DLL Injector

A simple Windows DLL injector that uses the classic CreateRemoteThread + LoadLibrary technique. It can inject a DLL into a target process specified by PID or by process name, and also list running processes.

Features

• Inject DLL by PID (-p) or by process name (-n)
• List all running processes with their names and PIDs (-l)
• Clean and modular C++ code (separate files for injection logic, process utilities and CLI parsing)

Requirements

• Windows (or Wine for testing on Linux)
• MinGW‑w64 (for cross‑compilation) or MSVC (Visual Studio)

Usage

injector.exe [options]

Option	Description
-l, --list	List all running processes (PID and name) and exit.
-p, --pid <PID>	Inject into the process with the specified PID.
-n, --name <name>	Inject into the first process with the given name (e.g. notepad.exe).
-d, --dll <path>	Full path to the DLL to be injected.

If no arguments are given, the program shows the help and a process list.

• injector.* – DLL injection logic
• process_utils.* – process enumeration and name lookup
• main.cpp – command‑line interface

Notes

• The injected DLL must match the architecture (32/64‑bit) of the target process.
• Some processes are protected (e.g. system processes, games with anti‑cheat) and will refuse injection.
• Antivirus software may flag this tool as suspicious – that's expected.
