The Uncertain Connection Between North Korea and Hackers

The recent release of The Interview could have been a movie unto itself (possibly a better movie), involving hackers, a secretive foreign nation, an inept corporation and the United States government. After the Sony leaks, the FBI said North Korean hackers were to blame, and Obama put sanctions into place in response. FOREIGN POLICY was affected by this cyberattack!! But was North Korea really the one responsible? And if it wasn't behind the leak, and we can't identify our attackers, what the heck does that mean for the 21st century?!!
