Good questionHow do I safely test malware in virtual box? I heard something about using a nat connection, can't remember. Any tips?
You should use a VPN though since otherwise malware can find out your home IP address.Honestly with all the virtual machine stuff I do at Uni and at home. I just have the virtual machine setup with NAT, having my main Antivirus (Trend Micro) updated and turned on, on my host. Nothing more to it. I have never encountered anything jumping from the VM to the host in the whole time I've been using a virtual machine.
That's not as much of a problem as it is your ISP whining about it and ordering you to clean your PC even though you know the PC is fine, but they don't know that.VirtualBox NAT allows access to network resources using the host computer's IP address, so it is essential that you protect your IP by using a VPN at host or VM level.
This is important to avoid that
malware can process your real IP.
It's not about it getting onto the host it's about criminals getting your IP address. But it is possible if you don't use a VPN that malware can transfer over the network - trust me it can happen. It is really quite stupid to not use a VPN.I've never had a problem with any malware getting onto my host.
