Kaseya releases patch and restores services following REvil ransomware attack
SHARE
Kaseya Ltd. has released a patch and restored services some 10 days after its software was targeted by the REvil ransomware gang.
A patch has been released for Kaseya VSA On-Premises customers and has been deployed to VSA software-as-a-service infrastructure. The VSA 9.5.7a (9.5.7.2994) update fixes three zero-day vulnerabilities, those heretofore undiscovered, that were used in the REvil ransomware attacks.
On its rolling updates, Kaseya said this morning that SaaS customers were now back up and running, although the service suffered issues during the day. As of an update at 12:15 p.m. EDT, “unplanned maintenance” resulting in downtime occurred. Kaseya said the maintenance was the result of a “large number of users coming back online in a short window,” resulting in some performance issues.
