If you’ve ever submitted a support ticket to LastPass, that exchange may now be in the hands of hackers. According to TechCrunch, the password manager has confirmed that customer names, contact details, and support case records were exposed in a recent breach at one of its third-party vendors.

What the hackers got, and what they didn’t

LastPass said its own systems were not compromised and that users’ password vaults remain secure. The exposed data was instead accessed through Klue, a market research company LastPass works with.

While no passwords were stolen, the hackers used their access to Klue’s network to pull customer records, including phone numbers, email addresses, physical addresses, and contents of support tickets.

In a blog post about the incident, the company stressed that the breach did not affect encrypted password vaults, master passwords, or any credentials stored within LastPass itself. Even so, the exposed information could still prove useful to attackers, who could leverage it for phishing or social engineering campaigns.

A years-old credential opened the door

The LastPass exposure stems from a wider security breach at Klue, which revealed that attackers gained access using a credential linked to a pilot project dating back to 2022. TechCrunch reports that the credential remained active and provided a way into the company’s systems.

Klue said the attackers were able to access customer data connected to its services, affecting multiple organizations that relied on the platform. Along with LastPass, Gong, Jamf, HackerOne, Insurity, OneTrust, Recorded Future, Snyk, Huntress, Sprout Social, and Tanium were affected.

For LastPass, this marks the second time its users have had data caught up in a breach. A 2022 breach exposed encrypted password vaults that were later linked to cryptocurrency theft. This latest exposure did not involve vault data or passwords, but it highlights how a security lapse at a third-party vendor can still affect customers who never interacted with the vendor directly.

OFFBEAT

A time when Windows 7 was Microsoft’s latest and greatest

BORK!BORK!BORK! A blast from the past greets customers at a coastal McDonald’s, or is it just that the kiosk is seeking a return to the happier and simpler times of 2009?

An eagle-eyed Register reader spotted a very unhappy terminal at a branch of the McDonald’s fast-food chain in Worthing, England. Where a customer might normally smear a finger over suggestions for ways to sate their desire for grease, the display instead reveals the kiosk’s clearly PC origins: a BIOS utility.

It’s not clear what has befallen the kiosk, though something has happened to the hardware that has sent it to the utility screen, which is normally accessible by holding down a key or combination of keys during the boot process. Although the BIOS is dated 2016, the system date is currently set to 2009.

Worthing is a town on the south coast of England, occasionally unfairly and unkindly referred to as “God’s waiting room” due to the large retiree population it once had. While the town has long since shed that sobriquet (although it still lacks the hip and trendy traits of neighboring Brighton), it seems that there is one place that would very much like to turn back the clock.

McDonald’s.

Cast your mind back to 2009. Bitcoin was launched, an Airbus A320 ditched onto the Hudson River with no fatalities, and US President Barack Obama was sworn in.

Best not to think about how much a Bitcoin acquired then might be worth now.

2009 was also the year Microsoft released Windows 7, the successor to Windows Vista and the precursor to the widely derided Windows 8. Microsoft might not have realized it at the time, but this was arguably peak Windows. Sure, Windows 95 was arguably more of a cultural “moment,” and XP was an undeniable milestone, but 7 reached heights Microsoft has not matched since.

2009 was also a few years before McDonald’s began rolling out touchscreen kiosks to replace the experience of peering over the shoulder of the person behind the counter to see which foodstuffs were ready to go.

Today, the person behind the counter is far less visible, obscured by a line of delivery riders collecting app orders. The BIOS utility screen, however, looks back to an earlier time.

Or, possibly, Worthing is simply 17 years behind the rest of the world. ®

Displays for the iPhone Fold and touchscreen MacBook Pro will come from Samsung, while LG will make screens for the Apple Watch Series 12, says a repeat rumor.

Apple’s first foldable iPhone is slated to debut in 2026. While it will mark Apple’s entry into new smartphone territory, its displays will seemingly be produced by a tried-and-true Apple supply chain partner.

On Tuesday, mere days after the claim of Samsung OLED panels on the iPhone Fold was repeated, yet another report said the same thing. As 9to5mac points out, ET News says OLED screens for the iPhone Fold, iPad mini, and touchscreen MacBook Pro will be provided exclusively by Samsung Display.

Supposedly, Samsung Display is set to produce 10 million OLED panels for the iPhone Fold and 2 million for a future iPad mini. The publication claims the production of iPhone 18 Pro, iPhone 18 Pro Max, and iPad mini displays has already begun, with the production of iPhone Fold display hardware expected to follow.

