North Korea is suspected of the recent Sony Pictures hacking that leaked unreleased movies online including Brad Pitt's "Fury" and the 2014 "Annie." However, country officials refused to even deny their involvement and instead told US officials to just "wait and see."

A cyber-attack by a group called the "Guardians of Peace" crippled Sony servers and hacked into Sony Pictures movie database. According to RT, the massive leak of unreleased movies happened on Nov. 24, when studio employees noticed on their computer screens an image of a skeleton accompanied with the message "Hacked by #GOP." The group allegedly threatened to reveal "secrets and top secrets" of Sony. The FBI started on their investigation with an analysis on GOP's message. The message reportedly originated from a Chinese IP address, its format showing similarities to Chinese and Korean characters. While the group's identity still remains a mystery, speculations point to the hackers coming from North Korea.

According to The Business Insider, North Korea has a motive that links the country to the Sony Pictures hacking. The studio is set to release "The Interview," a comedy about the assassination of North Korean dictator Kim Jong-un. The country wasn't really in favour of the movie being released from the beginning.

According to the site on June 25, the country's official news agency previously criticised the film as a "blatant act of terrorism and war." Then on July 11 North Korean UN ambassador Ja Song-Nam called "The Interview" an "act of war and per Mirror UK the envoy even made threats of a "merciless response" if the film was not cancelled. Of course, Sony paid no heed and continued to promote the movie. Additionally, it's supposedly likely for North Korea being the culprit in the hacking. According to The Business Insider the country has its own hacking army division known as Unit 121 and has been linked to previous South Korea and U.S. cyber-attacks.

However, a representative for the North Korean government refused to deny their involvement in the Sony Pictures hacking. Instead, the spokesman released a cryptic message and told U.S. officials to just "wait and see." Likewise, an official from the country's London embassy reportedly also refused to comment on the speculations and said "they were not interested" in speaking to the press.

Sky News claims Sony Pictures has restored some of its important services following the hack. The company continues to work closely with law enforcements in the ongoing investigation. According to the site the massive hack of the studio's unreleased movies was described by cybersecurity experts as "the first of its kind on a major U.S. company."
