Doubt over N Korea links to Sony attack

A senior FBI official has said that the agency has not confirmed widely held suspicions that North Korea is behind the unprecedented cyber attack on Sony’s Hollywood studio.

“There is no attribution to North Korea at this point,” Joe Demarest, assistant director with the FBI’s cyber division, said while speaking on a panel at a cyber-security conference sponsored by Bloomberg Government.

The comment casts at least some doubt on the widely held belief that North Korea has definitely been determined to be the culprit in the massive attack on the Hollywood studio, leaving room for other theories to emerge.
