wired: The aim of that add-on, Huang and Snowden say, is to offer a constant check on whether your phone’s radios are transmitting. by Andy Greenberg
'They say it’s an infinitely more trustworthy method of knowing your phone’s radios are off than “airplane mode,” which people have shown can be hacked and spoofed. Snowden and Huang are hoping to offer strong privacy guarantees to smartphone owners who need to shield their phones from government-funded adversaries with advanced hacking and surveillance capabilities—particularly reporters trying to carry their devices into hostile foreign countries without constantly revealing their locations.
'“One good journalist in the right place at the right time can change history,” Snowden told the MIT Media Lab crowd via video stream. “This makes them a target, and increasingly tools of their trade are being used against them.”
'“They’re overseas, in Syria or Iraq, and those [governments] have exploits that cause their phones to do things they don’t expect them to do,” Huang elaborated to WIRED in an interview ahead of the MIT presentation. “You can think your phone’s radios are off, and not telling your location to anyone, but actually still be at risk.”'
