An offshoot of Anonymous, hacktivist group Lulzsec in June 2011 hacked into Sony Pictures via SQL Injection attack and stole data that included names, passwords, email, and home addresses of thousands of customers.
Lulzsec, saying the attack was retaliation for Sony's legal action against hacker George Hotz for jailbreaking the PlayStation 3, claimed to have compromised more than one million accounts. Sony has claimed the number of compromised accounts was much lower.
Lulzsec has since been associated with several other statement-making attacks. Founding Lulzec member Sabu (real name Hector Xavier Monsegur) was arrested by federal agents in June 2011 and eventually plead guilty to criminal charges, including multiple counts of conspiracy to engage in computer hacking.
