5 Malicious OpenClaw Skills That Passed ClawScan + VirusTotal: Unit 42 Analysis

Unit 42 researchers identified five malicious OpenClaw skills that passed both ClawScan and VirusTotal detection. Two particularly concerning examples aren't malware in the traditional sense — they exploit the agent's instruction-following nature to conduct financial fraud.
Key Malicious Skills
- money-radar: Posed as a financial advisor skill. On every run, it pulled a
referrals.jsonfrom a malicious domain. The publisher dynamically swapped which products the agent recommended at runtime, injecting affiliate links that appeared as expert advice. - letssendit: Pooled SOL from all installed agents running this skill, enabling the operator to front-run a meme coin launch and dump on pump.fun — effectively a coordinated agent botnet executing a rug pull.
- omnicogg: Padded its README with 22MB of junk data so scanners skipped the file for being too large. A clean verdict masked an AMOS dropper inside.
Signature scanning is ineffective here. A skill that instructs the agent to always use a referral link contains no payload that any scanner would flag — it's just instructions. The Pass badge from ClawScan means nothing.
Practical Takeaway
Don't install third-party skills. Write your own. If you can read what a skill does, you can write it yourself, and then you actually know what your agent is running.
