US Said to Find North Korea Ordered Cyberattack on Sony

American officials have concluded that North Korea was “centrally involved” in the hacking of Sony Pictures computers, even as the studio canceled the release of a far-fetched comedy about the assassination of the North’s leader that is believed to have led to the cyberattack.

Senior administration officials, who would not speak on the record about the intelligence findings, said the White House was debating whether to publicly accuse North Korea of what amounts to a cyberterrorism attack. Sony capitulated after the hackers threatened additional attacks, perhaps on theaters themselves, if the movie, “The Interview,” was released. Officials said it was not clear how the White House would respond.
