More reason to avoid "cloud" storage.

In this slide from a National Security Agency presentation on “Google Cloud Exploitation,” a sketch shows where the “Public Internet” meets the internal “Google Cloud” where user data resides. Two engineers with close ties to Google exploded in profanity when they saw the drawing.
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, 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 — 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.
The infiltration is especially striking because the NSA, under a separate program known as PRISM, has front-door access to Google and Yahoo user accounts through a court-approved process.
The MUSCULAR project appears to be an unusually aggressive use of NSA tradecraft against flagship American companies. The agency is built for high-tech spying, with a wide range of digital tools, but it has not been known to use them routinely against U.S. companies.
In a statement, 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 only.”
“NSA applies Attorney General-approved processes to protect the privacy of U.S. persons — minimizing the likelihood of their information in our targeting, collection, processing, exploitation, retention, and dissemination,” it said.
In a statement, Google said it is “troubled by allegations of the government intercepting traffic between our data centers, and we are not aware of this activity.”
“We have long been concerned about the possibility of this kind of snooping, which is why we continue to extend encryption across more and more Google services and links,” the company said.
At Yahoo, a spokeswoman said, “We have strict controls in place to protect the security of our data centers, and we have not given access to our data centers to the NSA or to any other government agency.”
Under PRISM, the NSA gathers huge volumes of online communications records by legally compelling U.S. technology companies, including Yahoo and Google, to turn over any data that matches court-approved search terms. That program, which was first disclosed by The Washington Post and the Guardian newspaper in Britain, is authorized under Section 702 of the Foreign Intelligence Surveillance Act (FISA) and overseen by the Foreign Intelligence Surveillance Court (FISC).
