Verify the Whonix ™ Images

It is important to check the integrity of the downloaded virtual machine images to ensure that neither a man-in-the-middle attack or file corruption occurred (see Download Security).

Ambox warning pn.svg.png Warning:

Do not continue if verification fails! This risks using infected or erroneous files! The whole point of verification is to confirm file integrity.

Whonix virtual machine images are cryptographically signed by Whonix developer Patrick Schleizer using OpenPGP. [6]

If you know how to use an OpenPGP key, download the Whonix Signing Key and the Whonix signatures straight away.

Otherwise, use the following instructions:

Download Whonix ™ XFCE

2. Install VirtualBox Virtualbox logo.png

  • Linux Tux.png: please press expand on the right side.

Hosts using a non-Debian OS:

Install VirtualBox as per the normal mechanism for your Linux distribution.

Debian hosts:

These instructions are for Debian buster, which is recommended. Other Debian releases might work, but this is untested. In that case, replace buster with the actual codename your release.

Note: this applies to Whonix 15. Later Whonix versions may use a codename different to buster.

Package virtualbox should be installed from Debian unstable (codename: sid). This is non-ideal but required since VirtualBox in unavailable in Debian buster / buster-backports at the time of writing. It has risks such as bricking the apt package manager. Therefore users should make sure to have their backup and restore process functional. Alternativly you could install from Oracle Repository but this comes with different risks.

1. On the host.

Open a terminal.

2. Add Debian stable codename buster to the apt-conf default-release. 

sudo su -c "echo -e 'APT::Default-Release buster;' > /etc/apt/apt.conf.d/70defaultrelease"

3. Add Debian sid to Debian apt sources.

[7] 

sudo su -c "echo -e 'deb http://http.debian.net/debian sid main contrib non-free' > /etc/apt/sources.list.d/unstable.list"

4. Update the package lists. 

sudo apt-get update

5. Install the selected software. 

sudo apt-get install virtualbox/sid linux-headers-$(uname -r)

The procedure is now complete.

6. Undo.

On occasion it is necessary to undo this configuration, for example when upgrading from Debian buster to bullseye. [8] To proceed, run. 

sudo rm /etc/apt/sources.list.d/unstable.list

3. Import Whonix Whonix old logo.png into VirtualBox Virtualbox logo.png

5. VirtualBox Screen Resolution Bug

Cli4.png

If the display presents like the image on the right-hand side, then you are affected by a screen resolution bug which only occurs in the XFCE version of Whonix in VirtualBox. To correct the resolution, apply the following workaround.

  1. Maximize the window.
  2. VirtualBox VM Windows → View → Virtual Screen 1 → Choose any, resize to another resolution
  3. VirtualBox VM Windows → View → Auto-resize Guest Display

Footnotes and Experimental Spectre / Meltdown Defenses

Please press on expand on the right.

VirtualBox Stable Version | VirtualBox Testers Only Version

Testers only! For more information please press on expand on the right.

These experimental Spectre/Meltdown defenses are related to issues outlined in Firmware Security and Updates. Due to the huge performance penalty and unclear security benefits of applying these changes, it may not be worth the effort. The reason is VirtualBox is still likely vulnerable, even after:

  1. A host microcode upgrade.
  2. A host kernel upgrade.
  3. A VM kernel upgrade.
  4. A "not vulnerable" result from spectre-meltdown-checker run on the host.
  5. Installation of the latest VirtualBox version. [10]
  6. All Spectre/Meltdown-related VirtualBox settings are tuned for better security as documented below.

To learn more, see: VirtualBox 5.2.18 vulnerable to spectre/meltdown despite microcode being installed and the associated VirtualBox forum discussion. [11] Users must patiently wait for VirtualBox developers to fix this bug.

On the host. [12] [13] [14] [15] [16] [17] [18]

VBoxManage modifyvm "Whonix-Workstation" --spec-ctrl on
VBoxManage modifyvm "Whonix-Gateway" --nestedpaging off
VBoxManage modifyvm "Whonix-Workstation" --nestedpaging off

Info These steps must be repeated for every Whonix or non-Whonix VirtualBox VM, including multiple and custom VMs.

The above instructions only apply to the default VM names Whonix-Gateway ™ and Whonix-Workstation ™. Therefore, if Multiple Whonix-Workstation ™s and/or Multiple Whonix-Gateway ™s are configured, then repeat these instructions using the relevant name/s.

  2. ↑ https://forums.whonix.org/t/whonix-kvm-14-0-1-4-4-unified-tar-gz-download-point-release/7061
  3. ↑ This change reduces the number of steps users are required to apply (one download instead of two). No functionality was lost. This improves usability, makes Whonix downloads more standardized compared to other software, and simplifies Whonix infrastructure maintenance work. The Whonix split VM design (separate Whonix-Gateway ™ and Whonix-Workstation ™) remains unmodified.
  4. ↑ 4.0 4.1 4.2 4.3 By using the Tor Browser Bundle (TBB). For an introduction, see Tor Browser. See also Hide Tor and Whonix from your ISP.
  5. ↑ It does not matter if the bulk download is done over an insecure channel if OpenPGP verification is used at the end.
  6. ↑ OpenPGP is a standard for data encryption that provides cryptographic privacy and authentication through the use of keys owned by its users.

  10. ↑ VirtualBox version 5.2.18 or above is required since only that version comes with Spectre/Meltdown defenses. See https://forums.whonix.org/t/whonix-vulerable-due-to-missing-processor-microcode-packages/5739/22.

  12. ↑

    --ibpb-on-vm-[enter|exit] on|off: Enables flushing of the indirect branch prediction buffers on every VM enter or exit respectively. This could be enabled by users overly worried about possible spectre attacks by the VM. Please note that these options may have sever impact on performance.
    https://www.virtualbox.org/manual/ch08.html

    There is a mistake in the VirtualBox manual stating enter which does not work. It is actually entry.

  13. ↑ https://www.virtualbox.org/manual/ch08.html

    --l1d-flush-on-vm-enter on|off: Enables flushing of the level 1 data cache on VM enter. See Section 13.4.1, “CVE-2018-3646”.

  14. ↑

    --l1d-flush-on-sched on|off: Enables flushing of the level 1 data cache on scheduling EMT for guest execution. See Section 13.4.1, “CVE-2018-3646”.
    https://www.virtualbox.org/manual/ch08.html

  15. ↑ https://www.virtualbox.org/manual/ch13.html#sec-rec-cve-2018-3646

    For users not concerned by this security issue, the default mitigation can be disabled using

    VBoxManage modifyvm name --l1d-flush-on-sched off

    Since we want to enable the security feature we set --l1d-flush-on-sched on.

  16. ↑

    --spec-ctrl on|off: This setting enables/disables exposing speculation control interfaces to the guest, provided they are available on the host. Depending on the host CPU and workload, enabling speculation control may significantly reduce performance.
    https://www.virtualbox.org/manual/ch08.html

  17. ↑ According to this VirtualBox ticket --spec-ctrl should be set to on.
  18. ↑

    --nestedpaging on|off: If hardware virtualization is enabled, this additional setting enables or disables the use of the nested paging feature in the processor of your host system; see Section 10.7, “Nested paging and VPIDs” and Section 13.4.1, “CVE-2018-3646”.
