Proceeds to add anti-debugging checks and screws up static analysis :D
Anyways cool idea with the indefinite decoys, managed to write a keygen, fun one.
Really interested how the source code looks
expl0itr on 10:00 AM 04/24/2024: I haven't phrased that well in the description: Patching IS allowed and encouraged to get rid of the anti-debugging techniques and junk bytes. However, patching isn't allowed to force the program to display the flag without you having reversed the key generation algorithm first.
The source code can be found here: https://github.com/juliangrtz/crackmes/tree/main/FortKnox
