RE: [GD-Windows] Hijacking application

[Gareth L. <GL...@cl...>]

The first thing you want to do is inject a DLL into the address space of the
tool. Another way is to write a dummy dll wrapper for a dll it uses (D3d.dll
is often used) and then you can just agregate the original DLL and add your
own stuff.

A lot depends on what you want to actually do.

Probably the best example of a forced in plugin that I know of DECAL. It's
basically a framework for plugins into Asheron's Call's client. Take a look
at http://sourceforge.net/projects/decalac/

So share with us your goal, and we'll try help you hax0r them :)
