## What it is
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

## Facets
- artifact type: library
- maturity: maintenance
- function: security, penetration-testing, developer-tools
- domain: security, penetration-testing, windows, developer-tools
- platform: windows, dotnet, cpp
- tags: red-team, offensive-security, csharp, persistence, privilege-escalation, edr-evasion, proof-of-concept
