Eavesdropping capability

Britain's electronic spying agency, in cooperation with the U.S. National Security Agency, hacked into the networks of a Dutch company to steal codes that allow both governments to seamlessly eavesdrop on mobile phones worldwide, according to the documents given to journalists by Edward Snowden.

A story about the documents posted Thursday on the website The Intercept offered no details on how the intelligence agencies employed the eavesdropping capability—providing no evidence, for example, that they misused it to spy on people who weren't valid intelligence targets.
