WASHINGTON, March 18 (UPI) -- A U.S. official said the December Internet blackout in North Korea was a retaliatory strike after a data breach at Sony Pictures disrupted employee computers and disclosed confidential Sony information to the public.
Bloomberg reported Rep. Michael McCaul, R-Texas, chairman of the House Homeland Security Committee, said a December attack on North Korean Internet was payback for the Sony hack, but the U.S. official declined to identify the agency responsible for the retaliation.
