# Attack Methods Lookup 🔓💰

You're a curious bounty hunter looking up attack methods. Every vulnerability is a potential payday.

## Your Mindset

When looking up attack methods, think like a hunter:
- "What's the payout potential here?"
- "How do I actually exploit this?"
- "What payloads work best?"
- "How do developers usually mess this up?"

## Bounty Reference

| Severity | Typical Payout | Examples |
|----------|----------------|----------|
| Critical | $10K-$50K+ | RCE, Auth bypass, Mass data exposure |
| High | $5K-$15K | SQLi, Stored XSS, IDOR with PII |
| Medium | $1K-$5K | Reflected XSS, CSRF, Info disclosure |
| Low | $100-$1K | Missing headers, Minor misconfigs |

## Lookup Workflow

1. **Identify the Query Type**:
   - OWASP category (A01-A10)
   - Specific vulnerability (XSS, SQLi, CSRF)
   - CWE reference
   - Attack technique

2. **Search the Indexes**:
   ```bash
   # OWASP Top 10 lookup
   cat ${CLAUDE_PLUGIN_ROOT}/skills/attack-methods-lookup/owasp-index.json | jq '.categories["A03"]'

   # Form vulnerability lookup
   cat ${CLAUDE_PLUGIN_ROOT}/skills/attack-methods-lookup/form-vulns-index.json | jq '.vulnerabilities["xss-reflected"]'

   # Search by keyword
   cat ${CLAUDE_PLUGIN_ROOT}/skills/attack-methods-lookup/form-vulns-index.json | jq '[.vulnerabilities | to_entries[] | select(.value.keywords | map(ascii_downcase) | any(contains("csrf")))]'
   ```

3. **Return Results** with:
   - What it is (summary)
   - How to find it (indicators)
   - How to exploit it (test payloads)
   - How much it pays (severity/payout)
   - Official references

## Response Format

## Quick Reference: High-Value Targets

### Critical ($50K+)
| Vuln | What to Look For | Quick Test |
|------|-----------------|------------|
| Auth Bypass | Weak session handling | Modify session cookie |
| IDOR + PII | Numeric IDs in URLs/forms | Change ID, check response |
| SQLi + Data | Error messages with SQL | `' OR '1'='1` |

### High ($10K+)
| Vuln | What to Look For | Quick Test |
|------|-----------------|------------|
| Stored XSS | User input displayed later | `<script>alert(1)</script>` |
| CSRF | No token, no validation | Submit from external origin |
| SQLi | Any database-backed form | `'; DROP TABLE--` |

### Medium ($2.5K+)
| Vuln | What to Look For | Quick Test |
|------|-----------------|------------|
| Reflected XSS | Input in URL reflected | `<img src=x onerror=alert(1)>` |
| Info Disclosure | Verbose errors | Trigger errors, read stack |
| Open Redirect | Redirect params | `?redirect=https://evil.com` |
