trace DDoS attacks backwards through a Cisco-router network.  The script can handle spoofed IPs, and will run both on Cisco's older routers (7500 series) and on their Gigabit Switch Routers.  This talk will present the script and provide a guided tour through the code to explain how and why it works.
    • Raven Alder is a senior network engineer for a Tier 1 ISP, and hunts down DDoS attacks in the wild for fun.  In addition to supporting Cisco routers, Raven is also a Solaris/Linux/BSD sysadmin, and enjoys Shorin Ryu martial arts and particle physics.

  18. Marcus Andersson - Firewalling Wireless Devices  (11.9M MP3)
    • The different technologies today for providing IP-access over the air to handheld devices all pose some interesting questions about traditional security work.  How to firewall?  What is the physical differences of being on the "inside" versus the "outside" of the firewall?  How to implement prudent securitymeasures if there is no security on the physical layer?  Today, we can conclude that most base-stations used for radio LANs, regardless of technology (Bluetooth or IEEE 802.11) have coverage outside the building.  This means that if someone is in the parking lot, with a PC and a radio LAN connection, one is connected to the office LAN...
    • The presentation suggests some architechtureal workarounds to some of these problems, namely for example to put all handheld devices on their OWN "demilitarized" network, and not on the "inside" of the firewall.  Other suggestions are made on how to implement some security on the handheld devices themselves, in order to protect them from compromising the whole network, as an unsecured "endpoint" in such a network would do.  The topic of personal firewalls and automated virus-scanners for handheld devices comes in at this level.
    • Some issues regarding implementing cryptography in different layers of the OSI-model are discussed, as is both risks and verified securityholes with current cryptographical implementations on the link-layer (such as WEP).  A brief discussion on cryptographical protection and the impact on intrusion detection (the sensors can't see what happens if the traffic is encrypted) and virus-scanners (scanners can't scan encrypted mail) in included as well.
    • It is not in the scope of the presentation to suggest a best practice, but rather to give some information on the threats of these new technologies, so that risk management can make their own decisions based on that.

  20. Nick Farr - Designing Secure Interfaces "for Dummies"  (8.7M MP3)
    • The old addage holds there is an inverse relationship between usability and security.  The more user-friendly the system, the less secure it is.  However, recent user heuristics research may lend insight into how to design more usable, more secure operating system interfaces -- independent of the underlying OS architecture, AND the gullibility of the user.  By highlighting the graphical and subtexual cues recently highlighted in popular OS interfaces, the speech will cover how users are betrayed by them, either into a state of paranoia or a false sense of security.  The speech will show how both states can be used to exploit the system through the user.  As well, five guidelines for future interface design will be presented, showing how increasing the security of the interface can actually be used to increase, instead of restrict usability.  While the talk is theoretical, each guidline will be applied as integrated into the design of a work-in-progress Kiosk package currently under development.
    • Nick Farr recently graduated from the U of Michigan with a degree in Social Science, which included some graduate work at the School of Information in Human Computer Interaction.  He works as a developer for the School of Public Health at the University of Michigan.

  23. Daniel J. Burroughs - Applying Information Warfare Theory to Generate a Higher Level of Knowledge from Current IDS  (12.2M MP3)
    • The two greatest weaknesses of Intrusion Detection Systems (IDS) are the ease of which they may be evaded and their tendency to generate vast amounts of false alarms.  Sophisticated attackers are able to easily avoid detection, maintaining a low profile by spreading out the attack both in time and (network) space.  Meanwhile alerts are generated by normal user activity.  IDS have not yet reached a level where they can reliably detect and assess advanced attacks while being able to separate normal user activities.
    • This presentation discusses the use of information warfare theory, combined with multiple target tracking algorithms to generate a higher level of knowledge from current IDS.  Instead of looking at IDS as the final stage in attack determination, it becomes the first stage.  The IDS are treated as sensors on our network gathering information that is fed into a data fusion engine.  By gathering information from different types of IDS and other sensors distributed throughout one or more networks, we aim to generate a higher level of knowledge, a situational awareness, that paints a much clearer picture of the activity on out networks.
    • By combining and fusing data gathered from many independent networks, it is possible to move away from the traditional defensive posture of network security.  In its place we are given more of bird's eye view of the scene, and are able to see the activity of individual attackers spread out across many networks.
    • This presentation is based on research being conducted at the Institute for Security Technology Studies (ISTS), a federally funded research institute housed at Dartmouth College.  A demonstration of the data fusion/target tracking system will be provided during the presentation.

  26. Dr. Ian Goldberg - Arranging an Anonymous Rendezvous: Privacy Protection for Internet Servers  (12.3M MP3)
    • As the Internet grows in popularity around the world, we are beginning to see clashes between individuals and governments from different cultural backgrounds.  Corporations, organizations, and legislatures are using local laws in order to enforce their wishes on others worldwide.  Much work has been put into producing privacy-enhancing technologies that protect clients of online interactive Internet services.  In this talk, we present the "rendezvous server," a primitive which allows the transformation of any such technology into one which can equally protect the providers of those services.  It is our hope that being able to provide privacy for providers of online services, such as mailing lists, discussion groups, web sites, file servers, and chat rooms, they will be less susceptible to attack, and so will help prevent the Internet from becoming a place where the powerful can control the availability of content worldwide.

  41. Enrique Sanchez - Distributed Intrusion Detection System Evasion (DIDSE)  (7.2M MP3)
    • A fast connection is the new era, but your IDS system can handle it?  Can your operating system can handle it?  Can you handle it?
    • A DDoS is not the worse thing that an attacker can do in a distributed way.  A evasion attack can take place while your IDS is just dropping packets, while it is just there checking an innumerable amount of unused packets with unused connections.
    • There is no tool such as this, or is it?  DIDSE distributes the attack ranging the amount of packets to be sent to the network to cause a flood to even modem connections in a timing and hidden way the is virtually impossible to hide it, combined with some accuracy in penetration an attacker could easily bypass the new era security systems.  He can bypass your IDS.

  43. Richard Thieme - Hacking a Trans-Planetary Net: The Essence of Hacking in a Context of Pan-Global Culture, the Wetware/Dryware Interface, and Going to Europa  (14.1M MP3)
    • When Richard Thieme spoke at DEFCON 4, he said hacking was practice for trans-planetary life in the 21st century.  Well, guess what?  It was.  But a changing context has also changed what hacking looks like.  Context is content, and what was hacking at MIT on a PDP-6 just doesn't cut it any more.  The essence of hacking is the same, but the game is played differently.  When space war involves holographic image projection, cloaking devices, multispectral camouflage, micro-know-bots and the creation of synthetic environments that an adversary thinks are real... when cells are switched on to conduct heat and electricity... and the exploration of Titan and Europa make Mars and the moon look like inner suburbs... hacking means more than knowing how to spray paint a website or shut down a server.  Hacking means an artist's imagination, an obsessive hunger for knowledge, and a deep understanding of cyborg humanity. Thieme illuminates the topography of that weird landscape.
    • Key concepts: Context is content (i.e. what makes sense in one context no longer makes sense in another) what is wise in one context is insanity in another; hacking in its essence is a way to approach life with identifiable qualities and characteristics - some are innate and some can be learned.  The ones that can be learned and how to learn them are spelled out; the attributes of hacking as it evolved in the sixties, if translated whole hog into the 21st century, make you look like a dork; it's not about being a script kiddie, doing DDoS attacks, or leaving graffiti - it is about the tools of imagination, the weapons of the mind, in a world of widespread deception; the practice of deception - the creation of illusion, the use of misdirection, the lethality of ridicule - are examined in relationship to hacking as the quest to know the truth; specific scenarios will be described, using the most current human resources, including war in space; the fusion of information war and space war through the "information web;" the changing definitions of humanity at the wetware/dryware interface, with emphasis on materials science and advances in brain enhancement; how life in space changes people and changes the species; and the bottom line - how the real attributes of hacking can be ported into this Borg world and used imaginatively, mischievously, and with a light touch to give real style to one's hacking and transform one's cyberlife into a work of art.

  49. Keith Nugent - Windows 2000 Security: How to Lock Down Your Win2k Boxes  (23.0M MP3)
    • Windows 2000 provides a lot of new security features that were previously not available in earlier versions.  The NT line, however, has never been considered very secure right out of the box.  We'll be talking about how to use NTFS permissions, Default Security templates, Custom Security templates, and Group Policy to lock down a Win2k box.  We'll look at what level of security is applied by default on a Win2k box, how to analyze these settings against proposed settings, and how to apply identical settings across multiple boxes.
    • Keith Nugent has been playing with computers since his father first brought home an Apple iic.  Being the youngest child, it thrilled him to no end to have something that would respond to HIS commands, as he was used to being the one who followed commands.  Keith toyed with Apples and PC's for the next few years while he did other things, like grow up, go to college, run a business, and drive a tractor-trailer around the country.  Then, a few years back, as tends to happen, he was the guy who was always fixing, operating, and training others on the computer.  So he gave in and became the network administrator.  Now years later, he's given up the pager and 3 a.m.-the-sky-is-falling phone calls of network administration to train full time.  Keith is currently the technical training supervisor for a large computer training center in Chicago, IL.

  53. Dmitry Sklyarov & Andy Malyshev - eBooks Security - Theory and Practice  (8.0M MP3)
    • Security aspects of electronic books and documents, and a demonstration of how weak they are:
    • "Standard" PDF encryption, ROT13 (used by New Paradigm Resources Group, Inc.), FileOpen (by FileOpen Systems), SoftLock (by SoftLock Services, Inc.), Adobe's Web Buy, Adobe's eBook Reader (GlassBook Reader), InterTrust DocBox plug-in.
    • Documents publishing in electronic form have a lot of advantages against traditional on-paper publishing.  You could easily find list of such advantages on web server of any company, which provides eBook solutions.  But nobody perfects, and there is one big problem that related with eBooks.  Information in electronic form could be duplicated and transmitted, and there is no reliable way to take control over that processes.  There are several solutions from different companies that were developed to prevent unauthorized distribution of the electronic documents.
    • My name is Dmitry Sklyarov.  I'm employee of the ElcomSoft Company.  As we have demonstrated in our speech on Black Hat Win2K Security (February 2001), encryption in Microsoft Office documents is very weak and password protection may be removed without any problems in most cases.  In this speech, I'll try to cover password protection aspects of electronic books and documents.  The most attention will be paid to documents in PDF format.

  54. HC - NTFS Alternate Data Streams  (8.0M MP3)
    • Windows NT and Windows 2000 have powerful graphical user interfaces that make the job of assessing the security condition of and securing these operating systems considerably easier.  Changing the bad logon limit is, for example, relatively easy to both understand and do in both of these Windows operating systems.  Providing adequate security does not, however, always involve working with mainstream features of applications, operating systems, and networks.  Alternate Data Streams (ADSs) are an example.  This little-known feature available with the NT File System (NTFS) in WNT 4.0 and Win2k (RICH98) has been available since the advent of NTFS in the first WNT release, WNT 3.1.  Although this feature is relatively unknown by the vast majority of WNT users and administrators, it provides a potentially very powerful attack mechanism for malicious individuals intent on compromising and exploiting WNT and W2k systems.
    • What is an ADS?  How can ADSs be created and how can executables be run in them?  How can they be misused (e.g., by having malicious executables run in them)?  How can they be found?  This paper addresses these and other related issues concerning ADSs and security considerations.

  55. Dan Moniz - The Impact of P2P on Security in the Enterprise  (6.2M MP3)
    • Increasing democratization of the network means more and more users are finding interesting things to do with the resources at their disposal.  In the wake of watershed decentralized applications such as Napster, many commercial and open-source efforts are producing so-called "Peer-to-Peer" (P2P) or decentralized applications and computing frameworks.  The genesis of P2P, decentralization, and distributed computing as a fundamental architecture has serious implications for the way security is handled, not only in the wilds of public networks like the Internet, but also in closed enterprise environments.  Like it or not, users will be using these apps and participating in these networks.  It behooves every security administrator to become familiar with the nature of P2P systems and to understand both the potential threats and possible benefits of such systems, as well as to anticipate user adoption and related issues.
    • Dan Moniz is a Research Scientist and Chief Security Architect at OpenCola, a leading developer of Distributed Computing Infrastructure (DCI) software, including peer-to-peer (P2P) applications and reliable multicast systems.  His primary work to date has been in the area of security architecture for generalized P2P applications, protocols, and frameworks.  Previous projects have involved Digital Rights Management (DRM) systems predicated on true electronic rights inside capability-based secure environments as well as analysis and design of authentication protocols for distributed media streaming applications.  Before joining OpenCola in September of 2000, Mr. Moniz worked as a Researcher for Viasec Limited, a crypto software development firm, and contributed to their flagship email encryption server Consus, as well as additional internal research projects involving Single Sign-On (SSO) technology, biometric identification systems, smartcard tokens, capability-based systems, and security for mobile devices.  Mr. Moniz supplements this experience with several years of exposure and participation in the public infosec community at large.

