The israeli private intelligence company Rayzone Group appears to have had access to the global telecommunications network via a mobile operator in the Channel Islands in the first half of 2018, potentially enabling its clients at that time to track the locations of mobile phones across the world.
Invoices seen by the Guardian and the Bureau of Investigative Journalism suggest Rayzone, a corporate spy agency that provides its government clients with “geolocation tools”, used an intermediary in 2018 to lease an access point into the telecoms network via Sure Guernsey, a mobile operator in the Channel Islands.
Such access points, known in the telecoms industry as “global titles”, provide a route into a decades-old global messaging system known as SS7, which allows mobile operators to connect users around the world. It is not uncommon for mobile companies to lease out such access.
