Researchers at the University of Leuven in Belgium and the University of Birmingham in the UK found a vulnerability in the encryption system used by car anti-theft controllers. Rather, the researchers found a vulnerability in the Texas Instrument encryption system DST80, which is implemented by Toyota, Hyundai and Kia.
Hackers use cheap Proxmark RFID transmitters to gather enough information near the Remote Key of the DST80 to infer its secret value, clone the remote key, and turn off the anti-theft system to start the car engine. Affected car models include the Toyota Camry, Corolla and RAV4; Kia Fars, Syol and Leo; and Hyundai I10, I20 and I40. Tesla’s Tesla S cars were also affected, and after the report, The researchers released a firmware update to fix the vulnerability.