  6. Fred Trotter - Operating System Fingerprinting Library  (8.7M MP3)
    • This is a fingerprinting library designed to bring together the fingerprinting capabilities of NMAP, QueSO and X (at least version 1).  Using this library you should be able to add operating system sensitive code to your favorite Perl, Java, C or C++ code.
    • At the same time the library will give you control over the execution of individual OS fingerprint tests.  If you are interested in writing OS sensitive code or researching OS fingerprinting then this talk (and the code) are for you.  Everything will be released GPL.
    • In his first life, Fred Trotter worked at the Air Force Information Warfare Center, and was a spook.  But, while the Air Force let him work on cool stuff, which was good, it paid crappy, which was bad.  So, Fred quit working as a spook and went to work for Rackspace.  And there was much rejoicing.  At Rackspace Fred Trotter tried to protect the largest installed base of RedHat servers in the world, and often succeeded.  Then that contract ended abruptly and there was wailing and gnashing of teeth, for Fred had been paid well, and had gotten used to bank.  Then, Lo, exault was hiring, and Fred Trotter applied and was hired, and there was much rejoicing, and the people did feast upon the lambs and sloths, etc.  Then after 40 days (more or less) exault was bought by VeriSign.  Then 40 days (more or less) later the VeriSign stock price plummeted, and the beatings given it by Wall Street were not just, or holy.  But, Verily, though his stock options were worthless, he still had a cool job with a cool company in a crappy economy; and there was much rejoicing.

  9. Dan Burroughs - Correlation & Tracking of Distributed IDS  (8.5M MP3)
    • Standard approaches to intrusion detection and response attempt to detect and prevent individual attacks.  However, it is not the attack but rather the attacker against which our networks must be defended.  To do this, the information that is being provided by intrusion detect systems (IDS) must be gathered and then divided into its component parts such that the activity of individual attackers is made clear.  By applying techniques from radar tracking, information warfare, and multisensor data fusion to info gathered from distributed IDS, we hope to improve the capabilities for early detection of distributed/coordinated attacks against infrastructure and the detection of the preliminary phases of distributed denial of service attacks.
    • Daniel Burroughs is a research engineer and Ph.D. candidate at the Institute for Security Technology Studies at Dartmouth College.  His areas of research have included mobile agents, distributed simulation, and distributed intrusion detection.  He is also the head of engineering for SignalQuest, Inc., which specializes in the development of embedded sensors.

  11. Ryan Lackey - Anonymous, Secure, Open Electronic Cash  (12.7M MP3)
    • Electronic cash has been the lynchpin of cypherpunk software goals for decades -- yet, there is no viable electronic cash system in the marketplace.  We will describe the theory, applications, past attempts, politics, failures, and successes in the field.  We present a specification and implementation of a new system which is secure, open, extensible, free, and which will hopefully avoid the technical and strategy mistakes which plagued earlier systems.  We will solicit developer involvement in creating applications which use this infrastructure.  We hope this infrastructure is a first step toward limiting the power of governments and other oppressors vs. individuals and small groups throughout the world.  It is also an example of how to proivide a critical infrastructure application, in an open-source form, in the post-dotcom world, and a generally-applicable demonstration of how security hardware and software can be used in applications to win user trust.
    • Ryan Lackey, founder and CTO of HavenCo, has been involved with electronic cash and other cypherpunk applications for years.  In addition to HavenCo and living full-time on Sealand, he works on several open-source software and hardware projects which are finally ready for public launch.  He has a great interest in seeing technology deployed in the service of individuals fighting against the State.

  12. Ian Peters - Rubicon: An Extensible Gateway IDS  (5.3M MP3)
    • IDSs have traditionally been seen as purely information resources, requiring human intervention in order to act on alerts.  Recently, support for modifying firewall rules and killing active connections have begun to appear in IDSs, but these suffer from shortcomings.  A desire has been recently expressed by many people for an active, 'Gateway' IDS (GIDS), allowing filtering and routing of traffic to be performed by a gateway computer using both traditional firewall-style rules, and also NIDS-style analysis.  Rubicon was developed to supply this functionality, and more, in an extensible manner.  This talk will discuss some shortcomings of current NIDS products, and hence the need for GIDS, the design and development of Rubicon, and the future for GIDS in general and Rubicon in particular.

  14. Roger Dingledine - The Mixminion Anonymous Remailer Protocol  (12.0M MP3)
    • Mixminion is a message-based anonymous remailer protocol intended to take the place of the old Mixmaster network.  Mixminion provides secure single-use reply blocks (Mixmaster provides no support for replies, instead relying on the older and less secure Cypherpunk remailers), and introduces nymservers that allow users to maintain long-term pseudonyms using single-use reply blocks as a primitive.  It also integrates directory servers that allow users to learn public keys and performance statistics of participating remailers.  I'll cover a variety of serious anonymity issues with Mixmaster and other deployed networks and published designs, and also describe some of the many surprising anonymity risks that come from adding these new services.
    • As a cryptographer and network security expert, Roger Dingledine lives in that space between theory and practice.  He prefers to tackle the really hard problems so one day we can build real solutions.  Current interests include anonymous publishing and communication systems, censorship-resistance, attack-resistance for decentralized networks, and reputation.

  15. Jaeson Schultz & Lawrence Baldwin - Extreme IP Backtracking  (9.0M MP3)
    • A prudent system administrator will review system logs.  While performing this log analysis, administrators may detect nefarious activity of various types (port probes, exploit attempts, DOS/DDOS).  Of course, what you receive in the system logs doesn't contain the offender's name and telephone number.  Rather, most firewalls and intrusion detection systems will log an IP address, or at best, a reverse DNS lookup of the IP address.  This presentation outlines several "Road-Tested" techniques for tracing IP addresses back to a responsible party.  Included are many real-world examples from our research; Step-by-step traces ranging from the trivial to the impossible.
    • Jaeson Schultz is an independent security consultant specializing in log analysis and intrusion detection.  He has accumulated over 14 years experience programming and troubleshooting networks for various governmental and corporate organizations.  Formerly employed by Counterpane Internet Security, Jaeson spent the last two years monitoring the security of Fortune 1000 companies and performing security and software engineering.  While at Counterpane, Jaeson helped to identify the networks responsible for the thousands of alerts received at the Counterpane Secure Operations Center per day.
    • Lawrence Baldwin is an independent Network Performance Consultant and author with over 15 years experience in deep protocol analysis and troubleshooting mission-critical networks and applications for Fortune 500 companies.  In 2000, Baldwin developed and deployed one of the first Internet "neighborhood watch" systems known as myNetWatchman (mNW).  mNW is a distributed IDS (dIDS) that uses the collective awareness of thousands of cooperating participants to identify compromised hosts and notify compromised machine owners.  In an average day, mNW processes more than 1,000,000 events from a global sensor network of more than 1,300 firewall and IDS systems in 40 countries.  mNW analyzes and back traces event activity from 50,000 unique hosts per day, identifying compromised hosts and sending Email notifications at a rate of approximately one per minute.  The data collected by mNW enables analysis of global attack trends, identification of DDoS bot assimilation activities, and signature-independent detection of new worm activity.

  17. Christian Grothoff - GNUNet  (12.0M MP3)
    • GNUNet is an anonymous peer-to-peer networking infrastructure.  GNUnet provides anonymity, confidentiality, deniability and accountability, goals that were thought to be mutually exclusive.  In GNUnet, users can search for files without revealing the query to anybody.  Intermediaries can not decrypt the query or the reply, but they can verify that the reply is a valid answer for the query.  This allows GNUnet to deploy a trust-based accounting scheme that does not require end-to-end knowledge about transactions and that is used to limit the impact of flooding attacks.
    • Anonymity in GNUnet is based on the idea that it a host is anonymous if the perceived sender of the message looks sufficiently like a router.  Based on this realization, GNUnet nodes can individually trade-off anonymity for efficiency without affecting the anonymity of other participants.  GNUnet is written in C and licensed under the GNU Public License.  GNUnet is officially part of the GNU project.
    • Christian Grothoff is a Ph.D. Student in Computer Sciences at Purdue University.  He is primarily working on OVM, a DARPA funded project to build a customizable real-time Java Virtual Machine.  Christian Grothoff started the GNUnet project, a secure peer-to-peer file-sharing network to protect privacy.

    • This presentation focuses on the ease with which many web application Session IDs can be brute-forced, allowing an attacker to hijack a legitimate web user's online session (e.g. Slashdot, Apache,, PHPNuke, etc.).  While a somewhat narrow area of web application security, the simplicity of the attacks and the prevalence of these vulnerabilities on the Internet make this an important topic.  Malicious users can easily try (usually automated) combinations of well-known usernames and passwords, or indeed attempt all possible combinations of the accepted Session ID character set.  However, the scope of a brute force attack can be greatly reduced when Session IDs are predictable in nature.  The presentation will include an overview of the issues involved in exploiting predictable or "reverse-engineerable" Session IDs in popular web applications, including a demonstration with several real-world exploitation examples.  It will conclude with a description of techniques both users and web developers can use to protect against these types of attacks.

    • Communication under TCP/IP networks has become extraordinarily popular; still, there remains significant problems that as of yet have remained unsolved within its layered rules.  So, lets break the rules, elegance (and possibly security) be damned.  Signficant new techniques and code will be unveiled to answer the following questions:
      • A)  Instant Portscan - Is it possible to discover instantaneously what network services have been made available, even on massive networks?
      • B)  Guerrila Multicast - Is it possible to send a single packet to multiple recipients, using today's multicast-free Internet?
      • C)  "NATless NAT" - Is it possible to share a globally addressable IP address without translating private IP ranges a la NAT?  Is it possible to allow incoming connections to an IP multiplexed in this manner?
      • D)  NAT Deadlock Resolution - Is it possible to establish a TCP connection between two hosts, both behind NATs?
    • Various interesting uses of these new packet-level primitives should be discussed, and OpenSSH will trotted out as the method of bringing some degree of security unto the resulting chaos.

  61. hellNbak - Selling Out For Fun and Profit - Part 1  (2.9M MP3)
    • Part 2  (1.8M MP3)
    • Recent events in the security industry have caused multiple groups to cry foul and claim that many so called hackers have sold out.  A war of words has errupted between those crying foul and those who have apparently sold out.  Most recently, Gweeds presented a talk at H2K2 that touched on many nerves when he pointed fingers at specific people in the security industry.
    • While the talk given by Gweeds was based mostly on made up stories and FUD, he touched on some points that deserve a bit of attention.  Additionally, the articles written in The Register by Thomas Greene points out that the media in general has a responsibility to verify facts - somthing does not seem to be hapenning.
    • The talk presented by hellNbak will address these issues along with some of the dirty little secrets in the security industry.  In general, hackers hack for the quest of knowledge and the ability to be places that others cannot go.  Based on this, Hacktivism, cyberterrorism, and selling out is a myth and until hackers are hacking for a real cause it always will be.
    • hellNbak has been around the IT security industry for 11 years and a member of NMRC for three of those years.  He has worked in a security related capacity for large companies such as IBM, BindView Development and Ernst & Young.  Up until this year, hellNbak has found it necessary to hide behind his NMRC nym but after DEFCON hellNbak, now a self-employed security consultant, no longer needs the cover of a nym to protect himself from clueless managers and threatening venduhs.

  1. Phil Zimmermann - A Conversation with Phil Zimmermann
    • Video  (39.7M RealMedia)
    • Philip R. Zimmermann is the creator of Pretty Good Privacy.  For that, he was the target of a three-year criminal investigation, because the government held that U.S. export restrictions for cryptographic software were violated when PGP spread all around the world following its 1991 publication as freeware.  Despite the lack of funding, the lack of any paid staff, the lack of a company to stand behind it, and despite government persecution, PGP nonetheless became the most widely used email encryption software in the world.  After the government dropped its case in early 1996, Zimmermann founded PGP Inc.  That company was acquired by Network Associates, Inc. (NAI) in December 1997, where he stayed on for three years as Senior Fellow.  In August 2002 PGP was acquired from NAI by a new company called PGP Corporation, where Zimmermann now serves as special advisor and consultant.  Zimmermann currently is consulting for a number of companies and industry organizations on matters cryptographic, and is also a Fellow at the Stanford Law School's Center for Internet and Society.

  2. Paul Wouters - Deploying DNSSEC

  3. Bruce Potter - Bluetooth - The Future of Wardriving
    • Video  (36.4M RealMedia)
    • By some estimates, there are more Bluetooth radios deployed than 802.11 radios.  However, Bluetooth as largely been ignored by the security community.  Over the next several years, this will change dramatically as Bluetooth security tools catch up with 802.11 security tools.  Bluetooth devices tend to be always-on machines that generally contain and transmit highly personalized information.  Due to limitations of the platforms and interfaces that utilize Bluetooth, many developers chose to avoid implementing security mechanisms.  This combination of private information and lowered security makes Bluetooth a likely candidate for attacks targeted at an individual... or simply an interesting protocol to keep voyeurs happy.  This talk will cover the basics of the Bluetooth protocol and its security mechanisms.  I will discuss attacks that may be carried out against Bluetooth enabled PANs.  I will compare Bluetooth and 802.11, especially from a discovery and interception point of view.  Finally, I will present The Shmoo Group's new Bluetooth wardriving utility.

