FBI continues to investigate cyber-attacks and threats to show Trump's "dirty laundry" by dark web hackers alleging bluff

The FBI investigation of the hacker attacks by dark web group REvil against Attorney Allen Grubman and promising to show Trump’s “dirty laundry” says there are no evidences that the hackers have anything to show and the threat is a trick.
Recall that the hackers stole 756 gigabytes of the confidential documents of Grubman’s clients, including Lady Gaga, Mariah Carey, Bette Midler and others, and deleted or encrypted the backup copies. Initially REvil demanded $21 million but later increased the number to $42 million.
However, Grubman denied negotiations. He said that the required ransom is one of the largest ever done.
The shadowy group went further and threatened to publish “a pile of dirty laundry” on the US President Donald Trump if they don’t get the demanded amount of money.
“The next person we'll be publishing is Donald Trump. There's an election race going on, and we found a ton of dirty laundry,” the group said in the post, without elaborating on what information they might have on the president.
One of the most important clues to the version that the hackers are bluffing is that Trump has never been Gubman’s client neither as an entrepreneur not during his administration, according to the sources.
But a number of Trump’s critics emerged from the woodwork to suggest that the information will be leaked.
Can we start a go fund me page to pay the ransom so the info goes public?

If these hackers actually have Trump’s dirty laundry, we should create a GoFundMe to raise the ransom money for their files. ???????????? https://t.co/IL3er3Hsjd
Some were more skeptical, however, arguing the whole operation is a “brilliant” ruse to persuade gullible “liberals” to shell out millions in order to “get the goods on Trump,” according to Russia Today.
Hackers are smart, they know liberals are not. Some idiots would actually set up a go fund me to get the goods on Trump. Meanwhile they got nothing, brilliant.

If hackers had got hold of Trump's secrets, they would send a few nice samples to the WaPo and the NYT as a teaser and raise the price for the rest.

Until I see that, this is not something I would read.
