A lawyer representing Sony Pictures Entertainment is warning news organizations not to publish details of company files leaked by hackers.
The Sony material includes studio financial records, employment files and what already has been revealed as salacious gossip by Hollywood executives about President Barack Obama and some of the industry's big stars and upcoming films.
Attorney David Boies (BOYZ) demanded Sunday that Sony's "stolen information" should be returned immediately because it contains privileged, private information.
Boies hinted at legal action if organizations "used or disseminated" the material "in any manner." The New York Times, the Hollywood Reporter and website Gawker were among those that received letters.
Sensitive material from the Sony hack is being leaked almost daily, including email exchanges and an early screenplay.
