The government's push to "mainline AI into the veins" of the nation marks a transformative era. However, the very foundation of this progress - the energy grid - has become a lucrative target for malicious actors. AI-driven technologies promise greater efficiency and resilience, yet their dependence on the UK’s energy sector puts a bigger target on the country’s critical infrastructure. As the UK advances toward making its mark as a global AI leader, its energy sector faces a critical challenge of the rising threat of cyberattacks.

With national security and technological leadership at stake, energy providers must urgently fortify their defenses to safeguard the UK's AI ambitions from disruption.

The growing cyber threat against legacy systems

According to Trustwave’s latest report, the average cost of a data breach in the energy sector stands at a staggering $5.29 million, significantly exceeding the cross-industry average of $4.8 million. The financial toll is just the tip of the iceberg; a successful cyber-attack against the UK’s energy sector could lead to far more severe consequences such as operational disruptions, national security risks, and a loss of public trust. Given the centrality of the energy sector to AI-powered progress, any interference could derail the UK's momentum towards technological leadership.

One of the more significant challenges is the sector's reliance on ageing infrastructure and legacy systems. Thames Water highlighted in 2024 that some IT systems date back to the 1980s, leaving them highly vulnerable. Outdated systems also hinder compatibility with modern security solutions, essential for protecting against cyber threats without disrupting operations.

Moreover, the sector is integrating its physical infrastructure with digital systems like Supervisory Control and Data Acquisition (SCADA) and IoT. While this enhances efficiency, increasing digital transformation also expands the risk of cyberattacks. This integration exposes vulnerabilities and complicates securing both operational technology (OT) and IT infrastructures. Securing OT systems requires specialized cybersecurity approaches due to their proprietary nature and direct impact on physical infrastructure. Balancing security with operational reliability is crucial, as using traditional IT security methods could leave energy organizations on the back foot.

Finally, energy companies face significant challenges in overhauling aging infrastructure due to costs and operational risks. Connecting legacy systems to modern networks or IoT devices could pose further security risks without appropriate and proactive cyber hygiene measures. Protecting these systems while transitioning to more secure technologies demands strategic planning, investment, and collaboration between IT and OT teams.

Ransomware on the horizon

When it comes to cybersecurity, IT or OT infrastructure is unfortunately not the only concern that the energy and utility sector needs to be aware of. Especially since the UK’s ambition for AI leadership has further raised the critical importance of the energy and utilities sector in the UK, it has become that much more of a lucrative target for cybercriminals and nation-state hackers to disrupt essential services and cause further financial, economic and community damage.

There has been a significant increase in ransomware attacks targeting the energy and utilities sector, with an 80% year-over-year increase globally. The number of attacks was notably higher in the second half of 2023 and the first half of 2024. This increase in the number of ransomware attacks can be linked to the rise in Ransomware-as-a Service (RaaS) groups, which has enabled less-skilled attackers to carry out highly-sophisticated ransomware campaigns. Additionally, as ransomware groups refine their tactics, they become more effective at exploiting weak links within the sector, increasing the chances of widespread disruption and financial loss.

A pressing concern is the sector's supply chain weaknesses. Ransomware groups frequently target suppliers and service providers, who often have privileged access to critical systems but lack the same level of security controls as energy companies themselves. A single compromised supplier can serve as an entry point, allowing attackers to infiltrate multiple clients and escalate their impact across the industry.

Compounding this challenge is a fundamental lack of visibility within energy organizations. Many struggle to maintain an accurate inventory of their assets, track their access levels, and understand interconnections between systems. This opacity leads to security blind spots, making it easier for ransomware groups to exploit overlooked vulnerabilities and move laterally within networks undetected.

Remote services further expand the attack surface, providing cybercriminals with a pathway into critical systems. Attackers frequently exploit remote access tools such as SMB/Windows Admin Shares and Remote Desktop Protocol (RDP) to gain persistence within a network. Without stringent access controls and monitoring, these services can serve as a gateway for ransomware deployment and data exfiltration.

