GCHQ intercepts Google, Yahoo cloud data hosted in Britain, feeds info to NSA
The National Security Agency is fed internal information from Google and Yahoo’s private networks by British counterpart GCHQ, which intercepts communications traveling between company data centers based in Britain. ● Documents supplied by former NSA contractor Edward Snowden and reported by The Washington Post last Wednesday showed how the NSA and GCHQ work together to intercept private links that connect Google and Yahoo global data centers. On Monday, The Post added new background and details of a program known as “MUSCULAR” to its previous report to paint a more succinct picture of how the spy agencies access these supposedly protected data links.
