# Pentest Business Logic

## Purpose
Identify flaws in application workflow enforcement, business rule validation, and state machine integrity that cannot be found by taint analysis or pattern matching. These vulnerabilities require understanding intended behavior and finding deviations.

## Prerequisites

### Authorization Requirements
- **Written authorization** with explicit scope for business logic testing
- **Test accounts** at multiple privilege levels (user, admin, premium, etc.)
- **Test payment methods** or sandbox payment environment for financial testing
- **Rollback plan** for any data-mutating tests (order creation, account changes)

### Environment Setup
