Sony Pictures Entertainment, which was the subject of a data leak following a hack, saved thousands of company passwords in a folder called 'passwords', it has emerged.
It forms part of a host of folders which have been posted online that also contain the personal details - including social security numbers - of 47,000 employees, including Hollywood stars Sylvester Stallone and Judd Apatow.
Sony Pictures was hacked at the end of last month, with the company's internal IT systems taken offline by a group calling themselves the Guardians of Peace, or GOP, with some claiming they had links to North Korea.
The attack was said to be in retaliation to the new James Franco and Seth Rogen movie where the two play journalists tasked with assassinating North Korean leader Kim Jong-Un. Both actors' salaries for the movie have also been leaked.
In a letter to the United Nations, North Korea called the film an "act of war", and when asked by the BBC if the country had anything to do with the attack, a government spokesman replied "wait and see".
Since the attack, company details, as well as prominent and forthcoming movies including Brad Pitt's Fury have been leaked online in high quality, suggesting they may have been stolen in the breach. Four of the company's films not yet released are among those to have appeared on pirate sites.
