note; the file is called rootkit.c because.. I couldn't find a better name for it. heh
A LKM (Loadable Kernel Module) to execute a command as root; I include a example of using netcat and a compiled(with source and steps on how to compile) reverse shell provided in C.
Note, this is not really a rootkit-per-say but can be a part of one, more specifically. Obviously, if that's the case - it's for learning purposes. I Never created this to be used illegally.
