Most hacking attacks are not so easy to carry out. We all know that various functions of a moving car can be hijacked. All it takes is a hacker with local or remote access. Security researchers at the University of Birmingham discovered attack methods focusing on vulnerabilities in remote key-less entry systems (RKE). RKE systems use cryptography and a counter value to generate a rolling code signal. The vehicle then decrypts the signal and verifies to ensure that it is a new counter value to prevent replay attacks. According to the team of researchers, attackers could intercept the signal from up to 100 meters. Then they create a clone of the original remote control by decryption of information.
