London: Social network Facebook has hired a computer hacker who was recently sued by Sony for hacking the online game system PlayStation 3.
Facebook, however, did not reveal what 21-year-old George Hotz will do for the firm.
Hotz - also known by the alias "GeoHot" - gained notoriety in 2008 when he developed a software for unlocking the iPhone and allowing it to be used by other networks, the report said.
He also released instructions on Sony PlayStation 3 that helped owners modify their consoles to run unauthorised applications and pirated games.
After Sony sued Hotz, hacker group Anonymous retaliated by bombarding the firm`s servers.
They also broke into Sony`s systems and stole personal information from online accounts of 100 million customers.
