Windows DLL Injector - Level 1

This project demonstrates a simple DLL injection tool built in C++ using the Windows API. It injects a DLL into a running process by taking the target's PID and using functions like OpenProcess, VirtualAllocEx, WriteProcessMemory, and CreateRemoteThread.

🧰 Features

• Basic DLL injection into target processes
• Uses Windows API functions for memory allocation and thread creation
• Successfully injects a sample MessageBox.dll into a custom executable

🧪 Usage

1. Run your target executable and get its PID.
2. Run the injector: ./Local_Dll_injector.exe
3. Enter the PID when prompted.
4. If successful, the DLL will be injected and its code executed.

✅ Tested on Windows 10/11. Some system apps like Notepad might have protection — use a custom test app instead.

🛠️ Future Plans

• Add advanced injection techniques (manual mapping, reflective injection, shellcode injection)
• Support for DLL Hijacking examples
• Create an interactive GUI version of the injector
• Detection bypass techniques for AV/EDR evasion
