System X

From Chapter 10 - "Anthrax - The Outsider"

Note: System X's name has been changed for legal reasons.


Sometimes the time just slipped away, hacking all night. When the first hint of dawn snuck up on him, he was invariably in the middle of some exciting journey. But duty was duty, and it had to be done. So Anthrax pressed control S to freeze his screen, unfurled the prayer mat with its built-in compass, faced Mecca, knelt down and did two sets of prayers before sunrise. Ten minutes later he rolled the prayer mat up, slid back into his chair, typed control Q to release the pause on his computer and picked up where he left off.

This company's computer system seemed to confirm what he had begun to suspect. System X was the first stage of a project, the rest of which was under development. He found a number of tables and reports in System X's files. The reports carried headers like 'Traffic Analysis', 'calls in' and 'calls out', 'failure rate'. It all began to make sense to Anthrax.

System X called up each of the military telephone exchanges in that list. It logged in using the computer-generated name and password. Once inside, a program in System X polled the exchange for important statistics, such as the number of calls coming in and out of the base. This information was then stored on System X. Whenever someone wanted a report on something, for example, the military sites with the most incoming calls over the past 24 hours, he or she would simply ask System X to compile the information. All of this was done automatically.

Anthrax had read some email suggesting that changes to an exchange, such as adding new telephone lines on the base, had been handled manually, but this job was soon to be done automatically by System X. It made sense. The maintenance time spent by humans would be cut dramatically.

A machine which gathers statistics and services phone exchanges remotely doesn't sound very sexy on the face of it, until you begin to consider what you could do with something like that. You could sell it to a foreign power interested in the level of activity at a certain base at a particular time. And that is just the beginning.

You could tap any unencrypted line going in or out of any of the 100 or so exchanges and listen in to sensitive military discussions. Just a few commands makes you a fly on the wall of a general's conversation to the head of a base in the Philippines. Anti-government rebels in that country might pay a pretty penny for getting intelligence on the US forces.

All of those options paled next to the most striking power wielded by a hacker who had unlimited access to System X and the 100 or so telephone exchanges. He could take down that US military voice communications system almost overnight, and he could do it automatically. The potential for havoc creation was breathtaking. It would be a small matter for a skilled programmer to alter the automated program used by System X. Instead of using its dozen or more modems to dial all the exchanges overnight and poll them for statistics, System X could be instructed to call them overnight and reprogram the exchanges.
