A hacker who pleaded guilty to taking part in an extensive computer breach of Sony Pictures Entertainment has been sentenced to a year in prison, followed by home detention, US federal prosecutors said.
Cody Kretsinger, a LulzSec hacker who used the online moniker “Recursion”, pleaded guilty in April 2012 to one count each of conspiracy and unauthorised impairment of a protected computer as part of a plea agreement with prosecutors.
According to Reuters, LulzSec, an offshoot of the international hacking group Anonymous, has taken credit for hacking attacks on government and private sector websites.
Kretsinger, 25, was also ordered by a US district judge in Los Angeles to perform 1000 hours of community service after his release from prison, said Thom Mrozek, spokesman for the US Attorney’s Office in Los Angeles.
During last year’s plea hearing, Kretsinger told a federal judge that he gained access to the Sony Pictures website and gave the information he found there to other members of LulzSec, who posted it on the group’s website and Twitter.
Prosecutors said Kretsinger and other LulzSec hackers ultimately caused the unit of Sony more than $US600,000 in damage.
Kretsinger’s plea came a month after court documents revealed that Anonymous leader “Sabu”, whose real name is Hector Xavier Monsegur, had pleaded guilty to hacking-related charges and provided the FBI with information on fellow hackers.
Prosecutors have declined to say if Kretsinger was also co-operating with authorities in exchange for leniency.
Anonymous and its offshoots, including LulzSec and AntiSec, focused initially on fighting attempts at internet regulation and the blocking of free illegal downloads, but have since taken on other targets including Scientology and the global banking system.
Anonymous, and LulzSec in particular, grabbed the spotlight in late 2010 when they launched what they called the “first cyber war” in retaliation for attempts to shut down the Wikileaks website.
Last week a 26-year-old British man pleaded guilty to carrying out cyber attacks on targets including Sony and Nintendo as part of LulzSec while using the online persona of a 16-year-old girl named Kayla.
