Tails or The Amnesic Incognito Live System is a security-focused Debian-based Linux distribution aimed at preserving privacy and anonymity.[3] All its outgoing connections are forced to go through Tor,[4] and direct (non-anonymous) connections are blocked. The system is designed to be booted as a live DVD or live USB, and will leave no trace (digital footprint) on the machine unless explicitly told to do so. The Tor Project has provided most of the financial support for its development.[5]

History

Tails was first released on June 23, 2009. It is the next iteration of development on Incognito, a Gentoo-based Linux distribution.[6] Most of the financial support for its development has been provided by the Tor Project.[5] Tails has also received funding from the Debian Project, Mozilla, and the Freedom of the Press Foundation.[7]

Laura Poitras, Glenn Greenwald, and Barton Gellman have each said that Tails was an important tool they used in their work with National Security Agency whistleblower Edward Snowden.[8][9][10]

On July 3, 2014, German public television channel Das Erste reported that the NSA's XKeyscore surveillance system contains definitions that match persons who search for Tails using a search engine or visit the Tails website. A comment in XKeyscore's source code calls Tails "a comsec mechanism advocated by extremists on extremist forums".[11][12]

  • Security fixes, bug fixes, and minor improvements to Debian

Old version, no longer supported: 1.2[18] 16 October 2014
  • Install (most of) the Tor Browser, replacing our previous Iceweasel-based browser. The version installed is from TBB 4.0 and is based on Firefox 31.2.0esr. This fixes the POODLE vulnerability.

  • Confine several important applications with AppArmor.
  • Install Linux 3.16-3 (version 3.16.5-1).
  • Upgrade I2P to 0.9.15, and isolate I2P traffic from the Tor Browser by adding a dedicated I2P Browser. Also, start I2P automatically upon network connection, when the i2p boot option is added.
  • Make it clear that TrueCrypt will be removed in Tails 1.2.1, and document how to open TrueCrypt volumes with cryptsetup.
  • Enable VirtualBox guest additions by default. In particular this enables VirtualBox's display management service.
  • Make the OTR status in Pidgin clearer thanks to the formatting toolbar.
  • Upgrade syslinux to 6.03-pre20, which should fix UEFI boot on some hardware

Most of the work put into this release will aim at reducing the workload of creating new versions of Tails through infrastructure improvements and automated testing. The developers' objective is to be able to release same-day security updates.[13]
Future release: 3.0 TBA
  • Will focus on changes in the internals of Tails to make it more secure. That includes sandboxing critical applications and software hardening.[13]