Building cyber resilience in the energy sector

Addressing the challenge of legacy systems in the energy and utilities sector, many of which were not designed to withstand modern cyber threats, requires energy companies to implement virtual patching for unpatched systems, strict access controls, and network segmentation to isolate vulnerable assets. A phased approach to infrastructure modernization, coupled with secure OT-IT integration is an additional critical requirement as this allows energy companies to upgrade systems while maintaining operational stability.

Zero-trust security frameworks need to be established as these require continuous verification of all users and devices. Such a framework further reduces risks associated with interconnected IT and OT environments. Furthermore, investing in specialized OT cybersecurity measures, including intrusion detection systems (IDS) tailored to industrial environments, ensures that security efforts do not disrupt critical operations.

Operational stability and resilience is, of course, especially critical for energy and utilities providers given the profound impact to businesses and communities that an operational halt could have. For instance, our research report found that an attack on one such facility that houses 400 million cubic meters of gas, could leave London (8.87 million people) without gas for over two weeks (14.6 days).

Energy and utility providers must begin to prioritize bolstering resilience through the use of proactive threat intelligence, dark web monitoring, and incident response planning to prepare for and respond to emerging threats. Strengthening supply chain security, enforcing multi-factor authentication (MFA), and ensuring regulatory compliance are supplementary steps in a robust defense against cyber adversaries.

The path forward

Ultimately, as the UK pushes forward with its AI ambitions, the energy sector must remain vigilant against the escalating cyber threats that could hinder this progress. AI’s transformative potential hinges on a stable and secure energy infrastructure—without it, the nation's leadership in AI and digital innovation is cut off at its knees.

By prioritizing modernized security frameworks, proactive threat intelligence, and comprehensive incident response planning, the UK can safeguard its critical infrastructure from cybercriminals seeking to exploit its digital evolution. A secure energy sector is not just an operational necessity; it is the backbone of the country’s AI-driven future. Only through decisive action and strategic investment in cybersecurity can the UK ensure that its pursuit of technological leadership remains uninterrupted.

• US digital transformation maturity is below the global average
• Workers don’t have the right tools or training
• Basic security measures are missing

Despite world-class investments in AI and other tech, US businesses are lagging when it comes to digital transformation, new research has claimed.

A report from Zoho found as many as two in five (39%) US organizations are still only in the early stages of transformation, with the whole country ranking 1.2 percentage points beneath the global average in terms of transformation maturity.

The slow progress is being blamed on security weaknesses and delayed tool adoption, with only 15% of workers feeling that workplace tools meet their expectations - with separate WalkMe research finding only 28% of employees feel adequately trained.

US digital transformation is lagging

Zoho noted progressing from Level 2 (standardization) to Level 3 (structured operations) could take between three and five years, coming at the cost of $250-500 per employee annually. Reaching Level 4 (optimized digital operations) requires around twice the resources – 10 or more years and $500-1,000 per employee each year.

The majority of companies (85%) are still said to be relying on manual task delegation over automation, with the likes of hospitality, logistics and retail struggling more than their tech-adept counterparts in IT and finance industries. SMBs also lag behind larger firms, likely due to more limited resources - and WalkMe’s research backs this up, uncovering that only one in four use AI to improve efficiency.

Some of the problems highlighted include poor implementation of multi-factor authentication (MFA) (used by just half of the companies analysed), the provision of secure access policies like VPN (available to just one in four) and limited physical security controls (adopted by fewer than one in three).

To put a price on the losses, WalkMe estimates $104 million in losses throughout 2024 due to underutilized technology, as well as 36 days wasted each year by inefficient workers. On the flip side, proper digital adoption could nearly triple returns on transformation investments.

“US businesses have strong foundations in collaboration and digital tools, but security and process inefficiencies are major barriers to transformation," noted Zoho Chief Evangelist Raju Vegesna.

