On July 2 at 2:00 pm EDT, Kaseya, a developer of IT solutions for MSPs and corporate customers, announced that it was hit by a ransomware attack that exploited a vulnerability in its VSA software against several MSP (managed service providers) and their customers.

Since more than 40,000 organizations use at least one Kaseya software, the company has notified its customers of the breach, while urging them to immediately shut down their VSA servers.

While Kaseya also shut down its SaaS servers and pulled its data centers offline as the company’s incident response team investigated the crisis, the company called itself the “victim of a sophisticated cyberattack” by July 4 after investigating the severity of the attack.

While the FBI described the incident as a “supply chain ransomware attack leveraging a vulnerability in Kaseya VSA software against multiple MSPs and their customers,” Huntress Labs, a security firm, tracked 30 MSPs involved in the breach, explaining that the attack was triggered by a vulnerability to bypass authentication in the Kaseya VSA web interface.
