Flickr discloses potential data breach exposing users’ names, emails

Published

on

Flickr

Photo-sharing platform Flickr is notifying users of a potential data breach after a vulnerability at a third-party email service provider exposed their real names, email addresses, IP addresses, and account activity.

Founded in 2004, Flickr is one of the world’s largest photography communities and sharing sites, hosting over 28 billion photos and videos. The company says it has 35 million monthly users and 800 million monthly page views.

Flickr did not disclose which third-party provider was involved or how many users were potentially affected by this incident. A Flickr spokesperson was not immediately available for comment when contacted by BleepingComputer earlier today for more details.

The company said that it shut down access to the affected system within hours after being informed of the security flaw on February 5. While the vulnerability “may have” provided access to some member information, Flickr said that passwords and payment card numbers were not compromised in the incident.

“On February 5, 2026, we were alerted to a vulnerability in a system operated by one of our email service providers,” the company said in emails to affected users. “This flaw may have allowed unauthorized access to some Flickr member information. We shut down access to the affected system within hours of learning about it.”

The exposed information includes member names, email addresses, Flickr usernames, account types, IP addresses, general location data, and their activity on the platform.

The company has also encouraged affected users to review their account settings for any unexpected changes and to remain vigilant against phishing emails that may use their Flickr account information, noting that it will never request passwords over email.

Users are also recommended to update their passwords as soon as possible if they use their Flickr credentials on other services.

“We sincerely apologize for this incident and for the concern it may cause,” Flickr added in the emailed notifications.

5 Best Video Doorbell Cameras (2026): Smart, Battery, AI, Budget, and Subscription-Free

Published

on

Other Video Doorbells to Consider

I’ve tested several other video doorbells. These are the ones that narrowly missed out on a place above.

SwitchBot Smart Video Doorbell for $100: I don’t love the design of this wide doorbell, but it does come with a wee display that you can use to view who’s there and answer. This could be handy for folks who don’t want to rely on a phone and it lets anyone in the house check who is calling. Video quality is decent, though the frame rate is limited to 15, and the display is low res. You can record locally, and there’s a subscription option if you want cloud storage. Sadly, I found the display was often slow to wake up, and sometimes I had trouble playing back recorded videos.

Philips Hue Secure Video Doorbell for $170: After a fiddly installation, you get a stylish doorbell offering sharp 2K resolution day or night and a wide view that takes in your whole porch. Notifications are swift and reliable, and you can sync up your Hue lights in interesting ways, but if you don’t already have a Philips Hue setup, I’d pick something from above. There’s no local storage option and you must buy a Smart Chime separately. Although you can get 24 hours of video for free, the false alerts will drive you mad. You must subscribe (from $40 a year) to get vital features, like people detection, activity zones, and back-to-back video recording.

Wyze Battery Video Doorbell for $66: Another solid budget option, you get decently sharp 1536 x 1536 resolution video with a 150-degree field of view from this doorbell. You can record locally on a microSD card and there’s good smart home connectivity, but you need a Wyze subscription, from $3 per month, to get person, package, pet, and vehicle detection, back-to-back video recording, and rich alerts (it’s not worth getting without this subscription). The indoor chime is sold separately, and if you want advanced features like facial recognition or descriptive alerts you have to pay more ($10 or $20 a month).

Logitech Circle View Doorbell for $200: As close as you can get to an Apple video doorbell, this compact hardwired doorbell boasts a 160-degree field of view with a 3:4 portrait aspect ratio that takes in your whole porch. Video is crisp and clear, in bright or low light, and the live feed is impressively quick to load. The notification system can tell the difference between animals, people, and vehicles, and will start to recognize familiar faces over time. It works directly through the Apple Home app, though there are pros and cons to Apple’s HomeKit Secure Video. Ten days of encrypted videos are stored in your iCloud account (if you have a 50-gigabyte subscription or higher). Alerts come via Apple devices, but your regular chime will also sound when this doorbell is pressed. I love that live video pops up on the Apple Watch or Apple TV when someone rings the doorbell. The complete lack of support for Android or Alexa will turn some people off, and I encountered several issues with this doorbell cutting out and having to be rebooted at the fuse box.

Amazon Blink Doorbell for $70: One of the cheapest doorbells worth considering, (wait for one of Amazon’s frequent discounts to save even more) the Blink Video Doorbell only needs two AA batteries to run for months. But you need a subscription unless you buy with the Sync module (I recommend it). The Blink Basic subscription is $3 a month or $30 a year. Video quality is 1080p with a limited field of view (135 degrees horizontal and only 80 degrees vertical). The lack of HDR shows in mixed light, with bright areas blowing out and shaded areas losing detail. If you have a person at the door with light behind them, it can be tough to see their face. Notifications lacked images or video and were slightly slower than some of the competition, but they always came through. The two-way audio is passable.

