Security Auditor

Comprehensive security scanning and audit reporting.

When to Use

• User asks for a security audit or vulnerability scan
• User wants to check code for secret leaks
• User needs dependency vulnerability checking
• Before deploying to production
• When reviewing third-party code or skills

Procedure

1. Secret Scanning

Search for accidentally committed secrets:

# Common patterns to search
grep -rn "API_KEY\|SECRET\|PASSWORD\|TOKEN\|PRIVATE_KEY" --include="*.{py,js,ts,env,yml,yaml,json}" .
grep -rn "sk-[a-zA-Z0-9]\{20,\}" . # OpenAI keys
grep -rn "ghp_[a-zA-Z0-9]\{36\}" . # GitHub PATs
grep -rn "AKIA[0-9A-Z]\{16\}" . # AWS Access Keys

2. Dependency Audit

# Node.js
npm audit --json
# Python
pip-audit
# Docker
docker scout cves image:tag

3. Code Analysis (OWASP Top 10)

Check for:

• A01: Broken Access Control
• A02: Cryptographic Failures
• A03: Injection (SQL, Command, XSS)
• A04: Insecure Design
• A05: Security Misconfiguration
• A06: Vulnerable Components
• A07: Auth Failures
• A08: Software/Data Integrity Failures
• A09: Logging/Monitoring Failures
• A10: SSRF

4. Hermes Skill Security Scan

For reviewing skills before installation:

• Check for data exfiltration patterns (curl to external URLs)
• Look for prompt injection attempts
• Verify no destructive commands without confirmation
• Check environment variable access patterns
• Scan for obfuscated code or encoded payloads

Report Format

# Security Audit Report
**Target:** [project/skill name]
**Date:** [date]
**Risk Level:** Critical/High/Medium/Low

## Findings
| # | Severity | Category | Description | Location |
|---|----------|----------|-------------|----------|
| 1 | Critical | Secrets  | Exposed API key | config.py:42 |

## Recommendations
1. [Prioritized remediation steps]

## Summary
- Critical: X | High: X | Medium: X | Low: X

Pitfalls

• False positives are common — verify each finding
• Don't expose actual secret values in reports
• Some test fixtures intentionally contain fake credentials
• Audit transitive dependencies, not just direct ones
