A massive REvil ransomware attack affects multiple managed service providers and over a thousand of their customers through a reported Kaseya supply-chain attack.
Starting this afternoon, the REvil ransomware gang, aka Sodinokibi, targeted MSPs with thousands of customers, through what appears to be a Kaseya VSA supply-chain attack.
BleepingComputer has been told by both Huntress' John Hammond and Sophos' Mark Loman that the attacks on MSPs appear to be a supply chain attack through Kaseya VSA. According to Hammond, Kaseya VSA will drop an agent.
A sample of the REvil ransomware used in one of these attacks has been shared with BleepingComputer.
According to Emsisoft CTO Fabian Wosar, MSP customers who were affected by the attack received a much smaller $44,999 ransom demand.
MSPs are a high-value target for ransomware gangs as they offer an easy channel to infecting many companies through a single breach, yet the attacks require intimate knowledge about MSPs and the software they use.