Nest Doorbell (Battery) for $180: If you can’t hardwire your doorbell, the battery version of our top pick is still a great doorbell. I tested it alongside several competitors, and it consistently outperformed them. Alerts are swift, and notifications include animated previews that make it easy to decide whether you need to act. While the resolution isn’t the sharpest (960 x 1280 pixels), and the field of view is 145 degrees, Google compensates with HDR video at up to 30 frames per second.

Doro Hemma Doorbell for £150: A simplified smart doorbell for seniors is a solid idea, and Swedish maker Doro gets plenty right with the Hemma. It is a battery-powered doorbell that’s easy to install and use, offering a 1440 x 1440-pixel resolution with a decent frame rate (30 fps), local recording via microSD card, and a plug-in ringer that gets loud enough to hear throughout the home. It worked reliably during testing, and the mobile app is deliberately straightforward, with a handy option to pass calls off to a trusted friend or family member (they’ll need the app too). The two-way audio works well, there’s a handy zoom function when you livestream, and there’s a siren to scare folks away. It is simplified, so there are no privacy zones or package alerts, and it may be too sensitive for busy front doors, though you can set it to alert just for doorbell rings. Battery life is decent, though the battery is not removable, so you need to take the doorbell off to charge or use a portable charger. Sadly, it is only available in the UK and Europe.

SimpliSafe Video Doorbell Pro for $170: If you’re looking for a solid security system, SimpliSafe is likely on your radar, and for folks with a SimpliSafe setup, the Video Doorbell Pro fits in neatly. Former WIRED reviewer Medea Giordano found it sensitive at first, but, after an update, she says it worked nearly perfectly, sending swift alerts and offering a good, clear view of her porch. Footage maxes out at 1080p, but the camera supports HDR to banish glare and has a 162-degree field of view. It does have to be wired, and you need a subscription from $5 per month to record videos, but SimpliSafe also offers the option of professional monitoring (from $32 per month), which is a rarity for doorbells and might make sense if you have a complete security system with them.

TP-Link Tapo (D230S1) Smart Battery Video Doorbell for $106: For folks seeking a local storage option that doesn’t require a monthly fee, Tapo’s smart video doorbell is worth a look. Notifications come through swiftly and include a still image; video quality is excellent, even at night, and the indoor hub takes a microSD card and doubles as a chime. On the downside, it is chunky, and the onboard AI (which is supposed to recognize people, pets, vehicles, and packages) is flaky.

Tough to Recommend

We didn’t like every video doorbell we tested. These are the ones we don’t recommend.

Imou Doorbell 2S Kit: Aside from being large and ugly, the Imou doorbell offers crisp video recording up to 2K with a 166-degree field of view, and it has a unique trick: the lens can rotate through 30 degrees to track subjects. The large size allows for a big battery, but this doorbell can also be hardwired. The kit includes a plug-in chime with a microSD card slot for local storage. Unfortunately, testing side by side with the Arlo, it failed to pick up some events. I also had major connection issues after changing my router, despite retaining the same network name and password. I had to reset the chime, which temporarily deleted the doorbell. It’s only available in the UK.

Reolink Video Doorbell (Battery): We liked Reolink’s wired doorbell, listed above, so I was excited to try its first battery-powered model, but it was a disappointment. It offers up to 2K footage with a 1:1 aspect ratio that gives you a complete view of the porch, but you must turn HDR on in the settings, and it has a relatively low frame rate (15 fps). I like the option to go subscription-free, but it means putting a microSD card in the doorbell itself, and this is a relatively easy doorbell to remove. Reolink suggests up to five months of battery life, but my first review unit died after less than two and refused to recharge. Reolink sent me a replacement, which is performing better, but when it does run out, the rechargeable battery inside cannot be removed, so you have to take the doorbell off to recharge it. Factor in the slightly confusing app, relatively slow loading times, and connection glitches, and this is impossible to recommend.

Ezviz EP3x Pro

Ezviz EP3x Pro: This is a far better-looking doorbell than Ezviz’s previous models, and it’s nice to see solar panels as an option for doorbells, though you will need a porch capable of catching some rays. The video quality is good, and you get a split view (like the Eufy above) that includes packages or waiting cats on your doorstep. The distortion correction works well, and there is optional color night vision with a built-in light, though it only works at very close range. I appreciate the 2FA, with fingerprint login, and 32 GB of onboard storage (cloud storage is an optional extra). Sadly, if you use the solar panel, you can’t connect to your wired chime. The lack of HDR is disappointing, human detection was a bit off (it frequently said I was a cat), and I had issues with alerts failing to come through on some Android phones. (Even after following Ezviz’s instructions, they never worked reliably on my Xiaomi 14 Ultra.) This model is not yet available in the US.

