Description

The most ordinary crackme that accepts a password and displays the answer to you! But it's not that simple, try to find out what exactly checks the password and how it works! No obfuscation, no protectors, just a basic anti-debug system

voxydox on 2025-07-16 15:53: *v8++ = v2 ^ 0x5A; v2 = *v8; nice crackme

nightxyz on 2025-07-16 16:19: Excellent crackme. File has embedded DLL file. Die64 detects it. -----SPOILER----- Password : ******96 -----SPOILER-----

ultrazvukoff on 2025-07-16 21:40: good, i think its was be hard, i remake this

ultrazvukoff on 2025-07-16 21:52: nightxyz, was it too easy? just don't feel like adding different obfuscations and so on

nightxyz on 2025-07-17 02:44: @ultrazvukoff No, it was not too easy. In fact, this is the first time I've encountered a program that exits after a certain amount of time after calling fgets. Although I didn't fully understand how fgets triggered the function addressed by beginthread, I was able to debug it easily by bypassing it. It's a nice crackme. There are even methods that bypass ScyllaHide.

ultrazvukoff on 2025-07-17 09:08: @nightxyz, I'll make a new one tomorrow, but it will have some self-written protection that I'm making for my future project. I'll need to check it out.

scaredandalone on 2025-08-04 03:16: good crackme :D

XNOT21 on 2025-08-22 10:29: For people who want to patch it, you will find it harder than just trying to find the password https://imgur.com/a/DslMZiC
