The Kaseya Attack

Microsoft Exchange Hack

The REvil gang has pulled off one of the biggest ransomware heists in years, exploiting a vulnerability in Kaseya’s on-premise VSA remote monitoring and management tool to compromise nearly 60 MSPs and encrypt the data and demand ransom payments from up to 1,500 of their end user customers.

Kaseya said the cybercriminals were able to exploit vulnerabilities in its VSA tool to pass authentication and run arbitrary command execution. This allowed REvil to leverage the VSA product's standard functionality and deploy ransomware to customer endpoints.

The cyberattack left more than 36,000 MSPs without access to Kaseya's flagship VSA product for at least four days as the company worked on a patch for the on-premises version of VSA and kept the more widely-used SaaS version of VSA offline as a precautionary measure.
