Kevin Poulsen (Block Hat Crackers)

1. Also known as Dark Dante, Poulsen gained recognition for his hack of LA radio's KIIS-FM phone lines, which earned him a brand new Porsche, among other items. Law enforcement dubbed him "the Hannibal Lecter of computer crime."
   Authorities began to pursue Poulsen after he hacked into a federal investigation database. During this pursuit, he further drew the ire of the FBI by hacking into federal computers for wiretap information.
   His hacking specialty, however, revolved around telephones. Poulsen's most famous hack, KIIS-FM, was accomplished by taking over all of the station's phone lines. In a related feat, Poulsen also "reactivated old Yellow Page escort telephone numbers for an acquaintance who then ran a virtual escort agency." Later, when his photo came up on the show Unsolved Mysteries, 1-800 phone lines for the program crashed. Ultimately, Poulsen was captured in a supermarket and served a sentence of five years.
   Since serving time, Poulsen has worked as a journalist. He is now a senior editor for Wired News. His most prominent article details his work on identifying 744 sex offenders with MySpace profiles.
