XKeyscore: From the more than 500 million data connections to which the NSA has access every month, around 182 million of them are collected with the spying tool XKeyscore. A week ago, SPIEGEL reported on the wide-reaching surveillance capabilities NSA analysts have through the system, based on a classified NSA presentation. The program also enables a "full take" of all unfiltered data over a period of several days -- meaning, not just metadata but also the content of online communications. The gathering of hundreds of millions of Germany-related data connections does not mean that all of the data will be analyzed and evaluated by means of XKeyscore. According to the NSA, this happens on a case-by-case basis.
Lopers: As explained in NSA documents, Lopers is a system that allows the agency to spy on telecommunications. It is purely software-based and applicable to traditional telephone networks ("Public Switched Telephone Network").
Juggernaut: This system picks up signals from mobile networks, including vocal telephone communication, fax, data and text messages.
