NFC Relay Attack On Tesla Model Y
This paper will walk you through the proof-of-concept and technical
details of exploitation for IOActive's recent NFC relay attack on
the newest Tesla vehicle, the Model Y. To successfully carry out
the attack, IOActive reverse-engineered the NFC protocol Tesla uses
between the NFC card and the vehicle, and they then created custom
firmware modifications that allowed a Proxmark RDV4.0 device to
relay NFC communications over Bluetooth/Wi-Fi using the Proxmark's
BlueShark module.
