Millions of Smartphones Could Be Vulnerable to Hacking via Sound Waves

‘Scientists have found a new vulnerability in a common tech component, uncovering a security flaw that could expose potentially millions of smartphones, fitness wearables, and even cars to hacking.
By using sound waves, researchers have figured out how to trick accelerometers – the tiny sensors in gadgets that detect movement – into registering a fake motion signal, which hackers could exploit to take control of our devices.