I got the Green group – MESS OF HAIR – easily enough, but then my problems began. I was convinced that there was a group made up of Donald Duck family members – SCROOGE (Donald’s wealthy Scottish Uncle), DEWY his nephew, and DAISY his girlfriend. Rather than think I could be wrong I foolishly plugged away looking for the fourth member of the extended Duck world before the dreaded "Next Time".

HOKA Cielo X1 2.0: two-minute review

(Image credit: Future)

When I got the chance to try the HOKA Cielo X1 2.0, I was ecstatic. It looked plush and had a rocker design, known to alleviate pain and stress in feet and ankles. This sounded like a shoe I needed to test: two years ago, I was dealing with constant pain in my toes, upper foot, and hips when I ran, so often that I had to stop running for weeks at a time. Finally, I found the HOKA Stinson 7, a trail running shoe that was plusher and relieved my pain when nothing else (stretching, doctor visits, etc.) would. That said, most of the time I run on the road, and that trail running shoe was heavier and bulkier than I liked. HOKA may have started out with a trail running shoe, but since then, they’ve been putting out impressive road running shoes year after year and regularly feature in our best running shoes roundup. The HOKA Cielo X1 2.0 launched in February 2025, the second iteration of the Cielo X1 which launched a year before in February 2024. The Cielo X1 2.0 has a more breathable upper made of engineered jacquard mesh – so breathable and clear that I could see my socked toes and feel the wind and some light rain when I ran on a drizzly day.

HOKA also enhanced the forefoot cushioning and improved the outsole traction. During my testing period, it was particularly rainy in Texas and so I had to run on light rain days or after the rain had stopped. I always felt secure and never slipped, not even when I had to run over slick brick roads in my city’s historic downtown.

(Image credit: Future)

The biggest improvement to the Cielo X1 2.0 has to be in the weight and more aggressive rocker profile. Where the Cielo X1 is 9.3 ounces, the Cielo X1 2.0 has dropped to 8.10 ounces. For those who race, an extra 1.2 ounces can go a long way. To achieve the weight reduction, HOKA utilized significant cutouts on the bottom of the shoe.

Perhaps the most noticeable change is the more pronounced rocker design. Running shoes used to be flat with a slight uptilt near the toe, but rocker shoes changed the game when they came on the scene. They get their name from the pronounced curve on the underside of the shoe, which looks like a rocking chair base. The idea behind the design is that once the runner’s foot hits the ground, they’ll naturally and effortlessly rock forward, resulting in more speed. They’re not only designed to make you run faster and without your feet or legs having to do much work, but rocker shoes may alleviate toe, forefoot, and Achilles heel pain, and reduce stress on your ankles and calves.

I had never tried a rocker shoe before, so I felt like a newborn wobbly colt the first time I stood while wearing the Hoka Cielo X1 2.0. That wobbly feeling disappears when you start to run in the shoes.

I initially found the shoe to be springy and quite plush. HOKA notes that this shoe has a “low profile cushion bed that keeps your foot closer to the ground,” but I have to disagree. It doesn’t feel low profile, especially considering that the thickest part of the footbed is two inches; this shoe is lower in profile compared to HOKA’s other – notoriously – thick shoes.

My feet are not narrow by any means but they’re not quite ‘wide-wide’ either. I was able to comfortably run in these shoes, but I can see the toebox being a problem for wide-footed runners who might feel more comfortable with more space.

From the very first run, I really enjoyed the HOKA Cielo X1 2.0. The instability I felt when I first put them on almost immediately disappeared when I started to run. Right away, I felt stable and confident, and I noticed that I was moving faster than normal but without the usual strain or heavy weight of my previous running shoes. I didn’t have to put much effort into running faster, because my ankle and foot worked seamlessly with the rocker profile to propel me forward. There’s a bounce and springiness to the shoe that felt nice on my stride.

