Nearly three weeks after Florida-based software vendor Kaseya was hit by a  widespread supply-chain ransomware attack , the company on Thursday said it obtained a universal decryptor to unlock systems and help customers recover their data. "On July 21, Kaseya obtained a decryptor for victims of the REvil ransomware attack, and we're working to remediate customers impacted by the incident," the company  said  in a statement. "Kaseya obtained the tool from a third-party and have teams actively helping customers affected by the ransomware to restore their environments, with no reports of any problem or issues associated with the decryptor."

It's not immediately clear what prompted the infrastructure to be knocked offline. REvil is one of the most prolific ransomware-as-a-service (RaaS) groups that first appeared on the threat landscape in April 2019. It's an evolution of the  GandCrab  ransomware, which hit the underground markets in early 2018. "If REvil has been permanently disrupted, it'll mark the end of a group which ha

Threat actors behind the notorious REvil cybercrime operation appear to have pushed ransomware via an update for Kaseya's IT management software, hitting around 40 customers worldwide, in what's an instance of a widespread supply-chain ransomware attack. "Beginning around mid-day (EST/US) on Friday, July 2, 2021, Kaseya's Incident Response team learned of a potential security incident involving our VSA software," the company's CEO Fred Voccola  said  in a statement shared late Friday. Following the incident, the IT and security management services company said it took immediate steps to shut down its SaaS servers as a precautionary measure, in addition to notifying its on-premises customers to shut down their VSA servers to prevent them from being compromised. Voccola also said the company has identified the source of the vulnerability and that it's readying a patch to mitigate the ongoing issues. In the interim, the company also noted it intends to
