Sony Pictures Entertainment continues to attempt to fight back against the hackers leaking their sensitive material online.  CNN Money reports that the company has threatened legal action against Twitter if it does not block users sharing the material on its site.

Sony has been the victim of persistent hacking by a group that has been leaking information on the internet since November 24.  The information has included emails from top Sony leaders as well as private information about all levels of Sony employees.  Sony’s top attorney, David Boies, has written several letters to top news sources asking them to stop repeating and spreading the information gained by the hackers.  The letter to CNN declared that Sony does not consent to having the information, some of which it deemed threatening to its employees, be in the possession of the outlets.  It also requested cooperation in destroying the materials.

Boies’ letter to Twitter requested they suspend or block the accounts of anyone sharing copyrighted material, especially one user who uses the name @BikiniRobotParty.  Boies wrote that Sony “does not consent to Twitter’s or any Twitter account holder’s possession, review, copying, dissemination, publication, uploading, downloading, or making any use of the stolen information.”

The letter alleges that the information itself is against US law.  It also maintains that sharing the information violates Twitter’s user policies, which prohibit using the site to publish unlawful material, copyrighted material, and any material that contains private and confidential material.

Twitter has not responded formally to the letter.  @BikiniRobotParty’s account was still active as of Tuesday December 23.
