The Prisoner's Dilemma

the clearer it became that the email must have been referring to someone else. They ran through the list of other options and Anthrax’s name came up as a possibility. The IS hackers had all seen him around a few systems and BBSes. Trax had even spoken to him once on a conference call with another phreaker. They pieced together what they knew of him and the picture fitted. The AFP were onto Anthrax and they seemed to know a lot about him. They had traced his telephone connection back to his house. They knew his age, which implied they knew his name. The phone bills were in his parents’ names, so there may have been some personal surveillance of him. The Feds were so close they were all but treading on his heels. The IS hackers had been keeping an eye out for him, to warn him, but this was the first time they had found him.

Anthrax thanked Prime Suspect and got out of the system. He sat frozen in the night stillness. It was one thing to contemplate getting caught, to carry mixed emotions on the hypothetical situation. It was another to have the real prospect staring you in the face. In the morning, he gathered up all his hacking papers, notes, manuals — everything. Three trunks’ worth of material. He carried it all to the back garden, lit a bonfire and watched it burn. He vowed to give up hacking forever.

And he did give it up, for a time. But a few months later he somehow found himself back in front of his computer screen, with his modem purring. It was so tempting, so hard to let go. The police had never shown up. Months had come and gone, still nothing. Prime Suspect must have been wrong. Perhaps the AFP were after another hacker entirely.

Then, in October 1991, the AFP busted Prime Suspect, Mendax and Trax. But Anthrax continued to hack, mostly on his own as usual, for another two years. He reminded himself that the IS hackers worked in a team. If the police hadn’t nailed him when they busted the others, surely they would never find him now. Further, he had become more skilled as a hacker, better at covering his tracks, less likely to draw atten- tion to himself. He had other rationalisations too. The town
