Hackers have plundered the personal details of world leaders, Hollywood A-listers and billionaire tycoons in a massive ‘virtual heist’ on exclusive jewellery firm Graff, The Mail on Sunday can reveal.

The cyber criminals have already leaked 69,000 confidential documents on to the so-called ‘dark web’, including files relating to Donald Trump, Oprah Winfrey, David Beckham and Sir Philip Green.

And they are thought to be demanding tens of millions of pounds in ransom money to stop the release of further sensitive information.

The notorious Russian hacking gang Conti is behind the data theft and claims the information published, involving about 11,000 of Graff’s well-heeled clients, represents just one per cent of the files it stole.

Documents including client lists, invoices, receipts and credit notes have been taken, and could prove embarrassing for customers who may, for example, have bought gifts for secret lovers or taken jewellery as bribes.
