A Reddit user reported that an employee triggered a Defender alert after installing the latest version of RVTools, which turned out to be a trojanized installer delivering the Bumblebee loader via a malicious DLL. VirusTotal detected the threat, the hash did not match, and the vendor's site briefly went down before silently uploading a clean version. The user documented the timeline, analysis, and response to the incident in a detailed report.