Botslab Video Doorbell 2 Pro: The flaky setup procedure required a couple of restarts, and physical installation was no better, as the screws supplied were so cheap that one of the heads broke off. The camera has a fisheye effect, but you can correct it with different views. I liked the VR mode, which provides a 180-degree view of your front porch. It comes with a handy plug-in chime, alerts seem reliable, there is an HDR option, and you can record locally (32 GB included) or in the cloud. You can also set a detection range, which could be handy for street-facing cameras. But the app is confusing, with an AI tab that lists various skills available for purchase. There is a login history and a limit of two devices signed in at once, but no 2FA, which makes this impossible to recommend. It is versatile but also relatively expensive.

Swann SwannBuddy Video Doorbell: This doorbell comes with a wireless battery-powered chime and the option of local storage, but the positives end there. The video quality is poor, the app is painfully slow to load and glitchy, and the doorbell frequently fails to register motion. I found the battery life disappointing. I must also question the decision to provide local storage via a microSD card inserted in the doorbell (the chime would make more sense and be more secure).

What Features Should I Look for in a Video Doorbell?

Advertisement

Here are a few factors that you might want to think about when shopping for a new video doorbell.

Resolution and HDR: The higher the resolution, the clearer the picture you get, but consider that higher-resolution video also requires more bandwidth to stream and takes up more storage space. If your front porch is in direct sunlight or strong shade, I strongly recommend opting for a video doorbell with HDR support, as it helps to prevent bright areas from appearing blown out or shadowy areas from being too dark to see.

Field of view and aspect ratio: If you want a head-to-toe view of the person at your front door, then think about the field of view and aspect ratio offered by your prospective pick. A wider field of view will take more in but can cause a fish-eye effect. Rather than a traditional landscape aspect ratio, you may prefer a square or portrait view to ensure you can see a visitor’s face and any packages that might be on your porch.

Local or cloud storage: If you don’t want to sign up for a subscription service and upload video clips to the cloud, ensure your chosen doorbell offers local storage. Some video doorbells have microSD card slots, while others record video to a hub device inside your home. You can expect to pay somewhere around $3 to $10 per month for 30 days of storage for a video doorbell.

Advertisement

Advanced features: The best doorbell cameras offer features like package detection and person recognition. These features can be handy for filtering alerts, so you only get useful notifications. Bear in mind that you may need a subscription to gain access to advanced features.

Security: A couple of things I recommend looking for are two-factor authentication (2FA) to ensure that someone with your username and password cannot log into your doorbell, and encryption to ensure that anyone accessing the manufacturer’s servers cannot see your Wi-Fi login details or watch uploaded videos.

Which Is Better, a Wired or Wireless Video Doorbell?

Smart doorbells require more power than traditional doorbells. If you opt for a wired video doorbell, you may need a new transformer, and you will likely want to hire an electrician for safe installation. The main advantages of wired doorbells are that you shouldn’t need to touch them again after installation, and they will ring your existing doorbell chime. Wired doorbells are usually a bit cheaper and slimmer than models with batteries, too.

Advertisement

Battery-powered smart doorbells are easy to install yourself and can be mounted wherever you like. The main downside is that you must remove and charge the battery every few weeks or months, which means some downtime unless you buy a spare battery to switch in. Remember also that your regular doorbell chime won’t work with a battery-powered smart doorbell, so you will probably need to buy a wireless chime device to plug in somewhere in your home, though you can also configure smart speakers to act as doorbell chimes.

Most battery-powered video doorbells can also be wired, which may be the best solution if you have concerns about power outages. Wired doorbells are generally faster to alert and more reliable than battery-powered doorbells.

How Well Do Video Doorbells Perform?

All smart doorbells need a strong Wi-Fi signal to perform well. Some come with hubs that double as Wi-Fi repeaters for a better connection. Remember that performance away from home when you access the video doorbell on your phone will be heavily impacted by the quality of your phone’s internet connection. Every video doorbell I’ve tested has a slight lag, but you should be able to see the live feed in close to real time and carry on a two-way conversation. While feeds should load within two to three seconds, occasional delays in loading the live feed are common, and I have yet to find a flawless doorbell. Video doorbells tend to load fastest in their native app.

What Is the Best Video Doorbell Brand?

While Google’s Nest Doorbell is our top pick, it might not be the best video doorbell for you. If you already have a security camera system or plan on getting one, it makes a lot of sense to stick with the same brand for your doorbell. That way, you can access everything in the same app and get a single subscription if required. If you have a lot of smart home devices, check that the doorbell is compatible with your preferred ecosystem and voice assistant.

