Sony through its Lawyer David Boies, has warned twitter to stop disseminating Sony hacked materials on its social network, Motherboard report.

The letter sent from David Boies, the lawyer Sony has hired to help guide it through the aftermath of the hack, to Vijaya Gadde, Twitter’s general counsel—says that if “stolen information continues to be disseminated by Twitter in any manner,” Sony will “hold Twitter responsible for any damage or loss arising from such use or dissemination by Twitter.”

A spokesperson for Twitter confirmed that the letter is authentic but declined to specifically comment about the company’s response. When asked whether the company would be deleting Broeksmit’s tweets, the spokesperson noted that, right now, the tweets are still live on the site.

In addition to holding Twitter responsible for dissemination of stolen Sony property, the company also demanded that Twitter “comply with all future requests with regard to any other account holder seeking to disseminate the Stolen Information via Twitter. In addition, we ask that you provide the Account Holder with a copy of this letter, and request that the account holder cease publication of the stolen information on Twitter.”