  4. Leia Amidon, Omar Ahmed, David McLeod, Harry Regan - After Napster
    • Video  (37.2M RealMedia)
    • From Napster to the current emerging techno-social phenomena of livehives and smart mobs, the evolution of peer-to-peer networks is exhibiting an exponential profligacy both in use and popularity, and actually influencing the evolution of human social interaction on both a local and a global scale.  Beginning with Napster, the popular Internet file sharing software created in 1999 by Shawn Fanning, arguably a revolution has taken place.  Napster was at the forefront of the one of the most important electronic debates of the 20th century's fin-de-siecle: DMCA and various attendant copyright debates.  However, the perhaps the most important role that Napster played was as a "proof of concept" on a grand scale (98 million globally at its peak) of the power of peer-to-peer communications.  Wireless data communication devices have screamed onto the networking scene in and may be poised to revolutionize social intercourse.  Blogger journos can instantly upload text, audio, and video to their weblogs from the scene of breaking news events.  With conventional cellular telephones tactical organization of crowds, "smart mobs," can be coordinated in political actions.  The newest breed of communication technologies can document in real-time documentation of an event without the need to rely on traditional media reports.  In "proof of concept" exercises, recent anti-war protests have utilized "livehive" and "smart mob" technologies to out flank police actions and effectively shut down city centers and targeted economic targets.  "After Napster" will follow the evolution of peer-to-peer networks and their evolution as social communities of affording a new level of global awareness and action.

  11. J0hnny Long - Watching the Watchers: Target Exploitation via Public Search Engines
    • Video  (28.3M RealMedia)
    • In today's world of all-knowing, all-seeing search engines, it should come as no surprise that very sensitive information lies in the deep recesses of big search engines' data banks.  What may come as a surprise, however, is just how much of a search engine's collected data exposes security flaws and vulnerabilities about the crawled sites.  In some cases, even after a security hole is fixed, a search engine may cache data about that vulnerability, providing information about other avenues of attack.  This process of "watching the watchers" is not theoretical.  It happens, and it happens daily.
    • This session demonstrates the technique of crawling one of the most popular search engines for security vulnerabilities on one or many targets simultaneously.  Sample information will be extracted about various friendly targets without sending any data or packets to the intended targets, leaving those targets completely unawares.  A database of hundreds of vulnerabilities (and growing) will be uncovered and presented to the participants, as well as an automated tool which can be used to scan search engines for vulnerabilities on participant's hosts and networks.
    • A little-known research page has been started with working examples of this technique applied to one popular public search engine.  See for details.  This presentation (especially when presented in conjunction with a live Internet feed) is not only informative and eye-opening, but both refreshingly fun and amazing to watch.  Most participants will have a great deal of familiarity with the search engines presented and will be delighted (and rightfully concerned) to see them operating in a manner they were not designed for.  Solutions for remedying and controlling this amusing (yet very serious) vulnerability will also be discussed.

    • In this session, we will explore network fingerprinting through the use of high-frequency active probes to determine the network's delay.  We will also discuss how signal analysis techniques on those delay measurements can be employed to characterize a network's performance and configuration.  Using examples from a real-world enterprise network, various layer-1 and layer-2 features will be exposed including: a router or switch's queuing behavior, evidence of unrelated cross-traffic, and the presence of a configured monitoring or "span" port, perhaps indicating the presence of an eavesdropper.

  21. Bill Scannel - Punishing Collaborators Redux
    • Video  (28.6M RealMedia)
    • Just when you thought Total Information Awareness was dead, The Department of Homeland Security rolled out plans in February of this year to introduce an Orwellian airport passenger profiling system called CAPPS II.  The plan originally called for running checks on credit, banking, and criminal records every time a citizen flew on a commercial aircraft.  Bill Scannell didn't feel like being asked 'papers, please' every time he traveled, so he targeted the only airline participating in the testing of CAPPS II: Delta Airlines.  The resulting Delta boycott and millions of dollars in negative publicity caused Homeland Security to pull the plug on the program pending a privacy investigation, and for Congress to withhold all 2004 funding.

  22. Daniel C. Silverstein & Damon McCormick - Increasing the Security of Your Election by Fixing It
    • Video  (35.7M RealMedia)
    • In response to the problems that plagued the last United States presidential election, many communities plan to replace existing paper ballot machines with electronic voting systems.  Unfortunately, the new systems open up a Pandora's box of security issues that traditional paper ballots do not face.  It is difficult to understand the issues because there is a serious lack of data describing the real world performance of these systems.  This problem is compounded by the fact that the major commercial vendors' products are closed, proprietary systems protected as trade secrets.  Ignorance of the unique security concerns raised by electronic voting could leave U.S. State and Federal elections open to unprecedented levels of fraud.  This past April, a new online election system was used at the University of California at Berkeley.  We present this system as a case study, which sheds much needed light on electronic voting security.  We describe the workings of this system, and discuss the findings of our security analysis.  Additionally, we crafted a man-in-the-middle attack that exploits a flaw inherent in the system architecture.  Our talk provides a detailed technical explanation of the attack.
    • Finally, we discuss the implications of the case study.  We will show that many of our conclusions apply to the major commercial systems, in spite of tangible differences with the case study system.  We will answer questions from the audience, and offer constructive ways to address some of the concerns we raise.  This talk is suitable for attendees of all technical levels.  For a thorough understanding of our man-in-the-middle attack, we suggest that you have some programming experience and familiarity with DNS and NAT.

  25. Susan Brenner - Toward a Criminal Law for Cyberspace
    • Video  (35.7M RealMedia)
    • The traditional model of law enforcement was shaped by certain assumptions about criminal activity.  These assumptions derive from characteristics of real-world crime, i.e., that victim and offender must be in physical proximity, that crime is limited in scale, that physical evidence will be found at a crime scene and that crime falls into identifiable patterns.  These assumptions gave rise to a hierarchically-organized model which operates on the premise that crime is localized, i.e., occurs within a specific geographical area encompassed by a single set of national laws.  The traditional model, in effect, assumes the primacy of nation-states as law enforcers.
    • Neither these assumptions nor the premise that crime is localized apply to cybercrime; cybercrime makes nation-states irrelevant.  It evades the assumptions that shaped the traditional model and, in so doing, creates significant challenges for law enforcement.  It is therefore necessary to devise a new approach for dealing with cybercrime, one that takes into account the distinctive characteristics of technologically-mediated crime.
    • Such an approach is evolving in the cybercrime task forces established pursuant to a mandate contained in the USA PATRIOT Act.  Whereas the old model emphasized law enforcement's reacting to completed crime, this approach emphasizes collaboration between potential victims and law enforcement in an effort to prevent cybercime.  It also emphasizes lateral, networking arrangements in which law enforcement personnel often function more as consultants than as sole investigators.  Clearly, a lateral, collaborative approach is a more advantageous strategy for dealing with cybercrime.
    • The problem is that individuals also need to be involved if this approach is to be effective.  Currently, corporations and other entities are more likely to understand the need and have the resources to partner with law enforcement in an effort to implement cybersecurity.  This is not generally true of individuals, but it may be possible to use new principles of criminal liability - modified rules of criminal law and imported, modified civil law rules - to create incentives for individuals to participate in such an approach.

  31. Mikko Valimaki & Ville Oksanen - The Story of EFFI: How We Started a Cyber-rights Group in Finland, Which Kicks Ass
    • Video  (34.4M RealMedia)
    • We want to show you how just a couple of fellows can start a truly efficient cyber rights group at a regional level (state, country, etc.) and influence the encryption, privacy, fair use, etc. laws & change the public opinion.  We did this in Finland in a year.  EFFI was founded in 2001 and now, in summer 2003, has some 300-400 paid members and counting.  We got to the nation's main newspapers in spring 2002 and hit the radio and TV in fall 2002 and been since then regulars in the media.  Our top achievement so far has been stopping E.U. Copyright Directive (Europe's DMCA) in Finland.  We've also fundamentally changed the law on the feeedom of speech and spamming (see for details).
    • Next, we'll answer basic questions on how we get there.  Who proposes these laws and how can even individual hackers and tech enthusiasts influence the legislative process?  How did we build relationships to politicians?  How did we got ourselves to TV regulars in Finland and changedthe public opinion to our support?  How can we extend our regional success to European level?  Finally we want to explain why the political, moral, and legal issues are inherently global and why the hacker community should support action in every corner of the world.  We get into details of U.S. and European hacker-unfriendly politics and compare different options to support our common cause: influence parliamentary and democratic process vs. act independently & anonymously hacking the software of "evil corporations."  Our approach is to act with names and do everything politically correct.

  32. Silvio Cesare - Open-Source Kernel Auditing and Exploitation
    • Video  (38.6M RealMedia)
    • For a period of up to 3 months in 2002, a part-time manual security audit of the operating system kernels in Linux, FreeBSD, OpenBSD, and NetBSD was conducted.
    • The aims of audit were to examine the available source code, under the presumption of language implementation bugs.  Thus classic programming bugs, prevalent in the implementation language [C], exemplified in integer overflows, type casting, incorrect input validation and buffer overflows etc. were expected.  The initial introduction to auditing examined easily accessible entry points into the kernel including the file system and the device layer.  This continued to an increased coverage and scope of auditing.  From this work, identification of conjectured prevalent bug classes was possible.  These results are in favour of the initial expectations; that bugs would be that in line of classical language bugs.
    • The results of this audit are surprising; a large [more than naively expected] number of vulnerabilities were discovered.  A technical summary of these vulnerabilities will be treated in detail.  Bug classes and [conjectured] less secure specific subsystems in the kernel will be identified.  These conjectures support the the research of Dawson Engler's work in automated bug discovery in application to open-source kernel auditing.
    • Vulnerabilities after bug categorisation, are applied in the treatment of exploitation.  The results are again surprising; exploitation sometimes being trivial, and primarily being highly reliable.  The assumptions of exploitation difficulty, is conjectured to be a false belief due to lack of any serious focus on kernel auditing prior to this paper.  This conjecture is supported by in-line documentation of kernel sources indicative of immediate security flaws.
    • Attack vectors are identified as a generalisation of bug classes.  Risk management is touched upon to reduce the scope of attack, but is not the primary purpose of this paper.
    • Discussion is finally that of vendor contact, and the associated politics of vulnerabilities.  First hand reports of acknowledgement times, problem resolution times and public dissemination policies are presented in candid.  The author may be biased at this point, but it appears that in during this audit period, open-source holds up to the promise of security concern and responsibility in its community.  Problem acknowledgement in at least one of the the cases presented is perhaps the fastest in documented history (less than three minutes).
    • The majority of the vulnerabilities discovered during the audit, were resolved and patched in co-operation with the open-source developers and community responsible for each respective operating system.  A very large thanks must go to Alan Cox, Solar Designer and later followed by Dave Miller who made enormous efforts to continually resolve all issues uncovered.

  34. Richard Thieme - Hacker Generations: From Building the Network to Using the Network to Being the Network
    • It has all happened so fast.  Eleven years of Defcon define three identifiable generations of hackers.  (Yes, that's an arbitrary distinction, but it's useful.)  The first generation helped build the network, the second learned how to use the network, and the third has become the network.  The management of perception in the mind of society is the battle in which we are now engaged.  Online life is threaded through with deception and counter-deception, intelligence and counter-intelligence, but that's second nature to the latest generation of hackers.  They understand that intuitively.  They operate in small cells, manage their egos with discipline, and execute stealthy sophisticated operations with finesse.

  38. Seth Fogie - Embedded Reverse Engineering: Cracking Mobile Binaries
    • Video  (31.9M RealMedia)
    • The embedded mobile market is headed for a day of reckoning when it will become the target of virus/trojan writers.  To prepare for this, security experts must understand reverse-engineering fundamentals, as they apply to the pocket PC device, so they can research, investigate and understand the impact of malware and how to prevent it from spreading.
    • Unfortunately, when it comes to understanding malware for the PPC environment, there is little guidance.  The only exception to this is ironically found in the backyard of same people who would write the destructive code.  What we are talking about is the reverse-engineering of software protection schemes.
    • As a result, this talk will focus on the security protection schemes built into PocketPC software, and how these protections are circumvented.  Using the same tricks, tools, and techniques that crackers use to bypass anti-piracy schemes, we will demonstrate first hand how these programs are cracked using a simple 'crackme' serial validation program as an example.  We will start with a discussion on the hardware environment and reverse-engineering fundamentals to provide a background and foundation for the core of the talk; a step-by-step demonstration on how to crack a real program.

