Phone network security flaw lets anyone bug your calls
Mobile phone users are at risk from a signalling flaw that allows hackers to intercept all voice calls and track locations.
Australian TV programme 60 minutes is claiming the scoop, showing in a special report how hackers were able to record the mobile phone conversations of a prominent politician and track his movements from a base thousands of miles away in Germany.
This is because of a flaw in the architecture of the signalling system, known as SS7, which is used to enable mobile phone roaming across telecoms providers, according to the programme. A hacker can use this information to listen in to any mobile phone conversation by forwarding all calls to an online recording device and then re-routing the call back to its intended recipient, a so-called man-in-the-middle attack.
