![]() Researchers from KU Leuven in Belgium and the University of Birmingham in the UK earlier this week revealed new vulnerabilities they found in the encryption systems used by immobilizers, the radio-enabled devices inside of cars that communicate at close range with a key fob to unlock the car's ignition and allow it to start. ![]() A few cryptographic flaws combined with a little old-fashioned hot-wiring-or even a well-placed screwdriver-lets hackers clone those keys and drive away in seconds. Now it turns out that many millions of other cars that use chip-enabled mechanical keys are also vulnerable to high-tech theft. ![]() Over the past few years, owners of cars with keyless start systems have learned to worry about so-called relay attacks, in which hackers exploit radio-enabled keys to steal vehicles without leaving a trace.
