I made my own CS:GO hack, which I plan to use privately and amongst a couple of friends (max 10).

And of course I want this hack to be vac secure. I heard that if you MD5 Hash your .exe there's really no problem, but it happens that I have a .dll where my hack is coded. I also created my own .dll injector which injects my dll into the game.

So my question is: What steps do I have to take to make my hack undetected and is hashing my injector enough?
