The NSA ANT catalog is a 50-(NSA) Tailored Access Operations (TAO) by the Advanced Network Technology (ANT) Division to aid in cyber surveillance. Most devices are described as already operational and available to US nationals and members of the Five Eyes alliance. According to Der Spiegel, which released the catalog to the public on December 30, 2013, "The list reads like a mail-order catalog, one from which other NSA employees can order technologies from the ANT division for tapping their targets' data." The document was created in 2008.
Security researcher Jacob Appelbaum gave a speech at the Chaos Communications Congress in Hamburg, Germany, in which he detailed techniques that the simultaneously published Der Spiegel article he coauthored indicate the NSA uses in its surveillance efforts in the US and internationally.
The prices of the items in the catalog range from free (typically for software) to US$250,000.
