- It turns out that there are several Japanese handheld transceivers (HT's)
- availible in the US for use by ham radio hobbyists that have hidden
- features allowing them to operate in the 800MHz band used by cellular
- telephones. Using an FSK decoder chip and a personal computer running an
- assembly language program to record and decypher the ID beeps at the beginning
- of cellular calls, a "phone book" of cellular ID's can be compiled. A simple
- FSK oscillator controlled by the PC can then be used to dial out using the
- Handheld Transceiver and the captured ID codes.
-
- A low tech analysis could be done by taping the beeps and playing them back
- at slow speed into an oscilloscope. An edited tape may even be adequate for
- retransmission; no decyphering required.
-
- Several radio stores in Los Angeles sell the HT's and have given advice in
- the past about how to access the hidden out-of-band tuning features in the
- ROMS of the Japanese HT's. It's possible now to listen in to cellular
- phone conversations without building any special hardware. In fact if you
- have a good antenna, or live near a cellular repeater tower, you can
- pick up celluar calls using a UHF TV with a sliding tuner by tuning in
- "channels" between 72 and 83 on the UHF dial.
-
- Beside the obvious benefits of unlimited, untraceable, national mobile
- voice communication, there are other uses for cellular hacking.
- For instance: most people using cellular phones are pretty upscale.
- It may be possible to scan for ID codes of the telephones of major
- corporations and their executives and get insider stock trading information.
- Simply by logging the called and calling parties you will be able to compile
- a database mapping out the executive level command & communication structure.
- If this is linked to a remote controlled tape deck you will know precisely
- what is going on and be able to note any unusual activity, such as calls
- between the executives of corporations that are in a takeover or leveraged
- buy out relationship. It is even likely that you will occasionally intercept
- calls between investors and their stock brokers, or calls discussing plans
- for new contracts.
-
- This data is most safely used for insider trading of your own; there will be
- no way that the Securities and Exchange Commission can establish a link
- between you and the insiders. A more risky proposition would be to offer any
- intelligence gathered to competitors for a price as industrial espionage.
-
- Then there are the anarchy & disruption angles for cybernetic guerrilla
- action at the corporate economic & financial level. Leaking info to the
- press can kill a deal or move stock prices prematurely. Intelligence
- gathered via cellular hacking can also be used to plan operations against
- corporate mainframes by providing names and keywords, or indicating vital
- information to be searched for. Listening to the phone calls of candidates
- and their campaign staff is also a field rich in possibilities.
-
- A related technology waiting to be hacked is the nationwide net of pocket
- pagers. The possibilities for executive harrassment using beeper technology
- are relatively unexplored.
-
- There are also several on-line instant stock & commodity quotation systems
- that use SCA subcarriers to transmit investment data. By watching activity
- on these networks you will be able to look over the shoulder of investors
- as they plan their strategy - what kind of inquiries are they making and what
- the results are.
-
- Here are a few of the online investment services (business offices, ca.1987)
-
- DATAQUICK 1-800-762-DATA (voice) Southern CA Real Property Data
- Lotus Signal/QuoTrek 1-800-272-2855 (voice) Stock Market Data
- 1-800-433-6955 (voice)
- FutureSource 1-800-621-2628 ext.34 (voice) Futures Trading Data
- (Or check recent ads in Wall Street Journal etc.)
-
- At any rate, I propose that we start pooling info about cellular phones
- toward the goal of building a 'rosetta stone' of cellular dialing protocols,
- frequencies, technical info and hardware/software hacks.
-
- High on the hit list is a service/repair manual for a cellular phone, and
- journal or technical articles about the inner workings of the cellular
- phone system.
