The hacking group LulzSec appears to be back, with a very timely hack of Rupert Murdoch's British tabloid The Sun—the sister publication of the dead News of the World. And they warn, ominously, that they've got emails, too.

The front page website of The Sun was briefly redirected to a hacked Times of London site (also owned by Murdoch's News International), which was defaced with a fake story about Rupert Murdoch being found dead in his garden. Now, the site is redirecting to LulzSec's twitter account.

But more enticing to anyone following the News International hacking scandal is a hint from a LulzSec leader named Sabu, that "we're sitting on their emails." Sabu has already tweeted what he claims are the email addresses and passwords of Sun staff, including former News International chief Rebekah Brooks, and former Sun managing editor Bill Akass.
