Researchers Find Super Simple Way to Hack Tesla Keys

Security researchers have found numerous vulnerabilities in some of today’s most popular vehicles, including finding ways to access owner data, take control of vehicle systems, and more. Tesla’s vehicles aren’t immune, and a team of researchers recently showed how easy accessing one of the advanced EVs with a simple electronic device can be.


The crew at Mysk has found a way to clone Tesla owners’ keys by hacking into the wireless internet networks at the automaker’s Supercharger stations. They use a device called Flipper Zero, which can broadcast a fake Wi-Fi network with a name similar to the ones used at Superchargers.


Once the user is connected and has entered their Tesla account information, their data is captured by the Flipper Zero. Hackers then prompt the user for a multi-factor authentication code, which allows them to access a Tesla account using an app on their smartphones. The hackers can then gain access to the car, clone a key using the Flipper Zero, and other malicious actions.


Some companies pay bounties to hackers who come forward with information about a vulnerability or security issue, but Tesla’s response to Mysk was surprising. The automaker responded, “Thanks for the report. We have investigated and determined that this is the intended behavior. The ‘Phone Key’ section of the owner’s manual makes no mention of a key card being required to add a phone key.”


While there are a few steps involved in this hack, and the bad actors have to be somewhat nearby to commit the crime, it’s worth noting that this is one of the simpler vulnerabilities we’ve seen so far. Some hackers have outlined having to access deeply protected vendor accounts and other complicated pathways to gain user info, while this one appears to be pretty straightforward by comparison.

    This is called a man in the middle attack and has been around for years. You can fall for this in a Starbucks as easily as when you’re charging your car. Nothing new here…

  • Kwik_Shift_Pro4X As much problems as I had with my '96 Chevy Impala SS.....I would love to try one again. I've seen a Dark Cherry Metallic one today and it looked great.
  • Susan O’Neil There is a good reason to keep the Chevrolet Malibu and other 4 door family sedans! You can transport your parents and other somewhat handicapped people comfortably and safety! If someone can stand and pivot you can put them in your car. An armrest in the back seat is appreciated and a handle above the door! Oh…and leather seats so your passenger can slide across the seat! 😊Plus, you can place a full sized wheelchair or walker in the trunk! The car sits a little lower…so it’s doable! I currently have a Ford Fusion and we have a Honda Accord. Our previous cars were Mercury Sables-excellent for transporting handicapped people and equipment! As the population ages-sedans are a very practical choice! POV from a retired handicapped advocate and daughter! 😊
  • Freddie Remember those ads that say "Call your doctor if you still have...after four hours"?You don't need to call your doctor, just get behind the wheel of a CUV. In fact, just look at one.I'm a car guy with finite resources; I can't afford a practical car during the week plus a fun car on the weekend. My solution is my Honda Civic Si 4 door sedan. Maybe yours is a Dodge Charger (a lot of new Chargers are still on dealer lots).
  • Daniel J Interesting in that we have several weeks where the temperature stays below 45 but all weather tires can't be found in a shop anywhere. I guess all seasons are "good enough".
  • Steve Biro For all the talk about sedans vs CUVs and SUVs, I simply can’t bring myself to buy any modern vehicle. And I know it’s only going to get worse.
