Hack to reveal showbiz trove

THE world’s most powerful A-list legal firm hit by a cyberattack is refusing to pay the shadowy hackers their $42 million ransom demand — meaning that a trove of details of some of the biggest deals in showbiz history, including Bruce Springsteen’s Netflix deal and Diddy’s rumored $100 million vodka deal will be laid bare on the Internet.

The Secret Service and the FBI are continuing to probe hacking group REvil, which attacked the server of attorney Allen Grubman’s NYC firm and stole 756 gigabytes of confidential documents relating to clients including Lady Gaga, Madonna, Mariah Carey, Priyanka Chopra and Bette Midler.

On Thursday, the hackers upped the ante by doubling their ransom demands and threatening to publish “a ton of dirty laundry” on President Donald Trump, who is not a client of the firm Grubman Shire Meiselas & Sacks. The firm was offered one week to pay the ransom in full. It remains unclear if the hackers’ claims to have dirt on Trump are true.

A source with knowledge of the hack told Page Six, “Grubman isn’t going to pay these cyberterrorists a penny, so it is likely all his files will end up released by the hackers. The interesting details in there could include U2’s lucrative publishing deals with Universal, worth an estimated $300 million, as well as

Springsteen’s deal with Netflix, estimated to be worth $20 million, and how much Diddy actually made in that Cîroc vodka deal.” The source added, “Often, the most damaging details are in the personal e-mails of the stars and the executives — which is what happened with the 2014 Sony hack. But it is not known how many personal e-mails have been stolen [by] the Grubman hackers.” The hackers have not specifically threatened to reveal details on those particular stars or their deals.

On Thursday, REvil posted a host of documents relating to Lady Gaga on its site on the dark Web, but most appeared to be standard industry contracts.
