cupycake on 6:52 PM 06/06/2021: what's the password for the zip?
Saptam on 11:29 AM 06/07/2021: Password is crackmes.one
Saptam on 11:32 AM 06/07/2021: Thank you @nanashi
azukame on 4:01 PM 06/07/2021: Very simple crackme which is perfect for beginners.
Luxiferr on 10:10 PM 06/11/2021: Very good for beginners, simple and easy to do Tip:
Breakpoint on test eax,eax and look at ECX :)
GeneralBison on 3:37 PM 06/15/2021: I've figured out the solution, but I can't quite figure out *why* based on my decompiler. I'm still getting used to static analysis, I'm trying to get to the point where I don't just ignore elements of the decompilation because I don't understand it.
GeneralBison on 3:39 PM 06/15/2021: Okay, looking at azukame's IDA decompilation, it makes much more sense than mine through Ghidra, not sure what's produced my erroneous results.
bob123 on 5:22 PM 06/29/2021: Nice, i was first wondering why it did not make sense what i got via looking statically, i guess i forgot about endianness :D

StefanCicos on 7:19 AM 11/25/2021: I tried solving the crackme but I just couldn't look away from all those win api calls :p
Jokes aside this is MALWARE. Please don't run it
Powoli on 7:14 PM 03/09/2022: Virus.
PinkDraconian on 8:41 PM 03/17/2022: This challenge contains malware. Do not run this!
PinkDraconian on 11:31 PM 03/17/2022: After looking into this for a bit longer, and discussing with some others, this most likely is not a virus.
All changes being made to the registry seem to be to measure performance and not of malicious intent.
Don't take my entire word for it, but I think it's a fun exercise to try and reverse it!
qdeer on 11:13 AM 03/25/2022: Nice first program!
trungkientran on 8:08 AM 07/15/2022: nice first program :)
mr.penis on 1:59 PM 08/09/2024: strcpy(Str2, "07/10/97");
jeffli6789 on 5:21 AM 04/13/2025: This is not a malware. Some contributing factors for the false positive are 1) The file is an .exe compiled with GCC, 2) it carries large resources in the .rsrc section, but mainly it is just the pacman icon