  40. Cindy Cohn - What Hackers Need to Know About Post 9/11 Legal Changes
    • Video  (40.1M RealMedia)
    • The Bush Administration's relentless assault on freedom and privacy online and offline hit the ground running with the PATRIOT Act in the immediate aftermath of 9/11, but hasn't slowed since then.  While the terrorist acts had absolutely no relationship to computer hacking, hackers were a clear target in the PATRIOT Act and subsequent developments.  The changes in the legal landscape are vast and wide, but anyone interested in computer security research, whether professionally or as a hobby, should have a basic understanding of the new world order.  EFF was one of the broad coalition of groups that fought the PATRIOT Act -- its analysis comes up first in a Google search on the law -- and continues its work opposing all of its ugly brothers, sisters, cousins and step-children.  The talk will focus on the portions of these laws and programs that affect hackers of all hat colors, including:
    • Changes in the Computer Fraud and Abuse Act; The expanded definitions of "terrorist" and "material assistance to terrorists" and what they may mean for toolmakers; All your logs are belong to us - the reduced provisions for subpoenas to ISPs and others who have information about you; What reduced judicial oversight,fewer checks and balances and more sharing among various cops means in practice; What Patriot II/DSEA holds in store; TIA, CAPPS II and other acronyms you should know about; How can you legally to better protect yourself and others.

  48. Michael Sutton & Pedram Amini - Hacking the Invisible Network: The Risks and Vulnerabilities Associated with Wireless Hotspots
    • Video  (35.2M RealMedia)
    • Wireless hotspots are emerging as an effective means of providing on-demand Internet access for users with 802.11x enabled devices.  The networks typically exist in places frequented by business travelers, such as hotels, airports or in locations with persistent clientele such as coffee shops.  The technology provides an efficient and cost effective way for companies to deliver Internet access to their customers and also offers an alternate revenue source, as many networks are "pay for play."  Most users are enticed by the convenience of these networks, but are unaware of the security risks that they present.  Companies have historically implemented security by building an impenetrable fortress around network assets.  This system is flawed.  It does nothing to protect the multitude of portable devices such as laptops and PDAs that are frequently used outside of this fortress.  Hotspots are shared networks that broadcast traffic.  By design, hotspots do not implement encryption schemes such as WEP, which provides a target rich environment for malicious attackers.  Unencrypted network traffic can be intercepted and traditional remote attacks can be perpetrated on machines that are operating without protection from attack.  This poses a significant risk for corporations as these devices commonly contain sensitive corporate data.
    • Research conducted on numerous hotspot implementations has revealed that most leave end users unnecessarily exposed to both local and remote attackers.  Most networks also have weak access controls that leave business owners exposed to loss of revenue from various attack scenarios such as session hijacking, data tunneling and connection sharing.  The presentation will address the following: The risks associated with using Hotspots.  Specific attack scenarios - identifying tools and techniques that were used.  The network design of specific hotspot implementations.  What users can do to protect themselves.

    • Your Unix-based webserver has logs, and you know you should be keeping an eye on them.  But what should you be looking for?  Would you recognize an attack even if you saw one?  What sort of automated log-watchers are available, and what if you need to tell *those* what to look for?  Attacking your own system while scanning its logs is a quick way to learn what anamolous log activity looks like.  Plus, it's a fun excuse to run Nessus, nmap, and whisker against someone who won't call the cops on you (i.e., yourself).  In my presentation I'll demonstrate this sort of productive self-abuse, using the aforemention tools plus less-glamorous but equally useful commands like telnet and wget.  My groovy two-laptop demos will show both attacks and logged messages simultaneously, adding to the overall excitement.  In addition to all that, I'll discuss how to fine-tune the mechanisms that control logging, and how to use automated log-watchers such as swatch (which needs to be told what to look for) and logwatch (which doesn't necessarily).  The presentation will culminate in a challenging game of "You Be the K1d10t," in which Defcon attendees will be welcomed to take their best shot at my wireless-connected laptop, while the audience & I watch the log messages that result (or don't).  Anybody who roots my box, or causes a really entertaining log message, will receive a piece of the donated junk arrayed on the stage for that purpose.  (But if my box gets DoSed beyond salvage, I'll just ask some trivia questions and call it a day, so please play nice!)  This will be a fairly technical presentation.  Attendees should have a working knowledge of the Unix variant of their choice (my demo systems both run Linux), but my presentation should be comprehensible to most Unix newbies, while still being useful to intermediate and maybe even advanced users (hey, everybody knows different stuff).

    • Video  (34.2M RealMedia)
    • As a corporate security advisor, former investigator, and TSCM technician, we will dispel the myths behing bugging and wiretapping.  We will separate what tappers can and can not do (everything you see in the movies is not always true!!).  What companies can do that will realistically protect themselves from eavesdropper and thereby help to protect their network, proprietary information, and intellectual property.  We will explain and demonstrate the sophisticated electronic tools used by a professional sweep team, and describe what happens during the sweep process.  We will demonstrate how phones are tapped in homes (analog phones), small businesses (KSU telephones systems), and larger companies (PBX systems).  We will show how corporate spies attempt to infiltrate company telephone systems and ultimately compromise your network infra-structure.  We show how anything purchased to detect eavesdropping from a "spy shop" will only waste your money and give you a false sense of security.  We lay out the planning and execution of a successful sweep, and explain how to protect your company from threats in the future.

  58. Viki Navratilova - Today's Modern Network Killing Robot
    • Video  (32.5M RealMedia)
    • Today's Modern Network Killing Robot will give an overview on the new generation of DDOS tools.  Back in the day, a couple of large pings could take down lots of machines.  When those techniques stopped being effective means of taking down networks, people started writing DDOS programs.  These programs required a little bit of manual work to install, but were effective at taking down large networks for a while.  This generation of DDOS tools were made famous in the media by DDOS'ing famous websites for hours at a time.  Soon people learned to control the damage done by these tools, and so a new generation of DDOS tools were born: Ones that could infect thousands of machines automatically to create large botnets, and hide their communications in order to evade detection better than their predecessors.  These botnets are now the most effective DDOS tools in popular use today.  This talk will go over the more popular botnets, such as gtbot and sdbot, and talk about how they work and some ways to spot them on your network.

  2. Peter D. Feaver and Kenneth Geers - The First International Cyber War: Computer Networks as a Battleground in the Middle East and Beyond  (4.5M MP3)
    • This briefing addresses the world's first global Internet war: the cyber skirmishes associated with the Palestinian intifadah.  What started out as a localized conflict spread to battles around the globe as forces sympathetic to either the Israelis or the Palestinians joined the fray.  With the Middle East cyber war as a backdrop, this presentation will cover the ways in which people can try to affect the course of world history through coordinated action in cyberspace.  The authors first describe the globalized and asymmetric nature of modern warfare, the asymmetry of computer hacking, and the psychology of subcultures.  They outline the legal issues surrounding cyber warfare, from the perspective of a lone hacker to a massive government intelligence service, and discuss the problems inherent in cyber retaliation and in the prosecution of hackers.  On the technical side, this briefing discusses the targeting of Internet sites for attack, and the strategies used by hackers to bring them down or merely leverage them in more subtle ways to support their cause.  The primary focus is the means used by cyber commanders to accomplish political and/or social goals, in particular the creation of Web portals through which their foot soldiers are able to unite and rain network packets down upon their enemies.  Finally, this briefing examines the difference between the perception and the reality of cyber attacks.  We address the strategies that national governments are employing to combat the threat, the potential impact of cyber attacks on military operations, and the vexing problem of Denial of Service attacks, Web defacements, and free speech.  The authors assess the threat and the limits of the more powerful weapons in the cyber arsenal, and consider who might be the biggest target of cyber attacks in the coming years.  Peter D. Feaver (Ph.D., Harvard, 1990) is Professor of Political Science and Public Policy at Duke University and Director of the Triangle Institute for Security Studies (TISS).  Feaver is co-directing (with Bruce Jentleson) a major research project funded by the Carnegie Corporation, "Wielding American Power: Managing Interventions after September 11."  Feaver is author most recently of Armed Servants: Agency, Oversight, and Civil-Military Relations (Harvard Press, 2003),and co-author, with Christopher Gelpi, of Choosing Your Battles: American Civil-Military Relations and the Use of Force (Princeton University Press, 2004).  He is co-editor, with Richard H.

    • Due to improper software design and implementation practices, the number of web-based applications vulnerable to SQL injection is still alarmingly high.  Yet the actual steps used to exploit these applications remain very tedious and repetitive.  This presentation will focus on methods available to automate the task of exploiting blind SQL injection holes.  It will also feature a new tool, "sQueaL" and explain some of the research, used in the creation of this tool as well as ideas for expansion on the tool or other uses of the core libraries developed.  Cameron Hotchkies, a.k.a. nummish, is a member of the digital think-tank and head developer of the new blind injection tool, SQueaL.  In his non-free time, he works as a web-application developer and has witnessed (and had to repair) great atrocities in web application design.  This has left him a bitter and frail shell of his former self.  Some people have suggested he get out more.  He is currently struggling to write code to teach him how to properly pronounce the word "about."  This will be his first time speaking at Defcon.

  9. Robert Imhoff-Dousharm and Jonathan Duncan - Credit Card Networks Revisted: Penitration in Real-Time  (21.6M MP3)
    • Credit card authorization is the core to all major businesses, both on and off the Internet.  Yet an alarming number of businesses are not taking the right steps to insure that your credit cards are secure against fraud and theft.  In bringing this to light (Credit Card Networks 101, July 31, 2003 - DC 11), you were awed at the posibility, but were not provided with any real proof.  This year we, that's you and I, will walk through the process of identifying credit card traffic on a network, decyfering packets and propagated rouge credit card data to a host comeputer.  You will be provided access to a private WiFi network.  This networks will have credit card data streamming across it for you to sniff.  With your help, we will discover information about credit cards packets, and how to design our own packet to be sent.  Robert "hackajar" Imhoff-Dousharm in the last 2 years, Robert has worked for Shift4, a Credit Transaction Gateway.  As an analyst he insures best fraud practices, compliceny and security are meet at all clients sites.  He has worked with government agency's during fraud investigations.  He also works with new and potential clients to implement best practice in software design of credit card intigration software.  Robert has spoken at DEFCON 11 (Credit Card Networks 101) about the potential risks currenly impeading on credit card networs.  He will demonstrate those risks this year with "Credit Card Networks Revisted: Penitration in Real-Time".

  11. Foofus - Old Tricks  (21.9M MP3)
    • In September of 2003, a noted security consultant was terminated from his job over controversy surrounding a document that he co-authored.  One key focus of the document was the risk associated with operating system monocultures.  This idea was nothing new.  In fact, in 1989, the following passages appeared in a book that spent over four months on the New York Times best seller list: "Just like genetic diversity, which prevents an epidemic from wiping out a whole species at once, diversity in software is a good thing.  A computer virus is specialized: a virus that works on an IBM PC cannot do anything to a Macintosh or a Unix computer.  [snip] Diversity, then, works against viruses.  If all the systems on the Arpanet ran Berkeley Unix, the virus would have disabled all fifty thousand of them.  Instead, it infected only a couple thousand." -- Stoll, Cliff.  The Cuckoo's Egg, New York: Simon and Schuster Pocket Books, 1989.  Pages 51 and 347.  The point of this citation is not to cast any disrespect on the authors of "CyberInsecurity: The Cost of Monopoly" (on the contrary, in fact).  Rather, we wish merely to note that the risk of monocultures was identified at least fourteen years ago, and was widely published.  Why fuss if someone repeats it? wants in on this kind of action.  In that spirit, we've looked high and low for a bunch of other old ideas so that we can breathe new life into them, and (in the famous words of a respected security research team), make "the theoretical practical," in an effort to tax the patience of those who would rather we kept our heads in the sand about ideas that are right there in the open, but inconvenient to demonstrate.  Until now.  Come to this presentation, and savor some exquisite fun.  We will demonstrate our tools and techniques, and we think you will find that they are interesting and useful.  But not new.  We promise that we have not invented a damn thing here; the basic concepts are 100% recycled, but we hope they will encourage people to get serious about areas where they've been coasting for too long.  The focus of the talk is Windows: tools will be presented for identifying potential trust relationships between disparate hosts, tinkering with friendly wireless interfaces, easy access to network shares without bothering to crack password hashes, and (if our luck holds) maybe even alittle more.  It'll be really fun, and stuff.  Foofus leads a team of security engineers at a midsize technology consulting firm in the midwest, where he has worked for the past seven years.  He has spoken at a variety of events and conferences including Toorcon and LISA.  His chief technical interest is software security, and in his spare time he enjoys playing guitar, cooking, and attending the symphony.

  12. Rakan El-Khalil - Information Hiding in Executable Binaries  (20.1M MP3)
    • Information Hiding (IH) techniques are much researched in the context of watermarking or fingerprinting images and sound files, mainly as a means of copyright protection and piracy prevention/detection.  Those mediums offer a significant amount of redundancy, thus lending themselves to the implementation of robust IH systems.  Executables however do not offer such amounts of redundancy, and have thus far proven to be a difficult and rarely used medium for steganographic and other IH purposes.  The aim of this talk is to be an introduction to IH, with a thorough coverage of state of the art techniques for embedding into binaries.  Hydan, a tool for performing such embeddings in machine code, will be presented.  In addition to typical IH uses [steganography, watermarking], the tool and techniques shown can be used in anti-reverse engineering, trusted application execution, frustrate some buffer overflow attacks, and as an engine for metamorphic viruses.  An interesting effect of the tool is that the executable remains the same size before and after embedding, while of course remaining functionally equivalent.  Rakan El-Khalil is currently on sabbatical in France.  He is a recent MS CS graduate from Columbia University.  While he was there he worked on a variety of projects at the CS Research Lab, such as an IDS that uses machine-learned models to detect network threats, and a syscall based permission system on OpenBSD [predating systrace].  He was also responsible for the short-lived official KaZaA Linux client `kza'.  Currently he is involved with The Bastard, a powerful linux disassembler, and has been researching steganography and information hiding in machine code.

