Hackers demand $70 million to end biggest ransomware attack on record

Cybersecurity teams are working feverishly to stem the impact of the single biggest global ransomware attack on record, with some details emerging about how the Russia-linked gang behind it breached the company whose software was the conduit.

An affiliate of the notorious REvil gang, best known for extorting $11 million from the meat-processor JBS after a Memorial Day attack, infected thousands of victims in at least 17 countries on Friday, largely through firms that remotely manage IT infrastructure for multiple customers, cybersecurity researchers said. REvil was demanding ransoms of up to $5 million, the researchers said. But late Sunday it offered in a posting on its dark web site a universal decryptor software key that would unscramble all affected machines in exchange for $70 million in cryptocurrency.
