Security researchers have sounded the alarm after discovering that sophisticated threat actors are abusing Velociraptor, a popular DFIR (Digital Forensics and Incident Response) tool, to carry out persistent attacks within compromised systems. Originally designed for incident responders and security professionals, Velociraptor’s capabilities are now being repurposed by attackers to help them remain hidden and expand access after initial compromise.

How Attackers Are Misusing Velociraptor
The malicious use of Velociraptor is stealthy and clever. After deploying the tool on compromised machines, attackers leverage its features for:
- Persistence: Configuring Velociraptor to maintain access even after system reboots.
- Reconnaissance: Gathering system details, network topology, and privileged credentials.
- Privilege Escalation: Using Velociraptor’s internal mechanisms to gain higher-level access and move laterally within networks.
These capabilities, originally intended to help forensic investigators, now provide threat actors with a hidden toolkit under the guise of legitimate remote forensic software. Analysts warn that because Velociraptor is trusted and not typically flagged by antivirus, its presence is less likely to raise suspicion during investigations.
Recommendations for Defenders
Security teams must recognize that DFIR tools like Velociraptor can be weaponized. Defenders are advised to:
- Monitor for unusual deployment of Velociraptor instances, especially on endpoints not run by security teams.
- Audit Velociraptor’s configuration and command logs to catch suspicious behavior early.
- Restrict execution of forensic tools to known and approved systems.
- Ensure that only authorized personnel deploy DFIR software in enterprise environments.
As threat actors increasingly turn to repurposing legitimate tools for nefarious aims, security professionals must remain vigilant — what was built for defense is now a tool for offense.