Why We Hesitate to Recommend Ring

I’ve been testing video doorbells for several years now. I install every video doorbell I test and use it for at least two weeks, but usually longer, as our main doorbell. I check the responsiveness when at home and away, test all the features in the app, and explore the smart home integration options. After the initial test, I install the doorbell alongside other doorbells (usually at least our top pick) and directly compare the response time and accuracy of alerts.

Microsoft pulls KB5079391 Windows update over install issues

Published

on

Windows 11

Microsoft has pulled a buggy Windows 11 non-security preview update to investigate a known issue that triggers 0x80073712 errors during installation.

KB5079391, the problematic optional cumulative update, started rolling out on Thursday to Windows 11 24H2 and 25H2 systems with 29 changes, including Smart App Control and Display improvements.

This preview update also improved Windows Hello Fingerprint reliability on some devices and Windows Recovery Environment (Windows RE) stability when running x64 apps on ARM64 devices.

On affected devices, customers are seeing errors saying that “Some update files are missing or have problems. We’ll try to download the update again later. Error code: (0x80073712).”

Microsoft has now stopped the KB5079391 rollout but hasn’t shared a timeline for when a fix will be available. However, this will most likely happen before the next month’s Patch Tuesday cumulative updates are released on April 14 to allow customers to test the new features and fixes before they roll out to all users.

“Rollout of this update is temporarily paused due to installation error 0x80073712,” Microsoft said in an update to the original support document.

“To prevent additional impact while the issue is investigated, Microsoft has temporarily limited the availability of this update. As a result, the update temporarily might not be offered through Windows Update.”

One week ago, Microsoft released an emergency update to address another major issue triggered by the March 2026 Windows updates that was breaking sign-ins with Microsoft accounts across multiple Microsoft apps, including Teams, the Edge web browser, Microsoft 365 Copilot, and OneDrive.

Since this month’s Patch Tuesday updates were issued, Microsoft has also pushed two other out-of-band updates for hotpatch-enabled Windows 11 Enterprise devices to address a Bluetooth device visibility bug and security flaws in the Routing and Remote Access Service (RRAS) management tool.

It also shared guidance for fixing C:\ drive access issues on Samsung Windows 11 laptops caused by a buggy version of the Samsung Galaxy Connect (or Samsung Continuity Service) app.

Automated pentesting proves the path exists. BAS proves whether your controls stop it. Most teams run one without the other.

This whitepaper maps six validation surfaces, shows where coverage ends, and provides practitioners with three diagnostic questions for any tool evaluation.

Sora’s shutdown could be a reality check moment for AI video

Published

on

OpenAI announced this week that it’s shutting down its Sora app and related video models just six months after launching the app.

On the latest episode of TechCrunch’s Equity podcast, Kirsten Korosec, Sean O’Kane, and I debated what the decision means for OpenAI and for the industry more broadly. To some extent, the move seems consistent with what we’ve been hearing about OpenAI as it focuses on enterprise and productivity tools ahead of a possible IPO.

In fact, Kirsten suggested that OpenAI’s decision to shutter Sora was “a sign of maturity that was nice to see in an AI lab.”

But Sora’s shutdown — along with ByteDance’s reported delay in launching its Seedance 2.0 video model worldwide — could also be a reality check moment for the makers of AI video tools, and for evangelists who claim these tools will be replacing Hollywood anytime soon.

Read a preview of our conversation, edited for length and clarity, below.

Anthony: I think it’s worth highlighting that it’s not just the app. I mean, the app was particularly unappealing to me, at least, and I think to other people, because it was this idea of a social network without people, where it’s just nothing but slop.

But beyond the app, it seems like OpenAI is basically winding down pretty much everything it’s doing with video. According to the Wall Street Journal, which broke some of this news, it’s really about this idea that Open AI is — in advance of potentially going public — really trying to focus on business products, enterprise products, programming products. [So] this consumer social app, [and] more broadly video, is not a priority right now.

Sean: Yeah, I never really used [the app]. The idea of it turned me off for a number of different reasons. And you know, it was a good reminder that Open AI — and I don’t mean this to knock them down in really any way —  but I think this was a reminder, probably, for them internally, of the element of luck […] in how successful ChatGPT became. 

Clearly, there is something that is valuable there to people, I don’t want to take away from that, because you do not get to the usage numbers that we’ve heard reported from them without there being something that is working right —and even more so that it’s been kept up over a number of years and developed into something that stays meaningful to people.

