Snowden: I Left the NSA Clues, But They Couldnt Find Them

If the NSA still doesnt know the full extent of the greatest leak of secrets in its history, its not because of Edward Snowdens attempts to cover his tracks. On the contrary, the NSAs most prolific whistleblower now claims he purposefully left a trail of digital bread crumbs designed to lead the agency directly to the files hed copied.
In a WIRED interview published today, the 31-year-old megaleaker has revealed that he planted hints on NSA networks that were intended to show which of its documents hed smuggled out among the much larger set he accessed or could have accessed. Those hints, he says, were intended to make clear his role as a whistleblower rather than a foreign spy, and to allow the agency time to minimize the national security risks created by the documents public release.
The fact that NSA officials have told the press that his haul may have been as large as 1.7 million documents, says Snowden, is a sign that the agency has either purposely inflated the size of his leak or lacks the forensic skills to see the clues he left for its auditors. I figured they would have a hard time, Snowden tells WIRED, describing the agencys attempts to reverse-engineer his leak. I didnt figure they would be completely incapable.
In a speech late last year, NSA director Keith Alexander said that Snowden had given reporters between 50,000 and 200,000 documents. But in later statements to the press, NSA officials have said only that Snowden accessed 1.7 million documents, without specifying how much of that access was part of his authorized NSA duties. And Alexander also admitted in an interview after his resignation that the NSA still doesnt know the full extent of Snowdens leak. Indeed, an agency official said in a 60 Minutes interview that its post-leak investigation removed from the NSAs classified network every computer Snowden could have ever accessed, at a cost of tens of millions of dollars, for fear that he might have planted spyware on the machines for future data collection.
