North Korea says that the cyber attack on Sony's Hollywood studio may have been the country's supporters but not the country itself. "The hacking into Sony Pictures Entertainment might be a righteous deed of the supporters and sympathizers with the DPRK in response to its appeal," an article by the KCNA news agency said, using the official DPRK acronym for North Korea.

"We do not know where in America the SONY Pictures is situated and for what wrongdoings it became the target of the attack nor we feel the need to know about it. But what we clearly know is that the SONY Pictures is the very one which was going to produce a film abetting a terrorist act while hurting the dignity of the supreme leadership of the DPRK by taking advantage of the hostile policy of the U.S. administration towards the DPRK," said the spokesman for the Policy Department of the National Defence Commission (NDC) of the DPRK Sunday.

It also warned the United States that "there are a great number of supporters and sympathizers with the DPRK all over the world."

A North Korean diplomat has also denied Pyongyang was behind the attack that was launched last month, though a U.S. national security source said it was a suspect.

The attack against Sony shut down most of the studio's network for more than a week and hackers have released sensitive data over the Internet, including employee salaries and Social Security numbers along with high-quality digital versions of several unreleased films.

Forensics experts hired by Sony said the breach was unprecedented, well-planned and carried out by an "organized group," according to a Reuters on Saturday.
