"Signalling System 7, or SS7, is a decades-old set of protocols that allows phone networks to communicate with one another, routing messages and calls across borders. It was never designed with security in mind, and while operators have moved to more secure evolutions with 4G and 5G, they still need to maintain backwards compatibility with SS7. This is likely to remain the case for years if not decades to come. Phone networks need to know where users are in order to route text messages and phone calls. Operators exchange signalling messages to request, and respond with, user location information. The existence of these signalling messages is not in itself a vulnerability. The issue is rather that networks process commands, such as location requests, from other networks, without being able to verify who is actually sending them and for what purpose. These signalling messages are never seen on a user’s phone. They are sent and received by “Global Titles” (GTs), phone numbers that represent nodes in a network but are not assigned to subscribers. Surveillance companies have often leased GTs from phone operators and used them to send unauthorised signalling messages into other networks, benefitting from the fact that the signalling messages appear to be coming from the legitimate operator which owns the GT. First Wap primarily works via in-country installations of Altamides. In this setup, a government client uses Altamides via an SS7 link belonging to a local phone operator. The local phone operator provides the GTs and Altamides uses these GTs to conduct location tracking domestically and internationally." So basically the telecoms network itself has no security. Anyone operating network equipment on the telecoms network can see where any phone is at any time. I didn't know we lived in a world that is this stupid. Great. If you're a dissident you basically cannot have a phone or be around anyone who has a phone.
