3. Kevin Poulsen

Poulsen has had perhaps the most successful post-hacking career of anyone on this list. During his time as a miscreant, he used his talent for largely silly purposes (like the time he rigged LA radio station KIIS-FM so he could win a Porsche). He was the first person in the world who was banned from using the Internet following his release from prison. After jail, Poulsen levied his talent and minor celebrity status into a job writing for Wired magazine, and has a lucrative career on the public speaking circuit.