As for the long-rumored OLED MacBook Pro, Tuesday’s report says that panel production will begin in July 2026, once Samsung Display’s 8.6th-generation OLED line becomes operational.

Repeat rumors dating back to 2024

As far back as April 2025, it was reported that the iPhone Fold would feature a Samsung-made OLED panel. In September 2025, the president of Samsung Display said that the company would provide foldable OLED displays to a North American client, presumably Apple.

As with the iPhone Fold, rumors of Samsung-made OLED panels for the MacBook Pro go back to at least September 2025. Claims of Samsung making an OLED iPad mini display for 2026 go back even further, to May 2024.

In that regard, Tuesday’s display-related report is arguably nothing more than a “me too” rumor, with no significant new information.

Even when discussing LG Display’s role in the Apple supply chain, the report only backs up earlier rumors. On June 2, 2026, it was said that LG Display would produce screens for the Apple Watch Series 12. Tuesday’s rumor reiterates that claim, adding that 34 million panels will be made for the device.

Chinese supplier BOE, meanwhile, won’t produce any displays for the iPhone Fold, OLED MacBook Pro, iPhone 18 Pro, or iPhone 18 Pro Max. Again, this is something that was already said in May 2026.

Overall, the display-focused report published on Tuesday doesn’t reveal much of anything. It reiterates claims others have already made and states the obvious.

It’s an odd-seeming move for a company selling an AI writing assistant.

Unexplained GSM-R failure at Deutsche Bahn caused confusion and delay

Train services are resuming across Germany this morning, after rail operator Deutsche Bahn (DB) last night shut down operations after its wireless network failed.

At 10:30 PM local time on Tuesday night, DB advised that its GSM-R network was down, meaning all trains had to be held at stations. We understand that even suburban trains ground to a halt.

GSM-R is a version of the 2G GSM standard tuned to the needs of rail operators, who use it to power private networks that carry information necessary to keep their services rolling. The tech is considered obsolete and DB knows it because the company has already signed with Nokia for a 5G replacement that will use the Future Railway Mobile Communication System (FRMCS) – a move also under consideration in the UK.

For now, however, DB needs its GSM-R to connect drivers with signalling services – so three minutes after midnight on Wednesday morning the carrier promised to issue taxi and hotel vouchers to passengers.

At that time, DB also said it had found the cause of the outage and was working to fix it. The company’s techies moved quickly as the network came back online at 00:50.

As of 6:30 AM, however, DB warned “some isolated disruptions may still occur” and advised passengers they’ll need to check that their connections will run on time.

There’s no indication the incident was the result of a cyberattack and The Register can find no reference to cut cables or other physical layer incidents that could have caused a nationwide outage.

Whatever went wrong isn’t a good look as any network powering critical infrastructure is supposed to have layers of redundancy to ensure resilience.

At least the org made heroes of its tech team.

“Our IT experts worked tirelessly to resolve the issue – successfully,” reads a company statement. ®

​​Microsoft has released the KB5095093 preview cumulative update for Windows 11 24H2 and 25H2, which fixes numerous bugs and begins rolling out new features, including the new Point-in-Time restore feature.

The KB5095093 update is part of the company’s optional non-security preview update schedule, which releases updates at the end of each month to test new fixes and features coming in next month’s Patch Tuesday.

Unlike regular Patch Tuesday cumulative updates, monthly non-security preview updates do not include security updates and are optional.

You can install the KB5095093 update by opening Settings, clicking on Windows Update, and then “Check for Updates.”

Because this is an optional update, you will be asked if you want to install it by clicking the “Download and install” link unless you have the “Get the latest updates as soon as they’re they’re available” option enabled, which will cause the update to automatically install.

You can also manually download and install the KB5095093 preview update from the Microsoft Update Catalog.

Windows 11 KB5095093 highlights

Once installed, this optional cumulative release will update Windows 11 24H2 systems to build 26100.8737 and Windows 11 25H2 to 26100.8737.

This update introduces numerous new features, including a standout Point-in-Time Restore feature that allows Windows users to easily roll back their operating system, applications, and files to a previous point in time.

“Point-in-time restore enables users to restore a Windows PC to the exact state in which it was at an earlier point in time. It happens in minutes using restore points.” explains Microsoft.

“Restore points are stored locally on the device and are captured using Volume Shadow Copy Service (VSS). Point-in-time restore helps recover faster from issues by restoring the full system state captured within the last 72 hours. This feature is designed to help minimize downtime and simplify remediation, without the need for technical ability or lengthy troubleshooting.”

For consumers, new restore points are created every 24 hours and are deleted after 72 hours or when your system runs out of allocated storage space. Those on enterprise licenses can configure Point-in-time restore snapshots to occur at 4, 6, 12, 16, and 24 hours and to be retained with the same intervals.

