As we highlighted yesterday, reporters who conducted an analysis of the NSA’s “deep packet inspection” rules discovered that the federal agency was placing people in an “extremists” database simply for searching for information about Tor and Tails, an anonymous browser and a privacy-friendly operating system.
Although the authors did not specify the source of the revelation (for obvious reasons), Schneier believes the information could have been provided by a new whistleblower.
“I do not believe that this came from the Snowden documents. I also don’t believe the TAO catalog came from the Snowden documents. I think there’s a second leaker out there,” wrote Schneier on his blog.
Journalist Glenn Greenwald, who has worked closely with Edward Snowden in reporting on leaked NSA documents over the past year, appeared to agree with Schneier, tweeting, “Seems clear at this point.”
It remains to be seen whether this alleged second leaker will follow in the footsteps of Snowden and reveal his true identify, or whether he will choose to remain in the shadows, but the potential emergence of a new whistleblower represents a major headache for the NSA.
