US Investigators Pin Sony Hack on North Korea Multiple reports says US is ready to blame Pyongyang By John Johnson, Newser Staff Posted Dec 17, 2014 6:01 PM CST 42 comments Comments This image released by Columbia Pictures shows James Franco, left, and Seth Rogen in "The Interview." (AP Photo/Columbia Pictures, Sony, Ed Araquel) (Newser) – It was North Korea. Or at least that's what federal investigators looking into the massive hack of Sony Pictures have concluded, reports NBC News. The AP and CNN have the same scoop, with the latter saying that a formal announcement could come tomorrow. All of the reports are based on anonymous sources, and none of them offer specifics on what happened. "We have found linkage to the North Korean government," one official tells NBC. The hackers reportedly launched the attack from outside North Korea but were acting at the behest of Pyongyang. The development comes just after Sony announced it was canceling the Christmas Day release of The Interview, whose plot centers on an assassination attempt of the North Korean leader.
