How to detect (inside) if my Qt app is running on a virtual machine

[Lemat]

I developed a software on Qt Creator with c++ and i would want to write a code in c++ to detect if it is executed on virtual machine for security reason.

Hi,

Can you show the code matching your query ?

[Lemat]

@SGaist
i don't have a code yet, i am searching, that can be a function who check if my app is executing on virtual machine.

hi @Lemat and welcome

that is not an easy task, and as far as I know, you would have to code that specific for all the different VM's

you can take a look here
https://www.codeproject.com/Articles/9823/Detect-if-your-program-is-running-inside-a-Virtual

for an example for VMWare detection

@J-Hilk thanks for you reply. okay i understand and i will continue searching.

@Lemat If you virtual machine is a Windows system, you can read the manufacturer and model and look if it contains VMware or VirtualBox:

wmic computersystem manufacturer,name

@KroMignon

I don't have access to HyperV... but just try it out, open a cmd.exe and look at the result of wmic computersystem manufacturer,name

@KroMignon thanks, i will run it through QProcess.

Yes something like this should do the job:

QProcess wmic;

wmic.setProcessChannelMode(QProcess::MergedChannels);
wmic.start("wmic", QStringList() << "computersystem" << "get" << "manufacturer,name");
if(wmic.waitForFinished(10000))
{
    QString text(wmic.readAll());
    bool isVM = text.contains("VMware") || text.contains("VirtualBox") || text.contains("Virtual Machine");
    qDebug() << text;
}

@KroMignon , Yes. thanks a lot for you help.
