Whistleblower & Exiled Snowden, together with hacker Andrew “Bunnie” Huang, has designed a case-like attachment to modify an iPhone, where you can monitor radio transmitters within the device. Huang is known among other things for reverse engineering parts of the original Xbox and security vulnerabilities in microSD cards.
Snowden’s said a device such as this is needed because turning off the radios via airplane mode, shutting off the phone entirely, or even sealing it within a Faraday cage are all not nearly secure enough when faced with a government-backed adversary. Snowden and Huang’s device offers an option for reporters and journalists traveling in areas that use high-level hacking methods to monitor devices, and where, they claim, governments can use exploits to trick you into thinking your phone is off while actually monitoring your conversations and locations. Snowden and Huang hope that their device will offer security to reporters in high-risk locations by preventing the monitoring or tracking of phones. The device is still in testing stages.
