Kevin Mitnick has pleaded guilty to computer hacking charges and will receive a sentence of five years and eight months, with three years and 10 months left to serve.
Mitnick pleaded guilty to seven counts of wire and computer fraud and interception of wire communications, and was handed the longest sentence for a hacker in US history, said Assistant US Attorney David Schindler.
Mitnick could be eligible for early release to a half-way house early next year, and will be subject to three years supervised release when he gets out of jail, Schindler said. As part of the plea bargain, Mitnick's access to computers will be restricted and he has signed over the rights to any profits from his story, according to Schindler.
Sentencing is scheduled for June 14.
Mitnick has already served 14 months for violating his supervised release in 1988 and 1989 when he began his hacking spree, and another eight months for related charges, Schindler said.
The 35-year-old Mitnick was arrested four years ago for breaking into computer networks and stealing credit card numbers and software. He pleaded guilty to similar crimes in 1989 and 1996. His capture was the subject of a book entitled Takedown. In the past year, supporters have vandalised or shut down web sites, including The New York Times, to protest his incarceration.
