the Vulnerability affects almost all the Volkswagen cars manufactured since 1995.

Three years ago a team of researchers led by scientists at the University of Birmingham (UK) Flavio Garcia (Flavio Garcia) have discovered a vulnerability in Volkswagen cars allows you to start and drive the car without the key. Instead of gratitude, the experts received the lawsuit, which the publication of details about the discovery was postponed for two years. However, the difficulties did not stop Garcia and his colleagues, and a year after disclosure of the vulnerability the researchers found two more.

According to Garcia and German experts of the company Kasper & Oswald, the vulnerabilities affect not only the ignition system, but the system of automatic opening of doors. The problem affects virtually all Volkswagen cars manufactured since 1995 (about 100 million vehicles).

One of the detected attack allows an attacker with the appropriate equipment to open air almost any Volkswagen released in the past two decades, including the brands Audi and Škoda. The second method involves more and more machines, including the brand Alfa Romeo, Citroen, Fiat, Ford, Mitsubishi, Nissan, Opel and Peugeot.

For the implementation of both attacks with just a cheap radio that easily can be purchased or assembled at home. With it, an attacker capable of intercepting the signal transmitted with the key of the owner of the car, and clone the key. An attacker can use a laptop with appropriate software or an Arduino Board with a radio (cheaper and more convenient way). "You can pick the device that works exactly the same as the original remote control," - said Garcia.

Attack on Volkswagen cars causes great concern as to its implementation with one push on the button, and the driver will remain ignorant, because the system cannot provide warnings in case of a break-in.

Through reverse engineering of one of the components of the internal network of the Volkswagen, the researchers were able to get the value of a single encryption key used in millions of cars. Then use the radio equipment they intercepted another meaning that is unique to your vehicle and transferred each time the driver presses the button of the key FOB. Having both values, the researchers cloned the key and gained access to the vehicle.
