Firejail worsens security by acting as a privilege escalation hole - Firejail requires being setuid, meaning that it executes with the privileges of the executable's owner which in this case, is the root user. Further, Whonix ™ developer madaidan has noted: įirejail is another common sandboxing technology however, it is also insufficient. While it can be used to restrict Tor Browser, Firefox-ESR, VLC and other regularly used applications, this comes with an increased fingerprinting risk. Firejail įirejail should be used with caution. The profiles are easy to apply and provide a considerable security benefit. It is recommended to enable the Whonix ™ AppArmor profiles which are available for various applications that are run in either the Whonix-Gateway ™ or Whonix-Workstation ™, such as Tor, Tor Browser, Thunderbird and others. Periodically delete the Whonix-Workstation ™ AppVM(s) and create fresh instances from the Whonix-Workstation ™ Template.Use DisposableVMs for all Internet activity or.See the multiple VM Snapshots recommendation below. This way it is possible to 'rollback' - use a new clean clone / snapshot VM - after risky activity or if a system compromise is suspected. Periodically delete old snapshots / clones.Only use the snapshots / clones for Internet activity.Make snapshots / clones of the master copy.Keep a clean master copy of the Whonix-Workstation ™ VM.The IP address is never leaked since this requires a compromise of the Whonix-Gateway ™ ( sys-whonix) VM, but this information may still result in identity disclosure. If the Whonix-Workstation ™ ( anon-whonix) VM is ever compromised, the attacker has access to the data it contains, including all credentials, browser data and passwords. To use a customized Whonix-Workstation ™ VM based on other operating systems, see here.
