Whonix ™ 15 Changelog[edit]

Whonix ™ 15 was released on July 1, 2019. [1] 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 [2] [3] -- see the official Debian 10 release notes [archive] to learn more.

All Platforms[edit]

Bug Fixes[edit]

  • Fixed file saving issues in scurl wrappers. [4] [5] [6]
  • Fixed the partial truncation of text in Whonix Connection Wizard. [7]
  • Installed cryptsetup by default so errors do not appear when using a GUI and interacting with encrypted containers. [8] [9] [10]


  • Ported the build script to cowbuilder; build packages in chroot and use mmdebstrap for better security. [11]


  • Modified whonixcheck so it suggests to start networking / onion-grater if it is not running. [12]
  • Improved the /usr/share/sdwdate/unit_test [13] [14]
  • Improved the sdwdate message Tor consensus message. [15]
  • Confirmed the sanity of systemd DNS after porting to Debian buster. [16]
  • Established sane built-in defaults even if configuration files are non-existing. [17] [18]
  • Updated the onion list time sources for sdwdate so that offline and unwanted onions were removed. [19]

Improved Functionality and Usability[edit]

Security Enhancements[edit]


Bug Fixes[edit]

  • Corrected a VirtualBox error related to guest utils not starting. [40] [41]


  • Significantly reduced the size of Non-Qubes-Whonix images using zerofree. [42]

Improved Functionality and Usability[edit]

Security Enhancements[edit]

Qubes-Whonix ™[edit]

Bug Fixes[edit]

  • Correctly configured Qubes-Whonix ™ Xfce default start menu entries (whitelisted appmenus). [59]


  • Created Qubes-Whonix 15 template configuration files. [60] [61]
  • Confirmed the Whonix-15-gateway template builds. [62]

Improved Functionality and Usability[edit]

  • Simplified instructions for VM kernel [archive] in Qubes-Whonix ™ by installing the same recommended Qubes packages as Qubes Debian packages. [63] [64]
  • 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. [65] [66]

Security Enhancements[edit]

  • Confirmed Qubes-Whonix ™ TemplateMVs cannot upgrade in timesync-fail-closed mode. [67] [68]

Whonix ™ 15 Updates[edit]

As Whonix ™ is now a rolling distribution, users will benefit from regular small security and usability improvements, features and bug fixes as they enter the Whonix ™ stable repository. Those will be announced here.

Info The majority of the enhancements below also also apply to Qubes-Whonix ™. Exceptions include:

Many of these will be possible once the use of in-VM kernels is simplified and promoted in Qubes OS. [70] [71]

All Platforms[edit]

In 2019, point releases were announced on 10 September, 22 and 23 November. [72] [73] [74] [75] In 2020, point releases were announced on 16 February, 27 February, 19 and 21 March, 29 May, 10 and 18 June, 27 August, 7 and 17 and 30 September, and 17 December. [76] [77] [78] [79] [80] [81] [82] [83] [84] [85] [86] [87] [88]

Notable changes are listed below. Note that an in-place upgrade is not recommended for KVM -- significant changes have been made to the host settings that require the current machines and virtual networks to be replaced with updated ones. Refer to the KVM wiki for detailed installation instructions.

  • Disabled vm.unprivileged_userfaultfd=0 because it is currently broken. [107] [108] [109]
  • pkexec wrapper: fixed gdebi / synaptic but at the cost of checking for passwordless sudo /etc/suders /etc/sudoers.d exceptions. [110]
  • SecBrowser / i2pbrowser: no longer use firejail by default even if installed since currently not maintained by anyone in Whonix / Kicksecure.
  • Fixed the i2pbrowser local browser homepage.
  • Fixed an onioncircuits error report related to user permissions. [111] [112]
  • Added an ENOUGH_RAM setting to swap-file-creator (1950 MB RAM default), so if there is enough RAM a swap file is not created (improving boot time). [113]

Kernel and Related Hardening[edit]

Significant kernel [archive] and other security hardening has been implemented; numerous enhancements have been made to security-misc [archive]: [172]

