North Korea was responsible for a “destructive” cyber attack on Sony Pictures, the US Federal Bureau of Investigation said December 19, 2014, warning it would hunt down the perpetrators and make them pay. “Such acts of intimidation fall outside the bounds of acceptable state behavior,” the FBI said in a statement, adding it would “identify, pursue, and impose costs and consequences on individuals, groups, or nation states who use cyber means to threaten the United States or US interests.” The attack prompted the movie giant to cancel the Christmas Day release of “The Interview,” a madcap satire about a fictional CIA plot to kill North Korean leader Kim Jong-Un.
