Mobile security is obviously a major topic these days but it seems very few of us know just how vulnerable our phones are to hacking. 60 Minutes this week decided to give a new iPhone to Representative Ted Lieu (D-Calif.) and then challenge researchers at Security Research Labs to hack it. It goes without saying that the hackers were frighteningly successful in this endeavor and managed to retrieve a lot of sensitive information from the congressman’s device after only learning his phone number.

Seriously, that’s all it took: As soon as they had the device’s phone number, they were able to listen to and record all his phone calls, to read his text messages and to track his location.

The problem here isn’t with Apple’s security policies but the way that mobile networks around the world connect to one another. The team at Security Research Labs have discovered a major flaw in Signaling System 7 (SS7), a series of protocols first developed way back in 1975 to connect phone carriers around the world. This is a vulnerability that literally affects every single person who owns a cellphone, which is why we should hope that knowledge of this flaw with SS7 is not yet widespread.

That said, 60 Minutes also points out that most hackers don’t go through SS7 to hack your device — the program interviews Lookout Security cofounder John Hering, who details some of the other ways that hackers can get access to your phone.