  • Enabled kernel panic on kernel oops after boot, see: set oops=panic kernel parameter or kernel.panic_on_oops=1 sysctl for better security [archive].
  • Enabled usergroups, so group permissions are the same as user permissions. [173]
  • Removed read, write and execute access for others for all users who have home folders under folder /home. [174] [175]
  • Group sudo membership is required to use su.
  • Passwordless, recovery / emergency mode has been implemented.
  • Lock user accounts with pam_tally2 after five failed authentication attempts are detected. [176]
  • Fix pam_tally2 check when read-only disk boots without ro-mode-init or grub-live.
  • The thunderbolt and firewire modules were blacklisted, since they can be used for Direct Memory Access (DMA) attacks.
  • Every module must now be signed before being loaded; any module that is unsigned or signed with an invalid key cannot be loaded. [177]
  • Uncommon network protocols were blacklisted: these are rarely used and may have unknown vulnerabilities. [178]
  • Enabled IOMMU [archive].
  • The SysRq key is restricted to only allow shutdowns/reboots.
  • Restrict [archive] the SysRq key so it can only be used for shutdowns and the Secure Attention Key.
  • A systemd service mounts /proc with hidepid=2 at boot, thereby preventing users from seeing each other’s processes.
  • A systemd service clears on boot as these contain kernel symbols that could be useful to an attacker. [179]
  • Remove after a kernel upgrade.
  • remove-system-map: use shred instead of rm.
  • The kernel logs are restricted to root only.
  • The BPF JIT compiler is restricted to the root user and is hardened.
  • The ptrace system call is restricted to the root user only.
  • Added user root to group sudo. This is necessary so it is still possible to login as a user in a virtual console. [180]
  • Kernel symbols in /proc/kallsyms are hidden. This prevents malware from reading and using them to learn more about system vulnerabilities that can be attacked.
  • Kexec is disabled because it can be used for live patching of the running kernel.
  • Bluetooth is blacklisted to reduce the attack surface.
  • Added experimental SUID Disabling and Permission Hardening: [181] [182]
    • A systemd service removes SUID / GUID from non-essential binaries as these are often used in privilege escalation attacks. [183]
  • Enables mitigations for the L1TF (L1 Terminal Fault) vulnerability. [184]
  • Unconditionally enable all kernel patches for CPU bugs (spectre, meltdown, L1TF and so on) -- this might reduce performance: [185] [186]
    • spectre_v2=on
    • spec_store_bypass_disable=on
    • tsx=off
    • tsx_async_abort=full,nosmt
  • The MSR kernel module is blacklisted to prevent CPU MSRs from being abused to write to arbitrary memory.
  • Vsyscalls are disabled as they are obsolete, are at fixed addresses and are a target for ROP.
  • Page allocator freelist randomization is enabled.
  • The vivid kernel module is blacklisted as it is only required for testing and has been the cause of multiple vulnerabilities.
  • An initramfs hook sets the sysctl values in /etc/sysctl.conf and /etc/sysctl.d before init is executed so sysctl hardening is enabled as early as possible.
  • The kernel panics on oopses to prevent it from continuing to run a flawed process and to deter brute forcing.
  • Improve entropy collection: [187] [188]
    • Load jitterentropy_rng kernel module.
    • Distrust the CPU for initial entropy at boot as it is not possible to audit, may contain weaknesses or a backdoor.
    • Disable trusting RDRAND.
    • random.trust_cpu=off
  • Experimental: remount /home, /tmp, /dev/shm and /run with nosuid,nodev (default) and noexec (opt-in). To disable this, see footnote. [189] [190] [191]
  • Fix xfce4-power-manager xfpm-power-backlight-helper pkexec lxsudo popup [archive].
  • Do show lxqt-sudo password prompt if there is a sudoers exception.
  • Improved pkexec wrapper logging.
  • Installation fix in the case when user user does not exist.
  • Better output if trying to login with a non-existing user.
  • Add user user to group console in Whonix and Kicksecure.
  • Lock user accounts after 50 rather than 100 failed login attempts [archive].
  • Disable the busmaster bit on all PCI bridges during very early boot to avoid holes in IOMMU. [192] [193] [194]
  • Only allow symlinks to be followed when outside of a world-writable sticky directory, or when the owner of the symlink and follower match, or when the directory owner matches the symlink’s owner. Prevent hardlinks from being created by users that do not have read/write access to the source file. These prevent many TOCTOU races:
    • fs.protected_symlinks=1
    • fs.protected_hardlinks=1
  • Restrict loading TTY line disciplines to CAP_SYS_MODULE to prevent unprivileged attackers from loading vulnerable line disciplines with the TIOCSETD ioctl which has been used in exploits before. [195] [196] [197]
  • For a full list of changes, see: [archive]


