Kaseya Supply-Chain Attack Leads to Ransomware 

THE THREAT

Time Sensitive: All Kaseya VSA clients need to immediately shut down their VSA Servers. This afternoon on July 2nd, 2021, it was discovered that the Kaseya VSA remote monitoring and management platform is being abused by cybercriminals in order to deliver the REvil (Sodinokibi) ransomware via an auto-update.

This ransomware campaign is ongoing at the time of writing. Until further details are released, again all organizations using Kaseya need to immediately shut down their VSA servers. The number of Kaseya clients impacted is still being assessed, but it is being reported that both cloud and on-premise customers are affected.

What you should do about it

Additional information

As this campaign is still occurring, details are currently limited. Huntress Labs has stated that at least 200 different organizations have been identified as impacted so far. According to security researcher Kevin Beaumont, the ransomware is delivered via an automated software update in Kaseya. Once on the system, the ransomware actors stop administrator access to the VSA platform and proceed to drop malicious files on the client system. Microsoft Defender is disabled or modified to prevent real-time monitoring. By design, Kaseya has wide-reaching access, meaning the REvil ransomware can be widely deployed at a rapid pace.

It appears that Kaseya has temporarily disabled their Cloud offering. As such, immediate action is required by users of on-premise installations of Kaseya to prevent the deployment of ransomware.
