Details Behind the Tesla Model S Hack
Two researchers broke into the software of a Tesla recently. But there is good news behind the Tesla Model S hack. A fix was sent to all cars within days.

Last week, Marc Rogers, of content delivery network CloudFlare, and Lookout Mobile Security co-founder Kevin Mahaffey completed a digital break-in of a Tesla. But here’s the good news behind the Tesla Model S hack. Tesla quickly released an over-the-air firmware update, to every Model S ever manufactured, that would resolve the security holes uncovered by Rogers and Mahaffey.
The Tesla Hack
Rogers and Mahaffey had to dismantle the dashboard to gain access to an ethernet port. From there, they were able to connect directly to the CAN bus, the controller area network across which car data is sent and received.
After that, they chained together four separate vulnerabilities, first to gain access to the infotainment systems and then the touchscreen used to control vehicle functions. That let them make the speedometer disappear, alter the suspension, unlock the doors and the trunk, and make the windows go up and down. They were also able to shut down the car’s electric motor below 5 mph.
Above that speed, the dashboard screens would go blank but the car would shift into neutral, giving the driver time to find a safe place to bring the car to a stop. “Ironically, that means it’s the only car that can protect itself against a successful cyber attack,” Rogers noted.
Tesla’s Response
“Tesla has taken a number of different measures to address the effects of all six vulnerabilities reported by Lookout. And, we continue to develop further ways to harden our systems, informed by ongoing discussions with the security research community, as well as our own internal analysis. The update has been made available to all Model S customers through an OTA update. We will deploy this update to all vehicles by Thursday,” a spokesperson said in a statement e-mailed to Forbes.
Other auto manufacturers are following in Tesla’s footsteps by making internet updates available for their upcoming line of vehicles, but are starting years behind Tesla.
Rogers and Mahaffey say they also found two potential browser vulnerabilities that they exposed but did not exploit. Those flaws, resident in the WebKit browser engine, could possibly have enabled remote attacks, but Tesla’s new firmware update has resolved those issues as well.
Tesla CTO Toasts Hackers
While Rogers and Mahaffey were explaining their hacks at Def Con 23 last Friday, Tesla CTO J. B. Straubel made a surprise appearance to offer them a toast and personally thank them for their work. J.B. presented the duo with “Challenge Coins,” which will Tesla will be giving to any researcher who finds a serious security hole in their vehicles.

Tesla's approach to distribute vulnerability and feature updates through over-the-air technology, similar to how one updates software on their mobile device, clearly puts it steps ahead of other automakers.
Chris Evans, who previously worked on Google’s elite Project Zero research team, became head of digital security at Tesla this past week. He was involved in the software update that the company has now sent to all customers. “This gives me really high hopes with Tesla going forward," says Mahaffey. “I would like to see what they’ve done as a reference model for others. I think they’ve got lessons to learn but they’re 75 per cent there."
As cars acquire more digital capability, the opportunities for outside interference either by "white hat" hackers or those bent on doing actual harm will increase. Tesla, though, has the most robust program for identifying and resolving digital security issues of any manufacturer. That commitment should give every Tesla owner and prospective owner a full measure of confidence in the integrity of Tesla automobiles, now and in the future.

Tesla makes last-ditch effort to get CEO Elon Musk $56 billion payday

Tesla has made a last-ditch effort to secure the $56 billion pay package for CEO Elon Musk, which was approved twice by company shareholders, after a Delaware Chancery Court denied the frontman the payday.
Perhaps one of the biggest issues from a standpoint of being fluent in Tesla-related events has been Musk’s pay package.
It was approved by shareholders once in 2018, and required Musk to oversee various growth tranches that would bring investors value. He completed each of the tranches and was entitled to the pay package.
However, the Delaware Chancery Court decided in January 2024 to rescind the pay package, which Musk had earned, based on a suit filed by a shareholder.
Chancellor Kathaleen McCormick ruled that Tesla’s board lacked independence from Musk when the pay package was approved in 2018, and that it should not be granted.
She called it “an unfathomable sum.”
In response to the pay package’s rejection by Chancellor McCormick, Tesla held a second shareholder vote last year, which once again showed investors were willing to support Musk’s payday. It was approved by shareholders, but it was once again denied by the court.
Today, Tesla attorneys argued to the Delaware Supreme Court that the pay package should be restored because of last year’s vote by shareholders.
Jeffrey Wall, an attorney for Tesla, said (via Reuters):
“This was the most informed stockholder vote in Delaware history. Reaffirming that would resolve this case. Shareholders in 2024 knew exactly what they were voting.”
In a response to the decision by the Delaware courts last year, Tesla proposed a new pay package for Musk in September, which would give him a potentially $1 trillion compensation plan. It would require Musk to help Tesla reach several performance-based growth milestones, including achieving an $8.5 trillion market cap.
Elon Musk’s new pay plan ties trillionaire status to Tesla’s $8.5 trillion valuation
Musk is currently worth $483 billion, making him the richest person in the world. If he were to achieve his pay package tranches, granted the new pay package is passed at the Shareholder Meeting in November, he would easily be the first trillionaire.