  • Command line control of KVM VMs is now supported. [198]
  • The microphone is disabled by default.
  • Switched RNG to /dev/urandom.
  • pvspinlock is enabled.
  • Fixed Whonix-Gateway firewall desktop shortcuts.
  • No longer install pulseaudio by default on Whonix-Gateway.
  • Various apparmor fixes.
  • Created new apparmor profiles for bootclockrandomization, permission lockdown, and pam tally2 information.
  • Ensured future compatibility for apparmor-profile-everything.
  • Improved the output of remove
  • Fixed the KVM prepare_release script.
  • Fixed the GPU tag in libvirt XML.
  • Updated Tor Browser to version 9.0.1, then later versions (9.5).
  • Fixed Kicksecure KVM’s broken networking.
  • Moved to [199]
  • Other platforms build fix.
  • monero-gui can be uninstalled.
  • Fixed /etc/resolv.conf.
  • Enabled export QMLSCENE_DEVICE=softwarecontext for KVM.
  • Upgraded to the 2020 Whonix logo version.
  • Upgraded monero-gui.

Security Enhancements[edit]

Much stronger Linux user account isolation has been enforced in Non-Qubes-Whonix ™: [200]

Added vanguards [archive] to protect against guard discovery and related traffic analysis attacks: [207] [208] [209]

  • The daemon in Tor through and 0.4.2.x through does not verify that a rendezvous node is known before attempting to connect to it, which might make it easier for remote attackers to discover circuit information -- vanguards fixes this [archive].
  • Use vanguards from [archive]
  • Ensured vanguards do not start in a TemplateVM in Qubes-Whonix.

Eased installation of Linux Kernel Runtime Guard (LKRG) for users of Non-Qubes-Whonix ™, Kicksecure and Debian hosts -- sudo apt install lkrg: [210] [211]

  • Improves overall system security and is compatible with tirdad.
  • Hardens kernel security by killing whole classes of exploits, detecting exploits and performing Linux kernel runtime integrity checking.
  • Worked with LKRG upstream to fix LKRG VirtualBox host support.
  • Packaging enhancements were incorporated, so any standard Debian build tool can be used. [212]
  • Disabled the “System is clean!” message to avoid spamming dmesg and tty1.
  • Fixed [archive] compilation using DKMS on kernel upgrade by adding support for make variable KERNELRELEASE (DKMS sets it).
  • Auto-load LKRG after installation. [213]
  • Upgraded LKRG to the latest upstream version (version 0.8.1; although not yet installed by default).

Other security enhancements:


  • Upgraded VirtualBox guest additions to version 6.1.14.
  • vm-config-dist: run vbox-guest-installer [archive] when package virtualbox-guest-additions-iso [archive] is updated.
  • VirtualBox 6.1.12 upgrade: [223]
  • Reverted to vmsvga grapics controller settings due to issues [archive].
  • Increased [archive] Whonix-Gateway default RAM to 1280 MB. Otherwise, VirtualBox guest additions kernel modules fail to compile.
  • Current VirtualBox screen resolution situation:
    • Functional VirtualBox VM Window → View → Virtual Screen 1 → resize to resolution
    • Functional VirtualBox VM Window → View → Adjust Window Size
    • A workaround to improve this situation is still required.
    • Added xserver-xorg-video-vmware to kicksecure-desktop-environment-essential-gui because it is required by VirtualBox Graphics Controller VMSVGA for auto resize and resize through VirtualBox settings menu.
    • Again set the VirtualBox Graphics Controller to VMSVGA (equivalent to “VirtualBox → click a VM → Settings → Display → Graphics Controller → VMSVGA → OK”). [225] [226]
    • Increased Whonix VirtualBox Whonix-Gateway video RAM to 128 MB since the previous assignment of only 16 MB RAM can cause resize issues.
    • Updated VirtualBox and VirtualBox guest addition to 6.1.4. The VirtualBox guest addition has been further upgraded to 6.1.6 in a later Whonix release.
  • Added a workaround for the bug causing the VirtualBox screen resolution to be too small; the screen resolution is now 1920x1080 by default for all VMs [archive].
  • Configured three (instead of four) virtual CPU cores by default as this can improve stability. [227]
  • Enabled the Debian stable-updates repository by default. [228]
  • Consolidated Whonix packages. [229]
  • Installed fewer unneeded packages such as rsyslog (see footnote). [230]
  • Unbreak VirtualBox clearnet DNS settings when not using DNSCrypt.

