We are building a comprehensive archive and analysis project examining published documents leaked by Edward Snowden. Our methodology involves systematically reviewing each available document with particular attention to small details and information that has received little or no public attention since the initial 2013 disclosures. Throughout this process, we will publish posts highlighting interesting previously unreported findings. The main project will hopefully be complete and made public in mid-to-late 2026.
This is Part 1 of our "Going Through Snowden Documents" series.
Document: CNE Analysis in XKEYSCORE
Classification: TOP SECRET//COMINT//REL TO USA, AUS, CAN, GBR, NZL
Date: October 15, 2009
Published by: The Intercept (July 1 and July 2, 2015)
Authors: Morgan Marquis-Boire, Glenn Greenwald, and Micah Lee
While The Intercept published this document, the accompanying articles focus on NSA's XKEYSCORE system broadly and does not analyze this specific document. The document appears only in the "Documents published with this article" sections without dedicated coverage. Academic searches, news archives, and general web searches reveal virtually no subsequent analysis or citation of this document. This pattern of important documents published but never publicly analyzed is unfortunately very common in the published Snowden documents.
