The hacker group known as Lulz Security took over the website of The Sun tabloid, writing a fake story saying that Rupert Murdoch, the paper's owner, had been found dead in his garden. Users were then directed to the hacker group's Twitter feed. Lulz Security took responsibility on Twitter, saying it was a successful "Murdoch Meltdown Monday."

The hacker group has previously targeted Sony, Nintendo and even the CIA.

Meanwhile, the News of the World scandal continued to expand Monday with the rapid resignations of two top officers with London's police force, amid claims of possible eavesdropping, bribery and collusion. Even the prime minister has been feeling the heat on the scandal, as he cut short a trip to Africa and called an emergency session of Parliament for Wednesday so he could speak on the matter.

On Tuesday, UK lawmakers will grill Murdoch, his son James, and ousted chief executive Rebekah Brooks in a televised public hearing where it is expected they will demand to know how much executives knew about the alleged phone-hacking practices of their employees.

Monday also saw the death of one of the first whistleblowers in the tabloid scandal that has engulfed the British parliament, Scotland Yard and Murdoch's News Corp. empire. Police have said the death is not considered suspicious.

Sean Hoare, who alleged widespread hacking at the now-defunct News of the World, was found dead at his English home. He was quoted in the New York Times saying that breaking into the voice mail of celebrities, politicians, other journalists and even murder victims was encouraged under the leadership of then-editor Andy Coulson.

Coulson - who was recently employed as British Prime Minister David Cameron's communications chief - has since been arrested in the widening scandal.

Scotland Yard is increasingly facing its own internal crisis in relation to the phone-hacking crisis and is also under pressure to explain why its original hacking investigation only led to the prosecution of a single reporter and a private investigator.

It was Assistant Commissioner John Yates - Scotland Yard's top anti-terrorist officer - who decided two years ago to not reopen a police inquiry into the phone-hacking allegations. But when detectives reopened the investigation this year they said they found the names of 3,700 potential hacking victims.

A total of 10 people have since been arrested in connection to the case.
