Kevin Poulsen is the news editor of Wired.com and author of Kingpin: How One Hacker Took Over the Billion-Dollar Cyber Crime Underground (February 2011, Crown), the story of the white hat hacker Max Vision and his turn to the dark side of the for-profit carding underground. Poulsen is a former hacker, whose best known hack involved penetrating telephone company computers in the early 1990s to win radio station phone-in contests. By taking over all the phone lines leading to Los Angeles radio stations, he was able to guarantee that he would be the proper-numbered caller to win, for example, $20,000 in cash, and a Porsche 944 S2 Cabriolet. When the FBI started pursuing Poulsen, he went underground as a fugitive. He was featured on NBC's Unsolved Mysteries, and was finally arrested in April 1991 after 18 months on the run. He pleaded guilty to computer fraud and served a little over 5 years in prison. At the time, it was the longest U.S. sentence ever given for hacking. Following his release from prison Poulsen was briefly barred from using computers. Reformed, but still possessed of the curiosity that contributed to his hacking when he was younger, he became a journalist. His first magazine feature ran in WIRED in 1998, and covered computer programmers who were driven to survivalist tactics by fear of the looming Y2K bug. When Poulsen's court supervision expired, he joined a California-based web start-up called SecurityFocus as editorial director in 2000, and began reporting security and hacking news. Poulsen repeatedly broke stories of national importance that were picked up by the mainstream press: a computer intrusion at a U.S. hospital that, for the first time, breached patient medical records ; hackers "war driving" for open Wi-Fi networks; a computer virus crippling a safety system at a nuclear power plant in Ohio; a southern California hacker's successful penetration of a Secret Service agent's PDA, and the attendant theft of confidential agency files. Poulsen left SecurityFocus in 2005 and joined Wired.com, where he now serves as a news editor. In a computer-assisted reporting effort in 2006, Poulsen wrote software that scoured MySpace for registered sex offenders, identifying hundreds. The story resulted in the arrest of an active pedophile, led to significant policy changes at MySpace and spawned federal legislation. In 2007, Poulsen's reporting revealed that the FBI had been using a custom spyware program, called a CIPAV, to infect the computers of criminal suspects. In June 2010, Poulsen and a co-writer broke the news that the government had secretly arrested Army intelligence analyst Bradley Manning on suspicion of leaking hundreds of thousands of classified documents to the secret-spilling website WikiLeaks. Poulsen is the founding editor of Wired's Threat Level blog, which won the 2008 Knight-Batten Award for Innovation in Journalism, and the 2010 MIN award for best blog. In 2009 Poulsen was inducted into MIN's Digital Hall of Fame for online journalism, and in 2010 he was among those honored as a "Top Cyber Security Journalist" in a peer-voted award by the SANS Institute. Poulsen's encyclopedic knowledge of "I Love Lucy" trivia helped propel his team to victory in Hacker Jeopardy at DEF CON 8.
