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…

  • Jeff Overall I prefer the 59 GM cars to the 58s because of less chrome but I have a new appreciation of the 58 Cadillac Eldorados after reading this series. I use to not like the 58 Eldorados but I now don't mind them. Overall I prefer the 55-57s GMs over most of the 58-60s GMs. For the most part I like the 61 GMs. Chryslers I like the 57 and 58s. Fords I liked the 55 thru 57s but the 58s and 59s not as much with the exception of Mercury which I for the most part like all those. As the 60s progressed the tail fins started to go away and the amount of chrome was reduced. More understated.
  • Theflyersfan Nissan could have the best auto lineup of any carmaker (they don't), but until they improve one major issue, the best cars out there won't matter. That is the dealership experience. Year after year in multiple customer service surveys from groups like JD Power and CR, Nissan frequency scrapes the bottom. Personally, I really like the never seen new Z, but after having several truly awful Nissan dealer experiences, my shadow will never darken a Nissan showroom. I'm painting with broad strokes here, but maybe it is so ingrained in their culture to try to take advantage of people who might not be savvy enough in the buying experience that they by default treat everyone like idiots and saps. All of this has to be frustrating to Nissan HQ as they are improving their lineup but their dealers drag them down.
  • SPPPP I am actually a pretty big Alfa fan ... and that is why I hate this car.
  • SCE to AUX They're spending billions on this venture, so I hope so.Investing during a lull in the EV market seems like a smart move - "buy low, sell high" and all that.Key for Honda will be achieving high efficiency in its EVs, something not everybody can do.
  • ChristianWimmer It might be overpriced for most, but probably not for the affluent city-dwellers who these are targeted at - we have tons of them in Munich where I live so I “get it”. I just think these look so terribly cheap and weird from a design POV.
