On September 1, the popular Brazilian television news magazine Fantástico reported about an NSA operation for wiretapping the communications of the presidents of Mexico and Brazil. Fantástico is part of the Globo network, which already disclosed various top secret NSA presentations last July.
Now, the Brazilian magazine showed some new top secret NSA documents, like a powerpoint presentation about the eavesdropping operation, which were all among the thousands of documents which Edward Snowden gave to Guardian journalist Glenn Greenwald in June.
Fantástico also published the slides on their website, but as that's only in portuguese, we show these slides too, because they give a nice graphical insight in how the NSA intercepts foreign communications.
Below the graph is the word SCIMITAR, seen here for the first time, which could be a tool to create such contact graphs, or maybe a database containing metadata from which these contacts can be derived.
1. Selectors, like known e-mail adresses or phone numbers related to EPN (Enrique Peña Nieto) are used as seeds to start the process.
2. The initial seeds lead to 2-hop graphs, apparently based upon metadata which are in the databases mentioned below the graph: MAINWAY is the NSA's database of bulk phone metadata, CIMBRI is seen here for the first time, and could be another kind of metadata database. JEMA probably stands for Joint Enterprise Modeling and Analytics, which is a tool that allows analysts to create more complex analytic scenarios.
3. Next, addresses discovered by creating the contact graphs can act as selectors for collecting SMS messages. For this the MAINWAY database is used too, just like ASSOCIATION, which, according to the Fantástico website, gathers information circulating on social networks.
4. Finally, these messages go to a filter named DISHFIRE, which searches them for certain keywords.
The next three slides show somewhat more about the specific elements of the process:
This presentation gives insight in a specific eavesdropping operation, but also gives a good idea of how NSA is collecting information from the internet in general, for example through PRISM and various other programs which gather data from internet backbone cables.
Allthough the presentation is clarifying, it could also have been published without mentioning the specific targets involved. Showing that this operation targeted the presidents of Mexico and Brazil did not serve a public interest, but unnecessarily damaged the relationship between the United States and both countries.
Glenn Greenwald seemed to justify the publication by saying that the presentation proved that NSA was also intercepting the content of phone calls and e-mail messages. After earlier disclosures, the US had said that they only collect bulk metadata from Brazil and no content. But of course this statement only applied to ordinary citizens, as eavesdropping on foreign political and military leaders is generally considered to be a legal activity of (signals) intelligence agencies.
Greenwald, who lives in Rio de Janeiro, also said that "most of the spying they [= the US] do does not have anything to do with national security, it is to obtain an unfair advantage over other nations in their industrial and commerce economic agreements". But with this motive he also acts more in the national interest of Brazil, or at least like an activist, than as a journalist working for the public interest.
