Keyless entry technology has been released by the biggest car companies. For some of you that do not know what is it. Let me explain. The main purpose of this brilliant piece of tech is to allow car owner to get into it without any interaction besides pulling the handle. It is possible thanks to keys and cars using the same algorithms where the key sends a signal to your car which has to be the matching.
I will concentrate on one of the most dangerous, time and cost effective type of attack which is not well known in Poland.
Replay attack
The best method if you want to steal your neighbour’s ride. Its simplicity is almost unbelievable.
In order to perform that type of attack you only need a 20$ arduino board and a piece of code which is available online on github for free. I will not link it in this blog post, because I do not want to be responsible of you commiting a car theft later.
How it might look in practice?
The first step is to leave the arduino board somewhere under the car with the programme turned on which is looking for a key signal. When the owner of a car unlocks it, it will record the original signal and send it to the attacker. The second and also the last step of perfoming this attack is to come near the car with mobile device which can emmit a signal in order to repeat the original signal which was sent to us earlier. Then attacker can casually get into the car, start it and drive towards the setting sun.
I found a video which shows that kind of illegal practice, of course in educational purposes. I will link it down below if this topic caught your attention and you want to know more about it in order to be informed and know how to protect yourself against common car theft methods.
What do you think about technology which is create to make our lives easier and more enjoyable, but at the same time creates an opportunity which someone might use against us.
Do you think there are more examples of that kind of tech ? I strongly encourage you to discuss about that in the comment section down below.