But there was an element of Sora, when it came out, of like, “We built the most successful consumer product ever, and now we’re doing it again. And we’re going to bring in Disney and all this stuff.” I think this is just a really harsh reminder of like it’s not always going to be an absolute shortcut to the top of the greatest consumer products ever and that there really needs to be something that people feel like they’re getting some meaning out of it for it to stick around. 

Kirsten: Yeah, I actually want to give OpenAI props for this decision, because we sometimes make fun of the whole idea of “move fast and break things,” but I think that there is some value [to] companies that can iterate very quickly and then kill off products that are not working and not feel a sense of failure behind it. I mean, there was real money that was lost. If you were to look at the deal with Disney, that was a billion dollar deal, but if you look at — and we don’t have the insight into this because we’re not seeing their balance sheets — but what were they spending on this and what was the long-term value for the company? 

Advertisement

And I think that while, sure, it was interesting to see what they could create, their decision to shutter it, to me, showed a sign of maturity that was nice to see in an AI lab.

Anthony: In terms of what it means for OpenAI, it seems very consistent with everything that we’ve been hearing about their strategy going forward. It doesn’t seem like a huge blow or anything like that in terms of how we think about the future of generative AI.

Particularly in video, it’s interesting because it also comes at this time that there’s been reporting around Seedance, which is the ByteDance generative AI model [for video]. There’s reports that [Seedance 2.0 has] been delayed because there’s engineering and legal questions and basically [figuring out], “Can we build IP protections into this?” Which apparently they hadn’t taken as seriously before. 

And so, it’s this reality check moment. There were these really hyperbolic statements, including from people within Hollywood that [were] like, “We’re done, this is the future, it’s just typing in prompts and making feature films.” And it turns out that for all kinds of technical and legal reasons, it is not that easy and we are very, very far from that happening.

Advertisement

Sean: And the last thing I think we should say about this, too, is this is one of a number of decisions that appear to be happening after Fidji Simo came in [and began] sort of running the day-to-day operations. That’s just a huge dynamic that’s changed inside of OpenAI. And I think the further we get away from that moment of of her being tapped to run the show, and especially these consumer products and decide the fate of them, the easier it’ll be to look back at this moment in time and think about how big a moment that was for this company.

Every Path Becomes Possible on the Veehop 4WD Scooter

Published

on

Veehop 4WD Scooter
The Veehop 4WD Scooter is worth a look for anyone who wants to take a scooter somewhere a standard two wheeler simply could not handle. Four wheels, each with its own electric motor and independent suspension, give it the kind of all terrain capability that the name suggests, and with the stem folded down it is compact and light enough to fit in most car trunks.



Each of the four hub motors produces 750 watts nominally and up to 1,500 watts at peak, combining for a total output of 6 kilowatts and 177 pound feet of torque. Top speed on flat ground sits at 31 mph, and a 50 percent incline is handled without complaint. With power going to each wheel independently, mud, rocks, gravel, and shallow water are all manageable terrain rather than reasons to turn back.

Independent suspension keeps the deck level even when one side drops into a rut, and sturdy plating protects the frame and battery bay from scrapes across rough ground. At 154 pounds it is heavier than a standard scooter, but that weight starts to justify itself the moment the terrain gets interesting. Total load capacity sits at 441 pounds, and an optional saddle lets you ride seated while still controlling the throttle and steering through weight shifts.

The 60 volt battery pulls out in seconds for quick swaps, with a capacity of up to 40 amp hours giving you around 37 miles of range at a steady pace or closer to 25 miles if you are pushing hard. A full charge takes four to five hours with the standard charger, and anyone planning longer sessions can simply carry a spare battery and swap it out as needed.

Veehop 4WD Scooter
The folding stem keeps storage straightforward, sliding into most car trunks without much fuss, though hauling it up a flight of stairs is a workout given the weight. A small handlebar display shows speed, battery level, and a basic ride overview, with a thumb throttle and a few simple buttons handling all the controls. The Veehop 4WD starts at 3,750 dollars for the full four-wheel-drive option, the two-wheel drive model comes in at 3,350 dollars. Both are shipping right now and the company is inviting customers to schedule a test ride. They’ve also got extra batteries and a few other smaller accessories up for sale as well.

Using A Scientific Satellite For Passive Radar

Published

on

The basic principle of radar systems is simple enough: send a radio signal out, and measure the time it takes for a reflection to return. Given the abundant sources of RF signals – television signals, radio stations, cellular carriers, even Wi-Fi – that surround most of us, it’s not even necessary to transmit your own signal. This is the premise of passive radar, which uses passive RF illumination to form an image. The RF signal doesn’t even need to come from a terrestrial source, as [Jean Michel Friedt] demonstrated with a passive radar illuminated by the NISAR radar-imaging satellite (pre-print paper).

