Code Injection With C#

Question

I just saw This Question and it made me wonder:

Can you use windows hooks or other methods to do code injection with c#? I've seen lots of things about code injection but all of them are done in C/C++. I don't know either of those languages and have a really hard time translating. Does anyone have any ideas on how to do this?

Answer 1

Kevin, it is possible. You can create library with window hook proc using managed C++. All you need to do is to inject this hook into some application using standard WinAPI (SetWindowsHookEx etc.). Inside this hook you can call System::AppDomain::CurrentDomain->Load method to load your assembly into target application's AppDomain. Then you can call methods defined in your assembly using reflection. For example, Snoop uses this method.

Just came across a link that discusses this subject in detail so I wanted to post it back here: How To Inject a Managed .NET Assembly (DLL) Into Another Process

Answer 3

Mike Stall has this sample, that uses CreateRemoteThread. It has the advantage of not requiring any C++.
