## Testing Methodologies

**PTES** (7 phases): Pre-engagement → Intelligence → Threat modeling → Vulnerability analysis → Exploitation → Post-exploitation → Reporting
[Details: `.claude/skills/pentest/attacks/essential-skills/methodology/ptes.md`]

**OWASP WSTG**: 11 categories covering info gathering → client-side security
[Details: `.claude/skills/pentest/attacks/essential-skills/methodology/owasp-wstg.md`]

**MITRE ATT&CK**: Reconnaissance → Initial Access → Execution → Persistence → Privilege Escalation → Defense Evasion → Credential Access → Discovery → Lateral Movement → Collection → C2 → Exfiltration → Impact
[Details: `.claude/skills/pentest/attacks/essential-skills/methodology/mitre-attack.md`]

**Flaw Hypothesis**: Stack analysis → Predict vulnerabilities → Test → Generalize → Correlate findings → Report
[Details: `.claude/skills/pentest/attacks/essential-skills/methodology/flaw-hypothesis.md`]

## OWASP Top 10 (2021)
A01: Broken Access Control | A02: Cryptographic Failures | A03: Injection | A04: Insecure Design | A05: Security Misconfiguration | A06: Vulnerable Components | A07: Authentication Failures | A08: Software/Data Integrity | A09: Logging/Monitoring Failures | A10: SSRF

## Common Tools
- **Playwright**: Browser automation, payload injection, evidence capture [`.claude/skills/pentest/attacks/essential-skills/playwright-automation.md`]
- **Burp Suite**: Proxy, scanner, repeater, intruder, collaborator
- **sqlmap**: `sqlmap -u "URL" -p param --dbs`
- **nuclei**: `nuclei -u target -t cves/`
- **ffuf**: `ffuf -u https://target/FUZZ -w wordlist.txt`
- **nmap**: `nmap -sC -sV -oA output target`

---

## Reporting Requirements

**PoC Verification (CRITICAL)**: Vulnerability requires working PoC script
- `poc.py` - Runnable exploit with args
- `poc_output.txt` - Execution proof + timestamp
- `workflow.md` - Manual steps if applicable
- Evidence: Screenshots, videos, network logs

[Complete spec: `.claude/OUTPUT_STANDARDS.md` lines 258-357]

**Report Format**: Title | CVSS | CWE/OWASP | Reproduction steps | Impact | Remediation

**Output Structure**: `outputs/<target>/findings/{finding-NNN/{poc.py, poc_output.txt, workflow.md}} + reports/{executive-summary.md, technical-report.md}`
