US agency taps all you do online
You've never heard of XKeyscore, but it definitely knows you. The National Security Agency's top-secret programme essentially makes available everything you've ever done on the Internet -- browsing history, searches, content of your emails, online chats, even your metadata -- all at the tap of the keyboard.
The Guardian exposed the programme on Wednesday in a follow-up piece to its groundbreaking report on the NSA's surveillance practices. Shortly after publication, Edward Snowden, a 29-year-old former Booz Allen Hamilton employee who worked for the NSA for four years, came forward as the source.
This latest revelation comes from XKeyscore training materials, which Snowden also provided to The Guardian. The NSA sums up the programme best: XKeyscore is its "widest reaching" system for developing intelligence from the Internet.
The programme gives analysts the ability to search through the entire database of your information without any prior authorisation -- no warrant, no court clearance, no signature on a dotted line. An analyst must simply complete a simple onscreen form, and seconds later, your online history is no longer private. The agency claims that XKeyscore covers "nearly everything a typical user does on the Internet."
As The Guardian points out, this programme crystallises one of Snowden's most infamous admissions from his video interview on June 10:
"I, sitting at my desk," said Snowden, could "wiretap anyone, from you or your accountant, to a federal judge or even the president, if I had a personal email."
While United States officials denied this claim, the XKeyscore programme, as the public understands it, proves Snowden's point. The law requires the NSA to obtain FISA warrants on US citizens, but this is pushed aside for Americans with foreign targets — and this programme gives the NSA the technology to do so. The training materials claim XKeyscore assisted in capturing 300 terrorists by 2008.
The Guardian article breaks down how the programme works with each activity, from email monitoring to chats and browsing history, and includes screenshots from the training materials.
The Guardian reached out to the NSA for comment prior to publication. The agency defended the programme, stressing that it was only used to legally obtain information about "legitimate foreign intelligence targets in response to requirements that our leaders need for information necessary to protect our nation and its interests."
"XKeyscore is used as a part of NSA's lawful foreign signals intelligence collection system," the agency said in its response. "Allegations of widespread, unchecked analyst access to NSA collection data are simply not true. Access to XKeyscore, as well as all of NSA's analytic tools, is limited to only those personnel who require access for their assigned tasks ... .
"In addition, there are multiple technical, manual and supervisory checks and balances within the system to prevent deliberate misuse from occurring. Every search by an NSA analyst is fully auditable, to ensure that they are proper and within the law. These types of programmes allow us to collect the information that enables us to perform our missions successfully -- to defend the nation and to protect US and allied troops abroad."
XKeyscore is the second black mark on the NSA's record in the past few weeks. The Guardian's first story uncovered PRISM, a highly controversial surveillance programme that reportedly allows the security agency to access the servers of major Internet organizations including Facebook, Google, Apple, Microsoft, Yahoo, YouTube and Skype, among others.
Snowden's information led to a public outcry for transparency, and the US government pushed to declassify more information about PRISM in an effort to paint a clearer picture about the programme.
