In late 2008, a Pennsylvania teenager playing SOCOM U.S. Navy Seals got kicked out of a tournament for using a cheat mod. So he took revenge by crashing the PlayStation web site for 11 days.
Sony got the last laugh, however, in the form of a federal grand jury investigation, which quickly led to the perpetrator, a high school honors student in Latrobe, Pa. The hacker pled guilty to four felony charges in juvie court. Reports say he got access to the site's servers and let loose a virus that brought everything down.
