Kevin Poulsen's hacker handle was "Dark Dante". He worked for SRI International by day, and hacked at night. He trained to be the complete hacker, and even taught himself lock picking. Among other things, he reactivated old Yellow Page escort telephone numbers for an acquaintance that then ran a virtual agency.

When the FBI started pursuing Kevin, he went underground as a fugitive. When he was featured on NBC's Unsolved Mysteries, the show's 1-800 telephone lines mysteriously crashed. He was finally arrested in April, 1991. Poulsen is now a journalist, and serves as editorial director for SecurityFocus.

His best known hack was a takeover of all of the telephone lines for Los Angeles radio station KIIS-FM, guaranteeing that he would be the 102nd caller, and winning a Porsche 944 S2. In June 1994, Kevin pleaded guilty to seven counts of mail, wire and computer fraud, money laundering, and obstruction of justice, and was sentenced to 51 months in prison and ordered to pay $56,000 in restitution. It was the longest sentence ever given for hacking. He also pleaded guilty to breaking into computers and obtaining information on undercover businesses run by the FBI.
