“Today, employees across the Sony Pictures offices were greeted with a strange picture as they tried to login to their computers. Since this afternoon, computers at the company have been completely unresponsive, showing a glowering CGI skeleton, a series of URL addresses, and a threatening message from a hacker group that identifies itself as #GOP. Dozens of Sony Twitter accounts were also commandeered to tweet out similar messages, although Sony seems to have regained control of those accounts. Early reports from Sony employees suggest the studio has yet to regain computer access.”
