nightxyz on 12:33 AM 11/04/2025: We used to avoid sharing crackme solutions with difficulty levels 1 or 2, even if we knew the solutions, to avoid discouraging newcomers. It's been a while since a crackme was released, but if someone still hasn't found the solution, then it's acceptable.
adenosinetp10 on 5:29 PM 11/21/2025: took me around 8 mins, but found the solution. People should stop sharing answers here in the comments to be honest.
Thank you for your attention to this matter.

rehub on 5:27 PM 12/06/2025: good! thanks for challenge!
Z3bra on 12:14 PM 12/17/2025: solved, thanks for challenge
nicolaspoersch on 12:54 PM 12/20/2025: I'm learning RE now and this challenge can be completed just with static analysis in the decompiler
here's the most important thing:
if (local_c == 0x2179
0x2179 is 8569 in decimal, if you are using ghidra it tells you the answer if you right click, great educational challenge!
Solution by SenorGPT on 6:01 AM 12/19/2025: Windows x86-64 crackme. Traced string references (e.g., `"Enter PIN:"`) in x64dbg back into `main`, identified the numeric PIN check, and patched/bypassed the failure path to reach the success branch and recover the correct input - 8569.
