Security Scanner for OpenClaw/Clawdbot Skills
Protect yourself from malicious skill installations. ClawGuard scans skills for dangerous patterns before you install them - including patterns from the ClawHavoc campaign (341 malicious skills discovered by Koi Security).
Quick Start
# Scan a skill by name
python scan.py --skill <skill-name>
# Scan a skill by path
python scan.py --path /path/to/skill
# Scan all installed skills
python scan.py --all
What It Detects
| Category | Examples | Severity |
|---|---|---|
| 🔴 Reverse Shells | socket.connect(), pty.spawn(), /dev/tcp | Critical |
| 🔴 Data Exfiltration | requests.post() to suspicious TLDs | Critical |
| 🔴 Credential Harvest | Reading ~/.ssh/id_rsa, AWS credentials | Critical |
| 🔴 Obfuscation | base64.b64decode(exec), chr() chains | Critical |
| 🔴 ClawHavoc IOCs | glot.io scripts, fake Apple URLs, known C2 IPs | Critical |
| 🟠 Code Execution | exec(), eval(), subprocess | High |
| 🟡 Suspicious Network | URL shorteners, weird ports | Medium |
Output Formats
# Console (default) - colored terminal output
