This program seems to be packed. Our team was unable to unpack it. Please, you are our last hope! It doesn't matter how, just unpack the program and crack it. Good luck.

jeffli6789 on 6:46 AM 07/07/2020: I used gcore to dump the program before I input anything. To increase the difficulty, try to do anti-debugging BEFORE asking for any input (but also after unpacking itself). Also, as pointed out by @s4r, there is a small glitch of the program so that a partial password also passes the validation.
