A comprehensive playbook for professional bug bounty hunting and penetration testing. This guide covers systematic reconnaissance, from initial asset discovery (subdomains, IPs) and technology fingerprinting to advanced endpoint and source code mining. Learn the structured methodology used by top hunters to maximize coverage and find high-severity vulnerabilities.

A comprehensive and advanced playbook for mastering SQL injection techniques. It covers critical areas including WAF bypass, out-of-band data exfiltration, second-order injection, and exploitation strategies across major database systems (MySQL, MSSQL, Oracle, PostgreSQL). Essential for professional penetration testing and security auditing.

This playbook provides expert-level techniques for cryptanalysis of symmetric encryption. It details how to exploit weaknesses in various modes and algorithms, including CBC padding oracle attacks, ECB mode exploitation, bit flipping attacks, stream cipher key reuse, and meet-in-the-middle attacks. Essential for authorized penetration testing and CTF challenges.

This playbook provides expert-level techniques for exploiting common infrastructure services that are exposed without proper authentication. Coverage includes Redis RCE, Rsync data theft, PHP-FPM code execution, AJP file reads, and MongoDB/Hadoop vulnerabilities. Essential for deep penetration testing and security auditing.

An expert-level playbook covering non-obvious XSS techniques, advanced payload selection across various sinks (DOM, SVG, HTML attributes, JavaScript), and sophisticated defense bypass strategies. Use this guide for real-world penetration testing, including WAF bypass, CSP bypass, HttpOnly bypass, and XS-Leaks side channel exploitation. It assumes deep knowledge of web vulnerability mechanics.
