Was North Korea behind the Sony hack?

The final shot of Kim Jong Un before he dies a fiery death in "The Interview"

While the U.S. government's claimed that North Korea is behind the Sony hack, some cybersecurity experts aren't as convinced.

2014 was NOT a fabulous year for Hollywood. The box office grand total for the year came in at 10.3 BILLION bucks, which is down about five percent from 2013. Analysts blame all sorts of things... a lackluster line-up over the summer, the distraction of the World Cup, the Fourth of July falling on a Friday! But there was one film which fared quite well, considering it never hit major movie theaters.

Sony's "The Interview."

The studio initially said it wouldn't release the film at all after a massive data breach and threats against those who dared to see it. There is still a lot of speculation about who exactly broke into Sony's computer network. Federal authorities insist North Korea was behind the attack, but cybersecurity experts are not as convinced.
