DLL Inj3cti0n

Another dll injection tool.

Overview

This tool is a implementation of differentes injection / execution of DLL.
Works on :

Method	Windows XP	Windows Seven 32bits	Windows Seven 64bits
CreateRemoteThread	+	+	-
Injection shellcode	+	+	-
QueueUserAPC()	+	+	-

NOTES :

• On Windows XP by default I enable debug token in order to inject in system process.
• Its works on Windows Seven 64bits but only on 32bits application.
• On Windows Seven the application need to be on the same session that the user who has launched the tool.
• The method using QueueUserAPC() has been tested on notepad application (once the injection done, click on open).

The DLL that I used to inject different process is also present.
I developed this tool in order to learn dll injection.
Don't hesitate to help me to improve it.
The tool has been compiled with Visual Studio Express 2013.

Usage

C:\> inject.exe <DLL> <PID>

DLL : Path of the DLL
PID : PID of the targeted process

Example : 

C:\tmp> inject.exe dll.dll 42

To do

1. CreateRemoteThread method
2. Without CreateRemoteThread() method (injection shellcode)
3. QueueUserAPC() method
4. NtCreateThreadEx() method
5. SetWindowsHookEx() method
