NSA documents leaked by Edward Snowden to the Guardian in 2013 described a covert program called XKEYSCORE (XKS) and showed how the US government can see almost everything one does on the internet; the new portion of the classified files published by The Intercept now reveals how easily it can be done: “as easy as typing a few words in Google.”
XKEYSCORE was one of the first covert programs that the Guardian wrote about when Snowden began leaking NSA documents two years ago, in 2013.
