funtenna: sound wave hacking technique.
A new hacking technique that uses sound and radio waves can siphon data from devices even without internet access. Showcased at the Black Hat security summit in Las Vegas, the ‘Funtenna’ hack has the potential to unravel the Internet of Things.
By uploading a malicious program to a device, the hackers can vibrate the physical prongs on general-purpose input/output circuits at a frequency of their choice. The resulting vibrations can be picked up by an AM radio antenna.
The setup, dubbed “Funtenna” by its creators, was presented to the audience at the Black Hat hacking conference in Las Vegas on Wednesday by Ang Cui of the Manhattan-based Red Balloon Security.
Cui, who recently completed a PhD at Columbia University, spoke with several reporters before his presentation, providing a preview of the technique. Unlike the previous hacking techniques, “Funtenna” works by turning the infected device into a transmitter.
