A collection of standalone C# tools and proof-of-concept programs for offensive security operations, each compiled individually in Visual Studio with no external dependencies. Tools cover persistence, credential phishing, privilege escalation discovery, EDR detection, and post-exploitation techniques on Windows.

Use cases

• find DLL hijacking opportunities on a Windows host
• detect hooked native API functions indicating EDR presence
• phish a user's Windows credentials with a fake prompt
• establish persistence via COM registry keys or SSP DLLs
• encrypt and exfiltrate a directory as an AES-encrypted ZIP
• track a system's GPS coordinates when location services are enabled
• enumerate COM servers and abandoned COM keys for abuse
• inspect .NET assemblies for deserialization and remoting risks

When to choose

• you need small, dependency-free Windows post-exploitation tools you can compile yourself
• you are doing authorized red team or penetration testing on Windows environments
• you want readable C# source to learn how specific offensive techniques work

When to avoid

• you need a maintained, supported security product rather than proof-of-concept code
• your target platform is not Windows
• you cannot compile C# projects or lack authorization to run offensive tooling
