Hey guys, so, I wanted to ask a question, if I edited the code on a already released hack, and add ALOT of trash code and then not share it with anybody but myself, will it stay undetected if I do that everytime CSGO updates?(ADD ALOT MORE TRASH CODE TO CHANGE SIGNITURE AGAIN)

If the answer is Yes, can someone do it for me?(and possibly teach me)
I can give something in return!
