Just when you thought you were safe, a new hacking toy comes along and rocks your world. Imagine a tool exists that lets hackers pluck encryption keys from your laptop right out of the air. You can’t stop it by connecting to protected Wi-Fi networks or even disabling Wi-Fi completely. Turning off Bluetooth also won’t help you protect yourself.
Why? Because the tiny device that can easily be hidden in an object or taped to the underside of a table doesn’t use conventional communications to pull off capers. Instead it reads radio waves emitted by your computer’s processor, and there’s really nothing you can do to stop it.
