This unprotected period lasts 130 seconds – the same time a Tesla driver can start their car with their NFC card after unlocking the vehicle.

Australian security researcher Martin Herfert found that Tesla exchanged messages with any nearby Bluetooth Low Energy device, Ars Technica Report.

Herfurt created an app called TeslaKey that speaks VCSec, which is what Tesla’s app uses to communicate with its vehicles.

The only requirement for a successful infraction is to be within range of the car.

Drivers who unlock their car with Tesla’s phone-as-a-key app are at similar risk.

Hackers can use signal jammers to block the BLE frequency emitted by Tesla’s phone-as-a-key app and force it to use a driver’s NFC card.

Thieves with Tesla digital keys can unlock, start and stop the car, Ars Technica Report.

Herfurt has successfully hacked Tesla’s Model Y and Model X.

While Herfurt hasn’t tested his finding on Tesla’s 2021+ Model S and Model X—he estimates these vehicles are at risk because they use the same phone-as-a-key support system.

Tesla did not respond to an email seeking comment on the matter, wired Report.

According to Wired, Herbert uncovered additional Tesla vulnerabilities in 2019 and 2021, only to experience more radio silence from the electric maker.
