NSA’s Auroragold.

Edward Snowden turned over most or all of the documents he had to Glenn Greenwald, formerly of the Guardian, now at his own publication The Intercept. Greenwald's still going through them. Hundreds of thousands of pages. Today Glenn revealed "Auroragold," by which NSA breaks into approximately 70% of cell phone networks worldwide. https://firstlook.org/theintercept/2014/12/04/nsa-auroragold-hack-cellphones/
