You've heard about cyberstalking. Creeps hack into your smartphone and listen in on your calls, read your text messages, and use GPS to track your physical location.

It's a terrifying thought, but "60 Minutes" proved this week that hackers can do that in just a few seconds. They demonstrated on Congressman Ted Lieu's phone (he gave them permission).

They were exploiting a worldwide security hole that affects millions of smartphone users like you. It centers on something called the Signalling System No. 7, or SS7.

It's the system, or protocol used to connect 800 cellphone providers around the world. So, for instance, if you're a Verizon customer calling a Deutsche Telekom customer in Europe, you're being connected through SS7.

The problem is, no one really knows how good the security is for all those 800 companies. As the site Ars Technica recently wrote, "The problem with SS7 is that it's only as secure as its least secure or trustworthy member."
