Hello All,

Today I discovered GYB, and promptly downloaded the .msi file for Windows after reading the necessary details on github.

File downloaded: gyb-1.95-windows-x86_64.msi

Now, immediatley after download, Windows defender displayed the Malware / trojan detected warning and deleted the downloaded file, further details can be seen in the attached screenshot.

Malware detected: Trojan:Win32/Malgent!MSR


I have not tried downloading the file again. However, suggestions and insights from you all would be appreciated in this regard.

Regards,
ANV

Windows Defender is worth every penny you pay for it. Slightly better than the worthless AV software you do pay for...

This is a false positive. Report it to MS and ignore it (yes I know that's a bad answer but MS makes it extremely hard to solve this).

I do have it on my todo list to sign GYB builds like GAM builds are now signed which seems to help here (and shows what useless junk AV software has become these days).

Hello Mr. Lee,

Thanks for the update. Appreciate it.

I do realize that such false positives are quite irritating, however, what spooked me was the summary that microsoft provides on their trojan description page:  "Trojan:Win32/Malgent!MSR is a malware strain used by Diamond Sleet, a North Korean state-sponsored threat actor, in its software hijacking campaigns. ...  Once the victim runs the software, DLL hijacking occurs, allowing the attacker to install a backdoor, enabling further payload execution and credential theft. "

Regards,
ANV
