F: car hacking

Hey 'n welcome. Today we're going to talk about car hacking..
Before we talk about what we can do, lets talk about what we cant do.
Its tricky to know what is possible and not until you learn how the key radio frequent works.

Already in the late 80's mostly of the wireless car key systems used techniques like TKIP,
It was made for preventing the same 'key' used twice. So every time you click on your car key knob you are getting a different key every time.
But the key knob most be in range of the car to register the 'key' as used. So if you record the frequent that has been transmitted
out of range, than you can use it anytime you want and unlock the car(1 time ofc).

So witch that in knowledge, we know now that we cant get access to a car without the key, it's simple impossible to bruteforce it..

There's some different techniques that we can use to unlock a car though..
As described earlier we can

Save the transmitted key signal when the signal is out of range of the car.
Or we can jam the signal and save all of the lock/unlocking signals,
(you can often modify the signal and turn a locking signal into a unlock signal)


Hope that I've cleared the basics with you know, this topic is very misunderstood and we ain't living in Hollywoods movies.


Last words:
For transmitting and receiving radio frequents you haft to get a SDR(software defined radio)
One good full duplex SDR is 'Blade rf' and half duplex 'Hackrf'
i would go with the Blade rf.
