The Dutch Institute for Vulnerability Disclosure has revealed that the ransomware gang has exploited a zero-day vulnerability in its Kaseya VSA servers with the CVE-2021-30116.

Wietse Boonstra, a DIVD researcher, has previously identified a number of the zero-day vulnerabilities [CVE-2021-30116] which are currently being used in the ransomware attacks.

The number of Kaseya VSA instances that are reachable from the internet has dropped from over 2.200 to less than 140 in our last scan today. And, by working closely with our trusted partners and national CERTs, the number of servers in The Netherlands has dropped to zero.” reads the blog post.

while Kaseya was validating its patch before the rollout to its customers, the ransomware gangs seems to have taken the advantage of the vulnerability by the historic supply chain attack, which is considered to be the one of the largest cyber attack against a MSP organization.
