Description

The goal here is to write a keygen. Don't patch the file if possible. This is the second crackme that I've ever written. I learned C++ recently only to write crackmes. So I'd appreciate suggestions. Thank you :)

dkaplan17 on 2023-02-20 10:52: @uncatchable I also noticed that. It's a false-positive on the AV's side. It most likely detects the file as a virus because similar blocks of code was seen on existing virusses. But I can assure you that this file is safe :) I can evem send you the source code on Discord if you want. Here's my tag: marcy.#2592

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.*
