The Secret Service was less than satisfied with this rapier-like hacker logic.

Then there was the issue of crashing the phone system. No problem, Urvile admitted sunnily. Atlanta LoD could have shut down phone service all over Atlanta any time they liked. EVEN THE 911 SERVICE? Nothing special about that, Urvile explained patiently. Bring the switch to its knees, with say the UNIX "makedir" bug, and 911 goes down too as a matter of course. The 911 system wasn't very interesting, frankly. It might be tremendously interesting to cops (for odd reasons of their own), but as technical challenges went, the 911 service was yawnsville.

So of course the Atlanta Three could crash service. They probably could have crashed service all over BellSouth territory, if they'd worked at it for a while. But Atlanta LoD weren't crashers. Only losers and rodents were crashers. LoD were ELITE.

Urvile was privately convinced that sheer technical expertise could win him free of any kind of problem. As far as he was concerned, elite status in the digital underground had placed him permanently beyond the intellectual grasp of cops and straights. Urvile had a lot to learn.

Of the three LoD stalwarts, Prophet was in the most direct trouble. Prophet was a UNIX programming expert who burrowed in and out of the Internet as a matter of course. He'd started his hacking career at around age 14, meddling with a UNIX mainframe system at the University of North Carolina.

Prophet himself had written the handy Legion of Doom file "UNIX Use and Security From the Ground Up." UNIX (pronounced "you-nicks") is a powerful, flexible computer operating-system, for multi-user, multi-tasking computers. In 1969, when UNIX was created in Bell Labs, such computers were exclusive to large corporations and universities, but today UNIX is run on thousands of powerful home machines. UNIX was particularly well-suited to telecommunications programming, and had become a standard in the field. Naturally, UNIX also became a standard for the elite hacker and phone phreak. Lately, Prophet had not been so active as Leftist and Urvile, but Prophet was a recidivist. In 1986, when he was eighteen, Prophet had been convicted of "unauthorized access to a computer network" in North Carolina. He'd been discovered breaking into the Southern Bell Data Network, a UNIX-based internal telco network supposedly closed to the public. He'd gotten a typical hacker sentence: six months suspended, 120 hours community service, and three years' probation.

After that humiliating bust, Prophet had gotten rid of most of his tonnage of illicit phreak and hacker data, and had tried to go straight. He was, after all, still on probation. But by the autumn of 1988, the temptations of cyberspace had proved too much for young Prophet, and he was shoulder-to-shoulder with Urvile and Leftist into some of the hairiest systems around.

In early September 1988, he'd broken into BellSouth's centralized automation system, AIMSX or "Advanced Information Management System." AIMSX was an internal business network for BellSouth, where telco employees stored electronic mail, databases, memos, and calendars, and did text processing. Since AIMSX did not have public dial-ups, it was considered utterly invisible to the public, and was not well-secured—it didn't even require passwords. Prophet abused an account known as "waa1," the personal account of an unsuspecting telco employee. Disguised as the owner of waa1, Prophet made about ten visits to AIMSX.

Prophet did not damage or delete anything in the system. His presence in AIMSX was harmless and almost invisible. But he could not rest content with that.

One particular piece of processed text on AIMSX was a telco document known as "Bell South Standard Practice 660-225-104SV Control Office Administration of Enhanced 911 Services for Special Services and Major Account Centers dated March 1988."
