A comprehensive guide for advanced penetration testing designed to identify flaws in application business rules that automated scanners miss. Focus areas include price manipulation, workflow bypass, privilege escalation, and race conditions. Essential for securing e-commerce platforms, financial systems, and multi-step critical processes.

This skill guides comprehensive security testing for Host Header Injection vulnerabilities in web applications. It simulates attacks to identify critical risks such as password reset poisoning, web cache poisoning, Server-Side Request Forgery (SSRF), and virtual host routing manipulation. It is essential for penetration testers assessing backend security behind proxies and load balancers.

This guide details a comprehensive methodology for testing JSON Web Token (JWT) implementations against critical security vulnerabilities. It covers attacks such as algorithm confusion (e.g., RS256 to HS256), 'None' algorithm bypass, Key ID (kid) injection, JKU/X5U manipulation, and brute-forcing weak secrets. Essential for API and SSO security assessments.

This skill provides a comprehensive methodology for identifying and exploiting open redirect vulnerabilities in web applications. It covers advanced bypass techniques (e.g., URL encoding, protocol-relative URLs, path traversal) and demonstrates chaining with other flaws like OAuth redirection for advanced phishing simulations and token theft. Designed for authorized security professionals conducting penetration tests.

A comprehensive guide for performing security assessments to identify various forms of sensitive data exposure, such as leaked API keys, PII in API responses, insecure client-side storage, and unprotected data transmission. This workflow covers scanning JavaScript files, analyzing API responses, verifying data encryption, and examining browser storage.

A comprehensive guide and set of payloads for penetration testing web applications that process XML input. It details how to test for major vulnerabilities such as XXE, XPath injection, SSRF, and XML parsing attacks, providing step-by-step workflows and advanced payloads for identifying data exposure and security flaws.

This comprehensive skill guides the testing of web applications for Cross-Site Scripting (XSS) vulnerabilities. It covers reflected, stored, and DOM-based injection points. Testers learn to map input/output contexts, craft context-appropriate payloads, and bypass complex sanitization and CSP protections, ensuring thorough client-side security assessment.

A comprehensive guide detailing how to identify and validate Cross-Site Scripting (XSS) vulnerabilities using Burp Suite's advanced tools (Repeater, Intruder, DOM Invader). This methodology covers reflected, stored, and DOM-based XSS, and includes strategies for bypassing security filters and Content Security Policy (CSP), making it essential for web application penetration testing and bug bounty programs.

A comprehensive guide for assessing the security of JSON Web Token (JWT) implementations. This toolkit details attacks against cryptographic weaknesses, including algorithm confusion (e.g., RS256 to HS256), 'none' attacks, brute-forcing HMAC secrets, and claim manipulation. Ideal for penetration testing and security audits of modern APIs and SSO systems.

A comprehensive guide and toolkit for performing deep security assessments on mobile application backends. It covers identifying vulnerabilities such as broken authentication, insecure token management (JWT, opaque tokens), session fixation, privilege escalation, and IDOR (Broken Object-Level Authorization) across various OAuth flows (OIDC, PKCE). Essential for penetration testers assessing API security.

This comprehensive tool assesses critical security flaws in OAuth 2.0 and OpenID Connect (OIDC) implementations. It systematically tests for common vulnerabilities like authorization code interception, redirect URI manipulation, CSRF in OAuth flows, token leakage, and scope escalation. Ideal for penetration testers and security engineers evaluating the robustness of identity providers and client applications.

A comprehensive guide and framework for assessing real-time WebSocket APIs (ws:// or wss://). This skill covers critical security checks, including Cross-Site WebSocket Hijacking (CSWSH), authentication bypass, message injection attacks, input validation flaws, and denial-of-service (DoS) via message flooding. It utilizes tools like Burp Suite and Python for simulating malicious payloads and ensuring secure real-time communication channels.
