Some cybersecurity experts say they’ve found striking similarities between the code used in the hack of Sony Pictures Entertainment and attacks blamed on North Korea which targeted South Korean companies last year. Sony has not commented on any Korean connection, except to deny a report Wednesday, Dec. 3, 2014 that it was poised to announce such a link. But three independent researchers told The Associated Press there are intriguing signs of a North Korean link to the attack, even as others warned it’s difficult to make a definitive connection.

Sony Pictures Entertainment was trying to stop downloads of its documents stolen in a massive hack at the film and television studio late last month, technology news website Re/code reported, citing two people familiar with the matter.

The company was using a denial-of-service attack through hundreds of computers in Asia to cripple the sites where its documents are available, the report said.

One of the sources told Re/Code Sony was using Inc's cloud computing services.

Sony Pictures Entertainment and Amazon were not immediately available for comment.

Hackers released sensitive data over the Internet, including employee salaries, social security numbers and high-quality digital versions of several unreleased films.

A group calling itself Guardians of Peace claimed responsibility for the cyber attack that shut down most of the studio's network for more than a week.
