NSA Hacks Yahoo, Google Data Centers
Via the Washington Post:
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 among 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, NSA’s acquisitions directorate sends millions of records every day from Yahoo and Google internal networks to data warehouses at the agency’s Fort Meade headquarters. In the preceding 30 days, the report said, field collectors had processed and sent back 181,280,466 new records — ranging from “metadata,” which would indicate who sent or received e-mails and when, to content such as text, audio and video.
As the Post notes, this program, called MUSCULAR, is unusual because while “the agency is built for high-tech spying, with a wide range of digital tools, [it] has not been known to use them routinely against US companies.”
In order to obtain free access to data center traffic, the NSA had to circumvent gold standard security measures. Google “goes to great lengths to protect the data and intellectual property in these centers,” according to one of the company’s blog posts, with tightly audited access controls, heat sensitive cameras, round-the-clock guards and biometric verification of identities.
Google and Yahoo also pay for premium data links, designed to be faster, more reliable and more secure. In recent years, each of them is said to have bought or leased thousands of miles of fiber optic cables for their own exclusive use. They had reason to think, insiders said, that their private, internal networks were safe from prying eyes.
