Fatmike on 2024-10-13 14:02: Good job @nightxyz. Are you also going to remove the dll?

nightxyz on 2024-10-13 17:08: I simply removed with cffexplorer but in x64dbg, i couldn't bypass. So, i decided not to struggle with more.

Fatmike on 2024-10-30 16:05: @Yanderome : Thanks a lot for your detailed solution! Very well written!

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.*
