Race Condition / TOCTOU Attack

Objective

Exploit time-of-check-to-time-of-use (TOCTOU) vulnerabilities by sending concurrent requests that bypass server-side validation.

Testing Methodology

Phase 1: Identify Targets

State-changing operations vulnerable to race conditions:

  • Coupon/promo code redemption
  • Fund transfers / payments
  • Vote/like systems
  • Account creation (duplicate)
  • Inventory purchase
  • Password/email change
  • File operations

Phase 2: Automated Race Testing

This is the opening of the README. Read the full README on GitHub.
