WhatsApp’s biggest privacy disaster ever: 3.5 billion profiles exposed

https://www.pcworld.com/article/2976420/whatsapps-biggest-privacy-disaster-ever-3-5-billion-profiles-exposed.html

Researchers from the University of Vienna and SBA Research did something pretty astonishing: they were able to retrieve all existing WhatsApp numbers. In fact, they were able to view and analyze an incredible 3.5 billion WhatsApp profiles, making this one of the largest data collection efforts in history.

According to the researchers, all existing WhatsApp profiles were unprotected on the web and they were able to download all phone numbers and their associated profile data. The researchers informed Meta (owner of WhatsApp) about this leak back in September 2024, but Mark Zuckerberg’s company didn’t respond at first. (Incidentally, Meta is being sued by a former WhatsApp security chief!)

Meta’s initial lack of interest is all the more surprising when you consider everything that emerges from this freely accessible data. For example, we can determine how many WhatsApp users there are per country and how they’re distributed between Android and iOS. India has the most WhatsApp users, followed by Indonesia and Brazil.

The association of WhatsApp accounts to certain countries isn’t as harmless as it may sound. In authoritarian states where the use of WhatsApp is banned and/or monitored—such as North Korea, China, and Myanmar—it can be life-threatening for the owners of certain phone numbers if state surveillance bodies can analyze this data.

Sensitive data freely accessible

Around 30 percent of WhatsApp users have entered detailed information about themselves in their WhatsApp profiles, including sexual orientation and/or political views. Some users have even mentioned their drug habits, while others (who are obviously drug dealers) have mentioned their drug supply and operations. Links to Tinder and OnlyFans posted on WhatsApp were also freely accessible.

Some WhatsApp profiles were also registered using email addresses associated with government and military organizations. Many profiles contained photos in which the users can be clearly identified.

In other words, all of this freely accessible WhatsApp data could be used to synthesize full identities complete with phone numbers, photos, preferences, and email addresses. The researchers also found security problems with some public keys of WhatsApp accounts.

What you can do about this

Based on the findings, we recommend that all WhatsApp users keep their profile information as limited as possible and refrain from posting photos in which they can be identified. Also, don’t provide any links to dating profiles or other sites that could be detrimental to you.

The full research paper—entitled “Hey there! You are using WhatsApp: Enumerating Three Billion Accounts for Security and Privacy”—is published for free on GitHub.

A California Startup Just Flew Its $190,000 All-Electric Flying Car for the First Time

https://www.autoblog.com/news/a-california-startup-just-flew-its-190000-all-electric-flying-car-for-the-first-time

A California-based startup has completed a public test flight of its single-seat, all-electric flying car, taking a major step toward consumer-oriented personal aviation. The demonstration, held at the Center for Automotive Research in Northampton County, North Carolina, saw the craft climb to roughly 150 feet and complete a low-altitude circuit. Priced around $190,000, the vehicle is aimed at individual owners rather than air-taxi fleets, and the company’s test pilot went as far as saying, “Everybody’s going to have one.”

The prototype, developed by Pivotal Aero, uses a lightweight electric VTOL layout and reportedly offers about 25 miles of range with speeds near 60 mph. Under current FAA ultralight-style rules, early models may not require a traditional pilot’s license, though flights are restricted to uncongested areas and daylight operation. The company is pitching it as a recreational or short-hop personal aircraft while it pursues broader approvals.


A Glimpse Into the Future of Flying Cars

The test flight arrives at a moment when hype around airborne personal vehicles is increasing again, especially after claims like those surrounding Tesla’s next-generation Roadster. While Tesla’s concept leans more toward futuristic hovering technology than true eVTOL operation, it reflects the same momentum now seen in Pivotal’s real-world prototype.

Still, the practicality of these machines is far from proven. Regulatory oversight, infrastructure gaps, and the limitations of current battery technology are major hurdles, and safety remains a central question. Recent incidents across the emerging eVTOL field, including a recent one in China, show the need for strong certification and reliability standards before any mass rollout.

Why This Matters

Pivotal’s prototype suggests that the “personal flying car” niche may grow faster than expected, but only for affluent early adopters. The current price, short range, and restricted-use rules make it more of a specialized recreational aircraft than a mass-market mobility product.

Still, the significance goes beyond hobbyist appeal. As major automakers push into electrification, including Toyota’s new mainstream efforts, the broader transportation landscape is shifting rapidly. Personal electric aircraft represent another branch of that evolution, merging automotive-style usability with simplified aviation.

What Comes Next

To move beyond demos, companies like Pivotal must secure FAA certifications, expand battery capacity, boost flight time, and build the infrastructure for charging and maintenance. Urban airspace regulation, noise standards, and emergency procedures will also shape how, and where, these vehicles can fly.