  13. Michael Davis - The Open-Source Security Myth and How to Make it a Reality  (24.3M MP3)
    • Open Source software is frequently described as more secure, than closed source software for two reasons: the number of people available to correct a problem is potentially larger; and anyone can review the source code for vulnerabilities or malicious code.  Unfortunately, the current state of design documentation does not support a cost-effective security review.  In addition to compromising the confidence in the software, the lack of documentation also sets an unnecessarily high bar, for new members to join an Open Source projects.  This unintended consequence directly reduces the number of people available to correct vulnerabilities or otherwise improve the software.  The presentation provides a rationale for creating development documentation and identifies available tools.  Michael Davis oversees the Security Engineering services provided by Dynamic Security Concepts, Incorporated (DSCI).  During recent efforts to encourage his customers to use Open Source solutions; he oversaw the security review of a number of Open Source security tools.  He possesses a broad security background and has been a featured speaker for select audiences on the subject of intrusion detection and evaluating security solutions in general.

  14. Deral Heiland - The Insecure Workstation  (20.6M MP3)
    • The insecure workstation.  A creative look at the windows group policies as a security solution in today's workplace and how easily they are circumvented.  This talk will discuss the where, what and why on policies and also demonstrate simple tricks to bypass policies and exploiting poor policy implementation.  Deral Heiland has been in the IT field since 1994 working in the following industries; newspaper media, system integrator, manufacturing.  Held the following position network administrator, financial systems manager, network field engineer and network security analyst.  He presently holds the following certifications SSCP, CCNA, CCWS, CNE5 and CWSE.

  15. Maximillian Dornseif - Far More Than You Ever Wanted to Tell - Hidden Data in Document Formats  (24.6M MP3)
    • Applications usually put all kinds of information besides the ones which you intend to into saved documents.  This can lead to embarrassing revelations.  We will take a look into different types of application data and what can be hidden in there.  This allows us to "scrub" our own documents to avoid unwanted information in there but also to look for information in documents which the authors didn't want to hand out.  Go grasp the scope of the problem we will present a large scale study of hidden information in documents on the Internet.  Maximillian Dornseif has studied laws and computer science at the University of Bonn, Germany where he wrote his PhD thesis about the "Phenomenology of Cybercrime."  He has been doing security consulting since the mid-nineties.  His clients included the industry but also government.  At the moment he works on a third party founded research project about measurement of security and security breaches taking place at the Laboratory for Dependable Distributed Systems, RWTH Aachen University.  He also oversees several other projects in the area of detection and documentation of security incidents.  Dornseif has published in the legal and computer science fields on a wide range of topics.

  16. Brett Neilson - The Advantages of Being an Amateur  (24.9M MP3)
    • For close to 100 years amateurs have been working with radios and sending transmission all over the world.  The dawn of the information age has inspired many new technologies and advancements in communication; and amateur radio is no exception.  Today's modern amateur radio operators are building wireless networks and enjoying several advantages over their unlicensed counterparts.  This presentation will review some of these advantages as well as talk about some of the newer areas of interest including HSMM and APRS.  Brett L. Neilson is a network security and systems engineer with a strong background in the wireless industry.  Currently he is working for one of the world leaders in intrusion prevention supporting clients with network security related issues.  He previously worked for one of the leading wireless communication companies as a Senior Systems Administrator and RF field technician.  While there he worked to develop, deploy, and maintain their national infrastructure.  Some of his work is currently published in two information security related books, Maximum Wireless Security and Maximum Security 4th Edition.  Mr. Neilson is a former member of the North Texas FBI Emergency Response Team (InfraGard) and is a FCC-licensed amateur radio operator.  In these roles he has worked with multiple government agencies providing emergency communication assistance and coordination.  Mr. Neilson's broad knowledge and experience has allowed him to be involved with many organizations; providing network and security related solutions.

  17. J0hnny Long - Google Hacking- The Return of the Googledorks  (24.9M MP3)
    • Google hacking is not new, but it's back and deadlier than ever.  This talk is the follow-up to last years very successful talk "Watching the Watchers."  Attendees will learn the tricks and tactics that any self-respecting Google hacker should know.  Expanded extensively since last year, the techniques and always killer examples from the "googledorks" database are always a crowd-pleaser.  Witness how sites from all over the net fall victim to seemingly impossible searches from hackers armed with only the world's hottest search engine.  A special 'security' section this year covers how to find everything from usernames and passwords to live IDS data, live vulnerability scanner output and SQL injection points.  This talk intends to spread the word and help protect the security community from this dangerous and eye-opening form of information leakage.  Johnny Long "sold out" many years ago by accepting an I.T. position within a major international company.  By promptly securing each and every site he breaks into, Johnny has managed to maintain his friendships with hackers on both sides of the security fence.  Regardless of the color of his hat, Johnny is still passionate about hacking, and it shows through his work, his website and especially through his presentations which consistantly secure rave reviews.

  19. Wavyhill and Andre Goldman - Toward a Private Digital Economy (Trusted Transactions In An Anonymous World)  (25.9M MP3)
    • Current financial privacy tools have drawbacks arising from centralized ownership and control, and the limitations of the service-for-profit model.  A better approach is to construct a fully distributed environment for economic activity which mimics in freedom and variety of action the way cash is used in the physical world.  The key to this variety is the element of locale.  We introduce the "Farmer's Market" model of anonymous commerce and refine it to a software functional description.  We explore some exotic kinds of business viable in this new environment and ways to connect them to the transparent banking world.  Number theory can be used to derive an "algebra of trust," exploited in practical ways to reduce risk in anonymous transactions, and overcome barriers to adoption of this and other digital cash systems.  We also discuss the boot-strapping problem and suggest some ways to address it.  Afterward, everyone is invited to participate in a role-playing simulation experiment to test the viability of these ideas using a prototype graphical software environment.  Wavyhill is a software engineer having a 25 year history with industrial research organizations and developers of operating system, video, and graphics products.  An anarcho-capitalist without portfolio and advocate of privacy and anonymity, he has also done experimental engineering work on artificial islands.  He has no academic credentials that he will admit to.  Andre Goldman writes on law and philosophy.  He works in the area of non-jurisdictional law, and was the primary author of "The Common Economic Protocols."

  20. Greg Conti - Network Attack Visualization  (24.1M MP3)
    • On even a moderately sized network, activity can easily reach the order of millions, perhaps billions, of packets.  Hidden in this sea of data is malicious activity.  Current network analysis and monitoring tools primarily use text and simple charting to present information.  These methods, while effective in some circumstances, can overwhelm the analyst with too much, or the wrong type of, information.  This situation is worsened by today's algorithmic intrusion detection systems, which, although generally effective, can overwhelm the analyst with unacceptably high false positive and false negative rates.  This talk explores the possibilities of visually presenting network traffic in a way that complements existing text-based analysis tools and intrusion detection systems.  By graphically presenting information in the right way, we can tap into the high-bandwidth capability and visual recognition power of the human mind.  Using the proper visualizations, previously masked anomalous activity can become readily apparent.  This talk will be of interest to those who wish to learn about information visualization as it applies to network security.  It requires a basic understanding of the OSI model and packet encapsulation.  Attendees will leave with an increased understanding of information visualization that they can apply to their own development projects and management of their networks.  Greg Conti is an assistant professor of computer science at the United States Military Academy.  He holds a masters degree in computer science from Johns Hopkins University and a bachelor of science in computer science from the United States Military Academy.  His areas of expertise include network security, interface design and information warfare.  Greg has worked at a variety of military intelligence assignments specializing in signals intelligence.  Currently he is on a Department of Defense fellowship and is working on his PhD in computer science at Georgia Tech.  He is conducting research into denial of information attacks.

  21. Lucky225 - Phreaking in the Age of Voice Over IP  (13.9M MP3)
    • Phreaking in the age of voice over IP?  What the hell is voice over IP?  If you're asking this question and you're interested in phones and thought phreaking was dead back in the early '80s when blueboxing died, or 2002 when AT&T killed redboxing on long distance calls then, this is the speech for you.  Or if you know what VoIP is but want to know how the hell it has any impact on phreaking you should also attend.  This talk intends to educate it's audience on the new age phreakers.  Most of the discussion will involve a detailed explanation of Calling Party Number (CPN), ANI, and Caller ID, and the differences between all three, we will also be covering the basics of phreaking with voice over IP technology, Asterisk, and VXML.  Not all of this presentation will be dealing with VoIP, this is a basic new age phreaking presentation that will show the latest techniques that phreaks are using today it's not just about free calls either, hell you get that with VoIP anyways!  You will learn not only why VoIP is important, but such things as spoofing caller ID (and no we don't mean orangeboxing, social engineering telus, our methods are simple to use and will cost as little as $15/month).  As technology is rapidly changing, so is our phone system.  We will be discussing a basic over view of voice over IP and some of the services provided by many of these so-called "broadband phone companies."  We will also be discussing calling cards that use VoIP technology to provide cheaper rates to their customers.  We intend to explain how VoIP is changing the phone system and making it very easy for the every day consumer to spoof caller ID by spoofing Calling Party Number (CPN), and how this can be exploited to circumvent security in such things as voicemail, credit card activations, and even telephone company numbers that when you call from your "own phone" will give you complete control over your dial-tone telephone line.  We also plan on showing how easy it is to get around services like "Call Intercept" without even spoofing caller ID.  We will also be discussing why *67 and complete caller ID block features offered from the phone company are not adequate privacy protection as anyone can still get your phone number when you call them with your number blocked, we'll of course describe how this can be possible.  As time permits there may very well be much more, you wont want to miss this presentation.  Lucky225 is the co-host of an Internet streaming radio show "Default Radio" that streams on Rant Radio a free non-profit shoutcast server that has been running for 6 years.  He has been a writer for 2600 magazine since 1999 and has spoken at both H2K2 and DEFCON 11.  He has been an avid phone phreak since his early teens in high school and has much experience with the telephone system and a wide variety of knowledge ranging from regular telephones, payphones, cell phones, and voicemail systems to ANI, caller ID, PBX's, switches, VoIP and much more.  Strom Carlson is one of the last true phone phreaks; he has an intense interest in the structure and history of the telephone network and an intense distaste for fraud, theft, and vandalism.  He collects all things related to telephony (including recordings), and although he is rapidly running out of space in which to store his many cubic meters of telephone equipment, he will eagerly and compulsively snap up anything made or published by Western Electric if given the chance.  He encourages all phone phreaks and interested parties to learn what they're really talking about; he also encourages you to listen to everything on and to poke around

  22. Tony Arcieri - PDTP: The Peer Distributed Transfer Protocol  (18.7M MP3)
    • Despite decades of evolution, Internet file transfer is still plagued with problems to which formalized solutions are either inadequate or nonexistent.  Lack of server-side bandwidth often renders high demand content inaccessible (which we affectionately refer to as the Slashdot effect).  When the ability of a single server to provide content is exceeded, manual mirror selection is often utilized, providing an unnecessary and often problematic experience for end users.  No formalized cryptographic mechanism exists for preventing tampering of files located on a particular server, and consequently malicious individuals have managed to place Trojans in the releases of many high profile open source applications.  The Peer Distributed Transfer Protocol (PDTP) aims to solve all these problems.  PDTP can either function with a network of servers providing content directly to clients, or can provide BitTorrent-like download swarming, by forcing clients to participate in file transfers.  PDTP includes built-in mechanisms to prevent file tampering through the use of the Digital Signature Standard, and is able to automatically verify that a given file has been signed by a DSA key with a complete x.509 certificate check to ensure a given certificate can be trusted.  PDTP also provides a UDP-based decentralized search mechanism which, unlike current systems such as FastTrack, Gnutella, or FreeNet, does not consume undue bandwidth or system resources, all while removing legal liability for content indexing from the central services being utilized as entry points to the search system.  Tony Arcieri is a system administrator and programmer for the Pielke Research Group and Colorado Climate Center at Colorado State University.  He has also contributed to a number of open source projects, including authoring the Ogg Vorbis plugin for XMMS, the cdcd and gdcd X11 CD player applications, and various contributions to other projects such as the subversion version control system and the FreeBSD operating system.

