> At some point you have to wonder how privacy and security wasnt a factor at all in the minds of engineers designing these systems- it has to be intentional, right? Yes. SS7 is a half-century old, designed for a world of state telecom monopolies and a handful of tightly-peered carriers. The threat model could safely assume that only vetted operators could connect. It's unlikely that anyone involved believed that SS7 would still exist in 2000, much less 2025. https://www.eff.org/deeplinks/2024/07/eff-fcc-ss7-vulnerable... |
