The government of North Korea denied its involvement in the hacking of Sony Pictures Entertainment and accused the United States of being hostile and repressive after the latter decided to implement new sanctions.

An unnamed spokesman for the Foreign Ministry of North Korea spoke to the KCNA news agency and continued to deny that Democratic People's Republic of Korea had something to do with the cyber attack.

"The persistent and unilateral action taken by the White House to slap sanctions against the DPRK patently proves that it is still not away from inveterate repugnancy and hostility toward the North," the spokesman stated.

The government of North Korea called the accusations as "groundlessly stirring up bad blood" and an attempt to isolate the country in the international community.

They also claimed that they offered the White House a chance for a joint investigation, which was ignored, and was likely a sign of the Washington's "guilty conscience." As such, they are strengthening their resolve of a military-first policy.

"It would only harden its will and resolution to defend the sovereignty of the country," the spokesman also stated.

After the cyber attack that hit Sony last month, President of the U.S. Barack Obama decided to impose sanctions against several North Korean officials and government agencies, particularly 10 officials, three state-run organizations, an arms exporter, its intelligence agency and a defense procurement agency.

The White House stated that the action was due to the "provocative, destabilizing and repressive actions and policies" of the country, "particularly its destructive and coercive cyber attack on Sony Pictures Entertainment."

While North Korea continued to deny its involvement in the hacking, it was noted that they previously called Sony's comedy film 'The Interview' an "act of war," and also praised the attack, calling it a "righteous deed," according to The Verge.
