The National Security Agency has secretly broken into the main communications links that connect Yahoo and Google data centers around the world, according to documents obtained from former NSA contractor Edward Snowden and interviews with knowledgeable officials.
By tapping those links, the agency has positioned itself to collect at will from hundreds of millions of user accounts, many of them belonging to Americans. The NSA does not keep everything it collects, but it keeps a lot.
According to a top-secret accounting dated Jan. 9, 2013, the NSA’s acquisitions directorate sends millions of records every day from Yahoo and Google internal networks to data warehouses at the agency’s headquarters at Fort Meade, Md. In the preceding 30 days, the report said, field collectors had processed and sent back 181,280,466 new records — including “metadata,” which would indicate who sent or received e-mails and when, as well as content such as text, audio and video.
The NSA’s principal tool to exploit the data links is a project called MUSCULAR, operated jointly with the agency’s British counterpart, the Government Communications Headquarters . From undisclosed interception points, the NSA and the GCHQ are copying entire data flows across fiber-optic cables that carry information between the data centers of the Silicon Valley giants.
