Unfortunately, the same open-source tools that help security teams prioritize risk and enhance security outcomes can be misused by threat actors for nefarious purposes.
For example, Rapid7 researchers are aware that the digital forensics and incident response (DFIR) tool Velociraptor has been observed being leveraged by threat actors to execute a ransomware campaign. Rapid7 has implemented detections for this and other Velociraptor-related misuse, and is not impacted by this incident.
