VirtualBox + VPN with Win10 Host – how secure is it?

I got a notebook from my company running windows 10 which i am officially allowed to use privately. I have to travel a lot i don’t want to carry a second notebook. Since the admins are having access to the device, like for company administered browsers oder updates or whatever, i don’t want to use it without an extra layer of protection.

So i installed a VBox with a mint guest. The virtual drive is encrypted. Inside the guest system i installed mullvad vpn.

How safe is this setup? Is there any possibility to check if there is maybe a keylogger or something like that running in the host system compromising my security? Where are the potential pitfalls of this setup?

I don’t want to use it for illegal things (of course) but i don’t want my company to be able to read private mails, chats, know my account balance when i check my credit card bill abroad, see what i watch on netflix or whatever, see what i shopped and stuff like that. (Or see that i type this 😉 )

What’s your opinion on that?

Thank you and best regards

What’s the safest tool for running not safe soft – VirtualBox vs Windows Sandbox vs Hyper-V

I’d want to ask what’s the safest environment to run potentially not safe software?

I’m aware that this question may be very tricky, because every of those may have its flaws, but generally speaking which of those 3 sounds like safest option?

Hyper V – Windows 10 as host & guest

Virtualbox – Windows 10 as host & guest

Windows Sandbox?

Run Phone Apps in VM Anonymously and Security Risks of Virtualbox

Would it be possible to run phone apps that connect to the internet (eg. youtube, instagram, etc.) on an Android VM (or any sort of phone VM, doesn’t need to be android) in VirtualBox within a host OS such as Tails or Whonix so that they can be run at least pseudonymously? I was thinking using the android ISO.

I’m just concerned that this might not be anonymous enough and that there might be serious security issues with android in a VM.

One possible issue might be that VirtualBox is pretty vulnerable. However, as I understand it, the risk is mitigated if I run a VirtualBox inside a system that funnels all traffic through Tor–then there is little risk an attacker could see my IP correct? Are there other implications regarding VirtualBox vulnerability?

Any relevant responses would be greatly appreciated!

VirtualBox LAMP Server to Proxmox causes webroot to disappear

Hey guys! First time here.
Hopefully I'm in the right spot, move this thread if not.

I'm having some problems when trying to transfer my completely functional website thats hosted on my Virtualbox VM LAMP Server onto a Proxmox installation.
Let me explain.
I've had my first website up for about two months now. I'm running it on a Ubuntu Server 18.04 LAMP stack in a VirtualBox VM on Windows 10. I have my own GoDaddy signed certs so my site has https. I wanted to transfer this to My Proxmox…

VirtualBox LAMP Server to Proxmox causes webroot to disappear

Black Screen with cursor blinking when started Ubuntu on VirtualBox

Ubuntu on my Virtual Machine was running fine when I restarted then suddenly it starts showing a black screen. I googled and tried multiple solutions like:

  1. by disabling the “Enable 3D acceleration” on virtualBox settings
  2. Enabling the “Intel Virtualization Technology” from BIOS

Please note, when I used backup Ubuntu, it works fine. My host system is Ubuntu 18.04.3 LTS. VirtualBox Version 6.0.12, Ubuntu guest OS in VirtualBox is 18.04.2.

I will appreciate if you can help to address the issue

ubuntu 18.04 guests which cloned by virtualbox have the same ip but different mac address in NAT net work

I tried to build a group of Virtual machine in Virtualbox, and connect them with NAT network. The main information shows as below:

The Virtualbox version: 6.0.12 The Ubuntu guest version: ubuntu-18.04.2 The NAT network info: NetworkName: natnet22 IP: 192.168.13.1 Network: 192.168.13.0/24 IPv6 Enabled: No IPv6 Prefix: fd17:625c:f037:2::/64 DHCP Enabled: Yes Enabled: Yes loopback mappings (ipv4) 127.0.0.1=2

When i finish creating an Ubuntu machine, the DHCP server maybe assign ip 192.168.13.4 for it. But when I cloned the machine and I change the mac address of the cloned one. The DHCP server still assign ip 192.168.13.4 for the cloned one.

Why the cloned Ubuntu one get the same ip with source? I need them have different ip in the NAT network to control them. Please help me solve the problem.

Suppose you have a simple host running Virtualbox with NAT networking and do malware testing on it, how safe are you?

So, just a single windows host attached to the router and a virtual machine running on it. No shared folders or clipboard. Just testing your average malware.

Note that this question talks about just a single PC connected to a router, without any fancy file sharing enabled via network (It can have stuff like torrents and download managers, but not anything like a shared folder in the network).