Even with massive hurdles ahead, the successful test flight is a reminder that the line between cars and aircraft is blurring. Whether these machines become common or remain niche, the first wave of all-electric flying cars has officially left the ground.

Open-Source Software for 3D Printing with Multiple Materials

https://www.techbriefs.com/component/content/article/54191-open-source-software-for-3d-printing-with-multiple-materials

Tech Briefs: What got you interested in this project?

Charles Wade: I’ve always been interested in 3D printing in general, especially the design side. Growing up I struggled to understand engineering, especially math, but 3D printing provided a tactile and visual way to do it. So, that’s what got me into this — I can do what I do as a computer scientist, write code, and also fabricate something in the real world that I can touch and feel.

California Startup Flies Military Version of Its Air Taxi for the First Time

https://gizmodo.com/california-startup-flies-military-version-of-its-air-taxis-for-the-first-time-2000686221

Just three months after announcing a partnership with defense contractor L3Harris, Joby Aviation flew the new hybrid version of its flying car concept that’s been repurposed for military use.

The first flight of the turbine electric, autonomous vertical take-off and landing aircraft took place on November 7 at the company’s facility in Marina, California, Joby announced on Thursday. The California startup is known for developing all-electric air taxis for short, yet pricey, trips in places like Dubai and Saudi Arabia. Its new hybrid aircraft, however, is geared toward defense customers.

“It’s imperative that we find ways to deliver new technology into the hands of American troops more quickly and cost-efficiently than we have in the past,” JoeBen Bevirt, CEO and founder of Joby, said in a statement.

Prepare for takeoff

The new aircraft builds on Joby’s existing technology for its air taxis, integrating a hybrid turbine powertrain with the company’s SuperPilot autonomous flight system. That way, the new aircraft is designed to carry heavier payloads and travel longer distances than the current battery-powered version.

Through its partnership with L3Harris, Joby will also add sensors, surveillance, communications systems, and mission equipment onto the aircraft so that its vehicle can be repurposed for use by the military.

“The magic of dual-use technology is that it creates value in both directions,” Bevirt said. “By building on our proven technology stack, our partners can rapidly deliver new capabilities for the Department of War while we benefit from advancing the maturity of our hybrid and autonomous systems.”

Joby is hoping to cash in on a growing demand by the U.S. military for autonomous and hybrid aircraft. The company noted that the government has allocated roughly $9 billion in the 2026 budget to go toward developing next-generation aircraft.

“The next generation of vertical lift technology enables long-range, crewed-uncrewed teaming for a range of missions,” Jon Rambeau, president of Integrated Mission Systems at L3Harris, said in a statement. “We share a vision with Joby to deliver urgently-required innovation by missionizing VTOL aircraft for defense applications.”

Joby will continue to test its new aircraft on the ground and in flight, and the company is hoping to begin operational demonstrations with government customers by next year.

Porsche’s New $8,000 Wireless Charger Could Change EV Ownership Forever

https://www.autoblog.com/news/porsches-new-8000-wireless-charger-could-change-ev-ownership-forever

A Potential Game Changer

A few months ago, Porsche showcased its wireless charging system for vehicles. It has all the potential to change the EV charging landscape, as it aims to reduce the need for wallboxes or large charging stations. With its compact packaging, Porsche says charging at home will be a lot easier. We also reckon it has a practical use in EV fleets, too.

It’s about to roll out soon and will be an optional extra for the upcoming Cayenne EV. The question is, how does it work?

Porsche

The Setup

The charging pad measures 2.3 inches tall, 78 inches wide, and 46 inches long. It’s then activated by the driver’s phone, and the charger and vehicle will request for a password to begin charging. Porsche says it only needs to be done once, and the system will automatically start the next time the vehicle drives over the pad thanks to an integrated wi-fi module.

The pad is plugged into a power source that then converts AC into DC voltage. The device weighs 33 pounds, or about as much as a toddler. One of the built-in safety features is that it automatically stops when an obstruction is detected (such as a pet or a curious child), and resumes once it’s no longer there.

Charge is transferred via two copper coils. A current is sent to one, while the second one amplifies it from the magnetic field generated by the system. That field allows wireless charging to be possible. It’s a similar arrangement to wireless chargers for mobile devices, but Porsche had to repackage it in a way that it remains compact enough for automotive application. Scaling up wasn’t an option.

Porsche

How’s the Charging Rate?

What’s interesting here is that charging plate has a voltage of 85 kHz and 2,000v in an oscillating circuit. That allows it to send a charge upwards into the vehicle’s battery if it’s not perfectly aligned by up to four inches. Of course, the car can’t trip up the charger if it’s way out of line.

