Security Audit of Captured Traffic
Perform a comprehensive security audit of the mitmproxy dump (log.txt) for: $ARGUMENTS
Requires:log.txtin the current directory. If it's missing, capture traffic first: ``bash mitmdump --set flow_detail=3 2>&1 | tee log.txt``
Audit Checklist
Run these checks systematically:
1. Reconnaissance
- List all unique domains/subdomains seen
- List all API endpoints with methods
- Identify API patterns (REST, GraphQL, etc.)
2. Authentication & Session
- Check for missing authentication on sensitive endpoints
- Look for session tokens in URLs or GET params
- Check cookie security flags (Secure, HttpOnly, SameSite)
- Identify predictable session/token patterns
3. Authorization (IDOR)
- Find sequential/enumerable IDs in URLs
- Check for base64 encoded IDs (easy to decode/iterate)
- Look for user IDs, order IDs, transaction IDs
- Test if one user's token works for another's resources
4. Data Exposure
- PII in responses (email, phone, address)
- Partial/full credit card numbers
- Passwords or hashes in responses
- Internal IPs, file paths, stack traces
5. Secrets & Keys
- API keys in requests/responses
- Hardcoded tokens or salts
- Cloud credentials (AWS, GCP, Azure)
- Third-party service keys
6. Payment Security
- Checksum/hash validation on callbacks
- Amount manipulation possibilities
- Status parameter tampering
- Signature collision vulnerabilities
7. Input Validation
- OTP in response (should only be sent via SMS/email)
- Rate limiting on sensitive endpoints
- Enumerable endpoints without protection
8. Transport Security
- HTTP instead of HTTPS for sensitive data
- Missing security headers
- Referer leakage to third parties
Output Format
For each finding, provide:
- Endpoint: The vulnerable URL/API
- Vulnerability: Type of issue
- Evidence: What was found in the traffic
- Severity: Critical/High/Medium/Low/Info
- Recommendation: How to fix
Prioritize findings by severity and exploitability.
