Experts suggest the Sony hack may have been an inside job

Was “The Interview” the perfect cover? The Federal Bureau of Investigation conducted an extensive investigation into the recent massive Sony hack. Following the conclusion of that investigation, the FBI felt that its evidence pointing to hackers with ties to North Korea was so strong that President Obama publicly pinned responsibility on the Eastern nation.

Cybersecurity experts are questioning the FBI’s claim that North Korea is responsible for the hack that crippled Sony Pictures. Kurt Stammberger, a senior vice president with cybersecurity firm Norse, told CBS News his company has data that doubts some of the FBI’s findings. “Sony was not just hacked, this is a company that was essentially nuked from the inside,” said Stammberger. While Norse is not involved in the Sony case, it has done its own investigation. “We are very confident that this was not an attack master-minded by North Korea and that insiders were key to the implementation of one of the most devastating attacks in history,” said Stammberger.