  23. Wendy Seltzer and Seth Schoen - Hacking the Spectrum: Open Source Software Vs. the Broadcast Flag  (23.0M MP3)
    • The FCC, at Hollywood's request, has mandated a broadcast flag for High-Definition Digital Television (HDTV).  By July 2005, it will be unlawful to sell devices that don't respond to a "do not copy" flag or that provide unencumbered high-definition digital outputs.  The flag's "robustness" requirement will make it impossible to build an open-source HDTV version of the TiVo.  This talk will demonstrate how these rules thwart user innovation, showing an open-source HDTV PVR (MythTV on Linux) you soon won't be able to build.  We'll discuss the law and challenges to receiver regulation, and encourage people to get HDTV cards while they still can. Wendy Seltzer, Electronic Frontier Foundation Staff Attorney.  Wendy Seltzer is a staff attorney with the Electronic Frontier Foundation, specializing in intellectual property and free speech issues.  As a fellow with Harvard's Berkman Center for Internet and Society, Wendy founded and leads the Chilling Effects Clearinghouse, helping Internet users to understand their rights in response to cease-and-desist threats.  Prior to joining EFF, Wendy taught Internet law as an adjunct professor at St. John's University School of Law and practiced intellectual property and technology litigation with Kramer Levin Naftalis and Frankel in New York.  Wendy speaks frequently on copyright, trademark, open source, and the public interest online.  She has an A.B. from Harvard College and J.D. from Harvard Law School, and occasionally takes a break from legal code to program (Perl).  Seth Schoen, Electronic Frontier Foundation staff technologist.  Seth Schoen created the position of EFF staff technologist, helping other technologists understand the civil liberties implications of their work, EFF staff better understand the underlying technology related to EFF's legal work, and the public understand what the technology products they use really do.  Schoen comes to EFF from Linuxcare, where he worked for two years as a senior consultant.  While at Linuxcare, Schoen helped create the Linuxcare Bootable Business Card CD-ROM.  Prior to Linuxcare, Schoen worked at AtreNet, the National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory, and Toronto Dominion Bank.  Schoen attended the University of California at Berkeley with a Chancellor's Scholarship.

  24. Dan Kaminsky - Black Ops of TCP/IP 2004  (26.8M MP3)
    • Continuing the research done in previous years on advanced protocol manipulation and the high speed evaluation of large network characteristics, this year's Black Ops of TCP/IP goes into new territory with a deep analysis of the Domain Name System (DNS).  A core element of the TCP/IP application suite, it is everywhere and there is unexpected power contained within.  Interesting Facets of the Global DNS Architecture: A high speed scanner for DNS servers, modeled after my TCP scanner "scanrand," recently executed several Internet-scale sweeps of the net.  Surprising results, with direct implications for computer forensics operations, will be discussed and analyzed.  Distributed, High Speed, Large File Dissemination via DNS, a.k.a. "Reinventing the Square Wheel."  Although there have been previous attempts to serve files over the DNS architecture, none have been even remotely usable.  I will discuss a new approach that, through its significant performance improvement, is indeed remotely usable.  One-To-Many Streaming Data Dissemination over DNS: The previous system maximizes speed at the expense of making streaming impossible.  We will discuss an interesting alternate approach that almost usefully distributes streaming audio data to endpoints via their DNS queries.  SSH over DNS: I will demonstrate a cross-platform, userspace mechanism for moving SSH data over DNS queries.  This has implications for captive wireless portals, which often allow bidirectional DNS traffic.  To complete this work, some enormously complex data needed to be understood, and tools were worked with and written towards that end.  Experimental 3D information visualization mechanisms and tools are thus available to be demonstrated, extending from using a 3D renderer usually used for MRI medical data as a generic static 3D canvas to using a custom OpenGL particle plotter to dynamically plot multidimensional factors of incoming data streams.  A number of other topics will be raised as well, including:  Uses and abuses of remotely visible incrementers and decrementers (such as the IPID field in many TCP/IP stacks, and initial TTL values on arbitrary DNS queries).  Uses of generic packet race conditions, whereby useful information can be gleaned from which packet of a relatively large set effects the state change.  Protocol transliteration between TCP and UDP, allowing unreliable communication over what appears to be a TCP session, and allowing reliable data to be transmitted, with zero data expansion, over a UDP link.  Potential solutions to the SSH bastion host security problem, whereby the invocation of remote ssh binaries at a firewall or "bastion host" opens up a single point of major failure for a server infrastructure.  Dan Kaminsky, also known as Effugas, is a Senior Security Consultant for Avaya's Enterprise Security Practice, where he works on large-scale security infrastructure.  Dan's experience includes two years at Cisco Systems designing security infrastructure for large-scale network monitoring systems, and he is best known for his work on the ultra-fast port scanner scanrand, part of the "Paketto Keiretsu," a collection of tools that use new and unusual strategies for manipulating TCP/IP networks.  He authored the "Spoofing and Tunneling" chapters for "Hack Proofing Your Network: Second Edition", and has delivered presentations at several major industry conferences, including Linuxworld, Defcon, and past Black Hat Briefings.  Dan was responsible for the dynamic forwarding patch to OpenSSH, integrating the majority of VPN-style functionality into the widely deployed cryptographic toolkit.  Finally, he founded the cross-disciplinary DoxPara Research in 1997, seeking to integrate psychological and technological theory to create more effective systems for non-ideal but very real environments in the field.  Dan is based in Silicon Valley.

  25. Nathan Hamiel - Down With the RIAA: Musicians Against the Recording Industry  (21.7M MP3)
    • Down with the RIAA is a look at the current state of the music business and where it is headed.  The presentation uses statistics and facts to map out where the industry currently is and details the problems with the current model.  After the problems with the current model are shown then the groundwork for the future of the music business is laid out showing how the recording industry is no longer needed.  Included in the presentation is information on how artists can produce their own music cutting out the recording business.  The recent increase in quality and decrease in price of recording equipment has made it very feasible for artists to make very high quality recordings on their own.  This is the way of the future, and the processes are detailed by an independent music producer with experience in the field.  Most people do not know it is possible to make quality recordings that rival commercial ones from your apartment, without even disturbing your neighbors.  People are screaming for a change in the music industry.  With all of the problems that the RIAA is creating for the music consumer, consumers will begin to be open to a new model where the hassles of the RIAA will no longer be an issue.  The future of the music business will also afford more opportunity to artists leveling the playing field and decreasing competition between artists.  Nathan Hamiel (Ichabod Ver7) is an independent artist and producer living in Jacksonville, FL.  As an artist he has shared the stage with acts such as The Union Underground, Fuel, Scrape, 8Stops7, Phoenix TX, The Crux Shadows, and many more.  Using his skills gained as a recording engineer he has been able to create high quality recordings using very reasonably priced equipment many times surpassing the quality of commercial recordings.  He has many albums and recordings to his credit and shares the knowledge with other artists and producers world wide.  He has created some of his own techniques, including ones on layering drum samples that can now be heard on many different recordings.  On the technology side, he is a CISSP, was a presenter at Interz0ne 3, and VP of the Jacksonville 2600.

  26. Grifter, Russ Rogers and Tierra - Project Prometheus  (24.0M MP3)
    • The goal of Prometheus is to create an open source project that takes into account the inherent flaws in the Microsoft implementation of Alternate Data Streams (ADS) and uses those attributes to create a tool for increased security.  The concept is similar to making lemonade from lemons.  We're taking an insecure component of the NTFS file system and creating a tool that will provide increased security.  Russ and Grifter will be explaining and demonstrating the use of Alternate Data Streams and then discussing an open source project which they have currently begun development on.  Grifter has been involved in the scene for over a decade and currently runs 2600SLC, the Salt Lake City 2600 meeting, and DC801 the Utah Defcon meeting; where he often lectures on a range of security related topics.  He has been published in numerous online and print publications and has previously been a speaker at several Defcons.  He has also been the subject of interviews for various online, print, and television pieces regarding different areas of the hacker culture over the years.  He is a Defcon goon and primary organizer of the Defcon Scavenger Hunt and Defcon Movie Channel.  Russ Rogers is the CEO and CTO of Security Horizon, a Colorado Springs based information security professional services firm and is a technology veteran with over 12 years of technology and information security experience.  He has served in multiple technical and management information security positions that include manager of professional services, manager security support, senior security consultant and Unix systems administrator.  Mr. Rogers is a United States Air Force Veteran and has supported the National Security Agency and the Defense Information Systems Agency in both a military and contractor role.  Russ is also an Arabic Linguist.  He is a certified instructor for the National Security Agency's INFOSEC Assessment Methodology (IAM).  Tierra, while still somewhat new to the scene, has been manipulating bits since the 7th grade, and is currently working on his computer science degree at the University of Utah.  He has been attending 2600 meetings for more than 3 years now in Salt Lake City, and has been helping run the Defcon Scavenger Hunt since DEFCON 10 (you'll find him at the scavenger hunt table again this year).  While working with the DC801 crew on projects such as this, he spends his time mastering his PHP and SQL skills on various personal projects such as TIMAP found on SourceForge.

  27. IcE tRe - Virus, Worms and Trojans: Where are we Going?  (14.7M MP3)
    • It seems that the major target of most online bugs is actually quite the same.  Over and over again the uninspired, pop the box, seems to be what most writers are after.  In this talk I will explore a bit of virus history in relation to goals, starting with older viral intentions, moving to what appears to be the intentions today and what possibly could be the intentions tomorrow.  This talk will be fairly abstract and I will setup the examples that I use so no previous knowledge will be needed other than a basic idea of how viruses work and what damage they can cause.  This information, most people already have from the coverage gleaned from your average newscast, if not other places.  This talk in particular, should appeal to the broadest audience.  IcE tRe, like many of the people attending Defcon has been involved with networking/internet/"new media" since the early 90's.  Working with two major unnamed ISP over the years has helped these companies weather the storm of the past 10 years of viruses, DDOS attacks and various other security problems.

  28. Michael Rash - Advanced Netfilter; Content Replacement and Port Knocking Based on Passive OS Fingerprinting  (24.8M MP3)
    • The boundaries between network access control devices and network monitoring devices are steadily becomming blured.  Network intrusion detection systems are moving into the realm of not only monitoring network traffic, but also modifying it either through dynamic reconfiguration of firewall rulesets, spoofed session-busting traffic, or outright alteration of application layer data (ala Snort_inline).  Firewalls themselves are also getting smarter about protocol validation and application layer data.  This talk will discuss two main topics; 1) a patch to the 'iptables' string match extension in the Linux kernel that allows iptables to perform the same data substitution as Snort_inline but three times faster, and 2) a new tool called "fwknop" that implements port knocking authentication based on passive operating system fingerprints as detected via iptables log messages.  The latter makes it possible to allow only, say, Linux systems to connect to your SSH daemon.  Michael Rash holds a Master's Degree in applied mathematics with a concentration in computer security from the University of Maryland.  Mr. Rash works as a security research engineer for Enterasys, Inc. where he develops signatures and writes code for the Dragon IDS.  Previous to Enterasys, Michael developed a custom host-based intrusion detection system for USinternetworking, Inc. which was deployed on over one thousand systems from Linux to Cisco IOS.  Michael frequently contributes to open source projects such as Netfilter and Bastille-Linux, and has written security related articles for the Linux Journal, Sys Admin Magazine, and Information Security Magazine.  He is also a co-author of the book "Snort-2.1 Intrusion Detection" published by Syngress (to be published in late May, 2004).  Michael is the developer of two open source tools "psad" and "fwsnort" that are designed to tear down the boundaries between iptables and the Snort IDS.  More information about Michael and his open source projects can be found at:

  32. Elonka Dunin - Kryptos and the Cracking of the Cyrillic Projector Cipher  (24.2M MP3)
    • In a courtyard at CIA Headquarters stands an encrypted sculpture called Kryptos.  Its thousands of characters contain encoded messages, three of which have been solved.  The fourth part, 97 or 98 characters at the very bottom, have withstood cryptanalysis for over a decade.  The artist who created Kryptos, James Sanborn, has also created other encrypted sculptures such as the decade-old Cyrillic Projector, which was cracked last September by an international team led by Elonka Dunin.  This talk is intended for a general audience with beginning to intermediate cryptographic experience.  Elonka will go over how the code was cracked, and the current state of knowledge about the Kryptos sculpture, its own encrypted messages, and its mysterious CIA surroundings.  Elonka Dunin is a professional game developer, working at Simutronics (, a provider of massively multiplayer online games.  Also an amateur cryptographer, Elonka led the international team that cracked the decade-old KGB Cyrillic Projector Code in September 2003.  Elonka was born in Los Angeles, studied Astronomy at UCLA, and then joined the United States Air Force, where she worked on the SR-71 and U-2 reconnaissance aircraft.  Elonka is a world-traveler who speaks multiple languages, and has visited scores of countries around the world, and every continent (yes, including Antarctica).  She has won awards for cracking various codes, such as when she cracked the PhreakNIC v3.0 Code, an up-until-Elonka unsolved puzzle created by SE2600.  Since September 11th, Elonka has also been helping out with the war on terrorism by teaching government agents about cryptography and what types of codes that Al Qaeda may be using.  She is co-founder of the Kryptos Group, an online group of cryptographers and interested hobbyists trying to crack the last part of the code on the famous Kryptos sculpture at CIA Headquarters.