The settings also allow you to increase the storage space allocated to this system, allowing you to create more frequent snapshots without risk of them being deleted due to a lack of storage.

While you may think this feature is the same as System Restore, Microsoft says point-in-time restore focuses on “reliability and a broad range of issues,” sharing the following table to illustrate the differences between the two features.

This update also fixes a known bug that displayed internal file names instead of the normal filename in confirmation dialogs when deleting a file from the Recycle Bin.

“This update addresses an issue where the confirmation dialog might display an internal Recycle Bin file name instead of the original file name when permanently deleting a file. This issue might occur after installing the June 2026 security update,” explains Microsoft.

A three wheeled roadster in supercar clothing recently crossed the auction block and turned plenty of heads along the way. From a distance the sharp creases and menacing front end easily pass for a Lamborghini Aventador in full flight. Move in closer and the proportions shift. A single large rear tire sits centered under an otherwise familiar open air cabin while Polaris script still marks the sides.

Polaris set out to build the Slingshot R, a motorcycle that has the power of a high-performance sports car but without the fuss. The developers behind this project chose a 2-liter inline four cylinder engine that likes to rev, up to 8,500 RPM in fact, and produces a robust 203 horsepower and 144 pound feet of torque. This raw power is transmitted to the rear wheels via a five-speed automatic manual gearbox and a seriously sturdy belt drive. All of this is supported by a seriously low curb weight of approximately 1,650 pounds, which is due to the simple design and the lack of a roof or doors. According to the manufacturer spec sheet, all of this results in a 0-60 mph time of around 4.9 seconds.

The 2023 version of this model experienced a full visual transformation, while the machine’s core remained intact. You still have that wicked low center of gravity and wide front track, which combine to make the thing dart about like a go kart. The lateral grip values are very outstanding, reaching 1.02 g during testing. All of this is sent directly through the belt final drive, while the automatic manual gearbox changes using the wonderful hydraulic actuation. If you’re sitting behind the wheel and pedals, you could be forgiven for believing you’re in a real sports car, but at the end of the day, this thing seems like a heavy bike.

A lot of custom work was done on the front of the item to make it look more aggressive. Some very capable tuners added a fiberglass fender modeled like the Aventador, a reprofiled hood and headlight surrounds, and this amazing radioactive green paint that complements the rest of the bodywork. Then there’s this massive wing hanging over the roll cage. Larger tires were also added, 20 inches in the front and 22 inches in the rear. The interior has been upgraded with new leather and suede, as well as amazing lime green stitching and inlays to complement the outside hue.

The team that worked on the body kit also replaced the wheels and modified the inside to reflect the new appearance. Stock Slingshot Rs are already aggressive, but with the fiberglass and paint, this thing is just dramatic. Not to mention, it sparks conversations wherever it goes. However, the mechanicals have mostly remained unchanged, using the same old three-wheeled design.

A few weeks ago, someone offered this custom project on Cars & Bids, and bidding reached a high of $13,786 before falling short of the reserve price. Clean, low-mileage Slingshot Rs are commonly priced between the mid teens and mid twenties. So, take your pick: this is either a daring or strange style choice. Whether this custom kit works depends on how you appreciate your motorcycles; is it a good idea to mix American motorcycle technology with Italian exotic styling cues?

Anthropic is launching Claude Tag in research preview, an “always-on Claude” that lives inside Slack and acts as a persistent AI teammate. The feature lets users tag @Claude to get insights in conversations and assign tasks. It is available to Claude Enterprise and Claude Team customers starting today.

Claude Tag is an evolution of Anthropic’s existing Slack integrations, which already let users direct-message Claude or tag it in channels for on-demand help. Claude Code in Slack can also route coding tasks from channel mentions to full coding sessions on the web, posting updates back into the thread. But Claude Tag adds a layer of persistent context and memory that the previous tools could not maintain.

“As Claude follows along with its channel, it learns ever more about the work,” Anthropic said in a statement. Claude can also automatically gather facts from elsewhere in the organisation if granted permission to read other channels. The result is an AI that accumulates institutional knowledge over time rather than starting from scratch with every interaction.

The 💜 of EU tech

The latest rumblings from the EU tech scene, a story from our wise ol’ founder Boris, and some questionable AI art. It’s free, every week, in your inbox. Sign up now!

Everyone in a given Slack channel can access a single Claude identity, meaning anyone can see what Claude has been working on and pick up the conversation from where the last person left off. System administrators specify which tools, information, and channels each Claude identity can access, and each identity stays scoped to whichever channels the admins define. A Claude set up for legal work cannot seed memories into the engineering channel, for example.

