Hacking group LulzSec has claimed on Monday evening to have penetrated the News International internal network, tampering with the companies' newspaper web sites as well as obtaining staff details and login credentials.
On Monday evening, visitors to The Sun's website were redirected to a fake front page claiming that Rupert Murdoch had killed himself by eating palladium. Shortly afterwards, the page redirected to LulzSec's Twitter feed, and the sites of the Times and the Sunday Times went offline.
At the time of writing, all three websites remain offline.
LulzSec has also tweeted what it says are a variety of access details for staff members' email accounts at News International, including those of ex-CEO Rebekah Brooks.
