Kaseya urges customers to immediately shut down VSA servers after ransomware attack

UPDATE: In a statement late Friday evening, Kaseya CEO Fred Voccola confirmed that the company’s Incident Response team caught wind of the attack mid-day and immediately shut down their SaaS servers as a precautionary measure, despite not having received any reports of compromise from any SaaS or hosted customers.

[We] immediately notified our on-premises customers via email, in-product notices, and phone to shut down their VSA servers to prevent them from being compromised. We then followed our established incident response process to determine the scope of the incident and the extent that our customers were affected, Voccola said.

We engaged our internal incident response team and leading industry experts in forensic investigations to help us determine the root cause of the issue. We notified law enforcement and government cybersecurity agencies, including the FBI and CISA. While our early indicators suggested that only a very small number of on-premises customers were affected, we took a conservative approach in shutting down the SaaS servers to ensure we protected our more than 36,000 customers to the best of our ability.

So far, the company said they believe their SaaS customers “were never at-risk” and expects to restore service to them in the next 24 hours once it is confirmed to be safe.

According to Voccola, about 40 customers worldwide were affected and the company is preparing a patch to mitigate the vulnerability for any on-premises victims.

We’ve heard from the vast majority of our customers that they experienced no issues at all, and I am grateful to our internal teams, outside experts, and industry partners who worked alongside of us to quickly bring this to a successful outcome, Voccola added.
