# Pentest Recon Attack Surface

## Purpose
Perform comprehensive attack surface mapping by correlating three data sources: external network scans, authenticated browser exploration, and source code analysis. Produces a structured endpoint inventory with authorization metadata, role/privilege architecture, and prioritized authorization vulnerability candidates for downstream code review and exploitation.

## Prerequisites

### Authorization Requirements
- **Written authorization** with explicit scope for reconnaissance and source code access
- **Source code access** to the target application (white-box engagement)
- **Test accounts** at every privilege level (anonymous, user, admin, service)
- **Network scan approval** — confirm acceptable scan intensity with target owner

### Environment Setup
- nmap, subfinder, httpx, whatweb for external reconnaissance
- Playwright with authenticated browser contexts
- katana or gospider for web crawling
- ffuf for content discovery
- semgrep and ripgrep for source code analysis
- Access to deployment configs (Dockerfile, docker-compose, k8s manifests)

## Core Workflow
1. **Technology Fingerprinting**: Run whatweb + httpx to identify frameworks, languages, server versions, WAF presence, and response header signatures.
2. **External Scan Correlation**: Execute nmap service scan + subfinder subdomain enumeration. Cross-reference discovered services against deployment configs (docker-compose ports, k8s service definitions) to identify exposed vs internal-only services.
3. **Interactive Browser Exploration**: Authenticated Playwright crawl at each privilege level. Capture all XHR/fetch requests, form submissions, WebSocket connections, and dynamic route transitions. Record request/response pairs with auth context.
4. **Route Mapper**: Parse all backend route definitions from source code with file:line pointers. Extract HTTP method, path pattern, middleware chain, and handler function for every endpoint.
5. **Authorization Checker**: For each route, trace the middleware chain to identify auth/authz enforcement. Flag endpoints missing authentication middleware or with inconsistent authorization patterns.
6. **Input Validator**: Analyze validation logic per parameter — identify parameters with no server-side validation, client-only validation, or incomplete validation (e.g., type check but no range check).
7. **Session Handler**: Trace token lifecycle from issuance through validation to expiry. Map session storage mechanism, token rotation policy, and logout invalidation behavior.
8. **Authorization Architecture**: Synthesize role definitions, permission assignments, and privilege lattice from source code. Identify horizontal/vertical/workflow authorization vulnerability candidates.
