Historyedit

Tails was first released on 23 June 2009 It is the next iteration of development on Incognito, a Gentoo-based Linux distribution8 The Tor Project has provided financial support for its development7 Tails has also received funding from the Debian Project, Mozilla, and the Freedom of the Press Foundation9

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 Snowden101112

On 3 July 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"1314

On 28 December 2014, Der Spiegel published slides from an internal NSA presentation dating to June 2012 in which the NSA deemed Tails on its own as a "major threat" to its mission, and when used in conjunction with other privacy tools such as OTR, Cspace, RedPhone, and TrueCrypt was ranked as "catastrophic," leading to a "near-total loss/lack of insight to target communications, presence"1516
