Gray Hat C# Hacking: Create and Automate Advanced Hacking Tools, Post-Exploitation Scripts, and Payloads

Gray Hat C# Hacking is the definitive guide for cybersecurity professionals, red teamers, and developers who want to master offensive security operations using the power of C#. Whether you're crafting stealthy payloads, automating privilege escalation, or building your own custom post-exploitation tools, this book gives you the practical knowledge and working code to turn your ideas into powerful offensive utilities. Through hands-on, real-world examples, you'll learn how to write in-memory loaders, interact with LSASS to extract credentials, build modular C2 agents, and execute advanced evasion tactics against modern EDRs and AV solutions. You'll develop utilities that persist across reboots, exfiltrate files and clipboard data, inject into remote processes, and leverage LOLBins like msbuild and InstallUtil for stealthy execution. From reflective DLL injection and manual PE mapping to encrypted C2 communications and post-exploitation automation, every concept is backed by concrete C# implementations. This book doesn't just teach techniques-it helps you build an entire offensive toolkit from scratch with modular, extensible, and obfuscated C# code designed for modern red teaming and penetration testing operations. What You'll Learn: Safely interface with LSASS to extract hashes using PInvoke and low-level Win32 APIs Write shellcode runners, reflective DLL injectors, and stealthy launchers in C# Implement advanced persistence techniques using Scheduled Tasks, Services, and Registry keys Capture screenshots, keystrokes, and active windows with real-time exfiltration logic Build a modular, encrypted red team agent with HTTP and Named Pipes transport Perform full kill-chain simulations and refine your toolset based on tactical feedback Use AppDomains, thread injection, and reflection to execute payloads without touching disk Stay within ethical and legal boundaries using best practices and safe lab setups Whether you're a penetration tester, malware developer, or security researcher looking to extend your capabilities using C#, this book equips you with the skills, insights, and source code to build highly effective, stealthy, and customizable hacking tools.
