In another development in Sony cyber attack to oppose "The Interview," North Korea has once again denied any role in the scandal. The government of North Korea has proposed a joint investigation into this incident so that they can prove their innocence.

The foreign minister of North Korea has released a statement that there would be "grave consequences" if Washington is not ready for the joint probe and continue to accuse North Korea for the attack. "As the United States is spreading groundless allegations and slandering us, we propose a joint investigation with it into this incident," the North Korea foreign minister said in a statement obtained by The Guardian.

The statement has come as a retaliation of President Barack Obama's strong oppose of axing the release of "The Interview." President Obama has taken a strong stand against the hackers who are disrupting the peace in the country and boasted the morals of Sony by saying that cancelling the release of their $90 million project at last moment without consulting him in the fear of a terrorist attack "is a mistake."

Meanwhile, Sony has also retreated from their earlier statement and has now declared that only movie's Christmas release is cancelled and they have not at all bowed down in front of hackers. As per recent reports, Sony is still looking for different platforms to release the flick keeping in mind the 9/11 style attack threats they received from hackers if the movie is released on Christmas. Also, it has mentioned the fact the prime reason for cancelling the Christmas day release is that several theatre owners have refused to screen the movie in fear of a deadly attack.

Sony encountered a cyber-failure on Nov. 24 which led to various confidential data, important email exchanges and unfinished scripts leaking out. A hacking gang 'Guardians of Peace' has taken the sole responsibility of the attack and warned the Sony of dire consequences if they release their movie "The Interview." The movie is a satirical take on the assassination attempt on North Korean leader Kim Jong-un by to two U.S. TV journalists, played by Seth Rogen and James Franco. On Friday, the FBI named North Korea as the prime suspect to blame for the devastating cyber strike on Sony Pictures Entertainment.

In the wake of one of the major corporate hacking scandals, U.S.has reportedly called Japan, China, South Korea and Russia to join hands to combat such cyber-attacks. Japan and South Korea has reportedly agreed, but China has still not confirmed anything about the issue. What started with a release of a comedy movie is now gaining momentum as North Korea is even prepping up against a war with the U.S. Their government has a fear that the U.S. may invade their territory under the guise of human rights abuses, as told by ABC.
