A U.S. government source said investigators had determined North Korea was behind a cyberattack on Sony Pictures as the studio pulled all plans to release its comedy, "The Interview," about an assassination attempt on the North Korean leader.
Hackers who said they were incensed by the film attacked Sony Corp. last month, leaking documents that drew global headlines. They have now forced an apparently unprecedented change of plans for a major movie release.
Washington may officially announce soon that the North Korean government was behind the attack, the U.S. government source said.
