On Monday, employees at Sony Pictures Entertainment—the television and movie subsidiary of Sony Corp.—discovered that their internal corporate network had been hijacked. A message from an individual or group claiming responsibility appeared on corporate systems, pledging to release sensitive corporate data taken from the network by 11pm GMT on Monday.
Twitter accounts associated with promoting several movies, including Starship Troopers, were briefly hijacked by the attackers. The attackers posted to at least three Twitter feeds, leaving the same message: “You, the criminals including [Sony Pictures CEO] Michael Lynton will surely go to hell. Nobody can help you.” The image posted with the message shows a digitally edited image of Lynton’s head in a dark, hellish landscape.
As of this morning, the network at many Sony offices still appears to be down. Based on information reportedly shared by employees, it could be down for weeks before being restored. The Twitter accounts appear to be back under Sony Pictures’ control.