NISAR is a synthetic-aperture radar satellite jointly built by NASA and ISRO, and it completes a pass over the world every twelve days. It uses an L-band chirp radar signal, which can be picked up with GNSS antennas. One antenna points up towards the satellite, and has a ground plane blocking the signal from directly reaching the second antenna, which picks up reflections from the landscape under observation. Since the satellite would illuminate the scene for less than a minute, [Jean-Michel] had to predict the moment of peak intensity, and achieved an accuracy of about three seconds.

The signals themselves were recorded with an SDR and a Raspberry Pi. High-end, high-resolution SDRs such as the Ettus B210 gave the best results, but an inexpensive homebuilt MAX2771-based SDR also produced recognizable images. This setup won’t be providing any particularly detailed images, but it did accurately show the contours of the local geography – quite a good result for such a simple setup.

Everything you need to keep your data safe on World Backup Day

Published

on

Tuesday March 31, is World Backup Day. It’s that necessary annual reminder to back up all our important data and documents. And with so many different ways to back up your files, once you’ve set it up, you can leave it unattended, safe in the knowledge that if the worst happens, you’re protected.

Below you’ll find a comprehensive collection of our favorite backup products and methods, including HDDs and SSDs — both internal and external — portable flash drives, SD cards, NAS systems, and software and cloud backup solutions.

Where possible, I’ve tried to hunt down the lowest prices available for each item, focusing on deals and limited-time discounts. Over the course of the week, I’ll be checking regularly to make sure prices stay accurate and all the products are still in stock.

The ongoing memory crunch does mean prices for some items remain higher than usual, particularly SSDs and other flash-based storage, and demand for high-capacity memory and storage continues to grow. Although deals still appear regularly, they don’t usually last long.

How Automakers Are Using Blockchain Tech, And Why It’s So Useful

Published

on





You don’t hear much about blockchain these days. Back in the late 2010s, when everyone was talking about NFTs and cryptocurrency, companies were keen to put “blockchain” front and center on their press releases. “Look at us,” they were saying, “we’re embracing modern technology.” But after the sad evolution of cryptocurrency, brands seemed to decide they didn’t need the baggage that came with the word “blockchain.” But that doesn’t mean it’s gone away — just that companies are likely to call it something different now. You’re just more likely to hear things being referred to as distributed ledgers or “on-chain” tech.

According to the cryptocurrency exchange Coinbase, 60% of Fortune 500 companies are working on blockchain initiatives. The sectors that use blockchain the most are banking and finance, which account for around 20% of its use, but it’s used across all types of business, including the automotive industry.

Before we look at how carmakers use blockchain, it’s useful to understand what exactly blockchain is. At its most basic, blockchain is a shared digital record that isn’t controlled by any single company or authority. Instead, identical copies are stored across a network of computers, and new information is added in secure, time-stamped “blocks” that are linked together. Because each new entry is verified by the network and connected to what came before it, the record is very difficult to alter or tamper with. This immutability makes it useful for automakers who are looking to provide things like digital battery passports and vehicle provenance. However, some car manufacturers are planning to take the tech even further.

Blockchain is useful when it comes to storing digital battery passports. These are electronic records tracking the lifecycle of an EV battery and are going to be required in all countries in the European Union by 2027. This regulation affects all automakers who are selling into Europe — including those headquartered in the United States. Automakers need traceability data, and supply chains are international. A modern electric vehicle battery isn’t a single bill of materials so much as a web of upstream mining, refining, processing, cell manufacturing, pack assembly, recycling, and logistics. A blockchain-powered distributed ledger can serve as one definitive record of permissions and provenance that can be shared by different companies.

In June 2024, Volvo Cars launched what it claimed to be the world’s first EV battery passport for its EX90 SUV. The passport uses blockchain to record information such as the origins of raw materials, recycled content, and carbon footprint. Volvo plans to expand the scheme to more of its cars. Meanwhile, Tesla has implemented blockchain solutions to trace the provenance of cobalt in its supply chains. Hyundai and Kia developed an Integrated Greenhouse Gas Information System (IGIS), using blockchain to record emissions across the whole lifecycle of a vehicle.

Another use for blockchain is providing proof of provenance for collectible cars. Porsche is utilizing its unalterable nature to launch a blockchain-based digital passport pilot for classic cars, as well as other collectibles like watches or paintings. Automakers aren’t the only ones using blockchain for car records. In July 2024, Reuters reported that the California Department of Motor Vehicles had digitized 42 million car titles using blockchain technology to detect fraud and streamline title transfers.