When assigned a task, Claude Tag breaks it into stages and works through them using whichever tools it has access to, responding in a Slack thread with what it has created. But the more notable feature is an ambient mode that proactively jumps into conversations to keep teams updated, flag relevant information from across the organisation, and follow up on threads or tasks that have been forgotten.

The ambient mode is the feature that separates Claude Tag from a conventional chatbot. Rather than waiting to be asked, Claude monitors the channels it has been assigned to and intervenes when it judges that a team would benefit from a reminder, a summary, or a piece of context pulled from another part of the company. Anthropic says this makes it feel like “working with a real colleague, one that can produce work in public view, with far greater context and understanding than before”

Organisational context is increasingly the battleground for enterprise AI. Microsoft has been building Work IQ, an intelligence layer expressed through Copilot that draws on Microsoft Graph to understand roles, collaboration patterns, and organisational structure. Startups like Viktor have raised tens of millions to put AI coworkers directly inside Slack and Teams.

Glean, which recently surpassed $300 million in annual recurring revenue at a $7 billion valuation, is building a permissions-aware knowledge graph that sits between the model and enterprise data.

Claude Tag is Anthropic’s answer to the same problem, but its approach is narrower and arguably more disciplined. Rather than building a horizontal intelligence layer across every enterprise application, it plants the AI inside the one surface where most knowledge work already happens: the team chat. The bet is that persistent presence in Slack, combined with cross-channel memory and admin-controlled scoping, is enough to accumulate the institutional context that makes an AI agent useful.

The privacy implications are substantial. An always-on AI that follows along with workplace conversations and autonomously decides when to intervene will face scrutiny from both employees and compliance teams. Anthropic’s admin-scoping controls are the structural answer to that concern, but the real test will come when enterprise customers deploy it at scale and discover how workers respond to an AI that is always listening.

Anthropic says it is working to bring Claude Tag to other platforms in the coming weeks. For now, Slack is the only surface, which limits the feature’s reach but also constrains its complexity, a deliberate trade-off for a research preview.

Use of Arm cores and Linux mean Beijing hasn’t broken away from the world

The TOP500 list of Earth’s mightiest supercomputers has a new leader: the 2.198 Exaflop/s LineShine machine housed at the National Supercomputer Center (NSC) in Shenzhen, which took the top spot without using any kit from Nvidia, Intel, or AMD.

Which is not to say that LineShine is an entirely Chinese creation. As explained in a pre-press paper, the machine’s LX2 processors are a local effort but use Armv9 designs – so chalk up a win for Blighty, the home of Arm. The machine also runs KylinOS – a Linux distribution that features contributions from around the world.

The paper reveals that LineShine comprises 20,480 computing nodes, and that each LX2 processor “integrates two compute dies (304 cores total) and eight on-package HBM stacks (32 GB, 4 TB/s aggregate bandwidth).”

“Each compute die contains 152 cores and 128 GB of off-package DDR memory organized into four NUMA domains,” the paper adds. “A dedicated SDMA engine handles data movement between DDR and HBM. The LX2 supports FP64/FP32/FP16/INT8 via SME and SVE units, delivering up to 60.3/120.6 TFLOPS in FP64/FP32. Nodes are interconnected via the LingQi high-speed network with a dual-plane multi-rail fat-tree topology, offering 1.6 Tb/s bandwidth per node.”

That network is also a Chinese creation, from the minds at Hangzhou LingQi Technology Co.

LineShine became the first system on the TOP500 to exceed two exaflops of sustained double-precision performance using CPUs only and the curators of the list think it could do better in future tests, because this time around it reached about 80 percent of its 2.736 Exaflop/s theoretical peak in tests conducted in preparation for this iteration of the TOP500 list.

News that LineShine topped the supercomputing charts comes as China’s government increasingly steers local organizations towards buying made-in-China tech. Beijing wants to decrease dependency on foreign products, because China has gone all-in on AI and other technologies to boost economic growth and enhance the capabilities of its military.

China’s Communist Party understands that reliance on imports can stymie those ambitions, with the USA’s ban on GPU sales to the Middle Kingdom offering ample evidence of the need to control tech supply chains. And now Beijing can point to its policies producing the most powerful single computer on the planet.

It’s conceivable that China could do even better in the future, as its GPU industry is nascent and currently producing products whose performance trails Nvidia and AMD by four or five years.

Those two paragons of US computing power, along with Intel, dominate this version of the TOP500 list – as has been the case for years. China is therefore on the march, but is a long way from global dominance.
