Tesla hackers find a vulnerability with NFC relay attack

Tesla hackers have found a vulnerability with an NFC relay hack but there’s a catch. Thieves will have to work in pairs and get close to the NFC chip or smartphone.

According to IOActive, the relay attack needs two attackers. One uses the Proxmark device at the vehicle’s NFC reader. The other uses any NFC-capable device close to a Tesla owner’s NFC card or smartphone. The team is then able to use Bluetooth to communicate between the devices and replicate the key to one of the thieve’s smartphones.

This new demonstration comes a few days after the National Highway Traffic Safety Administration (NHTSA) recently released an update to its 2016 edition of its Cybersecurity Best Practices for the Safety of Modern Vehicles. Dr. Steven Cliff, NHTSA’s Administrator emphasized the need for cybersecurity to be a top priority for every automaker, developer, and operator.

According to the agency, a layered approach to vehicle cybersecurity reduces the probability of a successful attack while mitigating the ramifications of unauthorized vehicle system access. The NHTSA also added that public key cryptography techniques are more secure than symmetric keys valid across multiple vehicles.

In 2018, Tesla began rolling out the PIN to Drive feature and improved cryptography for its key fobs as a response to several Tesla vehicle thefts through relay attacks in Europe.

In 2019, Tesla began releasing over-the-air software updates addressing the findings of Lennert Wouters of Katholieke Universiteit Leuven in Belgium (KU Leuven). Wouters discovered a security flaw that allowed car thieves to clone a key fob in less than two seconds. Tesla’s solution included the PIN to Drive, a software update, and a new fob that made the Tesla Models S and X  almost 90% less likely to get stolen than the average car.

The new demonstration may show a vulnerability if thieves are dedicated enough to work at it, but Tesla is pretty fast at addressing these flaws. However, all car owners, whether they own an EV or not, should always be aware of their surroundings. You can watch IOActive’s demonstration video below.

Tesla’s Supercharger Diner probably just secured more locations

Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.

The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.

Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.

Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.

Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.

Tesla short sellers win big after shares fall after earnings

Tesla short sellers won big following the company’s massive fall on Wall Street after it reported subpar Earnings on Wednesday.

Tesla short sellers collected about $4.12 billion in single-day profits on Thursday, according to BloombergShares fell as much as 15 percent during Thursday’s session. It closed as one of the worst days for Tesla on Wall Street in the past three years.

Investors sold off the stock after Tesla said it would aggressively direct its spending toward AI and its Optimus robot project. The company had record revenues, which were driven by one of the strongest quarters in terms of vehicle deliveries in company history.

However, it missed EPS estimates by reporting just $0.33, a far cry from the $0.53 analysts expected.

S3 Partners reported that about 3 percent of Tesla’s outstanding stock is sold short. Managing Director at S3, Ihor Dusaniwsky, provided the short seller’s potential profit, as well as another figure: shorts have likely had paper gains of $8.92 billion this year, as Tesla shares are down 30 percent in 2026.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Tesla has burned short sellers many times in the past, but the company’s latest Earnings Call was a chance for those skeptics to taste some payback. Although the company gave some very transparent information regarding future projects, the rollout of Robotaxi, Optimus, and Semi, many investors took their profits on Thursday.

Notable short sellers like Michael Burry have been transparent about their skepticism around Tesla shares. Burry just revealed three weeks ago that he had opened up a new short on the stock, stating he shorted Tesla shares at $416.22. “Happy it jumped back to this level,” he said in a blog post.

Tesla door handle saga gets its latest chapter and a big change is coming

Tesla’s long-standing saga regarding its door handles and a manual release has entered its latest chapter, and as a result, a big change is coming.

On Friday, the National Highway Traffic Safety Administration (NHTSA) denied Tesla’s petition that was seeking a defect investigation into roughly 180,000 Model 3 vehicles for an issue involving the emergency mechanical door release.

NHTSA said that Tesla’s petition did not present evidence of a safety-related defect in the door handles or their emergency releases. Instead, the agency determined that it would rather solve the issue of the lack of labeling or location of emergency mechanical door releases and the federal safety rules that govern them.

Essentially, the NHTSA wants to create and enforce rules that would require automakers to make emergency door latch releases more clearly labeled in a car. Despite a Tesla having manual door releases on all four passenger doors, many people do not know they exist or how they work.

Tesla addresses door handle complaints with simple engineering fix

In recent times, Tesla has faced some criticism involving its door handles, specifically because some occupants have reported that they are unable to exit their vehicles after losing power. The door handles on a Tesla are electronically operated, but in the event that the 12V battery dies, there is a manual release that can be used.

The NHTSA only identified a single complaint involving the mechanical door releases: a 2022 Model 3 owner said the release was concealed and unlabeled after the vehicle lost power after a front-end collision. It has also already started to create a separate rulemaking process to make emergency door-egress systems more obvious.

It should be noted that all Teslas have mechanical emergency door releases, but they are placed in various locations as the vehicles have aged and been redesigned from year to year. Refer to the safety manual for your vehicle if you have any confusion about where the emergency releases are and how they work.
