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, 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.

A comprehensive guide to advanced SQL injection (SQLi) methodologies for offensive security assessments and bug bounty hunting. Covers all major injection types, including error-based, boolean/time-based blind, out-of-band, and second-order injection. Provides specific payloads and techniques for MySQL, MSSQL, PostgreSQL, Oracle, and NoSQL databases, along with methods for bypassing WAFs, exploiting GraphQL, WebSocket, and modern API filters. Includes full automation workflows using tools like sqlmap.

A comprehensive checklist and methodology for testing Cross-Site Scripting (XSS) vulnerabilities. Covers all major types, including Stored, Reflected, DOM, and Blind XSS, along with advanced techniques like CSP bypass, polyglot payloads, and event handler injection. Essential for web application security testing and bug bounty hunting to identify and mitigate malicious script injection risks.

This comprehensive checklist details how to test for XML External Entity (XXE) injection vulnerabilities. It covers classic, blind, error-based, and out-of-band techniques, enabling testers to identify weaknesses in XML parsers. The methodology includes finding various injection points (e.g., file uploads, SOAP/REST endpoints) and exploiting potential risks like file disclosure, SSRF, and DoS. Use this guide for robust web application security testing and bug bounty hunting.

Squirrel is an advanced, full-cycle AI coding skill designed to guide software development from concept to production. It automatically detects the current project state (greenfield, in-progress, or mature) and adapts an 8-phase engineering pipeline. This comprehensive workflow covers planning, building, rigorous testing, bug hunting, code polishing, documentation, and deployment readiness, ensuring high-quality, maintainable results.

This skill provides advanced threat hunting queries for Microsoft Sentinel/Log Analytics. It detects the behavioral and string fingerprints left by popular offensive Entra ID enumeration tools (like ROADtools, AADInternals, and AzureHound) within both MicrosoftGraphActivityLogs and AADGraphActivityLogs. Use this when investigating suspicious Graph API activity, identifying internal reconnaissance, or building detection rules to surface active intrusions.

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.

A planning framework for authorized security assessments, specifically bug bounty hunting. It guides users to confirm engagement types, define scope, and adopt an attacker mindset before executing tests. Includes workflows for red teaming, pentesting, and internal audits, emphasizing authorization and defensive guidance.

Systematically reproduce, diagnose, and fix bugs using evidence-based debugging techniques, then add regression tests to prevent recurrence.

Perform authorized static analysis on source code to identify security vulnerabilities using tools like Semgrep and CodeQL. This workflow covers pattern hunting, dangerous API detection, and verification of vulnerability fixes. Essential for white-box audits and PR security reviews.

Offensive security skill for hunting API security misconfigurations: mass assignment, JWT none/algorithm confusion, server-side prototype pollution, and server-side parameter pollution in backend URL construction. Requires explicit written authorization and a controlled lab or target scope.
