whoisl on 2023-11-21 14:33: I think that something is not right about the debugger security. I am new at this idk if there is a way to bypass that logic in the terminal.

Elvis on 2023-11-24 03:01: @Warning: Not really. 9/72 is pretty low detection rate. To analyze the binary, VirusTotal runs it in a sandbox and monitors every traffic connection. This includes traffic from the operating system itself, such as connections to the Microsoft time server to update the clock.

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.*

Relatively simple walkthrough. The debugger check is flawed and must be bypassed to run the challenge at all, however
