An expert playbook detailing DNS rebinding techniques to bypass the Same-Origin Policy (SOP). This method is used in penetration testing to exploit client-side applications that rely on DNS resolution for origin checks, allowing attackers to trick the browser into sending requests to internal, non-publicly accessible services (like cloud metadata endpoints) while maintaining a seemingly trusted origin.

This skill provides comprehensive testing for WebSocket APIs, covering protocol basics, Cross-Site WebSocket Hijacking (CSWSH), and common security flaws. Use it when testing applications that rely on real-time communication, chat features, or persistent data streams. It validates Origin checks, session binding, and message integrity.
