There's something you need to know, hackers are everywhere and they want your stuff. Hackers are not just ready to take your computer, now they are also ready to take your car. There's a way to prevent that: wrapping your car keys in aluminum foil to help prevent hackers from breaking in and taking your car.
The hack is commonly known as the relay hack and it allows two radios near by to communicate with both the car's key and the car. This will allow the hackers to then unlock the car and start the vehicle all while the owner has no idea. More info here