  33. Richard Thieme - Quantum Hacking: In Search of a Unified Theory  (9.7M MP3)
    • The search for a unified theory of everything in contemporary physics stems in part from the fundamental inability to reconcile quantum physics and relativity theory.  This has pushed research toward complex mathematical models such as string theory in an effort to model a single way of looking at everything.  The same can be said of the distribution of power in networks and hierarchies.  The individual person looks like one kind of thing when viewed in the context of a network and another kind of thing when viewed in the context of a hierarchy.  This is analogous to describing a photon as both a particle and a wave.  The context of our inquiry determines the content that results and the primary object of that inquiry, the "individual person," is revealed to be a social construction, not an empirical fact.  The lack of a unified theory of humanity and computing is one reason we experience cognitive dissonance today.  The notion of the "individual person" is central to current debates about privacy, intellectual property, and the legality or illegality of network aggression ("black hat hacking"), but from the point of view of the distributed network, there is no individual person, there are only nodes in the network.  In addition, we all inhabit nodes in multiple networks simultaneously.  We can field any network-determined identity we choose but we do not determine an individual identityuntil we choose a network identity.  That choice is made in the moment in which we act, so paradoxically, while context determines content, choice is always prior to context and creates it.  Until we choose, it is impossible to predict with certainty which choice will be made and therefore what identity will be fielded.  This is why security based on perimeter defense or authentication is by definition a failed model.  This analysis has profound implications for traditional notions of free will, loyalty, citizenship, and security.  It explains why hackers who evolve from working in online meritocracies to working in corporate structures literally become different people.  It explains why a disciplined hierarchical structure like the military can use network centric warriors and fight networks with networks while maintaining a basic identity for the moment as the machinery of a nation state.  It explains why perspective is worth fifty points of IQ and why perception management creates perspective.  It provides one more example in support of Alfred North Whitehead's assertion that "the major advances in civilizations are processes that all but wreck the societies in which they occur."  We are in search of a unified theory of an emergent multi-nodal cyborg personality and how it exercises power.  This theory must address hierarchical and distributed structures and what they mean for human identity, law, and global organization and geopolitical strategy.  What are the genuine sources of our power?  What is the point of reference from which that power is exercised?  Who do we believe ourselves to be in the moment in which we act and how do we thereby define ourselves not in theory but in practice, not in the chat room but on the field of action?  And finally, why is knowing that we are doomed to fail the key to victory?  Richard Thieme shows how boundaries have morphed, power has been redefined, and The Matrix is more than a movie.  Not since Blade Runner has a film described so well the territory that must be crossed.  Owning our own souls is the ultimate intention of Third Generation Hacking, the only end that justifies the means.  Thieme holds nothing back as he addresses the deeper implications of what it means to be the network.  The stakes are high and the battle is worthy of our best efforts.  This talk is a call to arms to accept responsibility for the life and death battle being waged for the hearts and minds of digital humanity.

  35. Sarah Gordon - What Do You Mean, Privacy?  (7.3M MP3)
    • Privacy doesnt mean the same thing to everyone...  Since you're interacting in a global space, you need to understand what people outside your immediate frame of reference are thinking when they talk about privacy because what they think will influence ttheir expectations and their actions.  This talk will give you the opportunity to examine some other views of privacy, explore your own thinking, and compare it with others both from the global information security community and the audience.  Finally, we'll look at how well those thoughts match up with behaviors related to various aspects of what we call "privacy."  Sarah Gordon has spoken at Defcon on topics from the security of PGP, women of #hack, and the impact of legislation on virus writing, and done lots of security related stuff for lots of different groups.

  36. Kathy Wang - Frustrating OS Fingerprinting with Morph  (24.2M MP3)
    • Sun Tzu once stated, "Know your enemy and know yourself, and in a hundred battles you will never be defeated."  By denying outsiders information about our systems and software, we make it more difficult to mount successful attacks.  There are a wealth of options for OS-fingerprinting today, evolving from basic TCP-flag mangling tools such as Queso, through the ICMP quirk-detection of the original Xprobe, and the packet timing analysis of RING, to today's suite of multiple techniques employed by nmap.  The ultimate advantage in the OS-detection game lies with the defender, however, as it is they who control what packets are sent in response.  Morph is a BSD-licensed remote OS detection spoofing tool.  It is portable and configurable, and will frustrate current state-of-the-art OS fingerprinting.  This presentation will discuss the current techniques used for OS fingerprinting, and how to frustrate them.  A newer version of Morph will be released with the talk, as a concrete example of the discussed techniques.  Kathy Wang broke into programming with BASIC on the Apple IIgs.  She has a bachelor's and master's degree in electrical engineering from the University of Michigan, where she specialized in VLSI chip design and semiconductor device physics and fabrication.  She worked at Digital as part of the Next-Generation Alpha Chip Design Team, and got to spend an entire wonderful summer blowing up Alpha chips.  She has published a paper on some of the work she did there at an IEEE conference.  Kathy has instructed courses ranging from Semiconductor Device Physics to Vulnerability Assessment and Penetration Testing.  Since Digital got broken up by Compaq and Intel, Kathy has focused on the software side of things.  She has worked at Counterpane Internet Security, and currently works as a Senior Infosec Engineer at The MITRE Corporation.  Kathy is also a founder of Syn Ack Labs, a computer security research group focused on cryptography, steganography, and low-level packet hijinks.

  37. Kevin Mahaffey - Smile, You"re on Candid Camera: The Changing Notions of Surveillance in Postmodern America  (55.8M MP3)
    • Recently, surveillance has become somewhat of a pop-culture fascination.  From the Reality TV shows permeating every network's line up to the webcam phenomenon of the late 1990s, surveillance has become more a source of entertainment than ever before.  Benjamin Franklin's quote, Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety, has long served to exemplify the American, Big Brother, notion of surveillance: that the government is the main aggressor and seeks to take away privacy and thereby, liberty.  My talk will contrast traditional perceptions of surveillance in American culture with new notions brought forth in the emerging digital economy.  The privacy of individuals is being bought from individuals through tangible or intangible rewards and resold as demographic data to the highest bidder.  Instead of resisting the reduction of privacy, people are embracing surveillance as a benign improvement of everyday life.  If we continue such a trend, will society be better for it, or will ubiquitous surveillance serve to implement Orwell's nightmare in 1984?  Kevin Mahaffey is an Electrical Engineering student at the University of Southern California.  He has conducted extensive research regarding the sociological effects of the growth of commercial surveillance in American culture.  When not confusing sociology with technology he is the Director of Software Development for Flexilis and is currently developing a few Bluetooth security tools hopefully to be released this year at Defcon.  He also writes the occasional article for and has 6 years of experience working in commercial internet technology.

  39. Brett Moore - Shoot the Messenger Using Window Messages to Exploit Local Win32 Applications  (23.6M MP3)
    • The windows GDI interface uses messages to pass input and events to windows.  As there is currently no way of determining who the sender of the message is, it is possible for a low privileged application to send messages to and interact with a process of higher privilege.  This presentation will cover in details some of the flaws exposed through these messages, and demonstrate how they can be exploited to conduct privilege escalation and other attacks.  Attendees should be familiar with the shatter attack concept and may want to review the following documents before attending: "Shatter Attacks How to break Windows" by Chris Paget, "Win32 Message Vulnerabilities Redux" by Oliver Lavery, "Shattering by Example" by Brett Moore.  Brett Moore leads the security research and network intrusion teams at  He has been credited with the discovery of multiple security vulnerabilities in both private and public software vendors products including Microsoft web products.

  40. Jason Scott - Digitizations And Documentary  (24.3M MP3)
    • Jason Scott of, a site dedicated to the history of dial-up bulletin board systems, embarked on a quest to film an all-inclusive BBS documentary in 2001.  What started out as a one-year project grew to three, and what started as a two-hour film will be a six-hour series.  Thousands of miles of travel and 200 interviews later, the production is now nearing the end of editing and the release date.  Jason tells you what he learned, why you shouldn't hesitate to make your own projects, and the occasional story that technically can't be mentioned in the film.  Jason Scott is the creator and webmaster of, a website dedicated to collecting the files and related materials from the era of the dial-up BBS.  This website, originally built from files he collected as a BBS user in his early teens, has expanded to many gigabytes of data and now recieves thousands of visitors a day.  Inspired to create "the ultimate BBS list" from the hundreds on his website, he suddenly started recieving dozens of stories from BBS users and operators who found their old BBSes listed among others.  Recogizing a missing piece in the story of computers, Jason used his dormant filmmaking skills (Emerson College Film Degree, 1992) to create this documentary.

  41. Sean O'Toole - Mutating the Mutators  (6.1M MP3)
    • Since the introduction of metamorphic stealth in the computer virus world, it has been suggested that the method can also be used to protect any, even legitimate, code.  The only downfall of this technique is that how the engine manipulates the code remains constant.  This allows the original code to be obtained by using an optimizer.  The next step for this stealth method is to create an engine that will change how the code in manipulated.  This speech will outline how to create an engine that integrates random code with alternate encoding of an instruction to create a semi-random set of instructions, which will fit into the metamorphic engine paradigm.  Sean O'Toole is fresh out of college for Computer Science and Mathematics.  He has been playing around with viruses since high school and had also taken independent studies on computer viruses in college.  As well as the above, he also helped institutions such as NCAR use Artificial Life Algorithms for modeling.

    • Until now network security defences have largely been about building walls and fences around the network.  This talk revolves around spiking those walls and electrifying those fences!  During this talk we will highlight techniques (and tools) that can be used to turn the tables on prospective attackers with passive-Strike-Back.  We will explore the possibilities across the assesment spectrum responding to the standard assesment phases of intelligence gathering, reconnaissance and attack with disinformation, misdirection, camouflage, obfuscation and proportional response.  Roelof Temmingh is the technical director of SensePost where his primary function is that of external penetration specialist.  Roelof is internationally recognized for his skills in the assessment of web servers.  He has written various pieces of Perl code as proof of concept for known vulnerabilities, and coded the world-first anti-IDS web proxy "Pudding."  He has spoken at many international conferences and in the past year alone has been a keynote speaker at SummerCon (Holland) and a speaker at The Black Hat Briefings.  Roelof drinks tea and smokes Camels.  Haroon Meer is currently SensePost's director of Development (and coffee drinking).  He specializes in the research and development of new tools and techniques for network penetration and has released several tools, utilities and white-papers to the security community.  He has been a guest speaker at many Security forums including the Black Hat Briefings.  Haroon doesnt drink tea or smoke camels.  Charl van der Walt is a founder member of SensePost.  He studied Computer Science at UNISA, Mathematics at the University of Heidelberg in Germany and has a Diploma in Information Security from the Rand Afrikaans University.  He is an accredited BS7799 Lead Auditor with the British Institute of Standards in London.  Charl has a number of years experience in information security and has been involved in a number of prestigious security projects in Africa, Asia and Europe.  He is a regular speaker at seminars and conferences nationwide and is regularly published on internationally recognized forums like SecurityFocus.  Charl has a dog called Fish.

  43. Doug Mohney - DIGEX At the Dawn of the Commercial Internet  (21.9M MP3)
    • Hearken back to the days of yesterday, circa 1993, when men were men, the Internet "backbone" was T3 and run by ANS, and a few brave start-up companies around Washington D.C. were fighting the phone company and each other to build the "commercial" Internet.  One of them, DIGEX, literally started out in the founder's basement in '92 and rapidly grew to be a major force in what ultimately became known as web hosting.  DIGEX "invented" web hosting, was first to light-up, collected a whole bunch of sites including one for a Langley, VA-based agency, and grew into a 600+ person company with a 1996 IPO.  Doug Mohney was employee #10 at DIGEX and witnessed a whole bunch of stuff from late '93 through 1997.  Doug Mohney was employee #10 at DIGEX.  He is often confused with employee #1 (Doug Humphrey; Mohney does not have Humphrey's beard, wife, or bank balance).  Currently, he is online editor for VON Magazine and a contributor to Mobile Radio Technology magazine.  His first Boardwatch article, a history of DIGEX, was published in 1997 to critical acclaim by most and heartburn by a few.

  45. Thorsten Holz, Maximillian Dornseif, Christian Klein - NoSEBrEaK: Defeating Honeypots  (26.2M MP3)
    • Honeynets are one of the more recent toys in the white-hat arsenal.  They are usually assumed to be hard to detect and attempts to detect or disable them can be unconditionally monitored.  Sometimes it is even suggested that deploying honeynets is a way to incerase security.  We scrutinize this assumption and demonstrate a method how a host in a honeynet can be completely controlled by an attacker without any substantial logging taking place.  We show how to detect honeynets, circumvent logging on a honeynet and finally 0wn a honeynet hard disabling all of a honeypots security features and present the tools to do so.  While being fairly technical the a basic knowledge how shellcode and the like works should be enough to follow the talk.  Thorsten Holz is a research student at the laboratory for dependable distributed systems at RWTH Aachen University where he is trying to bring a solid scientific foundation to Honeynet research.  Maximillian Dornseif and Christian N. Klein have studied computer science at the University of Bonn, Germany; Dornseif also holds a degree in laws.  Both are involved in computer security and the German computer underground, namely the Chaos Computer Club, for a long time and are doing security consulting together since the late nineties.  Their clients include the industry like Deutsche Telekom and T-Mobile but also government.

