A comprehensive checklist detailing advanced attack methodologies for JSON Web Tokens (JWT). Covers critical misconfigurations such as algorithm confusion (alg:none, RS256→HS256), weak secret brute forcing, header injection (kid, jku, jwk), cache poisoning, and improper validation. Also provides specific vectors for extracting JWTs from mobile environments (Android/iOS). Ideal for penetration testers conducting deep security assessments on authentication systems.

A comprehensive reference and bypass catalog covering modern operating system kernel mitigations such as KASLR, SMAP, SMEP, KPTI, DEP/NX, and CFI. It details how these security mechanisms function, how to detect their presence, and advanced bypass techniques (e.g., side-channel attacks, ROP chains, information leaks). This skill is essential for security professionals conducting deep penetration testing, exploit development, and target hardening assessments.

This comprehensive checklist guides users through identifying and exploiting open redirect vulnerabilities in web applications. It covers parameter identification, advanced bypass techniques (e.g., URL encoding, CRLF injection), and chaining the vulnerability with other flaws like OAuth or SSRF. Ideal for web application penetration testing and bug bounty hunting.

This skill provides a comprehensive operational checklist for identifying and exploiting HTTP Parameter Pollution (HPP) vulnerabilities. It details how various web technologies (ASP.NET, PHP, Python, etc.) handle duplicate parameters differently (e.g., first-wins, last-wins, concatenation). Use this skill during penetration testing to discover flaws in parameter parsing, which can lead to bypassing WAFs, performing logic manipulation, or achieving unauthorized access.

This skill provides a comprehensive, structured methodology and checklist for identifying Remote Code Execution (RCE) vulnerabilities across various web applications. It covers advanced attack vectors such as OS command injection, Server-Side Template Injection (SSTI), insecure deserialization, file upload flaws, and XXE. Use this guide during web application penetration testing or bug bounty hunting to systematically discover arbitrary code execution paths.

Guides assessment of KRACK and FragAttacks against WPA2 clients, including official test scripts, likely vulnerable embedded and legacy devices, practical impact, detection, and reporting for modern penetration testing.

A comprehensive playbook for bypassing 401/403 Forbidden errors. Covers advanced techniques like path normalization tricks (encoding, traversal), HTTP method tampering, IP spoofing headers, and protocol downgrade attacks. Essential knowledge for penetration testing and security auditing.

A comprehensive playbook for expert-level Android application security testing. It covers advanced exploitation techniques, including SSL pinning bypass (using Frida/Objection), detecting component exposure (activities, providers, services), and exploiting WebView vulnerabilities (RCE, XSS). Essential for authorized mobile penetration testing assessments.

A comprehensive playbook for security testing APIs relying on JWT, bearer tokens, or API keys. It covers token validation weaknesses (e.g., 'alg:none', RS256 confusion), claim misuse, header spoofing, rate limit bypass, and mass assignment vulnerabilities. Ideal for penetration testers assessing authentication boundaries.

A comprehensive playbook for identifying authentication vulnerabilities in web applications. Covers advanced topics including SQL injection login bypass, predictable password reset tokens, account enumeration techniques, multi-factor authentication bypass, and brute-force resistance checks. Essential for penetration testers assessing login mechanisms and session management.

This comprehensive guide details advanced techniques for circumventing Content Security Policies (CSP). It covers exploiting weaknesses in critical directives (e.g., base-uri, object-src), abusing nonces, leveraging trusted CDN endpoints, and executing code despite strict controls like script-src 'self' or 'strict-dynamic'. Essential knowledge for deep security auditing and penetration testing.

This expert playbook provides comprehensive techniques for testing Cross-Site Request Forgery (CSRF) vulnerabilities in web applications. It covers identifying state-changing endpoints, bypassing anti-CSRF tokens (including missing validation and predictable tokens), and exploiting modern weaknesses like SameSite=Lax via GET methods or misconfigured JSON APIs. Essential reading for security professionals and penetration testers.
