Scale, details of massive Kaseya ransomware attack emerge

A broad array of businesses and public agencies were hit by the latest attack, apparently on all continents, including in financial services, travel and leisure and the public sector.

Cybersecurity teams worked feverishly on Sunday to stem the impact of the single biggest global ransomware attack on record, with some details emerging about how the Russia-linked gang responsible 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. They reported ransom demands of up to $5 million. The FBI said in a statement on Sunday that it was investigating the attack along with the federal Cybersecurity and Infrastructure Security Agency, though “the scale of this incident may make it so that we are unable to respond to each victim individually.”
