"Hackers Can Clone Millions of Toyota, Hyundai, and Kia Keys"

Researchers from KU Leuven in Belgium and the University of Birmingham in the UK recently revealed new vulnerabilities that they discovered in the encryption systems used by car engine immobilizers, the radio-enabled devices that allow the ignition to be unlocked and started by receiving signals from a key fob near the devices. A hacker could use a Proxmark RFID reader/transmitter device near the key fob of any car that implements a Texas Instruments encryption system, called DST80, to gather information and obtain its secret cryptographic value. This cryptographic value could then be used by hackers to impersonate the key inside the car, deactivate the immobilizer, and start the engine. According to researchers, these vulnerabilities affect the Toyota Camry, Corolla, Hyundai 110, and other car models with DST80 inside. This article continues to discuss the cryptographic weaknesses found by the researchers, the attacks developed to demonstrate the exploitation of these vulnerabilities, and how affected carmakers have responded to this discovery.
