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.
Tesla Model S infotainment system also serves as the command center to the vehicle.
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 (NASDAQ: TSLA) will report its earnings for the second quarter of 2026 this evening after market close, and investors and analysts are waiting anxiously to see what the company will report for the second three-month span of the year.
Analysts have already put out their expectations from a financial standpoint for the company’s second quarter, but what’s unknown is what Tesla plans to discuss during the call.
Financial Expectations
Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.53, while revenues are expected to come in around $26.4 billion.
This would compare to an EPS of $0.39 and $22.19 billion compared to Tesla’s Q2 2025. Last quarter, EPS came in at $0.41 on $22.387 billion of revenue. Additionally in Q1, Tesla beat analyst expectations, but shares dropped over 3 percent the following trading day.
What We Expect
In terms of discussions, Tesla earnings are pretty sporadic and depend on a handful of things, including current events, investor questions, and more.
Tesla uses a platform called Say to field questions from investors and analysts. These questions are what will be used during the call. Here are the top 5 from the Retail side and top 3 from the Institutional side:
Retail:
“Tesla has missed short-term guidance on robotaxi 3 earnings reports in a row, from 50% coverage of USA by end of 2025 to most recently 7 new cities in 1H26. What is keeping Tesla back from accomplishing these short term goals that they’ve set for themselves?”
“What are the main constraints to expanding robotaxi operations faster, and how do you see that lining up with Cybercab production?”
“What’s the current status of Optimus Gen 3 production ramp, initial deployment in factories, and external sales timeline/volume for 2027? What tasks can we expect the Optimus to perform by end of 2027?”
“To reward long-term Tesla retail shareholders for their loyalty, can you commit to achieving at least half of the goals outlined in your 2025 compensation plan before considering any offers to acquire or merge Tesla?”
“Why has growth of robotaxi vehicles stalled? When will we see cybercab start customer rides?”
Institutional
“Previously, you’ve said Tesla would lead the R&D while SpaceX would lead production for Terafab. Can you provide an update on how that division of responsibilities is evolving, and any additional clarity on the expected capital contributions from Tesla and SpaceX?”
“For autonomous driving, Tesla’s fleet created a huge data advantage by collecting billions of real-world miles. That advantage doesn’t yet exist for Optimus. How should we think about data availability and its impact on Optimus development?”
“Why is it necessary to limit robotaxi operations within specific zones within cities to start? Will every city have to be rolled out this way?”
Tesla will report earnings for Q2 this evening with the Shareholder Deck at 4 p.m. ET, with the call starting around 5:30 p.m. ET.
Elon Musk
Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
