While the origins of the Sony hack is still a point of contention, with some people claiming it was a company insider named Linda and many claiming it was North Korea, President Obama has put up new sanctions against three North Korean organizations as well as 10 individuals.

These sanctions, according to the BBC,  are believed to be the first time the U.S. has punished a country over cyber-attacks against a company based in the U.S.

While all the new sanctions are believed to not be against those directly involved with the Sony hack, White House officials are saying the sanctions are meant to isolate North Korea’s defense industry to prevent future cyber-attacks.

“This is really an example of where you’ve had a country really cross a threshold in terms of its attack due to its destructive and coercive nature,” said an official according to Politico.

The sanctions are mostly centered on North Korea’s military intelligence agencies, while the 10 individuals who are affected by the sanctions are, according to Reuters, involved in the sale and proliferation of weapons.

In a letter written by President Obama to House Speaker John Boehner and Senate Majority Leader Mitch McConnell, the president wrote, according to ABC News, “The order is not targeted at the people of North Korea, but rather is aimed at the Government of North Korea and its activities that threaten the United States and others.”

Whether or not these sanctions will have the desired results the White House hopes for is still unknown. However, given the U.S. placed sanctions on North Korea’s nuclear program in 2008, 2010, and 2011, all of which North Korea ignored, one can assume these sanctions will not be taken seriously by the government of North Korea.