All in all, the system produces 11 kW of charging power. For reference, most home charging systems out out 3 to 7 kW, while your typical public charging station does about 11 to 22 kW. Okay, it’s not a rapid charger, but at least it’s gentle on the vehicle’s batteries, ensuring battery health in the long run.

Porsche

Porsche says that it will continue to develop its vehicle wireless charging tech down the line. From there, we can expect quicker charging rates, as well as more clever packaging in years to come.

How much is it, then? It’s about $8,000 including installation at current conversion rates. Not exactly cheap as home chargers are about ten times less (sans installation), but at least it charges faster than most home systems. Well, nobody said that new technology ever came cheap.

As for the first-ever Porsche Cayenne EV, the full reveal will be on November 19.

‘Shockingly large’ amount of sensitive satellite communications are unencrypted and vulnerable to interception, researchers find

https://www.space.com/space-exploration/satellites/shocking-vulnerabilities-satellite-communications-study

Cybersecurity researchers have intercepted vast quantities of private voice calls and text messages, including potentially sensitive communications of government and military officials, transmitted over completely unprotected satellite communication links.

When the researchers decided to put satellite communications under scrutiny, they thought they would find some flaws. What they discovered was much worse than their wildest dreams. Using a commercial off-the-shelf satellite dish mounted on the roof of a university campus in San Diego, they scanned internet traffic routed via 39 geostationary satellites visible from southern California.

"A shockingly large amount of sensitive traffic is being broadcast unencrypted, including critical infrastructure, internal corporate and government communications, private citizens’ voice calls and SMS, and consumer Internet traffic from in-flight wifi and mobile networks," the researchers wrote in a statement. "This data can be passively observed by anyone with a few hundred dollars of consumer-grade hardware."

It turns out that many of these satellites are using outdated equipment, the researchers say. "Geostationary satellites are a somewhat older technology so our expectation was that they will be using some older, outdated cryptography," Dave Levin, an associate professor in computer science at the University of Maryland who led the research, told Space.com. "So, we thought we would try to listen and then see whether we could break this cryptography. It turned out we didn’t have to because the cryptography wasn’t used at all in large part."

Geostationary satellites orbit Earth at a distance of 22,000 miles (36,000 kilometers). At this distance, the orbital velocity of a satellite matches the speed of Earth’s rotation. As a result, the satellite appears suspended above a fixed spot on the equator, having a stable view of a large portion of the globe.

Before the advent of low-Earth-orbit internet-beaming megaconstellations such as SpaceX’s Starlink, geostationary satellites were the dominant solution for satellite communications. They are still widely used today, including for military purposes. The satellites scrutinized in the new study make up only about 15 percent of the world’s entire geostationary fleet, Wenyi "Morty" Zhang, a PhD researcher at the University of California, San Diego, and co-author of the study, told Space.com. He thinks the scope of the problem is likely much worse.

Levin said that what the team found was "as bad as one could hope." The researchers could listen to private phone calls, read text messages, but also see sensitive traffic transmitted by companies and government and military organizations. Data of passengers using in-flight WIFI provided onboard of commercial airliners were also easily visible.

"There were way more things in the clear than we had anticipated," Levin added. "Moreover, there were also more sensitive things than we had anticipated."

Zhang said the transmissions included messages sent by Mexican military and the police, and even some communications by the U.S. Government.

"It was quite shocking to us," said Zhang, who built the eavesdropping antenna and led the technical side of the project. The entire set-up, he said, cost a few hundred dollars and consisted of commercially available equipment.

The complete absence of encryption of the satellite links was only one part of the problem, added Levin. Hundreds of companies, frequently unaware of the workings of satellite communications systems, were sending their data via those satellites without end-to-end encryption, which is a standard in today’s secure internet communication.

Data being transmitted by hundreds of companies including mobile telephone operator T-Mobile were thus in plain sight of the researchers. The team has not yet disclosed the names of all the affected companies. They are bound by responsible disclosure rules that require them to give the affected parties time to fix the problems before making their issues public, but they stated that millions of users have been made vulnerable through the complete lack of encryption.

The researchers spent mere days investigating each of the satellites. Still, the amount of intercepted communications was mind-boggling. A dedicated attacker could easily harvest even more data. And in addition to gathering sensitive information, attackers could find many ways to actively exploit those vulnerabilities.

"Just from being able to see people’s text messages, you might be able to get their two-factor authentication codes and then log into systems as them," said Levin. "But an adversary could step up to another level and begin interjecting their own messages. They could, for example, try to interfere with critical infrastructure."

Levin added that although the affected companies first didn’t want to believe they had a problem of such a scope at their hands, they all responded "positively" and in many cases were not even aware how much of their data was transmitted via satellites.

The research was presented in the Proceedings of the 32nd ACM Conference and is available online.
