Elite US litigation firm Boies Schiller & Flexner has been instructed by Sony Pictures Entertainment (SPE) to send warning letters to US news outlets as the studio seeks to limit the damage caused by a computer hack of its internal systems last month.

David Boies (pictured), the firm’s high-profile founder, chairman has sent letters to general counsel at the New York Times, The Hollywood Reporter, technology website Re/code and Gawker, stating that the company does not consent to any media outlet’s “possession, review, copying, dissemination, publication, uploading, downloading, or making any use of [stolen information]“.