Tesla makes big move with its Insurance program
Tesla Insurance launched back in late 2019, and it was massive because it was the first time a company aimed to cover its vehicle owners in-house without the need for third-party companies.

Tesla Insurance is heading to a new state for the first time in years, as the company is aiming to launch its in-house coverage platform in Florida.
Tesla Insurance launched back in late 2019, and it was massive because it was the first time a company aimed to cover its vehicle owners in-house without the need for third-party companies.
Tesla Insurance goes live with claims of lower rates by 20-30%
However, it has struggled to expand and only offers insurance in twelve states currently.
Tesla Insurance is available in:
- Arizona
- California
- Colorado
- Illinois
- Maryland
- Minnesota
- Nevada
- Ohio
- Oregon
- Texas
- Utah
- Virginia
In California, Tesla cannot offer real-time insurance or telematics due to regulatory rules.
The company uses a Safety Score to adjust rates based on driving behaviors. The current version, which is called Safety Score Beta v2.2, tracks Hard Braking, Aggressive Turning, Unsafe Following, Excessive Speeding, Late-Night Driving, Forced Autopilot Engagement, and Unbuckled Driving to determine the rate it should charge.
Tesla is working to expand into new markets and has filed applications to launch the program into new U.S. states. Back in 2022, it filed to offer insurance to Florida drivers, but it did not launch.
However, the company just filed to update its Private Passenger Auto program in Florida, according to the insurance site CoverageR.
It would be the first new state to obtain Tesla Insurance since Utah and Maryland launched over three years ago.
Tesla has its eyes on other states, including Georgia, New Jersey, Oregon, and Virginia.
It has also tried to expand to Europe, as it opened an office specifically for Insurance. It was also hiring for Legal Counsel specializing in Insurance on the continent, but nothing ever expanded to an actual offering of vehicle coverage.
Tesla Insurance is an advantage for owners specifically because the company is familiar with its vehicles, the parts, and the repair processes that are required to get a car back on the road.
This was a big reason some drivers switched from the previous providers to the in-house Insurance Tesla was able to offer.

Tesla launches new interior option for Model Y
Tesla just launched a new light grey interior option for the Model Y L in China, which will cost $1,120.

Tesla has launched a new interior option for the rare Model Y L trim that is available only in China, marking the first new color for the inside of a vehicle in some time.
Tesla has traditionally stuck with either Black or White interior options with the Model 3 and Model Y, although the Model S and Model X have had additional colors. The Model S and Model X still have a Walnut Cream interior option that costs an additional $2,000.
With the mass market models, however, Tesla has maintained the Black or White selections, until now, at least in China.
Tesla just launched a new light grey interior option for the Model Y L in China, which will cost $1,120.
It differs from the white interior slightly, but it is nice for buyers in China to have this third option:
The new color is only available on the Model Y L in China, so customers who take delivery of other trim levels or in other regions will not have this color available to them, just as the vehicle configuration itself is exclusive to that market.
In terms of whether it will make its way to other markets, CEO Elon Musk has said that the Model Y L could potentially make its way to the United States at the end of 2026, but it is not a certainty.
Musk said:
“This variant of the Model Y doesn’t start production in the U.S. until the end of next year. Might not ever, given the advent of self-driving in America.”

This came as a disappointment to many fans and owners in the U.S. because people here have been pushing Tesla to create and manufacture a new, full-size SUV, or at least something more traditional that competes with vehicles like the Chevrolet Tahoe and Ford Expedition.
While the Model Y L is not on par with the size of those vehicles, it is a longer and larger version of the best-selling Model Y.

Nevertheless, the new interior option is something we could hopefully see added to U.S. vehicles, although it seems Tesla’s focus is truly dialed in on the Cybercab and expanding Robotaxi and autonomy.
