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, has data that doubts some of the FBI’s findings.

Stop-Wasting-Money-On-Print“Sony was not just hacked, this is a company that was essentially nuked from the inside,” said Stammberger.

“I think we definitely jumped the gun,” David Kennedy, CEO of information security firm TrustedSec,ย stated on Friday. “A lot of [the evidence is] very circumstantial.”

Other experts in cybersecurity and private intelligence are also questioning the FBI’s claim that North Korea is solely to blame for the Sony hack.

“There are certainly North Korean fingerprints on this but when we run all those leads to ground they turn out to be decoys or red herrings,” said Stammberger.
