Keyless car owners had to quickly learn about new hacking techniques where a hacker used the radio waves to start the car. Now, vehicles with a chip and a mechanical key are being found to have a weakness. Toyota, Hyundai, and Kia vehicles have been found to especially be at risk, with hackers replicating the feature that unlocks the vehicle when your key fob is nearby. Tesla had originally been found to be affected as well, but quickly released a firmware update that resolved the issue. Toyota has confirmed the vulnerability of the listed vehicles, and more are being researched for the same flaw. Once the hacker has unlocked the car’s engine, they simply need to use a screwdriver to start the ignition or pull off an old-fashioned hot wire.
