Kaseya Using Universal Key to Unlock REvil-Encrypted Customer Data

Kaseya announced this week that it is using a “universal decryptor key” for customers that were affected by a REvil ransomware attack reported on July 2.

The REvil ransomware-as-a-service group had encrypted Kaseya’s customers’ data, promising to unlock it for a price. They carried out the attacks by leveraging a zero-day vulnerability in Kaseya’s VSA management solution. The attacks were described as potentially affecting about 60 of Kaseya’s managed service provider (MSP) customers plus almost 1,500 of their business customers.

In a July 22 notice, Kaseya indicated that it had obtained a universal decryptor key from “a third party,” which wasn’t named. The note added that there have been “no reports of any problem or issues associated with the decryptor.” Kaseya is currently contacting customers affected by the ransomware.

Kaseya’s announcement left it unclear whether the third party might be the REvil gang that had launched the ransomware or some more helpful entity.

Customers that had used Kaseya’s premises-installed VSA management solution were the ones affected by the REvil ransomware. Kaseya also offers VSA as a hosted service, but it apparently wasn’t affected. The company, which provides IT management solutions to MSPs and organizations, has since patched both VSA product implementations.




Kaseya is working with New Zealand-based Emsisoft to support affected customers. “Emsisoft has confirmed the key is effective at unlocking victims,” Kaseya’s announcement indicated.

The attack reportedly affected 800 of Sweden’s Coop grocery stores, which had be closed, according to Reuters. The ransomware had infiltrated Coop’s IT service provider, used to maintain its cash registers.

The REvil attackers had at one point demanded $70 million to restore all of the encrypted data.
