NSA collects millions of overseas emails

WASHINGTON — The National Security Agency is harvesting hundreds of millions of contact lists from personal email and instant messaging accounts around the world, many of them belonging to Americans, the Washington Post reported Monday, citing unnamed intelligence officials and top secret documents provided by former NSA contractor Edward Snowden.

The collection program, which has not been disclosed before, intercepts email address books and "buddy lists" from instant messaging services as they move across global data links. Online services often transmit those contacts when a user logs on, composes a message, or synchronizes a computer or mobile device with information stored on remote servers.

Rather than targeting individual users, the NSA is gathering contact lists in large numbers that amount to a fraction of the world's email and instant messaging accounts. Analysis of that data enables the agency to search for hidden connections and map relationships within a much smaller universe of foreign intelligence targets.

During a single day last year, the NSA collected 444,743 email address books from Yahoo, 105,068 from Hotmail, 82,857 from Facebook, 33,697 from Gmail and 22,881 from unspecified other providers, according to an internal NSA PowerPoint presentation. Those figures, described as a typical daily intake in the document, correspond to a rate of more than 250 million per year.

Each day, the presentation said, the NSA collects contacts from an estimated 500,000 buddy lists on live-chat services as well as from the "in-box" displays of Web-based email accounts.

The collection depends on secret arrangements with foreign telecommunications companies or allied intelligence services in control of facilities that direct traffic along the Internet's main data routes.

Although the collection takes place overseas, two senior U.S. intelligence officials acknowledged that it sweeps in the contacts of many Americans.

A spokesman for the Office of the Director of National Intelligence, which oversees the NSA, said the agency "is focused on discovering and developing intelligence about valid foreign intelligence targets like terrorists, human traffickers and drug smugglers. We are not interested in personal information about ordinary Americans."

The spokesman, Shawn Turner, added that rules approved by the attorney general require the NSA to "minimize the acquisition, use, and dissemination" of information that identifies a U.S. citizen or permanent resident.

The NSA's collection of nearly all U.S. call records, under a separate program, has generated significant controversy since it was revealed in June. The NSA's director, Gen. Keith Alexander, has defended "bulk" collection as an essential counterterrorism and foreign intelligence tool.

The NSA has not been authorized by Congress or the special intelligence court that oversees foreign surveillance to collect contact lists in bulk, and intelligence officials said it would be illegal to do so from facilities in the United States. The officials spoke on the condition of anonymity to discuss a classified program.