(Image credit: Future)

To be fair, my ankles felt a bit shaky during the first few runs. I think this had to do with the cutouts on the bottom of the shoe and how I naturally pronate with one foot and supinate with the other. I’ve rolled my ankles so many times in my life that I’ve lost count, so I don’t have the strongest ankles to begin with, but because the cutouts near the arch are prominent, I could feel my ankles trying to prevent my foot from pronating too much and the other from supinating. It was awkward at first, but after each run, I noticed that my ankles felt stronger, and my feet were pronating and supinating far less than before.

The way I ran also shifted during testing. I realized that with my previous running shoe, I had been effectively “clomping,” and striking with my midfoot and forefoot as I ran. With the HOKA Cielo X1 2.0, more often than not, I struck with my heel or midfoot and then rocked forward on my toes. This new running style felt more natural and resulted in less strain on my feet and legs. If you naturally strike with your forefoot, you can absolutely run in these shoes, but I think you might be missing out on the benefits of the rocker design.

This is definitely a shoe for long-distance runners who run a variety of distances (especially those training for marathons), as it offers a low-effort and speedy running experience. Sure, there may be an adjustment period with the HOKA Cielo X1 2.0, but it’s well worth it in the long run (pun not intended).

HOKA Cielo X1 2.0: price & availability

(Image credit: Future)

• $275/£250/AU$399
• Available in Frost/Black

The Hoka Cielo X1 2.0 is not cheap by any means. At $275/£250/AU$399, they’re on the pricier end for rocker running shoes, though this isn’t surprising for a brand like HOKA that aims to provide the best type of running shoe for marathon runners. Currently, the Cielo X1 2.0 is only available in a single color option – Frost/Black – and is sold through HOKA and running stores like Road Runner Sports, Marathon Sports, and Paragon Sports. HOKA offers free delivery and free 30-day returns.

HOKA Cielo X1 2.0: specifications HOKA Cielo X1 2.0: scorecard Should I buy the HOKA Cielo X1 2.0?

(Image credit: Future) Buy if it...

You’re a road racer looking for speed.

Combine the lightweight nature of the shoe with the rocker design, and you’ll notice an increase in your running speed.

You prefer a super cushioned running shoe.

HOKA notes that the Cielo X1 2.0 has a low profile (maybe in comparison to their other shoes), but at its thickest point, the cushion bed is two inches thick. During a run, your joints will benefit from the thicker sole, just ask the science.

You suffer from plantar heel, toe, and Achilles pain or ankle and calf injuries.

Studies have found that rocker running shoes can decrease the load on ankles, feet, and calves, minimizing a host of pains or injuries. View Deal

Don't buy it if...

You have no interest in adjusting your run

There is a bit of a learning curve to running with the Cielo X1 2.0, and because of its considerable rocker design, it could adjust the way you run.

You’re looking for a multi-purpose running and workout shoe

Due to the prominent rocker design, it’s only suitable for roads and paved trails. It would feel awkward to lift weights or go to the store in these shoes.

You’re on a budget

The HOKA Cielo X1 2.0 is $275. Unless you consistently run or are training for a marathon, you could find a great pair of running shoes at a more affordable price. View Deal

How I tested

I tested the Cielo X1 2.0 over the course of a week and a half, by running a variety of distances on the road, paved trails, and on an indoor track. During the testing period, I was able to gauge the shoe’s effectiveness in various weather conditions – sunny, dry days, and during light rain – and how well they did in terms of comfort and foot and joint relief. Everything from the shoe’s weight to the materials and design were considered during testing.

First reviewed: February 2025

• Lenovo has revealed the Yoga Solar PC over at MWC 2025
• The rear lid of the laptop has a highly efficient solar panel built-in, one that can charge the battery even in low-light
• A bunch of other notebooks have been shown off including more Yoga models and an IdeaPad

Lenovo has revealed a cluster of new laptops over at MWC 2025 including a prototype of a Yoga solar-powered notebook, alongside a number of other Yoga models, and a new take on an IdeaPad.

