Skill Auditor

Skill Auditor 🔍

Audit ClawHub skills for security threats before installing them.

Triggers

Use this skill when:

• "Audit this skill"
• "Check skill security"
• Before installing any third-party skill

Usage

Method 1: Pre-install audit (recommended)

# Inspect without installing
clawhub inspect <skill-name>

# Run the audit script
~/.openclaw/workspace/skills/skill-auditor/scripts/audit.sh <skill-name>

Method 2: Audit an installed skill

~/.openclaw/workspace/skills/skill-auditor/scripts/audit.sh --local <skill-path>

Detection Layers

L1: Pattern Matching

L2: Deobfuscation

Automatically decodes hidden malicious payloads:

• Base64 — Decodes and scans for hidden commands
• Hex — Decodes \x41\x42 format strings
• Checks decoded content for C2 servers and dangerous commands

L3: LLM Analysis (optional)

Uses Gemini CLI to analyze suspicious code intent:

• Semantic understanding beyond pattern matching
• Detects novel/unknown threats
• Requires gemini CLI installed

Known Indicators of Compromise (IoC)

C2 Server IPs

91.92.242.30  # ClawHavoc primary server

Malicious Domains

glot.io       # Hosts obfuscated scripts
webhook.site  # Data exfiltration endpoint

Social Engineering Keywords

OpenClawDriver    # Non-existent "driver"
ClawdBot Driver   # Social engineering lure
Required Driver   # Tricks users into installing malware

Best Practices

1. Always audit before install — Never skip the security check
2. Trust no skill blindly — Including highly starred or popular ones
3. Check updates — Skill updates may introduce malicious code
4. Report suspicious skills — Send to steipete@gmail.com

Maintenance

Update this skill when new threats are discovered:

1. New malicious IP → Add to MALICIOUS_IPS
2. New malicious domain → Add to MALICIOUS_DOMAINS
3. New social engineering lure → Add to SOCIAL_ENGINEERING
4. New attack pattern → Add regex detection
