# Penetration Testing Methodology (PTES-Aligned)

## **Priority: P0 (CRITICAL)**

## Always-Apply Rules

- **No Exploit = No Report**: Every finding requires reproducible Proof-of-Concept. Hypotheses without PoC are discarded.
- **No Production Testing**: All dynamic probes target local/staging only. Confirm authorization before Phase 1.
- **No Single-Platform Bias**: Assess backend, frontend, AND mobile surfaces when in-scope.

## Workflow

Load alongside `/pentest` workflow. Provides methodology backbone for all 7 phases.

1. **Scope** → Define test mode (whitebox/greybox/blackbox), platforms, exclusions.
2. **Recon** → Build asset inventory per platform. See [platform-recon](references/platform-recon.md).
3. **Threat Model** → Rank endpoints by risk. See [threat-modeling](references/threat-modeling.md).
4. **Analyze** → Run vulnerability matrix across all domains. Load `common-owasp`, `common-security-audit`, `common-dast-tooling`.
5. **Exploit** → Validate each finding with PoC. See [exploit-techniques](references/exploit-techniques.md).
6. **Post-Exploit** → Assess blast radius, lateral movement, privilege escalation.
7. **Report** → Audit-grade output with CVSS scoring. See [report-template](references/report-template.md) and [compliance-mapping](references/compliance-mapping.md).

## Platform Coverage Matrix

| Domain | Backend/API | Frontend/Web | Mobile (iOS/Android) |
|---|---|---|---|
| Injection | SQLi, CMDi, NoSQLi, LDAPi | Template injection, DOM sinks | Content provider SQLi, Intent injection |
| XSS | Response encoding | DOM XSS, `innerHTML`, framework bypasses | WebView `loadUrl`, JavaScript bridges |
| Auth | JWT, OAuth, Session, MFA | Token storage, session management | Keychain/Keystore, biometric bypass |
| AuthZ | BOLA/IDOR, BFLA, Mass Assignment | Client-side role gates | Local permission checks without server |
| SSRF | HTTP client + user URL | SSR with user-supplied URL | Custom scheme fetching arbitrary URLs |
| Business Logic | Race conditions, workflow bypass | Client-only validation, price tamper | IAP bypass, receipt validation skip |
| Crypto | Weak hash, missing TLS | HTTP calls, weak CSP | Missing cert pin, cleartext traffic |
| Config | CORS, debug mode, headers | Source maps, debug flags in prod | `debuggable=true`, ATS exceptions |
| Deps/SCA | `npm audit`, `pip-audit`, `cargo audit` | Bundle vuln analysis | `pod audit`, Gradle dependency scan |
| Secrets | Entropy + regex + liveness | Secrets in JS bundles | Keys in BuildConfig/Info.plist |
| LLM/AI | Prompt injection, excessive agency | Output to DOM sinks | Agent tools without confirmation |

## Continuous & Compliance Execution

- **Continuous Testing**: Execute Delta scans on PRs or Replay regression PoCs. See [continuous-pentest](references/continuous-pentest.md).
- **Compliance Mapping**: Map findings to SOC 2, ISO 27001, PCI DSS, or OWASP MASVS. See [compliance-mapping](references/compliance-mapping.md).

## Anti-Patterns

- **No "scan and dump"**: Raw tool output not a pentest. Correlate findings across SAST + DAST + manual.
- **No severity inflation**: Theoretical risk without exploit evidence ≠ confirmed vulnerability.
- **No happy-path-only**: Test error states, edge cases, race conditions, not just golden flow.
