A comprehensive guide for systematically assessing modern API endpoints (REST, GraphQL, gRPC) against the OWASP API Security Top 10 (2023). This workflow covers identifying endpoints, testing for Broken Object Level Authorization (BOLA/IDOR), assessing broken authentication, and validating rate limiting. Use this during authorized penetration tests or before production deployment to ensure robust API security.

This skill provides a comprehensive guide and methodology for identifying and exploiting Cross-Origin Resource Sharing (CORS) misconfigurations in web applications. It covers testing origin validation bypasses, analyzing preflight requests, and simulating data exfiltration during authorized penetration tests, crucial for assessing API security.

This comprehensive guide provides a detailed methodology for performing security testing on web applications that handle email sending (e.g., contact forms, password resets, newsletters). It focuses on identifying CRLF/SMTP header injection vulnerabilities, guiding users on how to check if attackers can manipulate email headers, inject custom content, or abuse forms for spam relay during a penetration test.

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 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.

A guide for security researchers focused on finding exploitable, remote-reachable vulnerabilities for bug bounties or responsible disclosure. It emphasizes high-signal flaws such as SSRF, RCE, and SQL injection, while guiding users through the professional triage and PoC creation process for penetration testing.
