Priced at £257, the device lets criminals intercept the radio signal from the key as a car owner unlocks the vehicle. The receiver in your car contains an identically seeded pseudo-random number generator that yields the same sequence of random keys and knows the hard-coded identifier.Because of the possibility that a key fob may be "rolled" while out of range of the vehicle, the receiver pre-generates the next 256 possible keys and accepts any one of them. Lets take a look at a sample packet sent with Subaru RKEs:The preamble is the location of the identifier unique to each key and receiver combination. The total value of recovered vehicles was £13mMany new cars now have keyless entry systems, or can have them added as an upgrade. In this guide, we will take a look at a few exploits that target remote keyless entry (RKE) systems in modern vehicles. SMB attackers do not need to know a client’s password; they can simply hijack and relay these credentials to another server on the same network where the client has an account.The principal is similar in a network attack: Joe (the victim with the credentials the target server called Delilah needs before allowing anyone access) wants to log in to Delilah (who the attacker wishes illegally to break into), and Martin is the man-in-the-middle (the attacker) who intercepts the credentials he needs to log into the Delilah target server.In the below diagram from SANS Penetration Testing, the A contactless smart card is a credit card-sized credential.
