According to a new report by Der Spiegel, the British signals intelligence spy agency has again employed a “quantum insert” technique as a way to target employees (Google Translate) of two companies that are GRX (Global Roaming Exchange) providers.
The lead author of the story in the German magazine is Laura Poitras, one of the journalists known to have access to the entire trove of documents leaked by former National Security Agency contractor Edward Snowden.
GRX is roughly analogous to an IX (Internet Exchange), and it acts as a major exchange for mobile Internet traffic while users roam around the globe. There are only around two dozen such GRX providers globally. This new attack specifically targeted administrators and engineers of Comfone and Mach (which was acquired over the summer by Syniverse), two GRX providers.
