A comprehensive guide to implementing Clean Architecture patterns for both Android and Kotlin Multiplatform (KMP) projects. It covers robust module structuring, dependency inversion rules, defining UseCases and Repositories, and designing the data layer using technologies like Room, SQLDelight, and Ktor. Learn how to separate concerns, maintain platform independence, and manage complex data flows.

This comprehensive guide covers essential security patterns for Perl development, addressing common vulnerabilities like SQL Injection, XSS, Path Traversal, and Shell Injection. It details best practices including using Perl's Taint Mode, implementing strict allow-list validation, performing safe file operations, and executing external commands securely to ensure robust and resilient applications.

A comprehensive utility designed to assess the security posture of modern APIs, including REST, GraphQL, and gRPC. It strictly follows the OWASP API Security Top 10 framework, testing for critical vulnerabilities such as Broken Object/Function Level Authorization (BOLA/BFLA), SQL/NoSQL injection flaws, and weaknesses in authentication mechanisms like JWT manipulation. Essential for security engineers and penetration testers validating complex microservice architectures and API gateways.

A comprehensive guide for conducting penetration testing on iOS and Android mobile applications, adhering to the OWASP MASTG. This skill covers the full mobile attack surface, including static analysis of binaries, dynamic runtime testing, and deep API security assessment. Techniques taught include bypassing certificate pinning, analyzing local data storage (Keychain, SQLite), and identifying vulnerabilities in authentication and network communication.

This tool analyzes Web Application Firewall (WAF) logs (ModSecurity, AWS WAF, Cloudflare) to detect sophisticated SQL injection attack campaigns. It parses diverse log formats, identifies common SQLi payloads (UNION SELECT, OR 1=1), correlates multi-stage attacks, tracks source IPs, and generates detailed incident reports classified by OWASP standards for SOC analysts and security researchers.

A comprehensive framework for penetration testing APIs, designed to detect and exploit critical injection flaws. It covers SQL injection (SQLi), NoSQL injection, OS command injection, LDAP injection, and Server-Side Request Forgery (SSRF). This skill guides the testing of all input vectors—including path parameters, headers, query strings, and request bodies—to assess input validation and backend security posture against industry standards like OWASP.

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 comprehensive guide details the professional process of detecting and exploiting SQL injection vulnerabilities using the powerful sqlmap tool. It covers the entire workflow, from initial vulnerability identification and basic scanning to database enumeration, data dumping, advanced exploitation (like file reading and OS command execution), and WAF bypass techniques, ensuring thorough penetration testing reporting.

This comprehensive guide outlines techniques for authorized penetration testing of real-time web applications using WebSocket connections. It covers discovering various WebSocket endpoints, testing for authentication bypass, identifying Cross-Site WebSocket Hijacking (CSWSH) vulnerabilities, and assessing message handling for injection flaws (SQLi, XSS). Essential for securing chat, trading, and live notification platforms.

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.

Implement robust Static Application Security Testing (SAST) using CodeQL powered by GitHub Advanced Security (GHAS). This solution automates the detection of critical vulnerabilities (e.g., SQL injection, XSS) across large, enterprise-scale codebases, ensuring compliance and maintaining a strong DevSecOps posture throughout the development lifecycle.

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.