  46. h1kari - Smart Card Security: From GSM to Parking Meters  (24.8M MP3)
    • Smart Cards are used all over the place in every day life.  The unfortunate (or fortunate) side of Smart Cards is that most widely deployed systems don't use any real security and rely mostly on obscurity.  This presentation will discuss the different types of Smart Cards, exactly how to reverse engineer the protocols they use, and how to exploit their security weaknesses.  For demonstration, we will look at GSM SIM cards and San Diego Parking Meter Debit Cards and show how their security can be defeated.  h1kari has been in the security field for the past 5 years and currently specializes in 802.11b wireless security, Smart Card, and GSM development specifically to exploit its various inherent design weeknesses.  He is the main developer of the bsd-airtools project, a complete 802.11b penetration testing and auditing toolset, that implements all of the current methods of detecting access points as well as breaking wep on them and doing basic protocol analysis and injection.  David has spoken at numerous international conferences on Wireless Security, has published multiple whitepapers, and is regularly interviewed by the media on computer security subjects.  h1kari is also the founder of Nightfall Security Solutions, LLC and one of the founding members of Dachb0den Research Labs, a non-profit southern california based security research think-tank.  He's also currently the chairman of ToorCon Information Security Conference and has helped start many of the security and unix oriented meetings in San Diego, CA.

  49. Jamie Butler - VICE: Catch the Hookers!  (17.4M MP3)
    • Rootkits are the backbone of software penetrations.  They provide stealth and consistent access to a computer system.  Rootkits employ technology for covert ex-filtration of data, IDS evasion, and anti-forensics.  Rootkit technology is now incorporated into the most deadly of threats, network worms.  Serious security professionals must understand rootkit technology in detail.  Commercial anti-virus technology is woefully inadequate at dealing with the threat.  There is no magic security tool that will protect your system.  Rootkits now employ specific methods to evade many security utilities, including Host-based Intrusion Prevention Systems (HIPS).  This talk focuses on specific rootkit threats and more importantly, how intrusion-prevention software can be designed to detect these threats.  Illustrated threats include Direct Kernel Object Manipulation (DKOM), hooking, and runtime code patching.  We will release a new version of our freeware tool, called "VICE," that can detect many of these rootkit threats.  Jamie Butler is the Director of Engineering at HBGary specializing in rootkits and other subversive technologies.  He is the co-author and a teacher of "Aspects of Offensive Root-kit Technologies."  Prior to accepting the position at HBGary, he was a senior developer on the Windows Host Sensor at Enterasys Networks, Inc.  He holds a MS in Computer Science from the University of Maryland, Baltimore County.  Over the past few years his focus has been on Windows servers concentrating in host based intrusion detection and prevention; buffer overflows; and reverse engineering.  Jamie is also a contributor at

  50. Nick Mathewson - Snake Oil Anonymity: How To Spot It, And How Not To Write It  (19.6M MP3)
    • Much software that promises "anonymity" fails to deliver, as witnessed by a succession of compromised file-trading networks, back-doored communications systems, overhyped vapornets, and insecure "improvements" on existing remailer networks.  I'll discuss a bunch of allegedly anonymous systems, and explain how a clever attacker can defeat each of them.  Audience members will learn to recognize the warning signs of broken anonymity in anonymous communications and P2P; and will learn a few principles to help them design the anonymity properties of their own systems.  Nick Mathewson is one of the main designers on Type III (a.k.a. Mixminion), the protocol that will replace the one currently used by the Mixmaster anonymous remail.  He is also the lead developer of the Mixminion software, and a core developer on the Tor anonymizing proxy.  He lives in Cambridge, MA.

    • This talk provides an overview of the RFID Smart Labels, small labels on products with an embedded microchip and an antenna.  Smart Labels store product and serial-number, expiration date, etc. and can be read from a distance.  The industry is planning to put these labels with an international product code on every product within the next decade, effectively replacing the old bar-code system.  Some stores already use Smart Labels, for example certain pharmacies in the US, and in Europe the Metro Group in their Future Store.  At the end of this talk there is a practical demonstration of RF-DUMP, my tool to read and write Smart Labels, check their meta-data and manipulate it.  Mr. Lukas Grunwald is CTO of DN-Systems Enterprise Internet Solutions GmbH (Hildesheim/Germany) a globally acting consulting office working mainly in the field of security and Internet/eCommerce solutions for enterprises.  Mr. Grunwald has been working in the field of IT security for nearly 15 years now.  He is specializing in security of wireless and wired data and communication networks, forensic analysis, audits and active networking.  Mr. Grunwald regularly publishes articles, talks and press releases for specialist publications.  He also participates actively in conferences such as Hackers at Large, Hacking in Progress, Network World, Internet World, Linux World (USA/Europe), Linux Day Luxembourg, Linux Tag, CeBIT Conference.

  52. Tzi-cker Chiueh - Program Semantics Aware Intrusion Detection  (18.6M MP3)
    • One of the most dangerous cybersecurity threats is "control hijacking" attacks, which hijack the control of a victim application, and execute arbitrary system calls assuming the identity of the victim program's effective user.  These types of attacks are viperous because they do not require any special set-up and because production-mode programs with such vulnerabilities appear to be wide spread.  System call monitoring has been touted as an effective defense against control hijacking attacks because it could prevent remote attackers from inflicting damage upon a victim system even if they can successfully compromise certain applications running on the system.  However, the Achilles' heel of the system call monitoring approach is the construction of accurate system call behavior model that minimizes false positives and negatives.  This presentation describes the design, implementation, and evaluation of a program semantics-aware intrusion detection system called PAID, which automatically derives an application-specific system call behavior model from the application's source code, and checks the application's run-time system call pattern against this model to thwart any control hijacking attacks.  The per-application behavior model is in the form of the sites and ordering of system calls made in the application, as well as its partial control flow.  Experiments on a fully working PAID prototype show that PAID can indeed stop attacks that exploit non-standard security holes, such as format string attacks that modify function pointers, and that the run-time latency and throughput penalty of PAID are under 11.66% and 10.44%, respectively, for a set of production-mode network server applications including Apache, sendmail, FTP daemon, etc.  Dr. Tzi-cker Chiueh is currently an associate professor in computer science department of Stony Brook University, and the chief scientist of Rether Networks Inc.  He received his B.S. in electrical engineering from National Taiwan University, M.S. in computer science from Stanford University, and Ph.D. in computer science from University of California at Berkeley in 1984, 1988, and 1992, respectively.  He received a NSF CAREER award in 1995.  Dr. Chiueh's research interest is on computer security, network/storage QoS, and wireless networking.  Dr. Chiueh's group developed the world's fastest array bound checking compiler that incurs less than 10% run-time overhead than programs without checking under GCC, and built the world's fastest disk-based logging system, which accomplishes a single-sector disk write operation within 450 micro-seconds.

  55. Joshua Teitelbaum and Peter Leung - CryptoMail Encrypted Email for All (Including Grandma)  (15.8M MP3)
    • Four years ago, CryptoMail introduced the first secure open source web based email solution.  System administrators and hostile parties no longer had the ability to read a users email.  With functionality similar to Hushmail, the world was introduced to an open source solution that they themselves could host.  At DEFCON 12, will be releasing to the public a major advance in its technology.  Users will now be able to transparently and securely communicate with PGP users.  Users will be able import their private PGP key set upon account creation as well as external PGP public keys.  Architect Joshua Teitelbaum and project manager Peter Leung will present the overall design of the architecture, the infrastructure and the logistics of the upcoming CryptoMail Email System release.  We will demonstrate the technology integration inside the new release for the first time.  At the conference, you will have the chance to preview the new release.  Joshua Teitelbaum developed the CryptoMail Email System and founded in 2000.  Joshua is the primary developer and technical lead of the email system.  He communicates with other developers and members around the world to discuss future features and improvements to the CryptoMail Email System.  Besides information security, Joshua holds an active interest in building scalable trading systems for broker/dealers and portfolio managers.  Peter Leung joined in 2000 as the webmaster and the project manager.  His main task in the organization is to direct, manage, and organize the software release process.  Peter collaborates with other members to document the email system and informs everyone about the organization's activities.  Peter holds a BS in mechanical engineering, BS in mathematics, and MBA from SFSU.

  56. Rebecca Mercuri - Hack the Vote: Election 2004  (30.5M MP3)
    • In the rush to solve problems that emerged from Florida's Presidential election dispute in 2000, computerized voting systems have been deployed in unprecedented numbers.  Estimates indicate that 30% of the USA will be voting on fully electronic equipment offering no capability for independent recounts, and another 50% of the country will be casting ballots tabulated by computer-based scanners.  Vendors and promoters of these systems have made promises of reliability, accuracy and accessibility.  Yet evidence from the 2004 primary season and earlier uses in 2002 and 2003 elections have demonstrated malfunctions resulting in irretrievable loss of vote data, usability issues including county-wide denial of service incidents, and fraud allegations due to software substitutions.  This talk will explore the vulnerabilities of electronic voting systems to insider and outsider attacks, along with the possibilities and ramifications of large-scale vote fraud in the 2004 election and beyond.  Dr. Rebecca Mercuri became an overnight celebrity during the media frenzy that ensued when the U.S. Presidential election ended in a dead heat in November 2000.  A few weeks earlier, she had successfully defended her Doctoral Dissertation "Electronic Vote Tabulation: Checks and Balances" at the University of Pennsylvania, and then found herself writing testimony in the now-legendary Bush v. Gore case that was working its way through the legal system.  Her testimony was presented to the U.S. 11th Circuit Court of Appeals and referenced in the briefs to the U.S. Supreme Court.  Since then, she has provided formal testimony on voting systems to the House Science Committee, Federal Election Commission, U.S. Commission of Civil Rights, and the U.K. Cabinet, has been quoted in the U.S. Congressional Record, and has played a direct role in municipal, state, federal, and international legislative initiatives.  Rebecca's comments on election technology are frequently cited by the media, and she authors the quarterly "Security Watch" column in the Communications of the Association for Computing Machinery (archived at  Having recently completed a research fellowship at the John F. Kennedy School of Government in their Belfer Center for Science and International Affairs, Dr. Mercuri will be moving to Harvard University's Radcliffe Institute in the Fall.  Bev Harris, author of "Black Box Voting: Ballot-Tampering in the 21st Century," began writing on the subject of electronic voting machines in October 2002.  Her investigative journalism has since been cited in The New York Times (three times), and on CBS, Fox News, and CNN.  In writing Black Box Voting, Harris spent over two thousand hours researching voting machines, and interviewed hundreds of witnesses including many election officials and even voting machine programmers who work directly for the firms that build these machines.  During the course of writing Black Box Voting, Harris discovered that one of the largest voting machine companies, Diebold Election Systems, had committed a massive security breach, leaving thousands of sensitive voting system program files on an unprotected web site.  These files have now triggered a national investigation and activism movement to restore clean, trustworthy voting systems.

  57. Adam Laurie and Martin Herfurt - Bluesnarfing: The Risk From Digital Pickpockets  (16.3M MP3)
    • In November 2003, Adam discovered serious flaws in the authentication and data transfer mechanisms on some bluetooth enabled devices, and, in particular, mobile phones including commonly used Nokia, Sony Ericsson and Motorola models.  Shortly thereafter, Martin Herfurt of Salzburg Research Forschungsgesellschaft mbH expanded on these problems, and teamed up with Adam to investigate further.  This talk will cover the issues arising out of these flaws, including loss of personal data, identity theft, phone tapping, tracking, fraud and theft of service.  The threat to individuals and corporates will be examined, and statistics and examples from the real world presented, as well as live demonstrations of each of the problems.  Details of how the industry reacted, what they did, didn't and should have done will also be discussed.  This will be a fun talk and a real eye-opener for those with Bluetooth enabled devices.  Adam Laurie is Chief Security Officer and Director of AL Digital Ltd.  He started in the computer industry in the late Seventies, working as a computer programmer on PDP-8 and other mini computers, and then on various Unix, DOS and CP/M based micro computers as they emerged in the Eighties.  He quickly became interested in the underlying network and data protocols, and moved his attention to those areas and away from programming, starting a data conversion company which rapidly grew to become Europe's largest specialist in that field (A.L. downloading Services).  During this period, he successfully disproved the industry lie that music CDs could not be read by computers, and, with help from his brother Ben, wrote the world's first CD ripper, "CDGRAB."  At this point, he and Ben became interested in the newly emerging concept of "The Internet", and were involved in various early open source projects, the most well known of which is probably their own "Apache-SSL" which went on to become the de-facto standard secure web server.  Since the late Nineties they have focused their attention on security, and have been the authors of various papers exposing flaws in Internet services and/or software, as well as pioneering the concept of re-using military data centres (housed in underground nuclear bunkers) as secure hosting facilities.  Adam has been a senior member of staff at Defcon since 1997, and also acted as a member of staff during the early years of the Black Hat Briefings.