What’s grabbing the most attention at the show, though, is that Yoga Solar PC which as noted remains a concept piece of hardware, so this isn’t something that’s coming through for production (at least not yet).

The laptop has a solar panel built into the lid that uses ‘Back Contact Cell’ technology, Lenovo explains, to get a high conversion rate from the solar cells. The company claims a 24% conversion rate from the solar energy absorbed by the panel, which is towards the upper end of the efficiency scale in the solar industry right now (at least in real-world usage).

(Image credit: Lenovo)

Lenovo notes the laptop uses a ‘Dynamic Solar Tracking’ system which constantly monitors the solar panel’s current and voltage and “works with the Solar-First Energy system to automatically adjust the charger’s settings to prioritize sending the harvested energy to the system.”

In other words, you get the most bang for buck from the sun’s rays, and the panel is capable of picking up solar energy even in low-light conditions, Lenovo observes. So, when outside even on a dull and cloudy day, the theory is that the Yoga Solar PC will be able to keep its battery charge from depleting – at least while the laptop is idling, anyway.

We only get one concrete figure regarding the kind of solar power that might be on tap here, which is that the panel can “absorb and convert enough direct sunlight in 20 minutes to power up to one hour of video playback on the PC.”

Another notable plus point with the Yoga Solar PC is that this is a thin-and-light device, despite the inclusion of that solar panel, measuring 15mm and weighing in at 1.22kg – impressive.

Lenovo is making a further play on the renewables front with the Solar Power Kit for Yoga, another proof of concept which is basically a power bank that has a detachable USB-C solar panel. That panel can be attached to your backpack, or tent, when out in the wilds, picking up solar power to change the bank’s battery and power your devices.

It's still early days for these concepts, of course, but here’s hoping that one day, a solar-powered portable will be on our list of the best laptops – I don’t see why this won’t happen, it’s just a question of time.

Also at MWC 2025, Lenovo revealed its Yoga Pro 9i Aura Edition offering a 16-inch OLED display with a 3.2K resolution, and tandem OLED tech enabling a high level of brightness (1600 nits) while maintaining power efficiency.

It’s a highly color-accurate (‘PureSight Pro’) screen offering a 120Hz refresh rate, and you can equip the Yoga Pro with up to an Nvidia GeForce RTX 5070 GPU. The CPU is up to an Intel Core Ultra 9 285H, so this can be specified as a very powerful laptop for creative types.

There’ll also be a Lenovo Yoga Pro 7i Aura Edition which comes in a 14-inch rather than 16-inch form factor, alongside a refreshed Yoga Pro 7 14-inch model.

Lenovo had other Yoga models on display, including the Yoga Slim 7 14-inch laptop, another portable aimed at creators with a 2.8K resolution OLED display (and up to 22.5 hours of battery life).

Lenovo Yoga 7 2-in-1 hybrids were also shown off in both 16-inch and 14-inch flavors of these 360-degree convertibles. For more details on all of these Yoga models, check out TechRadar Pro’s coverage here.

Those looking for more of an everyday laptop will be interested to learn about the Lenovo IdeaPad Slim 3x, a 15-inch notebook which carries the tagline ‘AI for anybody.’

This one is a Copilot+ PC with a Snapdragon X (Arm-based) processor partnered with a 60Whr battery for plenty of longevity away from a power socket, and a rapid charge feature that only takes 15 minutes to give you two hours of battery power. That kind of swiftness is always welcome in a pinch when you’re about to leave the house and realize that your notebook is running low on battery.

Other notable attributes of the IdeaPad Slim 3x include a metal cover and durability rated to a MIL-STD-810H standard, and there’s the possibility of future expansion by adding a second SSD via a free slot. It’s always good to see upgrade options with notebooks, as this is another (indirectly) green-friendly option to keep the device relevant and usable going forward in the future.

In Europe, most of these new laptops will emerge later this month, in March 2025, although the exceptions are the Yoga Pro 7 which isn’t coming until April, and the Yoga Pro 9i Aura Edition which won’t arrive until June 2025. However, the US release schedule is quite different to the European release dates.

