How to bypass the proctoring system?

I have an online exam in unique, through the OES (kz) platform. So she is a lot smarter, she follows you on the webcam, monitors the number of monitors, fixing attempts to copy and paste text, blocking the right mouse button, browser and desktop control, and so on.

You download a special extension that records the entire screen, microphone and webcam.

So, do you have any ideas how to bypass surveillance?) At least with a screen

As already suggested - write the exam itself in a virtual machine. Throw a webcam into it. Accordingly, you will have to fill the virtual machine itself under the guise of a regular PC (put wallpaper on the desktop there, throw folders and shortcuts)
Another question is the browser platform or the desktop one? If the desktop is a big chance to get burned that you are on a virtual machine. In the browser, the virtual machine will work with almost 100% probability
Further.
Looked at the OES website. There goes data analysis through AI. This is a very serious problem (it will not be possible to replace the recording from the webcam with a high probability)
From the functions:
Face recognition with an accuracy of> 99%
Fixing the turn of the head to the sides
Determining the absence and replacement of the user
Fixing the presence of unauthorized persons
Fixing extraneous noise and voice
Monitoring the browser and desktop
Checking the number of screens
Checking the health of the equipment
Fixing attempts to copy and paste text
Blocking the right mouse button
This is a very big problem. That is, you have to google very carefully. You yourself understand that if the light from the monitor hits your face, then its frequent change, together with the running of your eyes around the screen, will immediately tell you about cheating. As an option, change the angle of the monitor so that the light goes mainly to the ceiling somewhere. Reduce monitor brightness. In this case, the webcam will need to think about how to fix it more correctly.
At a minimum, you will need to attach a bad webcam to interfere with the behavior analysis system. You also need to create bright lighting in the room to minimize the paleness of the light from the monitor screen.
Next, think for yourself. Record a video from the webcam for 15 minutes as you write off something and try not to burn. Then look at the record and already draw a conclusion about paleness. In general, experiment.
As an option - do not write off and rely only on your knowledge)))

TC seems to be lucky - he passed. But not everyone is so lucky - https://habr.com/ru/news/t/596137/
This is exactly what I wrote about in the comments - no one will sniff with you. The system will require that it be provided with the conditions in which it will work - or it will refuse to work.

In short, I solved the problem very simply. :)
Made a browser that is not visible in the screenshots/screen recordings. And now, without pain, in one place, right on my PC, without any virtual machines and a second monitor / PC, I sit and google in my browser. :)
I plan to finalize and distribute. Thank you all for the advice, especially the witty ones)
