Skill UI

A comprehensive guide and technique set for detecting and exploiting race condition vulnerabilities in web applications. It focuses on bypassing rate limits, exploiting Time-of-Check-to-Time-of-Use (TOCTOU) flaws, and duplicating transactions using advanced methods like Turbo Intruder's single-packet attack. Ideal for security assessments of state-changing operations (e.g., payments, inventory management, coupon redemption).

A comprehensive guide for performing authorized security assessments on GraphQL APIs. This skill covers key areas such as endpoint discovery, schema introspection, testing for authorization flaws (BOLA/BFLA), injection vulnerabilities (SQL/NoSQL), and denial-of-service risks. Essential for penetration testers and bug bounty researchers targeting modern web applications.

A comprehensive tool designed for assessing the security posture of Programmable Logic Controller (PLC) firmware. It specializes in detecting critical vulnerabilities such as hardcoded credentials, undocumented debug interfaces, backdoor functions, and memory corruption flaws. The tool supports analyzing major industrial platforms (Siemens, Allen-Bradley) by performing static and dynamic analysis, and verifying firmware integrity against known-good baselines, adhering to standards like IEC 62443. Use only in authorized lab environments.

A comprehensive guide for performing systematic security assessments on web applications. Following the OWASP Web Security Testing Guide (WSTG), this process identifies critical vulnerabilities such as broken authentication, authorization flaws (IDOR), SQL injection, and Cross-Site Scripting (XSS). The workflow covers reconnaissance, mapping, and advanced testing techniques using tools like Burp Suite and sqlmap, ensuring deep coverage beyond automated scanner capabilities. Ideal for pre-production security validation and compliance audits.

A comprehensive security script designed to test REST API authentication mechanisms for common vulnerabilities. It assesses broken token validation, missing authentication on critical endpoints, weak password policies, and session management flaws. The tool specifically evaluates JWT implementation, API key handling, and adherence to OWASP API Security Top 10, helping identify authentication bypasses before production deployment.

A comprehensive methodology for penetration testing web applications to identify broken access control vulnerabilities. This guide covers systematic testing for Role-Based Access Control (RBAC), privilege escalation, insecure direct object references (IDOR), and API authorization flaws in multi-tenant environments. It outlines the use of tools like Burp Suite and ffuf to map endpoints and simulate various user roles.

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.

This comprehensive checklist guides thorough security testing of OAuth 2.0 and OpenID Connect (OIDC) protocols. It covers advanced vulnerabilities such as authorization code interception, PKCE bypass, CSRF flaws, and improper scope validation. The methodology emphasizes modern industry standards like FAPI (DPoP, JAR, PAR), making it essential for penetration testers and security researchers assessing web application integrity and API security.

A comprehensive methodology and checklist for identifying and exploiting race conditions (TOCTOU) in web applications. It guides users to find timing windows, detect vulnerabilities like double-spend or rate limit bypass, and exploit concurrent request flaws in state-changing business logic. Essential for penetration testing and bug bounty hunting.

A comprehensive guide detailing attack methodologies for Z-Wave smart home networks. Techniques covered include sniffing during inclusion (S0/S2), exploiting key derivation flaws, performing replay attacks on unauthenticated nodes, and crucial hub compromise (pivoting) to gain full control over the entire mesh network. Essential reading for IoT penetration testing.

A comprehensive playbook for advanced security testing, focusing on race conditions and TOCTOU (Time-of-check to time-of-use) vulnerabilities in web applications. It guides users to exploit non-atomic, state-changing operations (e.g., coupons, balance deductions, single-use rewards) by sending highly synchronized, parallel requests (including HTTP/2 single-packet attacks). Essential for identifying weaknesses in authorization and transactional integrity.

This expert playbook covers advanced techniques for testing HTTP request smuggling and desynchronization vulnerabilities. It is critical when front proxies, CDNs, or load balancers disagree with the origin server on message framing (Content-Length vs Transfer-Encoding), or during protocol downgrades (HTTP/2 to HTTP/1). Use this to uncover deep security flaws like WAF bypass and session hijacking.
