SS7 is the global telecommunications backbone network. You use it every time you make a call, receive a text message or use the mobile network's internet access. But to be reachable, the network has to know your location. And access to the SS7 network is getting easier and easier, without the security measures keeping up.
As a follow-up to 25C3's "Locating Mobile Phones using SS7" this talk will offer a look at what has changed in the last six years. I will show how easy it is for intelligence services and criminals to circumvent the network's defenses to get the data they want, just based on your phone number.
