WikiLeaks creates online archive of hacked Sony documents

Whistleblower site WikiLeaks has put hundreds of thousands of emails and documents from last year's Sony hack into a searchable online archive.

The website founded by Julian Assange says that its database includes more than 170,000 emails from Sony Pictures Entertainment and a subsidiary, plus more than 30,000 other documents.

In December, Sony suffered a crippling cyberattack ahead of the release of the movie "The Interview," set in North Korean. An unknown organization leaked the documents and other damaging information online, but not in an easily searchable database.

In a statement, Assange said the documents show the inner workings of an international company and therefore belongs in the public domain.

"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, a Sony spokesperson said in an emailed statement. "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."
