A comprehensive strategy for regression testing in AI-assisted development. It focuses on identifying systematic blind spots, such as schema inconsistencies between sandbox and production paths, and integrating automated bug checks into the development workflow. This guide teaches how to build robust, database-free API tests to ensure code quality when AI models contribute to the codebase.

This comprehensive guide details advanced techniques for detecting and exploiting NoSQL injection vulnerabilities across various databases like MongoDB and CouchDB. It covers critical attack vectors, including authentication bypass using operators ($ne, $gt), blind data extraction via $regex, and executing arbitrary server-side JavaScript through the $where clause. Essential reading for penetration testers and security researchers assessing NoSQL backends.

This skill guides the process of designing, implementing, and validating advanced security detection use cases for Security Information and Event Management (SIEM) platforms like Splunk, Elastic, and Microsoft Sentinel. It focuses on mapping organizational threat profiles to the MITRE ATT&CK framework to build formal, high-fidelity detection rules, thereby strengthening Security Operations Center (SOC) coverage and reducing blind spots.

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 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.

A comprehensive playbook detailing expert techniques for OS command injection vulnerabilities. It covers all shell metacharacters, blind injection, time-based detection, out-of-band exfiltration methods, and common vulnerable code patterns across PHP, Python, and Node.js. Essential for security analysts and penetration testers.

A sophisticated payload bypass technique targeting Java applications. It exploits the silent loss of high 8 bits when 16-bit Java characters are cast or written as 8-bit bytes. This allows attackers to bypass WAF/IDS security measures by making the WAF see harmless Unicode, while the backend service processes the original malicious ASCII byte payload. Ideal for blind SQLi, deserialization RCE, and path traversal. This primitive affects major frameworks like Tomcat, Spring, Jackson, and HttpClient.

A comprehensive playbook detailing NoSQL injection techniques, moving beyond traditional SQLi. Covers deep vulnerabilities in MongoDB, including operator injection, login bypass, blind data extraction using regex, and $where execution. Also includes attacks specific to Redis, CouchDB, and general API parameter pollution.

A comprehensive, expert-level playbook covering XML External Entity (XXE) vulnerabilities. This guide details advanced attack techniques across multiple contexts, including SOAP, REST, SVG, and Office files. Key topics covered include blind detection, out-of-band (OOB) data exfiltration, local file reading (e.g., /etc/passwd), and chaining XXE to achieve SSRF or RCE.
