Skill UI

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 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.

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.

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.

This tool implements the Stakeholder-Specific Vulnerability Categorization (SSVC) framework, providing a structured decision-tree methodology for advanced vulnerability prioritization. It moves beyond traditional CVSS scoring by incorporating critical factors such as active exploitation status (CISA KEV), technical impact, automatability, and mission prevalence. It generates actionable remediation priorities (Track, Attend, Act) to guide security teams in managing risk and improving security program maturity.

tRPC allows developers to build highly type-safe APIs in a full-stack environment without needing to write or maintain separate schemas. It provides end-to-end type safety from server routers to client components, supporting queries, mutations, subscriptions, and robust middleware. Ideal for building modern TypeScript monorepos, Next.js, or Remix applications.
