I have a Linux machine running Kubuntu 20.10.
I have installed VirtualBox 6.1. I then created a virtual machine on which I have installed Windows 10.
Suppose an hacker enters in my Windows 10 guest.
Will he be able to see the files of my Kubuntu host (I mean, the files not in the shared folders, of course)?
How does the answer changes if on the guest machine I have the VirtualBox add-ons installed?
