So many questions! Does this still work? On any phone using SS7? Including landlines and mobile phones? From anywhere in the world? To anywhere in the world? What are the limitations of the attack? Why isn't this a vastly bigger problem if anyone can listen in on anyone's calls?

- cbsmith 2y agoYeah, SS7 was not really designed for the scenarios it now finds itself in (hell, I remember my dad talking to me about it back in the 80's). It's amazing how well it works, but that's exactly the context where one expects to find security vulnerabilities in spades. https://en.wikipedia.org/wiki/Signalling_System_No._7 https://en.wikipedia.org/wiki/Signalling_System_No._7
