THAT was power.

It wasn't like Anthrax screaming at his father until his voice turned to a whisper, all for nothing. He could make people sit up and take notice with this sort of power.

Hacking a system gave him a sense of control. Getting root on a system always gave him an adrenalin rush for just that reason. It meant the system was his, he could do whatever he wanted, he could run whatever processes or programs he desired, he could remove other users he didn't want using his system. He thought, I own the system. The word 'own' anchored the phrase which circled through his thoughts again and again when he successfully hacked a system.

The sense of ownership was almost passionate, rippled with streaks of obsession and jealousy. At any given moment, Anthrax had a list of systems he owned and that had captured his interest for that moment. Anthrax hated seeing a system administrator logging onto one of those systems. It was an invasion. It was as though Anthrax had just got this woman he had been after for some time alone in a room with the door closed. Then, just as he was getting to know her, this other guy had barged in, sat down on the couch and started talking to her.

It was never enough to look at a system from a distance and know he could hack it if he wanted to. Anthrax had to actually hack the system. He had to own it. He needed to see what was inside the system, to know exactly what it was he owned.

The worst thing admins could do was to fiddle with system security. That made Anthrax burn with anger. If Anthrax was on-line, silently observing the adminsŐ activities, he would feel a sudden urge to log them off. He wanted to punish them. Wanted them to know he was into their system. And yet, at the same time, he didnŐt want them to know. Logging them off would draw attention to himself, but the two desires pulled at him from opposite directions. What Anthrax really wanted was for the admins to know he controlled their system, but for them not to be able to do anything about it. He wanted them to be helpless.

Anthrax decided to keep undercover. But he contemplated the power of having System X's list of telephone exchange dial-ups and their username - password combinations. Normally, it would take days for a single hacker with his lone modem to have much impact on the US military's communications network. Sure, he could take down a few exchanges before the military wised up and started protecting themselves. It was like hacking a military computer. You could take out a machine here, a system there. But the essence of the power of System X was being able to use its own resources to orchestrate widespread pandemonium quickly and quietly.

Anthrax defines power as the potential for real world impact. At that moment of discovery and realisation, the real world impact of hacking System X looked good. The telecommunications company computer seemed like a good place to hang up a sniffer, so he plugged one into the machine and decided to return in a little while. Then he logged out and went to bed.

When he revisited the sniffer a day or so later, Anthrax received a rude shock. Scrolling through the sniffer file, he did a double take on one of the entries. Someone had logged into the company's system using his special login patch password.

He tried to stay calm. He thought hard. When was the last time he had logged into the system using that special password? Could his sniffer have logged himself on an earlier hacking session? It did happen occasionally. Hackers sometimes gave themselves quite a fright. In the seamless days and nights of hacking dozens of systems, it was easy to forget the last time you logged into a particular system using the special password. The more he thought, the more he was absolutely sure. He hadn't logged into the system again.

Which left the obvious question. Who had?
