Edward Snowden designed an iPhone case to prevent wireless snooping: Edward Snowden is still trying to combat smartphone radio surveillance three years after spilling the NSA's secrets. With help from hacker Andrew "Bunnie" Huang, Snowden presented on Thursday designs at the MIT Media Lab for a case-like add-on device that monitors electrical signals sent to an iPhone's internal antennas.
It looks like an external battery case with a small mono-color screen and is being described as an "introspection engine." The device's tiny probe wires have to attach to test points on the iPhone's circuit board, which are accessible through the SIM card slot. The phone has two antennas that give off electrical signals and they're used by its radios, including GPS and Bluetooth.
