The International Subversives

Best of all, Crays were master password crackers. The computer would go through Mendax's entire password cracking dictionary in just ten seconds. An encrypted password file would simply melt like butter in a fire. To a hacker, it was a beautiful sight, and Corrupt handing a few Cray accounts over to Mendax was a friendly show of mutual respect.

Mendax reciprocated by offering Corrupt a couple of accounts on Encore. The two hackers chatted off and on and even tried to get Corrupt into NorTel. No luck. Not even two of the world's most notable hackers, working in tandem 10 000 miles apart, could get Corrupt through the firewall. The two hackers talked now and again, exchanging information about what their respective feds were up to and sharing the occasional account on interesting systems.

The flat structure of the NorTel network created a good challenge since the only way to find out what was in a partic- ular site, and its importance, was to invade the site itself. The IS hackers spent hours most nights roving through the vast system. The next morning one of them might call another to share tales of the latest exploits or a good laugh about a particularly funny piece of pilfered email. They were in high spirits about their adventures.

Then, one balmy spring night, things changed.

Mendax logged into NMELH1 about 2.30 a.m. As usual, he began by checking the logs which showed what the system operators had been doing. Mendax did this to make sure the NorTel officials were not onto IS and were not, for example, tracing the telephone call.

Something was wrong. The logs showed that a NorTel system admin had stumbled upon one of their secret direc- tories of files about an hour ago. Mendax couldn't figure out how he had found the files, but this was very serious. If the admin realised there was a hacker in the network he might call the AFP.

Mendax used the logs of the korn shell, called KSH, to secretly watch what the admin was doing. The korn shell
