Sometimes hackers can appear perfectly innocuous in their day-to-day lives. Take Kevin Poulsen, who is now News Editor for wired.com – a popular and legitimate site favored by geeks. But he was once a black-hat hacker, pulling off such stunts as winning a Porsche 944 S2 from KIIS-FM by hacking their phone lines and guaranteeing he was the 102nd caller. Like other hackers, he has used his powers for the greater good by identifying MySpace users who were looking for child porn. But he also hacked into the FBI computers and ending up serving a 5-year sentence for his crimes. Since his release, he’s concentrated on his writing career not just at wired but also with his book “Kingpin”. A versatile and, it would seem, reformed hacker.
