According to CNN, NBC, and the New York Times, US officials will announce tomorrow that they've identified North Korea as the source behind a massive cyberattack against Sony Pictures. As a result of threats tied to the attack, Sony Pictures today cancelled the premiere of its upcoming movie The Interview. According to the sources, the government has decided North Korea was "centrally involved", even though the attack may have been launched using computers elsewhere, contrary to reports it may not have been related to that country at all. There's also no word on what, if any, response there will be to the attack. Sounds like a job for Simon.
