A second suspected LulzSec hacker was arrested Tuesday on charges he took part in an extensive computer breach of Sony Pictures Entertainment, Reuters reports. Raynaldo Rivera, 20, of Tempe, Arizona, surrendered to U.S. authorities in Phoenix six days after a Los Angeles federal grand jury accused him and co-conspirators of stealing information from Sony Pictures’ computer systems in May and June 2011. LulzSec then boasted about the breach and published names, birth dates, addresses, emails, phone numbers and passwords of thousands of people who had entered contests promoted by Sony. An accused British hacker, Ryan Cleary, 20, was indicted by a federal grand jury in June on charges related to LulzSec attacks on media companies including Sony Pictures, Fox Entertainment Group and PBS. The FBI said Rivera’s co-conspirators included Cody Kretsinger, 24, a confessed LulzSec member who pleaded guilty in April to federal charges in the Sony attack. Kretsinger is slated to be sentenced on October 25.
