"The actions taken today under the authority of the President's new Executive Order will further isolate key North Korean entities and disrupt the activities of close to a dozen critical North Korean operatives," US Treasury Secretary Jack Lew said. "We will continue to use this broad and powerful tool to expose the activities of North Korean government officials and entities."
The newly imposed restrictions target the Reconnaissance General Bureau (RGB), North Korea's primary intelligence organization; Korea Mining Development Trading Corporation (KOMID), North Korea's primary arms dealer; and the Korea Tangun Trading Corporation, which procures commodities and technology for North Korea's defense research and development.
The sanctions also target ten individuals from the three entities, as well as officials of the government of North Korea. Among them are several KOMID-linked individuals in China, Russia, Syria, Iran and Southern Africa.
The FBI identified North Korea behind the November 24 cyber-attack at Sony, in which the hacking group Guardians of Peace released confidential documents and emails causing an embarrassment to the filmmaker.
After Sony initially bowed to the hacker's demands not to show the film, the entertainment giant reversed course and showed the film at select theaters for the Christmas Day opening. It also allowed viewers to watch the film online. North Korea has denied involvement in the hacking and several cyber security experts in the US have questioned drawing a quick conclusion North Korea was behind the attack.
