The REvil ransomware group claims to have buyers ready for documents containing damaging information about President Donald Trump and is preparing to auction data on international celebrity Madonna. The hackers breached the network of Grubman Shire Meiselas & Sacks (GSMLaw), a law firm representing a huge number of A-list celebrities, stealing everything they considered of value before encrypting the data. The ransom for decrypting the files, initially set at $21 million, was not paid and the hackers threatened to publish what they had pilfered.
