The U.S. investigation into the recent hacking attack at Sony Pictures Entertainment has turned up evidence that does not point to North Korea as the “sole entity” in the case, but rather, raises the possibility that Iran, China or Russia may have been involved, an intelligence source told Fox News on Thursday.

Earlier Thursday, Fox News confirmed that the FBI is pointing a digital finger at North Korea for the attack.

The source pointed to the sophistication of malware “modules or packets” that destroyed the Sony systems — on a level that has not been seen from North Korea in the past — but has been seen from Iran, China and Russia.
