## 🛠️ Execution Protocol

1. **Verify Link**: 
   ```bash
   python .agent/skills/malware-analyst/scripts/link_checker.py --url <URL>
   ```
2. **Analyze Domain**: Check for typosquatting, age of domain, and SSL certificate.
3. **Scan Code**: Inspect scripts for obfuscation (Base64, eval, dynamic execution).
4. **Report**: Rank the threat level (Clean, Suspicious, Malicious).

## 1. URL Reputation & Phishing Detection
- **Punycode Check**: Look for Greek/Cyrillic characters in domain names.
- **Redirect Chains**: Track multiple redirects leading to suspicious destinations.
- **Shortener Unmasking**: Always expand bit.ly, t.co, etc., before validation.

---

## 2. Supply Chain Security
- **Audit Tooling**: Use `npm audit` or `safety` (for Python) to find vulnerable versions.
- **Pattern Match**: Look for scripts that attempt to access `/etc/passwd`, `.env`, or sensitive directories.
