(CNN) - A virtual terror attack with very real repercussions for U.S. national security.
Today, the Obama administration wouldn't say just who is responsible for the massive cyberattack of Sony pictures. But the government is getting closer and closer to confirming what CNN reported last night, with unnamed U.S. officials fingering North Korean hackers as the culprits.
What we know so far is a group called "Guardians of Peace" raided Sony's network in November over the movie "The Interview," a not-so-gentle satire depicting an assassination plot against North Korean dictator Kim Jong Un.
Then this week, the plot thickened and the hack morphed into a terror threat when that group referenced 9/11 and issued a warning to would-be-moviegoers to stay away from theaters set to show the flick. Sony announced this morning its scrapping any plan to release the film at all.
Hollywood seems to be quite fearful. Some theaters planned to show in place of "The Interview" the 2004 film "Team America: World Police," which spoofs Kim Jong Un's father Kim Jong II. But Paramount Pictures has put a stop to that as well, today telling theaters not to run this ten year old movie, as first reported by Gizmodo.
And this afternoon, White House Press Secretary Josh Earnest called the situation "a serious national security matter" and blamed an unnamed "sophisticated actor."
But even before the Obama administration officially blames North Korea - country where most people probably don't know what the internet is - others are already saying the U.S. has lost its first battle in the cyber war.
