Whonix ™ 15 Changelog
Whonix ™ 15 was released on July 1, 2019.  Significantly, Whonix ™ 15 is based on the Debian buster (Debian 10) distribution which was officially released on July 6, 2019 instead of Debian stretch (Debian 9). The buster release has nearly 60,000 packages and over 62 per cent of them were updated   -- see the official Debian 10 release notes to learn more.
- Fixed file saving issues in scurl wrappers.   
- Fixed the partial truncation of text in Whonix Connection Wizard. 
- Installed cryptsetup by default so errors do not appear when using a GUI and interacting with encrypted containers.   
- Ported the build script to cowbuilder; build packages in chroot and use mmdebstrap for better security. 
- Modified whonixcheck so it suggests to start networking / onion-grater if it is not running. 
- Improved the /usr/share/sdwdate/unit_test  
- Improved the sdwdate message Tor consensus message. 
- Confirmed the sanity of systemd DNS after porting to Debian buster. 
- Established sane built-in defaults even if configuration files are non-existing.  
- Updated the onion list time sources for sdwdate so that offline and unwanted onions were removed. 
Improved Functionality and Usability
- Ported Whonix ™ from Debian stretch to Debian buster. 
- Added the qTox instant messaging application by default. 
- Install Firejail and Firetools by default inside Whonix ™.  
- Added the Metadata anonymisation toolkit v2 (MAT2) by default.   
- Added a LUKS container GUI (zulucrypt-gui)  by default to make management and creation of containers easy.  
- OnionShare is now installed by default for easier, anonymous sharing of files.  
- Added KeePassXC as the default Password Manager in Whonix-Workstation. 
- Removed the Richochet instant messaging application since it is no longer working in Whonix ™ 15.  
- Nyx has replaced tor-arm as the Tor controller, providing (slightly) better functionality and usability.  
- Set VLC X11 video decoding by default so it works more reliably and avoids known problems. 
- The Jitter RNG Daemon (jitterentropy) is now installed by default to improve randomness if entropy on the system runs low.  
- Significantly reduced the size of Non-Qubes-Whonix images using zerofree. 
Improved Functionality and Usability
- Added grub-live Whonix ™ Live-mode as a default package.     
- Added a description to whonix-vbox images.   
- Implemented Whonix KVM serial console support. 
- Disabled boot devices and modified audio settings in VirtualBox Workstation and Gateway to improve security.  
- Forked the kloak - Keystroke Anonymization Tool and installed it by default in Non-Qubes-Whonix.  
- Improved the default kernel hardening options for better security.   
- Correctly configured Qubes-Whonix ™ XFCE default start menu entries (whitelisted appmenus). 
- Created Qubes-Whonix 15 template configuration files.  
- Confirmed the Whonix-15-gateway template builds. 
Improved Functionality and Usability
- Simplified instructions for VM kernel in Qubes-Whonix ™ by installing the same recommended Qubes packages as Qubes Debian packages.  
- In DisposableVMs, tb-updater / tb-starter was modified to no longer copy Tor Browser to the user home directory at first boot -- /var/cache/tb-binary is now directly used to improve startup performance.  
- Some fixes/changes were implemented in both Whonix ™ 14 and 15.
- More than 91 per cent of the source packages included in Debian 10 are reproducible (will build bit-for-bit identical binary packages).
- A few fixes were needed, such as:
--remote-nameand replace it with
- Improve download wrappers and add
- For instance, an error would otherwise appear when using XFCE file manager with encrypted USBs.
- Make it simpler (to split urls into chunks of 3).
- Generate average, total etc. for each pool.
- Add curl command for the failures (timeouts).
- This was completed for whonix-gw-firewall, whonix-ws-firewall, whonixcheck, sdwdate, uwt, onion-grater (Control Port Filter Proxy), rads, open-link-confirmation, tb-starter, tb-updater and anon-ws-disable-stacked-tor.
MAT2 only removes metadata from your files, it does not anonymise their content, nor can it handle watermarking, steganography, or any too custom metadata field/system.
- zulumount-gui is also installed.
- Primarily due to incompatibility with v3 onions.
- nyx is actually the same project; just the name has changed and the presentation is very similar.
Using the Jitter RNG core, the rngd provides an entropy source that feeds into the Linux /dev/random device if its entropy runs low. ... Especially during boot time, when the entropy of Linux is low, the Jitter RNGd provides a source of sufficient entropy.
- This means Non-Qubes-Whonix users can boot into live-mode out of the box, without needing to install it.
- Such as the root password, Whonix ™ home page and so on.
- The floppy and optical settings were disabled in both the Gateway and Workstation, while the Gateway audio was also disabled.
kloak is a privacy tool that makes keystroke biometrics less effective. This is accomplished by obfuscating the time intervals between key press and release events, which are typically used for identification. This project is experimental.
- See recent pull requests here.
- The specific changes include:
Kernel symbols in /proc/kallsyms are hidden to prevent malware from reading them and using them to learn more about what to attack on your system.
Kexec is disabled as it can be used for live patching of the running kernel.
The BPF JIT compiler is restricted to the root user and is hardened.
ASLR effectiveness for mmap is increased.
The ptrace system call is restricted to the root user only.
The TCP/IP stack is hardened.
This package makes some data spoofing attacks harder.
SACK is disabled as it is commonly exploited and is rarely used.
This package disables the merging of slabs of similar sizes to prevent an attacker from exploiting them.
Sanity checks, redzoning, and memory poisoning are enabled.
The kernel now panics on uncorrectable errors in ECC memory which could be exploited.
Kernel Page Table Isolation is enabled to mitigate Meltdown and increase KASLR effectiveness.
SMT is disabled as it can be used to exploit the MDS vulnerability.
All mitigations for the MDS vulnerability are enabled.
DCCP, SCTP, TIPC and RDS are blacklisted as they are rarely used and may have unknown vulnerabilities.
- Neither are backups of Tor Browser maintained anymore; previously three backups were stored.
- timesync-fail-closed means sdwdate did not succeed yet. Networking for all but Tor and sdwdate should still be locked in this scenario.
