A redaction oversight by the US government has finally confirmed that the Federal Bureau of Investigation’s targeting of secure email service Lavabit was used specifically to spy on Edward Snowden.



Ladar Levison, creator of the email service, which was founded on a basis of private communications secured by encryption and had 410,000 users, was served a sealed order in 2013 forcing him to aid the FBI in its surveillance of Snowden.



Levison was ordered to install a surveillance package on his company’s servers and later to turn over Lavabit’s encryption keys so that it would give the FBI the ability to read the most secure messages that the company offered. He was also ordered not to disclose the fact to third-parties.



After 38 days of legal fighting, a court appearance, subpoena, appeals and being found in contempt of court, Levison abruptly shuttered Lavabit citing government interference and stating that he would not become “complicit in crimes against the American people”.

We now know that reports of Snowden’s use of Lavabit for his secure communications were true and that, as most presumed, the reason the FBI drove Lavabit into closure was to surveil the leaker of the NSA files.

Documents obtained from the federal court were published by transparency organisation Cryptome, as noted by Wired’s Kim Zetter, revealing that “Ed_Snowden@lavabit.com” was the intended target of the action against Lavabit.

The documents were released after legal action from Levison, who has been fighting in an attempt to lift himself from his order of silence and reveal what really happened. A motion filed in December prompted the court to order the release of files within the case, specifically with the identity of the subscriber redacted.

As the documents show, that didn’t happen. Snowden’s email address was left unredacted, and while Levison is still under order not to reveal who the FBI was after, the redaction error has confirmed Snowden as the target.
