Windows DLL and Shellcode injection tool for x86/x64 with a graphical interface.

Introduction

S-inject is an open-source Windows DLL and Shellcode injection tool. It supports x86/x64, a graphical interface, and parameter-based usage, with methods including remote thread injection, APC queue injection, reflective injection (manual mapping), and Shellcode injection.

The project is hosted on GitHub under the MIT license. The final exe artifact can be downloaded from GitHub Actions, or built with CMake and Visual Studio 2022. Shellcode uses base64-encoded shellcode.

Notes:

- Reflective injection (manual mapping) references the well-known GitHub project ReflectiveDLLInjection.

- After the 2025-11-28 update, reflective injection supports arbitrary x64 DLL files and enhanced mapping for exception-handling `.pdata`.

- PoolParty injection is currently unstable; the binary Release does not include that update, and some scenarios require SeDebug privileges.

Disclaimer: This tool is for educational and authorized testing purposes only. The developers and contributors do not support, encourage, or endorse any illegal or unauthorized use.
