FLYING PIG: GCHQ's TLS/SSL knowledge base

December 17, 2013

Documents from the ICTR-NE (Information and Communications Technology Research - Network Exploitation) organization at the GCHQ show that it operates a program under the name FLYING PIG that provides analysts with information about secure communications over TLS/SSL. The primary motivation for this program was the increasing use of TLS/SSL by GCHQ targets, according to one of the documents.

The documents, originally published by Brazilian TV program Fant√°stico in September, provide an insightful look into the program that allows analysts to query the vast repository of metadata about the world's secure communications. In this article, I describe the program on the basis of some actual screen captures of its interface.

No, the NSA was not behind the DigiNotar hack

September 14, 2013

On Tuesday I found that former Dutch certificate authority DigiNotar, known for its security breach in 2011, was briefly mentioned in a Globo video report about NSA spying on Sunday. I documented the finding in a few tweets and put the four frames (of the same slide) that mentioned the name DigiNotar together in an album. Because the slide was only partly visible I had a difficult time making any sense of it. So, I wrote down what I considered to be plausible:

From the part of the text that is visible I suspect at least NSA's 'Flying Pig' was used in some investigation of the security breach.

What an e-book watermark looks like

September 07, 2013

In recent weeks, there was some fuss about a new agreement between digital book distribution platform eBoekhuis and connected vendors. This agreement obliges vendors to hand over previously-private customer information to anti-piracy group BREIN, should a purchased e-book at some point turn up on the internet (e.g. BitTorrent, Usenet, file-sharing sites). In order to trace a book back to the customer, a transaction code is watermarked into it. When I noticed one of the eBookhuis-connected vendors (i.e. started selling watermarked e-books, I bought one to see what this watermark would look like.
