Hackers who broke into the News Corporation network and forced its British websites offline claim to have stolen sensitive data from the company including emails and usernames/passwords.

All of News Corporation's British websites were taken offline today following an attack on the website of tabloid The Sun, which earlier today was redirecting to a fake story about Rupert Murdoch's death.

Further pain is expected for the media mogul as the hacker group responsible for the attack claims to have also stolen emails and passwords for News International executives and journalists. It said it would release more information tomorrow.

Websites for The Sun, The Times, BSkyB and News International were all inaccessible this morning.