In the US, some of these laptops aren’t yet marked as available or inbound at all. We know some devices are coming, though, and that includes the Yoga 7 2-in-1 models, with the 14-inch notebook debuting in March 2025 at $899, and the 16-inch model is priced starting from $849 and will be out in Q3 2025.

The Yoga Pro 9i Aura Edition has also been announced for a launch in the US in Q2 2025, priced from $1,799. We’re still waiting to hear on other models, though, including the Yoga Pro 7i Aura.

European pricing (including VAT) is as follows, and as mentioned, these devices arrive later in March unless otherwise noted:

• Lenovo Yoga Pro 9i Aura Edition (16-inch): €1,699 (arrives June 2025)
• Lenovo Yoga Pro 7i Aura Edition (14-inch): €1,399
• Lenovo Yoga Pro 7 (14-inch): €1,399 (arrives April 2025)
• Lenovo Yoga Slim 7 (14-inch): €999
• Lenovo Yoga 7 2-in-1 (16-inch): €1,299
• Lenovo Yoga 7 2-in-1 (14-inch): €1,099
• Lenovo IdeaPad Slim 3x (15-inch): €599

• Perforce says it found an authentication bypass flaw affecting all versions of all software
• The flaw could grant malicious actors admin privileges on target endpoints
• A patch is being worked on, so be on your guard

Perforce recently discovered a major vulnerability affecting its entire software portfolio which could allow threat actors to gain full admin access without authentication. It urged its users to apply available mitigations while it works on releasing a patch.

The company said that a team of white-hat hackers found a vulnerability “affecting all versions of the platform” and posing a “severe risk to organizations worldwide, as it allows an attacker to gain full administrative access to the system without authentication.”

The bug is an authentication bypass vulnerability, affecting all versions of all Perforce software, it was said. The company reported it to global security databases, and currently awaits a CVE.

Authentication bypass

“This vulnerability compromises the core authentication protocol within Perforce software, allowing an attacker to bypass security mechanisms and take full control of the administration interface,” the company explained. This means that a threat actor could run system-wide admin commands, tamper with the data, escalate user privileges, run malware, and more.

Since the software is used in government, defense, and finance industries, and a patch has not yet been released, Perforce urges users to implement temporary security controls, including restricting admin access to trusted internal networks only, monitoring network traffic for unusual authentication attempts, and implementing additional firewall rules.

Furthermore, users should audit system logs for indicators of compromise, disable external access to Perforce servers where possible, and keep tabs on vendor announcements and security patches.

“Given the high risk associated with this vulnerability, security professionals, IT administrators, and businesses using Perforce.com software must act swiftly to secure their systems,” the press release concluded. “Perforce.com has been officially notified, and the security community expects an urgent response with mitigation measures and an emergency patch.”

Perforce is a version control system (VCS) designed for large-scale software development, enabling teams to manage and track changes to source code, digital assets, and configurations efficiently. Its flagship product is called Helix Core, a high-performance version control system designed for managing large codebases and digital assets, commonly used in game development, semiconductor design, and enterprise software development.

Just over a year ago, I reviewed the Anker Solix F3800 Portable Power Station, which is great; the only issue was that it was huge and heavy. So, while technically portable, it was not pleasant to move around. Since then, I have doubled my usage of the F3800, got another one, and had an electrician install the Smart Home Power Panel from Anker, plus a sub-panel that Anker offers to create a fully backed-up home/studio.

The F3800 is now offered in a package with just that, two F3800s with a smart home panel, and you can add on the sub panel depending on your use case. This package is designed to meet the rising demand and plea for electrical backup and sustainable power in this digital world.

