The ANT catalog[a] (or TAO catalog) is a classified product catalog by the U.S. National Security Agency (NSA) of which the version written in 2008–2009 was published by German news magazine Der Spiegel in December 2013. Forty-nine catalog pages[b] with pictures, diagrams and descriptions of espionage devices and spying software were published. The items are available to the Tailored Access Operations unit and are mostly targeted at products from US companies such as Apple, Cisco and Dell. The source is believed to be someone different than Edward Snowden, who is largely responsible for the global surveillance disclosures since 2013. Companies whose products could be compromised have denied any collaboration with the NSA in developing these capabilities.
Jacob Appelbaum co-authored the English publication in Der Spiegel with Christian Stöcker [de] and Judith Horchert, which was publicized on 29 December 2013.[1] The related English publication on the same day about the TAO by Der Spiegel was also authored by the same people, and including Laura Poitras, Marcel Rosenbach, Jörg Schindler [de] and Holger Stark [de].[5] On December 30, Appelbaum gave a lecture about "the militarization of the Internet" at the 30th Chaos Communication Congress in Hamburg, Germany.[6] At the end of his talk, he encouraged NSA employees to leak more documents.[7]
