Unless the developer accidentally delivers a slim .exe without malware and and a fat one with said malware.
In this case, there is no need to crack so why would they?
I'm no fan of Denuvo, but cut them some slack!
Simply swapping the names of two executables - the clean version only being there accidentally - is no real "crack".
Although i understand why your source presents it as such and admittedly giggled behind my desk while reading it.
