| version | 2.0.0 |
| description | Security scanner for OpenClaw skills. Detects malicious code, obfuscated payloads, prompt injection, social engineering, typosquatting, and data exfiltration before installation. Features 0-100 numeric risk scoring, MITRE ATT&CK mappings, base64/hex deobfuscation, IoC database, whitelist system, and SHA256 file inventory. Use before installing any third-party skill. Triggers: audit skill, check security, scan skill, is this skill safe, security review, quarantine.

Skill Auditor v2.0 🔍🛡️
Comprehensive security scanner for OpenClaw/ClawHub skills. Merges static analysis, deobfuscation, and threat intelligence into a single Python tool.
When to Use
- Before installing any third-party skill from ClawHub
- When reviewing skill updates for security regressions
- To audit your own skills before publishing
- When someone asks: "is this skill safe?", "audit this", "check security"
Quick Start
Audit a local skill directory
python3 {baseDir}/scripts/audit_skill.py /path/to/skill --human
Audit a ClawHub skill by slug
python3 {baseDir}/scripts/audit_skill.py --slug skill-name --human
Quarantine workflow (audit + prompt to install)
bash {baseDir}/scripts/quarantine.sh /path/to/skill
bash {baseDir}/scripts/quarantine.sh --slug skill-name
JSON output for programmatic use
python3 {baseDir}/scripts/audit_skill.py /path/to/skill --json
Scoring System
| Score | Level | Action |
|---|
| 0–20 | ✅ SAFE | Auto-install OK |
| 21–40 | 🟢 LOW RISK | Proceed with caution |
| 41–60 | 🟡 MEDIUM RISK | Manual review required |
| 61–80 | 🟠 HIGH RISK | Expert review needed |
| 81–100 | 🔴 CRITICAL | Do NOT install |
Exit codes: 0 = safe (≤20), 1 = review (21–60), 2 = dangerous (>60)
Detection Layers
Layer 1: Static Pattern Analysis
- 10+ scan categories with regex patterns
- Shell execution, network calls, env access, filesystem escape
- Prompt injection, data exfiltration, crypto wallet access
- Dynamic imports, browser credential theft, fake prerequisites
Layer 2: Deobfuscation
- Base64 string extraction and decode → re-scan decoded content
- Hex escape sequence decode → re-scan
- Detects hidden commands, C2 IPs in encoded payloads
Layer 3: Threat Intelligence
- IoC database: known malicious IPs, domains
- Social engineering detection: urgency, false authority, fear tactics
- MITRE ATT&CK ID mapping on every finding
- Whitelist system reduces score for safe binaries/domains
Additional Checks
- SHA256 file inventory for integrity verification
- Typosquat detection (Levenshtein distance on package names)
- Zero-width character detection in SKILL.md
- Comment-context severity reduction (findings in comments scored lower)
- Permission scope analysis (what tools does the skill request?)
IoC Database
Structured threat data in references/ioc-database.json. Update when new threats emerge. The scanner auto-loads this file at runtime.