Other uses for blockchain in the automotive industry

One of the main uses of blockchain in the automotive industry is handling companies’ finances. For example, BMW uses a blockchain system from JPMorgan to handle international financial transactions automatically. However, some pilots and plans suggest that there may be more innovative uses in the future. The much-hyped — but still not yet available — Sony/Honda Afeela EV sedan promises an “on-chain mobility service platform leveraging a token-based incentive model.” Details are still pretty fuzzy, but it does indicate another use for blockchain in the automotive industry, even if it is just persuading people to share their data by giving them cryptocurrency. Nissan is proposing something similar with its Nissan Passport, which it describes as a “digital certificate that expands the range of experiences you can access based on your actions.”

Toyota, the world’s largest automaker, is betting big on blockchain tech and has its own “Blockchain Lab” exploring how blockchain could be used to give vehicles a secure digital identity, bundle fleets into investable portfolios, and make it easier to attract funding for things like electric vehicle fleets and new mobility services. It is proposing a new blockchain-based protocol called the Mobility Orchestration Network (MON), which would link vehicles with other agencies, like regulators, on one all-encompassing digital platform. Toyota’s interest in blockchain goes beyond car manufacturing. It created Woven City, a blockchain-integrated smart city, in September 2025. The goal here is to use blockchain as a trusted digital system that lets people safely share vehicles, electricity, and city services without needing middlemen or paperwork.

Hackers now exploit critical F5 BIG-IP flaw in attacks, patch now

Published

on

F5

​Cybersecurity firm F5 Networks has reclassified a BIG-IP APM denial-of-service (DoS) vulnerability as a critical-severity remote code execution (RCE) flaw, warning that attackers are exploiting it to deploy webshells on unpatched devices.

BIG-IP APM (short for Access Policy Manager) is a centralized access management proxy solution that enables admins to secure and manage user access to their organizations’ networks, cloud, applications, and application programming interfaces (APIs).

Tracked CVE-2025-53521, this security flaw can be exploited by attackers without privileges to perform remote code execution when targeting BIG-IP APM systems with access policies configured on a virtual server.

In addition to flagging the vulnerability as being exploited in the wild, F5 published indicators of compromise (IOCs) and advised defenders to check their BIG-IP systems’ disks, logs, and terminal history for signs of malicious activity.

“This known vulnerability was previously categorized and remediated as a Denial-of-Service (DoS) vulnerability. Due to new information obtained in March 2026, the original vulnerability is being re-categorized to an RCE. The original CVE remediation has been validated to address the RCE in the fixed versions. We have learned that this vulnerability has been exploited in the vulnerable BIG-IP versions,” F5 warned in an advisory update published this Sunday.

“F5 strongly recommends that you consult your corporate security policy for guidelines about incident handling procedures including but not limited to forensic best practices, that are specific to your organization. More specifically, review the policies to ensure that they comply with evidence collection and forensics procedures for a security incident before you attempt to recover the system,” the company added.

Internet threat-monitoring non-profit organization Shadowserver now tracks over 240,000 BIG-IP instances exposed online; however, there is no information on how many have a vulnerable configuration or have already been secured against CVE-2025-53521 attacks.

​The U.S. Cybersecurity and Infrastructure Security Agency (CISA) also added the vulnerability to its list of actively exploited flaws on Friday and ordered federal agencies to secure their BIG-IP APM systems by midnight on Monday, March 30.

“This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise,” it warned.

“Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”

In recent years, BIG-IP vulnerabilities have been exploited by nation-state and cybercrime threat groups to breach corporate networks, map internal servers, deploy data-wiping malware, hijack devices, and steal sensitive documents from victims’ networks.

F5 is a Fortune 500 technology giant that provides cybersecurity, application delivery networking (ADN), and various other services to more than 23,000 customers worldwide, including 48 of the Fortune 50 companies.

Starcloud raises $170 million Series Ato build data centers in space

Published

on

Starcloud’s latest funding round values the space compute company at $1.1 billion, making it one of the fastest startups to reach unicorn status after graduating from Y Combinator.

The company’s Series A, which closed 17 months after its demo day presentation, was led by Benchmark and EQT Ventures. It’s another sign of the interest in outsourcing data centers to orbit as resource and political obstacles slow their development on Earth, but the business model depends on unproven technology and significant capital expenditure.

Starcloud has now raised a total of $200 million, and launched its first satellite with an Nvidia H100 GPU in November 2025. The company will launch a more powerful version, Starcloud 2, later this year with multiple GPUs, including an Nvidia Blackwell chip and an AWS server blade, as well as a bitcoin mining computer.

