Sony’s lawyer David Boies has sent a letter to Twitter’s general counsel Vijaya Gadde seeking to ban all accounts linked to the hacking attack that targeted the company’s computer systems late last month.

In the letter, Boies stated that Sony would ‘hold Twitter responsible for any damage or loss arising’ from the use of the stolen confidential information.

Verge cited the letter, which read: "If Twitter does not comply with this request and the stolen information continues to be disseminated by Twitter in any manner, SPE will have no choice but to hold Twitter responsible for any damage or loss arising from such use or dissemination by Twitter."

Sony mainly targeted musician Val Broeksmit, who reportedly tweeted screenshots of Sony emails on his @BikiniRobotArmy account and also sought suspension of Broeksmit’s Twitter account and wipe out all the emails stored on its systems.

As part of the hack by the group, who call themselves the Guardians of Peace (GOP) leaked five of the yet to be released Sony films to DVD onto the internet.

Furthermore, security firm Symantec found that malware involved in the Sony hack is linked to earlier attacks in South Korea, with some media reports holding North Korean sympathisers responsible for the attack.
