If you have a car Volkswagen, maybe it can open without keys, that is, can be hacked Two security vulnerabilities discovered by a computer scientist demonstrate how millions of cars can be started without keys in addition to the doors.
Specifically, already in 2013 a group of researchers from the University of Birmingham discovered how to start Volkswagen cars by hacking, but they were sued.
Now they have made public that security flaw along with another that allows to open the doors of a large number of cars. In addition, they point out that it affects millions of Volkswagen cars sold since 1995.
In the Usenix security conference held this week they have published all the details about these two security flaws. And it is that we are not only left with Volkswagen but also includes models from Audi and Skoda, which are from the same group. But also to the competition, in some models of Alfa Romeo, Citroën, Fiat, Ford, Mitsubishi, Opel and Peugeot the failure that allows the doors to be opened has been found without key.

How to Hack Cars
Experts have explained that to hack cars all you need is an Arduino board with a radio receiver, which involves a cost $40.
In short, it is necessary to intercept the signal and then we will take control as if we had the key ring.
Now we will have to see if Volkswagen can solve this problem that affects millions of cars. Otherwise, we could soon see how cars are stolen by exploiting vulnerability.
