Comey is misspelled as Corney in a Wikileak where he blamed North Korea for hacking Sony. Corney claimed to quickly know it was NK due to a mistake that allowed their IP to be traced (think Vault 7):

Hackers who targeted Sony Pictures over the release of the film The Interview “got sloppy” and inadvertently revealed their links to North Korea, according to the director of the FBI.Speaking at the International Conference on Cyber Security James Comey said hackers had mistakenly sent messages that could be traced to IP addresses used exclusively by North Korea. Corney said the North Korean origins of the cyber attack were evident despite the use of proxy servers in other countries to throw investigators off their trail. "It was a mistake by them," he said. "It made it very clear who was doing this."
