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…

  • Peter Buying an EV from Toyota is like buying a Bible from Donald Trump. Don’t be surprised if some very important parts are left out.
  • Sheila I have a 2016 Kia Sorento that just threw a rod out of the engine case. Filed a claim for new engine and was denied…..due to a loop hole that was included in the Class Action Engine Settlement so Hyundai and Kia would be able to deny a large percentage of cars with prematurely failed engines. It’s called the KSDS Improvement Campaign. Ever hear of such a thing? It’s not even a Recall, although they know these engines are very dangerous. As unknowing consumers load themselves and kids in them everyday. Are their any new Class Action Lawsuits that anyone knows of?
  • Alan Well, it will take 30 years to fix Nissan up after the Renault Alliance reduced Nissan to a paltry mess.I think Nissan will eventually improve.
  • Alan This will be overpriced for what it offers.I think the "Western" auto manufacturers rip off the consumer with the Thai and Chinese made vehicles.A Chinese made Model 3 in Australia is over $70k AUD(for 1995 $45k USD) which is far more expensive than a similar Chinesium EV of equal or better quality and loaded with goodies.Chinese pickups are $20k to $30k cheaper than Thai built pickups from Ford and the Japanese brands. Who's ripping who off?
  • Alan Years ago Jack Baruth held a "competition" for a piece from the B&B on the oddest pickup story (or something like that). I think 5 people were awarded the prizes.I never received mine, something about being in Australia. If TTAC is global how do you offer prizes to those overseas or are we omitted on the sly from competing?In the end I lost significant respect for Baruth.
