JEFFERSON VALLEY, NEW YORK, U.S.A., 1991 OCT 1 (NB) -- Cyberpunk co-author Katie Hafner, in an interview with Newsbytes, has responded to allegations of fabrication raised by Kevin Mitnick, one of the main subjects of the book. Cyberpunk: Outlaws and Hackers on the Computer Frontier (Katie Hafner and John Markoff; Simon & Schuster, 1991 - $22.95) devotes the first section of the book called "Kevin: The Dark Side Hacker" to the activities of Mitnick and his associates, Lenny DiCicco, "Susan Thunder" and "Roscoe" (the last two names are pseudonyms; the persons would be interviewed only under the protection of anonymity). Mitnick, who served a prison term related to his intrusions into Digital Equipment Corporation's systems, says in a letter to the Summer 1991 issue of 2600: The Hacker Quarterly that the section concerning him "is 20% fabricated and libelous." Mitnick, in the letter, suggests that the authors had motivation for the alleged unfairness. He said "It seems that the authors acted with malice to cause me harm after my refusal to cooperate. Interestingly, I did offer to participate as a factual information source if I was compensated for my time, but the authors refused, claiming it would taint my objectivity. So, consequently, I declined to cooperate." Hafner confirmed that Mitnick had refused cooperation after his offer to meet for pay was rejected but denied that his action caused any malicious or unfair behavior. She said "I feel that the payment of interview subjects is completely unethical and I have never been involved in such a thing and did not intend to start then. We mentioned in the book that Kevin had refused to cooperate but did not reveal that he had asked for payment. Since he has not brought the subject up, both in a call to the Tom Snyder radio show when I was on and in the 2600 letter, I will confirm the fact that his non-cooperation was due to our refusal to pay." Hafner continued "Mitnick's lack of cooperation certainly did not lead to any malice or bias directed toward him. Everything in the book is, to the best of my knowledge, factual and we did everything possible to insure its accuracy. We attempted to get a confirming source for everything we were told and interviewed dozens of persons for the Dark Hacker section alone." 'Kevin's lack of cooperation did make the job more difficult and, may have possibly hurt him. If he had been willing to talk, he would have had an opportunity to respond to other people's statements about him but, even though we sent him numerous "return receipt" and overnight letters asking him to meet with us, he refused. Two cases in point: in the 2600 letter, he says that we described him as always eating in a computer room while talking on the telephone to Bonnie, his future wife. He denies this and says that I was trying to 'paint an unsavory picture'. It was Bonnie who told us that he was always eating while he was talking -- we didn't make it up -- and without the ability to speak to him, we had to choose to go on." Hafner went on: "The second example is his statement that we said that he taunted USC's Mark Brown when, in fact, he 'never spoke with Mark Brown'. Brown says that he has definitely spoken to Mitnick and that he remembers the calls well and can call to mind details from them. If we had spoken to Mitnick, he would have had a chance to dispute such statements. In response to Mitnick's object to the authors' changing of items that would possibly identify DiCicco as an unemployment cheat, Hafner said "That was my call. We tried to protect identities wherever it was desired. Lenny asked us to change the name and we did just as we also used public aliases for 'Roscoe' and 'Susan Thunder' at their request. Contrary to Kevin's statement, Lenny has not been travelling around with us promoting the book and has received no benefit from it other than the ability to tell his story as he understands it."
