A feature that Tesla, Inc. announced in 2021 to make life easier for its car owners has provided a loophole for hackers to barge in.
What Happened
Hackers can exploit a feature that lets Tesla owners create their own key to open their cars, Martin Herfurt, an Austrian security researcher found, as per an Ars Technica report.How It Works
The update makes it easier to start a Tesla vehicle via near-field communication (NFC) key card. It triggers the EV to automatically start within 130 seconds of unlocking with the NFC card.While allowing this, the feature also puts the car in a state of accepting entirely new keys without requiring authentication, the researcher said. Indication about this is not given by the in-car display either, he said.
