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.

A comprehensive skill guide for assessing JSON Web Token (JWT) security flaws. This technique covers advanced attack vectors such as algorithm confusion (e.g., RS256 to HS256), 'none' algorithm bypass, key ID (kid) injection, and JKU/X5U parameter manipulation. It also includes methods for brute-forcing weak symmetric secrets and is essential for penetration testing OAuth2/OIDC and SSO systems.

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.

A detailed methodology for identifying Cross-Site Scripting (XSS) vulnerabilities across web applications. It guides systematic testing for Reflected, Stored, and DOM-based XSS, covering payload bypass, output encoding evaluation, and assessing Content Security Policy (CSP) protection. Essential for OWASP WSTG testing and client-side security audits.

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.

This guide details methodologies for identifying and exploiting XML External Entity (XXE) injection vulnerabilities in web applications. It covers basic file retrieval, blind XXE detection using out-of-band techniques, and data exfiltration, all critical steps during authorized penetration testing of XML-consuming APIs and services.

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.

A comprehensive security tool designed to assess the resilience of OAuth 2.0 and OpenID Connect (OIDC) implementations. It probes for critical misconfigurations and security flaws, including authorization code interception, redirect URI manipulation (open redirects), CSRF vulnerabilities, scope escalation, token leakage, and PKCE bypass. Essential for penetration testing of Single Sign-On (SSO) systems and API security.

A comprehensive guide and code suite for performing penetration testing on real-time WebSocket APIs (WS/WSS). This tool assesses vulnerabilities including Cross-Site WebSocket Hijacking (CSWSH), missing handshake authentication, message injection, input validation failures, and DoS risks. It guides users through analyzing the handshake process and testing authorization enforcement using Python and specialized tools.

This comprehensive guide implements External Attack Surface Management (EASM). It integrates leading industry tools like Shodan, Censys, subfinder, httpx, and nuclei for deep reconnaissance. Users can systematically discover assets, enumerate subdomains, fingerprint services, scan for vulnerabilities, and calculate weighted exposure scores based on professional OWASP methodology. Ideal for continuous security monitoring and deep penetration testing.

This comprehensive skill provides a systematic framework for performing deep security assessments on iOS applications. It covers static analysis of IPA packages, dynamic instrumentation using Frida and Objection, SSL pinning bypass for traffic interception, extraction and auditing of sensitive data from the Keychain, and runtime method hooking. Use this for authorized penetration testing against standards like OWASP MASTG.
