Hey, so recently I have been wondering how to detect API hooking to aid prevent cracking, I have been reading up on methods and so far I understand there are two ways of doing it:

1. Check Calls to VirtualProtect
   
2. Hook the IAT address of the process and save bytes into memory, then copy again at a later stage and compare
   

I am new to anti RE but would love to know any other ways/information about this.