The company will also begin developing a data center spacecraft designed to launch from Starship, the reusable heavy lift rocket being built by Elon Musk’s SpaceX. Starcloud 3, as the spacecraft is named, will be a 200 kilowatts, three-ton spacecraft that fits the “pez dispenser” system SpaceX designed to deploy its Starlink satellites from Starship.

CEO and founder Philip Johnston said he expects that will be the first orbital data center that is cost-competitive with terrestrial data centers, with costs on the order of $.05 per kw/hour of power — if commercial launch costs land around $500 per kilogram.

The challenge is that Starship isn’t flying yet; Johnston says he expects commercial access to open up in 2028 and 2029. That’s the reality facing all the big space data center projects: powerful space computers will be cost-prohibitive until a new generation of rockets starts launching at a high operational cadence, something that might not happen until the 2030s.

“If it ends up being delayed, we’ll just carry on launching the smaller versions on Falcon 9,” Johnston said. “We’re not going to be competitive on energy costs until Starship is flying frequently.”

“There’s kind of two business models,” Johnston explains: One is selling processing power to other spacecraft on orbit; the company’s first satellite, for example, analyzes data collected by Capella Space’s radar spacecraft. Then, in the future when launch costs go down, more powerful distributed data centers could potentially pull work from their terrestrial counterparts.

That gets at how new this industry really is. When Nvidia CEO Jensen Huang unveiled the company’s Vera Rubin Space-1 chip modules at his company’s annual GPU Technology Conference last week, he didn’t note that none had been produced or shared with the company’s development partners. 

In fact, the number of advanced GPUs on orbit is numbered in the dozens, while Nvidia is estimated to have sold nearly 4 million to terrestrial hyperscalers in 2025. 

Or consider that SpaceX’s Starlink communications network, the largest satellite network in orbit with 10,000 spacecraft, produces something around 200 megawatts of energy, while data centers with more than 25 gigawatts of power are currently under construction in the U..S, according to Cushman and Wakefield. 

Johnston argues that his company is well ahead of the competition, with the first terrestrial GPU deployed in orbit. It was used to train an AI model in orbit, a first, according to Starcloud, and run a version of Gemini. Beyond the performance, Johnston says Starcloud now has valuable data about what it takes to run a powerful chip in space.

“An H100 is probably not the best chip for space, to be honest, but the reason we did it is we wanted to prove that we could run state of the art terrestrial chips in space,” he told TechCrunch. That hard-won knowledge —another GPU, an Nvidia A6000, failed during launch — will influence future designs.

There is a laundry list of technical challenges to be solved, including efficient power generation and cooling the hot-running chips. Starcloud-2 will have the largest deployable radiator flown on a private satellite; he expects at least two additional versions of that spacecraft will head to orbit, Johnston said.

Then there is the challenge of synchronization. The largest datacenter workloads, often for training, require hundreds or thousands of GPUs to work in tandem. Doing that in space will either require fantastically large spacecraft, or powerful and reliable laser links between spacecraft flying in formation. Most companies working on this technology expect those workloads to come long after simpler inference tasks take place on orbit.

Besides Starcloud, Aetherflux, Google’s Project Suncatcher, and Aethero — which launched Nvidia’s first space-based Jetson GPU in 2025 — are all developing space data center businesses.

The elephant in the room is SpaceX itself, which has asked the U.S. government for permission to build and operate a million satellites for distributed compute in space.

Going head-to-head with SpaceX is a daunting task for any entrepreneur, but Johnston sees room for coexistence.

“They are building for a slightly different use case than us,” he told TechCrunch. “They’re mainly planning on serving Grok and Tesla workloads. It may be at some point that they offer a third party cloud service, but what I think they are unlikely to do is what we’re doing [as] an energy and infrastructure player.”

The Hazards Of Charging USB-C Equipped Cells In-Situ

Published

on

Can you charge those Li-ion based cells with USB-C charging ports without taking them out of the device? While this would seem to be answered with an unequivocal ‘yes’, recently [Colin] found out that this could easily have destroyed the device they were to be installed in.

After being tasked with finding a better way to keep the electronics of some exercise bikes powered than simply swapping the C cells all the time, [Colin] was led to consider using these Li-ion cells in such a manner. Fortunately, rather than just sticking the whole thing together and calling it a day, he decided to take some measurements to satisfy some burning safety questions.

As it turns out, at least the cells that he tested – with a twin USB-C connector on a single USB-A – have all the negative terminals and USB-C grounds connected. Since the cells are installed in a typical series configuration in the device, this would have made for an interesting outcome. Although you can of course use separate USB-C leads and chargers per cell, it’s still somewhat disconcerting to run it without any kind of electrical isolation.

In this regard the suggestion by some commentators to use NiMHs and trickle-charge these in-situ similar to those garden PV lights might be one of the least crazy solutions.
