This expert playbook details advanced attack vectors specific to the HTTP/2 protocol. It covers sophisticated techniques such as h2c smuggling, exploiting pseudo-header discrepancies, HPACK compression vulnerabilities, and abusing stream multiplexing. Use this skill for professional penetration testing and security auditing of H2 services, especially for bypassing proxy-level controls and WAFs.

This expert playbook covers advanced techniques for testing HTTP request smuggling and desynchronization vulnerabilities. It is critical when front proxies, CDNs, or load balancers disagree with the origin server on message framing (Content-Length vs Transfer-Encoding), or during protocol downgrades (HTTP/2 to HTTP/1). Use this to uncover deep security flaws like WAF bypass and session hijacking.

A comprehensive, black-box workflow designed for professional bug bounty hunting and penetration testing. It guides users through a 5-stage methodology (Intake, Recon, Enum, Hunt, Report), covering 19+ advanced attack playbooks (e.g., RCE, SQLi, XSS, SSRF). The skill integrates real-world exploit cases, structured payloads, and WAF bypass techniques for maximizing vulnerability discovery in web applications and APIs.
