Snowden

The story of Edward Snowden has reminded us once again that even the walls have ears.

[D]isclosures about America's own focus on cyberweaponry – including American-led attacks on Iran's nuclear infrastructure and National Security Agency documents revealed in the trove taken by Edward J. Snowden, the former agency contractor – detail the degree to which the United States has engaged in what the intelligence world calls "cyberexploitation" of targets in China.

Evidence that the NSA was secretly building a vast database of U.S. telephone records - the who, the how, the when, and the where of millions of mobile calls - was the first and arguably the most explosive of the Snowden revelations published by the Guardian newspaper in 2013.
