An Eye On Your Internet Downloads

 Another story from the Snowden documents:

According to the documents, the LEVITATION program can monitor downloads in several countries across Europe, the Middle East, North Africa, and North America. It is led by the Communications Security Establishment, or CSE, Canada's equivalent of the NSA. (The Canadian agency was formerly known as "CSEC" until a recent name change.)

CSE finds some 350 "interesting" downloads each month, the presentation notes, a number that amounts to less than 0.0001 per cent of the total collected data.
The agency stores details about downloads and uploads to and from 102 different popular file-sharing websites, according to the 2012 document, which describes the collected records as "free file upload," or FFU, "events."
