WASHINGTON, Dec. 26 (UPI) -- The hacker group Lizard Squad is claiming responsibility for a hack of Sony and PlayStation's online gaming services that shut down on Christmas Day.
The group, which had a well-publicized attack earlier in the month, took to Twitter to draw attention to its exploits.

The group taunted gamers from its Twitter account as they went into "Call of Duty" withdrawal.
The gaming services supposedly returned thanks to Megaupload founder Kim Dotcom, who offered the Lizard Squad 3,000 premium lifetime vouchers for his relaunched MegaPrivacy service.
Dotcom is wanted by the U.S. government for copyright infringement related to his file-sharing website. He took the time to take a dig at the United States with his example of diplomatic outreach.
