Rules Reference
See references/rules.md for full list of detection rules, severity levels, and whitelisted domains.
Limitations
- Pattern-based detection — cannot catch all obfuscation techniques
- No runtime analysis — only static scanning
- False positives possible for legitimate tools that access network/files
- Always combine with manual review for HIGH/MEDIUM findings
