Acoustic Attack Against Accelerometers (Schneier on Security)

2017-04-04 11:23

Interesting acoustic attack against the MEMS accelerometers in devices like FitBits. Millions of accelerometers reside inside smartphones, automobiles, medical devices, anti-theft devices, drones, IoT devices, and many other industrial and consumer applications. Our work investigates how analog acoustic injection attacks can damage the digital integrity of the capacitive MEMS accelerometer. Spoofing such sensors with intentional acoustic interference enables an out-of-spec...
