Tenable has disabled two Nessus scanner agent versions (10.8.0 and 10.8.1) after discovering a critical issue where a faulty differential plugin update was causing agents to go offline. This issue impacts the Nessus agents ability to scan for vulnerabilities and collect security data. Tenable has released version 10.8.2 to fix this problem and has provided instructions on how to bring the affected agents back online. This is a critical update for all users of the Tenable Nessus Agent.
