NSA Infiltrates Links to Yahoo, Google Data Centers Worldwide, Snowden Documents Say

The Washington Post reported a fact claim that the NSA secretly tapped into the unencrypted links behind massive cloud networks from companies like Google and Yahoo. Evidences came from documents which were obtained from former NSA contractor Edward Snowden and  knowledgeable officials. As backing of the claim, in the preceding 30 days, field collectors of NSA had processed 181,280,466 “metadata”, including emails, videos and audio, from  millions of foreign and American citizens user accounts. In fact, not only the NSA itself took the operation, but the British GCHG joined the “MUSCULAR” operation as well. They relied on an unnamed telecommunications provider outside of the U.S. to offer secret access to a cable or Google and Yahoo servers. As rebuttals, White House officials and the Office of the Director of National Intelligence, which oversaw the NSA, declined to confirm, deny or explain why the agency infiltrated Google and Yahoo networks overseas. At the same time, officers of Google denied that they provided the government with access to their systems. Yahoo restated their strict controls in place to protect the security of their data centers as well.
