Kernel Sockets with C#

Description

This project demonstrates communication with a manually mapped Kernel Driver using WinSock to make a socket server, and a C# User Mode program talking with it using the standard .NET System.Net.Sockets namespace. The aim is to perform various tasks through this interaction.

Whats the point to make the UM in C# compared to C++? This was for a school project to see if it was possible to make it work. I have earlier worked with C++ UM <-> C KM using IOCTL as communication, but wanted to explore other means of communication.

Features

  • Communicate with a kernel driver using sockets with a UM in C#
  • Perform various tasks through kernel-level operations
  • Written in C and C#

Requirements

  • Windows
  • Windows SDK, Windows Driver Kit & Spectre Libraries
  • Visual Studio 2022
  • Some way to manual map the driver, I use kdmapper

Setup

  1. Clone the repository: 
    git clone https://github.com/OssieFromDK/kernel_sockets_csharp.git
  2. Open the solution file with VS22
  3. Build the projects to compile the driver and the C# UM

Usage

  1. Map the driver using something like kdmapper
  2. Open the C# UM App

Big thanks to wbenny for his KSOCKET examples and code, as this was used in this project to make the Socket Server in KM
