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");
