Why SS7 remains a dangerous fallback

A developer at an AI startup wanted to cheat at Roblox. They downloaded a dodgy script on their work laptop. That one decision triggered a cascade of failures that ended with a $2 million data breach affecting hundreds of thousands of organisations. All for some free in-game currency.

Meanwhile, there's a 1980s phone protocol called SS7 that lets shadowy surveillance companies track anyone, anywhere, via their mobile phone. Governments know about it. Telecoms know about it. Nobody's fixing it.

All this and more in episode 465 of the "Smashing Security" podcast with cybersecurity keynote speaker and industry veteran Graham Cluley, joined this week by special guest James Ball.

Plus! Don't miss our featured interview with Rob Edmondson of CoreView, discussing how to lock down Microsoft 365 before it's too late.
