Secret code indicates NSA tracks users of privacy tools, report says

A NSA spying tool is configured to snoop on an array of privacy programs used by journalists and dissidents, according to an analysis of never-before-seen code leaked by an unknown source.

The code, published as part of investigation by two German broadcasters last week, contains tracking specifications for XKeyScore, a powerful NSA program that collects and sorts intercepted data.

XKeyScore came to light in documents leaked by former NSA contractor Edward Snowden, but some observers believe the latest information -- which adds greater detail on how the agency monitors people trying to protect their privacy online -- may have not come from the documents he passed to journalists.

The broadcasters, Norddeutscher Rundfunk and Westdeutscher Rundfunk, did not reveal their source for the code but claimed in a report that former NSA employees and experts "are convinced that the same code or similar code is still in use today,"

The report describes how the code enables XKeyScore to track users connected to The Onion Router, known as TOR, a network that encrypts data traffic through random servers in order to obscure identification of a web surfer.

TOR, a project initially started by the U.S. Navy, is considered a critical privacy enhancing tool and one that has hampered NSA surveillance in the past.

The report contends the NSA is monitoring two TOR servers in Germany. One is run by Sebastian Hahn, a 28-year-old computer science student at the University of Erlangen. The server, known as a Directory Authority, a critical part of TOR's infrastructure, supplies a list of relays in the network to computers connecting to the network.

The NSA's collection of metadata about people connecting to the server puts those people at risk, the report quoted Hahn as saying.

The NSA also tracks the use of non-public TOR relays, which are supplied to users upon request in countries known to actively block TOR relays, such as in China and Iran, the report said.
