The Silly World of Cybersecurity

For Petty Laws, Let’s just ban antennas!

Yesterday, five cars were stolen in my local area. These were high-end vehicles, and it is likely that they involved keyless entry. In fact, most of the cars that are stolen these days involve keyless entry, and where the days of feeding a coat hanger down your window are gone. The days, too, of a piece of metal in a slot protecting our vehicles are also gone. Most people like the convenience of using key fobs, and most would like a vehicle that they do not even need to take the key fobs out of their pockets. We now live in a world where we like automation and we love our “tech”.

For keyless carjacking, the key continually transmits a beacon, and the car will only sense the key when the signal strength is strong enough. To open the car, a person then stands near to where the keys are, and then broadcasts this signal to someone waiting near the car:

The recorded signal can then be stored, and played back for future use to start the car. What’s the problem here? Well, car owners should be shielding their keys when they are at home, such as putting them in a metal container or at least placing them away…
