"To carry out the attack, Kretsinger allegedly used a proxy server to disguise his computer's IP address, then obtained confidential information from Sony's network using an SQL injection - a technique used by hackers to exploit vulnerabilities and steal information, according to the FBI. The indictment also alleges that, in order to avoid detection by law enforcement, Kretsinger erased the hard drive of the computer he used to conduct the attack."
