Overview

This is a top-level routing skill for bug bounty, web security, API security, and authorized penetration testing.

Its core role is not to replace all specialized techniques, but to help the agent:

  1. First determine the testing phase (Recon / Validation / Privilege Escalation / Chain building)
  2. Then select the correct vulnerability category
  3. Avoid relying only on baseline model memory; prefer structured methodology
  4. Prioritize boundary conditions AI often misses but that matter in real engagements

Trust Model

  • This knowledge base emphasizes content safety and auditability.
  • Use this only within authorized targets, legitimate research, defensive validation, and bug-bounty-approved rules.
  • Do not use these techniques for unauthorized attacks.

When to Use This Skill

Use this skill first in the following scenarios:

  • You just received a new bug bounty target and do not know where to start
  • You need to decide whether to load XSS / SQLi / SSRF / IDOR / JWT / API tracks first
  • You want the agent to perform Web/API security testing with a more stable methodology
  • You need to route scattered findings to the right attack surface
  • You want AI to miss fewer critical test points in security work

Operating Model

Step 1: Start with Recon and context validation

Collect first:

  • Target type: classic web, REST API, mobile backend, admin panel, payment flow, file upload, GraphQL
  • Identity and permission model: anonymous, regular user, admin, multi-tenant
  • Input locations: URL, query parameters, JSON, headers, cookies, filenames, imported files, templates, reflection points
  • Output locations: HTML, attributes, JS, PDF, email, logs, background tasks, mobile endpoints

Step 2: Route by observed behavior

Internal package names / supply-chain inventoryDependency Confusion

Step 3: Use the most likely-hit testing order

  1. Recon / Methodology
  2. API Security / Auth / IDOR
  3. XSS / SQLi / SSRF / SSTI / XXE
  4. Business Logic / Race Condition
  5. Chained exploits and privilege-escalation paths

Core Skill Map

If you have the full repository, prioritize using these topic documents together:

Previously separate mini skills such as payload-selection and brute-selection were merged back into their main skills to avoid router overload and selection noise.

High-Value Expert Intuitions

These are points many baseline models miss, but they are frequently effective in real bug bounty work:

  1. The same filtering logic is often reused across multiple pages: if one point is bypassable, similar pages usually are too.
  2. Parameter names are an attack surface too: WAFs often inspect values but not names.
  3. Second-order vulnerabilities are common: safe at storage time does not mean safe when later read into a dangerous context.
  4. BOLA is fundamentally 'authenticated but unauthorized': replaying with account A/B switching is critical.
  5. Older API versions are most likely to miss patches: fixing v2 does not mean v1 was retired.
  6. Business-logic vulnerabilities often bring highest impact: scanners miss them and they persist longer.
  7. Race conditions should prioritize one-time actions: coupon redemption, claims, resets, invites, trials, inventory deduction.
  8. For JWT attacks, check key and algorithm context first: do not blindly spray payloads; verify alg, kid, JWKS, and key source first.

Suggested Prompts

Use this skill as a router to make the agent clarify phase and goal first:

  • "First, plan the testing route for this target using bug bounty methodology.
  • "This is a REST API; prioritize BOLA, BFLA, Mass Assignment, and JWT angles.
  • "This parameter triggers server-side requests; list key validation points from an SSRF perspective.
  • "This feature is a payment/coupon/inventory flow; prioritize business logic and race-condition analysis.
  • "I only see login and password-reset flows; analyze via Auth Bypass + OAuth/JWT + CSRF.

Guidelines

  • Prioritize routing by target type and observed behavior, not random payload enumeration.
  • When payloads are needed, prefer quick-start / first-pass samples in the corresponding main skill instead of adding another intermediate router.
  • Prioritize reusable filters, shared components, and cross-page reproduction paths.
  • Confirm authentication, authorization, and version boundaries before deeper exploitation.
  • Preserve explainable, auditable, reproducible testing processes.
  • When full repository context is available, return to topic documents for finer exploitation details.
