In the Guardian, Glenn Greenwald and Ewen MacAskill leak a description of another NSA top-secret program, this one codenamed "BOUNDLESSINFORMANT." This is apparently a tool that helps spies keep track of which snooping tools they can deploy in which countries, and it produces pretty, color-coded maps showing where the NSA spying powers are strongest. The Guardian has excellent notes on how this fits in with the ongoing fight between the US Senate and the NSA on whether and how the NSA spies on Americans:
The Boundless Informant documents show the agency collecting almost 3 billion pieces of intelligence from US computer networks over a 30-day period ending in March 2013. One document says it is designed to give NSA officials answers to questions like, "What type of coverage do we have on country X" in "near real-time by asking the SIGINT [signals intelligence] infrastructure."
An NSA factsheet about the program, acquired by the Guardian, says: "The tool allows users to select a country on a map and view the metadata volume and select details about the collections against that country."
Under the heading "Sample use cases", the factsheet also states the tool shows information including: "How many records (and what type) are collected against a particular country."
A snapshot of the Boundless Informant data, contained in a top secret NSA "global heat map" seen by the Guardian, shows that in March 2013 the agency collected 97bn pieces of intelligence from computer networks worldwide.
They quote Judith Emmel, an NSA spokesperson who says, "The continued publication of these allegations about highly classified issues, and other information taken out of context, makes it impossible to conduct a reasonable discussion on the merits of these programs." However, the NSA would not admit the existence of these programs (not even to the senate), prior to this.
