What are the ways to steal a car? How to protect your car from the digital methods of theft?
Read this out in our Friday’s talk with Author Alarm Senior Technician – Nikolay Kosarev.
Nikolay: Progress is relentless: today mainly digital methods of theft are relevant, so it is quite logical to protect them in a digital way.
We design our security devices taking into account many technical nuances of the theft methods, therefore our products are so reliable. We do our best to protect the car in the most natural way for it: at a modern and safe digital level.
To make it clear, let’s imagine that we are thieves, and our first task is to get into the car. Then there are several ways of disabling standard security system: for example, connecting to the car’s CAN-bus through the front wheel arch or the rear fender. Then we can open the central lock programmatically, switching off the standard security system at the same time. Or we can just disable the wiring of the standard horn & the alarm and then break the window or open the door lock mechanically. So …. we are inside the car and can act in several ways.
Way 1: key cloning.
There is no secret that the information about the keys is stored in the certification block. In order to register new keys, you just need to connect to the standard diagnostic port (OBD-II) and get the necessary data to steal the car.
What can we do against that?
Nikolay: we suggest a prohibition of a new key registering . Our digital anti-theft system IGLA has built-in protection against new keys registering. There is no chance to create a new key – and the car is safe.
Way 2: the so- called « key canceller».
Slang name immediately tells about the essence of the device: the « key canceller» was created in order to start, or turn on the engine without a key. You do not even need to register new ones – just connect the « key canceller» either to the standard diagnostic port or to the certification unit and here we go: the car is yours;)
What will be a solution for that ?
Nikolay: Our answer is digital blockings. IGLA requires PIN-code input with standard buttons. Without it, the system will digitally prohibit the engine start or switch it off when trying to start a movement.
Way 3: overriding of OE CAN-blockings.
Nikolay: Let me take Toyota as example: these cars can be started and driven even if the CAN-bus is damaged. Of course, there will be errors in the work of standard systems, loss of power and other inconveniences, but the car still will be able to ride. Thieves decided to take advantage of this feature and disable the CAN-bus using a simple paper clip.
How does it work?
A clip can be put into the diagnostic connector OBD-II – this will instantly cause a CAN short circuit, and the anti-theft device will not be able to send commands to block.
Checkmate situation, isn’t it?
Nikolay: Not exactly. Solution is additional blocking. For that we equipped our system with special additional relays (digital relay TOR and analog relay AR20) to block the engine even in case of CAN-bus short circuit. We also work both with CAN and LIN-buses, so, even if the CAN-bus is unavailable, the anti-theft system will prevent the engine from starting using the LIN-bus.
Any other scary ways of car theft?
Nikolay: ..yes.. There is also a way for the most sophisticated thieves, don’t underestimate them!
It’s the legendary «eye», which can grab the PIN-code. The thieves use the special device to be connected to the OBD-port, which is capable to collect all data from the driver’s car during the day and grab the PIN-code finally. You would ask, how can this be done? Easy: during car service someone can put the device into your car.
Sounds impressive, but in practice everything is not that easy, isn’t it?
Nicolay: Yes, the thieves must install the equipment in advance, wait until the «eye» collects data about the PIN-code, then re-enter the car. And that is even not all! Then you have to connect to the «eye» and analyze the recorded data – it will also take time. After that, you can try to use the received code, but it will work only if the real PIN-code was indeed recognized completely and without errors. After all, in addition to information about the PIN-code, a huge amount of other data passes through the bus, and it is impossible to guarantee one hundred percent result but this way exists and cars are still being stolen.
What would be a solution for the «eye» then?
Nicolay: we considered this way of theft and added IGLA with two-factor authorization. In this case, IGLA can be disarmed only when you authorize yourself using both key-fob/smartphone and PIN.
Voilà, the problem is solved and the goal is achieved: the thieves are left in the dust and the car is reliably protected.
Be careful and do not leave your authorization tools unattended – we will take care of the rest!
