Cheat-Proof techniques for Online Game(TCP)

I'm creating a game and i'm really worried about hacking, so i'm writting
a anti-cheat inside the game, i searched how the hacks now-a-days are
written and i found some patterns, first of all, almost every hack uses a
thread(Usually with CreateThread()) to create the checking loop(check if
hack is on/off), do any of you have a good way to check if the thread is
not from the game?PS:I also use threads from outside the code(inside DLLs)
