Description

..::[FaTmiKE 2o24]::.. Have fun with the remake of my first crackme from 2005! It is pretty easy to solve so it's also good for beginners. The goal is to find the valid serial. A window will pop up to let you know you found it :-) There is only one valid serial. Fatmike

hacktooth on 2024-10-07 12:54: i cant reverse the CRC32 algoritm :( any tips?

Fatmike on 2024-10-08 15:33: Spoiler: @hacktooth: I will give you 2 hints: 1.) You don't have to reverse the CRC32 algorithm 2.) Click the 'About' button and read the information carefully

hacktooth on 2024-10-09 00:11: Done !

CZ-DannyK on 2024-10-13 11:21: Uff, finally kicked its ass, took me longer than i would like to admit. My reversing skills are bit rusty after almost 20 years :D

Fatmike on 2024-10-13 14:01: Well done everybody! And welcome back @CZ-DannyK, i also had a long break until last year!

Tokyo13377 on 2024-10-14 02:15: Hello Fatmike I hope you see this is there anyway I could get the source of this crackme I would love to compare it to the output and see if some of my theories were correct while I was reversing it thank you

Fatmike on 2024-10-14 07:41: @Tokyo13377 : Just come to the crackmes.one discord channel, and ask your questions there or write me a pm!

jeffli6789 on 2026-01-04 06:25: This crackme had been reviewed when it was originally approved and is likely safe. Crackmes often get flagged by antivirus software, EDR systems, or VirusTotal because they may use the same protection techniques found in malware (packers, anti-debugging, self-modifying code, etc.), or simply a false positive. This does NOT mean the crackme is actually malicious. The only way to confirm whether something is truly malware is to reverse engineer it and find proof of malicious code and/or malicious behavior. If you still believe this is actual malware, please report it to us via email: crackmesone@gmail.com. **We encourage everyone to run crackmes in a VM (virtual machine) and exercise caution when executing unknown binaries.** *Disclaimer: We do our best to review submissions, but mistakes can happen. The administrators and crackmes.one cannot be held liable for any damages or losses resulting from the use of files downloaded from this site. Always exercise caution and use a sandboxed environment.*
