Gray Hat C# in Action: Learn to Code Security Tools, Automate Recon, and Advance Your Pentesting Skills

Gray Hat C# in Action: Learn to Code Security Tools, Automate Recon, and Advance Your Pentesting SkillsMaster the art of penetration testing and security automation with the power of C#. This book takes you step by step through building your own custom tools, automating reconnaissance, and applying advanced techniques to real-world pentesting scenarios-all in a safe and controlled way.Unlike generic introductions to security, Gray Hat C# in Action is practical, hands-on, and written with developers in mind. You won't just learn the theory-you'll write the code, run the tools, and see exactly how attackers and defenders think in modern environments.Inside this book, you will learn how to: Build reconnaissance tools that automate DNS lookups, HTTP header parsing, and web crawling.Develop custom port scanners, banner grabbers, and fingerprinting tools using C#.Implement parallelism and asynchronous programming to dramatically speed up scans.Write web application recon utilities, including subdomain brute forcers and API integrations with Shodan and Censys.Interact directly with Windows systems through the Registry and native APIs.Create safe lab-based examples of keylogging, privilege escalation checks, and reverse shells.Explore red teaming techniques such as droppers, obfuscation, Active Directory enumeration, and persistence automation.Understand how defenders detect C#-based tools and how to apply those lessons to improve both offense and defense.Design a modular pentesting framework with plugin support for extending your toolkit.Package, document, and distribute your tools like a professional.Whether you're a penetration tester looking to extend your toolkit, a developer who wants to understand how attackers think, or a learner eager to sharpen your security skills, this book gives you the technical knowledge and practical exercises to level up.Why C#? C# offers a unique advantage in pentesting. It is tightly integrated into the Windows ecosystem, widely supported in enterprise environments, and powerful for building cross-platform tools. With .NET, you gain access to a robust standard library, strong performance, and modern programming features that make writing security tools efficient and maintainable.Powerful Call to Action The best way to learn security is by building, experimenting, and applying what you know. Gray Hat C# in Action is your guide to doing exactly that. Don't just read about pentesting tools-create them, run them, and understand them from the inside out.Take control of your learning, sharpen your skills, and start building tools that make you a stronger pentester and a smarter defender.Get your copy today and start coding your way into professional-grade security expertise.
