This guide details how to implement robust API schema validation using OpenAPI Specification (OAS) and JSON Schema. It enforces strict input/output contracts, preventing critical vulnerabilities such as injection attacks (SQLi, XSS), data leakage, and mass assignment by validating data types and structure at the API gateway or development level.

Learn how to implement Runtime Application Self-Protection (RASP) agents for Java and Python web applications. This skill covers deploying OpenRASP, detecting OWASP Top 10 attacks (SQLi, XSS, RCE), configuring security policies, and integrating real-time security alerts with SIEM platforms for comprehensive defense in depth.

A powerful operational companion for database developers. This skill assists with the daily lifecycle of database interactions, including translating natural language requirements into optimized SQL queries, generating database migrations, performing comprehensive schema introspection across multiple dialects (PostgreSQL, MySQL, SQLite, SQL Server), and identifying performance bottlenecks through detailed query optimization and index recommendations. It also supports ORM patterns like Prisma and SQLAlchemy.

This comprehensive guide covers best practices for building robust database systems. It teaches crucial concepts like schema normalization, effective indexing strategies, selecting the right database (e.g., SQLite vs PostgreSQL) and ORM, and optimizing queries to prevent common performance issues like N+1 problems. It emphasizes making context-aware architectural decisions.

A comprehensive reference architecture detailing how to automate Apple Notes on macOS. Since there is no public REST API, this system relies on a layered approach using Node.js, JXA scripting via osascript, local SQLite caching, and FSEvents polling. It outlines best practices for creating robust, local automation solutions for note management and data export.

A comprehensive checklist designed for assessing the security posture of GraphQL endpoints. It covers advanced vulnerabilities such as introspection abuse, IDOR, query depth/complexity DoS, injection attacks (SQLi/NoSQLi), and authorization bypass mechanisms. Essential for professional penetration testing and bug bounty hunting.

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 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.

This router serves as the main entry point for comprehensive injection testing. It helps security professionals classify dangerous input flows—such as XSS, SQLi, SSRF, XXE, etc.—by determining the final sink or interpreter (e.g., browser context, database, XML parser, shell). Use it when unsure which specific injection vector to prioritize.

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 and advanced playbook for mastering SQL injection techniques. It covers critical areas including WAF bypass, out-of-band data exfiltration, second-order injection, and exploitation strategies across major database systems (MySQL, MSSQL, Oracle, PostgreSQL). Essential for professional penetration testing and security auditing.
