U.S. officials believe the North Korean government
was behind the computer hacking attack on Sony Pictures Entertainment, a
massive security breach that embarrassed several executives and led to the
cancellation of the planned Dec. 25 release of "The Interview."
The officials told NBC News the hacking attack
originated outside North Korea, but they believe the individuals behind it were
acting on orders from the North Koreans.
"We have found linkage to the North Korean
government," according to a U.S. government source.
