UNDERGROUND

Par felt nervous. In addition to messing around with the phone company's networks, he had been hacking into a Russian computer network from the computer chalet. The Soviet network was a shiny new toy. It had only been connected to the rest of the world's global packet-switched network for about a month, which made it particularly attractive virgin territory.

Nibbler called in a friend to check the motel's phones. The friend, a former telephone company technician turned free- lancer, came over to look at the equipment. He told Nibbler and Par that something weird was happening in the motel's phone system. The line voltages were way off.

Par realised instantly what was going on. The system was being monitored. Every line coming in and going out was probably being tapped, which meant only one thing. Someone – the phone company, the local police, the FBI or the Secret Service – was onto him.

Nibbler and Par quickly packed up all Nibbler's computer gear, along with Par's hacking notes, and moved to another motel across town. They had to shut down all their hacking activities and cover their tracks.

Par had left programs running which sniffed people's pass- words and login names on a continual basis as they logged in, then dumped all the information into a file on the hacked machine. He checked that file every day or so. If he didn't shut the programs down, the log file would grow until it was so big the system administrator would become curious and have a look. When he discovered that his system had been hacked he would close the security holes. Par would have problems getting back into that system.

After they finished tidying up the hacked systems, they gathered up all Par's notes and Nibbler's computer equipment once again and stashed them in a rented storage space. Then they drove back to the motel.

Par couldn't afford to move on just yet. Besides, maybe only the telephone company had taken an interest in the motel's phone system. Par had done a lot of poking and prodding
