The NSA and it’s British counterpart, GCHQ, has jointly developed a tool called MUSCULAR, operated jointly to exploid data links and stalk the interweb. Using interception points that are obfuscated from public eye, the two surveillance giants are copying vast arrays of information from Valley data centers via a large expanse of fiber-optic cables.

In a statement, Google said it was “troubled by allegations of the government intercepting traffic between our data centers, and we are not aware of this activity.” 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.

”NSA documents about the effort refer directly to “full take,” “bulk access” and “high volume” operations on Yahoo and Google networks.
