A hacker demonstrated how to intercept or take down all LTE phone calls and text messages.
The Register Explains:
Ruxcon Hacker Wanqiao Zhang of Chinese hacking house Qihoo 360 has blown holes in 4G LTE networks by detailing how to intercept and make calls, send text messages and even force phones offline.
The still-live attacks were demonstrated at the Ruxcon hacking confab in Melbourne this weekend, with the demo offering a recording of the hack perpetrated in part on a live network. It exploits fall-back mechanisms designed to ensure continuity of phone services in the event of overloads.
The tested Frequency Division Duplexing LTE network is more popular than TDD-LTE and operates in Britain, the US, and Australia. The competing Time Division Duplexing (TDD) LTE network is more common in Asian countries and in regions where population densities are higher.