Website Improvements[edit]

  • Wiki editing over onion.
  • Using Whonix ™ forums over onion.
  • Mostly fixed onion forum site redirects to clearnet. [231]
  • Implemented the Onion-Location [archive] header, which shows the “onion available” message to any Tor Browser user visiting the clearnet version of
  • Fixed a false Mediawiki message that identified Whonix ™ forum logins as insecure over onion (thereby offering a https connection to the onion URL). [232] [233]
  • Implemented Expect-CT security header for [234]
  • Fixed URL with no onion mirror. [235]
  • Reviewed [archive] results (no clean HSTS-Preload / DNSSEC). [236]
  • Researched DANE TLSA (DNS-based Authentication of Named Entities) for [237]
  • Whonix software signature verification documentation discussion: VirtualBox vs KVM - GPG / signify / codecrypt. [238]
  • Checked broken discourse email replies. [239]
  • Investigated uploaded images not presenting after creating a topic. [240]
  • Documented Testing the Whonix ™ server with test websites such as / / Mozilla Observatory / SSL Labs /
  • Improved documentation chapter Trusting the Whonix ™ Website.
  • Considered drop-www vs yes-www.
  • Considered Hide Server IP.
  • Set up a dedicated server for Kicksecure, with dedicated domain, homepage, wiki and soon forums. [241]

  58. 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.

  132. In favor of sdwdate-gui. whonixcheck connectivity check code checks Tor as well as sdwdate. Due to slow Tor/onion speed it often times out. Improving that code is difficult, so sdwdate-gui is used instead as a solution that provides better visual feedback to users.

  156. Added compatibility [archive] with restrict hardware information to root for Live Mode Indicator Systray.
  157. Fixed Live Mode Indicator Systray [archive] to detect ro-mode-init.
  158. Packaging enhancements, no longer depend on genmkfile, fix, use same version number as upstream (2.0) [archive].
  159. Remove Whonix specificity [archive] (default config file) from onion-grater (Whitelisting filter for dangerous Tor control protocol commands).
  160. dsudo - add sudo askpass wrapper for automated testing [archive].
  161. This means as long as the password is set to changeme, it is possible to use dsudo and not be asked to enter the default password.
  162. Packaging enhancements, no longer depend on genmkfile, can be build using standard Debian packaging tools, apparmor enhancements [archive].
  163. Refactoring /usr/lib/qubes-whonix/init/network-proxy-setup [archive].

  166. This is a sane default that works with default /etc/hosts without generating warnings about a wrong hostname when using sudo. /etc/hostname is not managed by any configuration package and can be changed.
  167. This might be re-introduced later as an opt-in package, see: Use DNSCrypt by default in Kicksecure? (not Whonix!) [archive]
  168. See: enable Debian stable-updates repository by default [archive].

  173. By default, Debian utilizes User Private Groups (UPG) [archive]. Also see: /usr/share/pam-configs/usergroups-security-misc
  174. For example, this affects those running “chmod o-rwx /home/user” during package installation or an upgrade.
  175. This is only performed once for each folder in the parent /home folder, so users who wish to relax file permissions can do so. This action protects files in the user's home folder which were previously created with lax file permissions prior to the installation of this package.
  176. See: unlock instructions. This means it is possible to have short, easy-to-remember, "weak" passwords for the user user account, while still preventing compromised non-root users from bruteforcing it.
  177. This makes it harder to load a malicious module.
  178. See: /etc/modprobe.d/uncommon-network-protocols.conf

  210. Also available in Qubes OS Debian templates and Qubes-Whonix with use of an in-VM kernel.
  211. LKRG will likely be installed by default in Whonix and Kicksecure in one of the next stable releases.
  212. This is quick and easy. For example: “dpkg-buildpackage -b”
  213. Since LKRG now supports module parameters and VirtualBox host support [archive], it can be automatically started after installation since it would no longer kill VirtualBox VMs running on a host.
