An undetectable cheat?

I'm wondering if this has been done before, or is even possible. If I were to inject a DLL, grab the Lua state, run string through luaL_loadbuffer, using @lua/includes/init.lua as the source, would that be enough if all of that was done before autorun and no traces were left in the global table? What about hook.GetTable and concommand.GetTable. Would I have to fiddle with that as well?

yes hes surely going to hook runstring if he doesn't know c++

wtf
