03/20/97 Digital Cellular Encryption Cracked

Authentication - The cellular carrier's latest weapon in fighting cellular phraud.

Wierd tidbit: A correspondent reports: "Some people are paying Digital Rates & using Analog phones, they program their phone with a Digital ESN & give that to the Cell Carrier then just us the Analog side of the system w/ any AMPS phone, don't ask me-I aint tried it so I don't know about that one." Motorola phones use different ESN prefixes for digital phones, so one could simply use RadioPhone's ESN Prefix Table to make up a D-AMPS (TDMA) ESN.

Monitoring Cellular System Data streams. - i.e., with "DDI" boxes.

GSM - International digital cellular

Read the Wireless Week article of August 12, 1996 about RadioPhone, and my responses.

CDPD means data transmission over AMPS cellular.

Easy ESN will read your ESN back to you.

By now, most people involved in the Cellular & Wireless hobby scene have heard about the Celco 51 bbs related arrests. Many people had been suspicious of this board from the very beginning. It was way too expensive a setup for ten average hobbyists to afford. It had multiple toll-free numbers. It had been advertised everywhere conceivable, yet had much blatantly illegal information on it. Much of the requests for this information came from the Informant, PMF, and the FBI agent, Carter One. If it sounds too good to be true, it probably is. and it was. Sooner or later, some impovershed hacker with the technical know-how was bound to get greedy and give in to the entrapment of the FBI, money in exchange for ESNs. While I think that this sort of deal is plain old organized crime, and that it should be punished, the FBI's actions smack of entrapment. It will be interesting to see what the courts will find. This could possibly be the FBI's "ruby ridge".

A few FTP sites around the net have cellular info. Most of the stuff I have seen is old, duplicated a thousand times, and poorly maintained. But try your luck.
