A federal grand jury in Los Angeles has indicted a 20-year-old Brit on charges related to the hacking of computer systems at Fox Entertainment Group, Sony Pictures Entertainment movie and TV studio as well as PBS, Reuters reports. Ryan Cleary is already in jail in the UK, accused of hacking computers with the group LulzSec. He was indicted on Tuesday. LulzSec, an offshoot of global hacking group Anonymous, has taken credit for hacking attacks on government and corporate websites. LulzSec hacker Cody Kretsinger two months ago pleaded guilty in U.S. District Court in Los Angeles to taking part in an extensive computer breach at Sony’s studios. Prior to that Anonymous leader “Sabu” or Hector Xavier Monsegur, had pleaded guilty to hacking charges and provided the FBI information on fellow hackers.
