• A 20-year-old Arizona man, Raynaldo Rivera of Tempe, arrested in August by FBI agents, pled guilty in a California court to intentionally causing damage to the website of Sony Pictures Entertainment in an attack carried out in May 2011. A former member of the hacker group Lulzsec, Rivera also admitted to launching a SQL injection attack against sonypictures.com that allowed him to extract confidential and personal information from the website's database, which was published online. The plea agreement noted this had resulted in losses of about $605,000 to Sony to cope with the attack, including computer forensics and staff call centers and credit monitoring for individuals whose personal information was compromised. In exchange for his guilty plea, Rivera, though facing 15 years in prison, could get a reduced sentence, with that decision expected to be determined at a hearing scheduled for March 14, 2013.
