(Reuters) - Sony Pictures Entertainment told certain news organizations on Sunday to stop publishing information contained in documents stolen by hackers who attacked the movie studio's computer network last month, three media groups reported.

The New York Times, The Hollywood Reporter and Variety published stories reporting that they had each received a letter from David Boies, an attorney for Sony, demanding that the outlets stop reporting information contained in the documents and immediately destroy them.

The studio "does not consent to your possession, review, copying, dissemination, publication, uploading, downloading or making any use" of the information, Boies wrote in the letter, according to the New York Times report.

A Sony spokesman had no comment on the reports. Representatives for Variety and The Hollywood Reporter could not immediately be reached via email on Sunday.

New York Times spokeswoman Eileen Murphy said: "Any decisions about whether or how to use any of the information will take into account both the significance of the news and the questions of how the information emerged and who has access to it."

A spokesman for Boies confirmed he sent a letter to certain media outlets on behalf of Sony but declined to discuss details.

Disclosures from the internal documents have caused turmoil at the studio, a unit of Japan's Sony Corp, and shed light on internal discussions key to the company's future.
