WikiLeaks has published an archive of data it claims was obtained in last November’s attack on Sony Pictures Entertainment.
The cache is said to include some 30,287 documents and 173,132 emails to and from more than 2,200 email addresses related to the movie division, and includes an analysis and search system for the archive.
Julian Assange, founder of WikiLeaks, said: "This archive shows the inner workings of an influential multinational corporation.
"It is newsworthy and at the centre of a geo-political conflict. It belongs in the public domain. WikiLeaks will ensure it stays there."
At the time of the attack on Sony, carried out by those said to be upset with the company, many emails were leaked to the press, some containing embarrassing discussions about actors who had worked with the company.
Following the assault, Sony Pictures Entertainment co-chair Amy Pascal left her post, with the company also delaying its financial results as it recovered.
Commenting on the WikiLeaks release, a Sony spokesman said: "The attackers used the dissemination of stolen information to try to harm SPE and its employees, and now WikiLeaks regrettably is assisting them in that effort.
"We vehemently disagree with WikiLeaks’ assertion that this material belongs in the public domain and will continue to fight for the safety, security, and privacy of our company and its more than 6,000 employees."
