Many computer-security experts doubt the validity of the claim that North Korea is behind the Sony Pictures Entertainment hack, citing a lack of strong evidence and the possibility of alternate scenarios.
“There’s no direct, hard evidence that implicates North Korea,” Sean Sullivan, a security adviser at Finnish security firm F-Secure, told Tom’s Guide. “There is evidence of extortion (the Nov. 21 email [to Sony executives which demanded money]) and the hackers only mentioned [the movie] The Interview after it was brought up in the press, which they then used to their advantage.”
“There’s no evidence pointing to North Korea, not even the barest of hints,” Robert Graham, CEO of Atlanta-based Errata Security, told Tom’s Guide. “Some bit of code was compiled in Korea — but that’s South Korean (banned in North Korea, [which] uses Chinese settings). Sure, they used threats to cancel The Interview — but after the FBI said they might.”