Not only is this a residential power backup solution, but it also acts as the inverter and does all the heavy lifting if I want to add solar panels and cut back on my grid usage. All around, the F3800 was impressive, and one of the best portable power stations I've reviewed. Where it lacked is mitigated when you add another and the home power panel and shove this in your storage area behind your office, granting peace of mind for your home in case of severe weather or power outage, plus the opportunity to throw solar panels on your roof to collect some extra power from none other than the sun.

(Image credit: Collin Probst // Future) Anker Solix F3800 Home Power System: Price and Availability

This package from Anker is typically priced just north of $9,000. However, they are currently discounted to $5,599 with the code WSTDQR0929. There are options for installment payments through several different providers through Anker's website if needed, which is lovely as these are offered exclusively via Anker's website and have limited-time promotions.

Anker Solix F3800 Home Power System: Unboxing & first impressions

Since I already had one F3800, I was familiar with what it would be like to receive another. Nothing was different; the only new part was getting the power panel and the sub-panel. The Smart Power Panel was smaller than I expected, but I'm not upset because it fits better than I thought on the wall I picked.

Right now, I only have two F3800s. However, in the future, I will probably expand my battery capacity by adding a BP3800, which is just a battery unit that one of the F3800s could utilize. I could add up to 12 (6 per F3800) BP3800 batteries, each at 3840Wh capacity, totaling a whopping 53.8kWh battery capacity stored for my home.

Another thing I will add is solar panels. This time around, I did not grab any. However, I will probably add these in the future, especially since all I need are the panels and the cable to get down to my basement since I already have the inverter and batteries installed.

The setup process was straightforward; I called an electrician. In all seriousness, though, the electrician also had a pretty straightforward setup. He located my breaker in my basement, tailed off of that to connect to the Smart Home panel, and then integrated a sub-panel as well, so if I do have to power my home via these batteries, I can designate where that power is even able to go, prioritizing the essentials, and not having to worry about if there is something in my home that was left on that is not essential that would be a waste of battery.

After installing these, I could plug the cables from the power panel down to the F3800s, tuck them away, and then set them up through the app. I added my home, connected the unit to Wi-Fi, and then it registered that the F3800s were connected. From that point, I could see what I was pulling off the grid and set how much capacity I wanted the batteries to fill to (I chose a standard of 90%, with the ability to trigger "storm guard" that will quickly fill the batteries to 100% when I get an alert that there is a storm coming and then go back to my standard after that storm has passed) and the ability to set up other safety and battery preservation settings.

Anker Solix F3800 Home Power System: Design & build quality Specs

Output: 12kW (dual system) with 120V/240V split-phase support.
Capacity: 7.68kWh per unit, expandable to 53.8kWh with additional batteries.
Solar Input: Up to 2,400W, compatible with MC4-based solar panels.
Battery: LFP with an expected lifespan of 10+ years.
Charging: AC (1,800W) and solar (80% in 1.5 hours).

The overall design of this setup is quite sleek. I've seen some significant and cumbersome setups, and they always need to be placed outside because they have exhaust systems from gas generators.

The reasonably sized power panel can be mounted to the wall with two simple brackets. Lastly, the sub-panel can be mounted on identical cross beams to the power panel, making installation easy.

Anker Solix F3800 Home Power System: In use

So far, having my entire home backed up with battery power has been fantastic. It's freeing to know that, with my three kids and my wife, we can ensure that our house and what we need for the children are okay in a power outage. Any sound machines, heaters, fans, night lights, monitors for their rooms, security alarms, and so forth are all backed up in an emergency, storm that knocks out power, or grid outages.

Previously, in the "prepare for the worst" mindset that I have and my unique situation where I have a multitude of power stations on hand at any given time, I would have power stations set up around the house at key areas ready for a power outage as a UPS, or I knew that if I ever needed to, I could run down to my office and drag one of the big ones up to plug in the fridge, a heater, or whatever else I needed in the moment. Now, however, I don't have to do any of that. Granted, I still have the Solix C1000 running my main desk in my office, but that's simply because I chose not to include the finished part of the basement in my sub-panel so I could focus the battery on more important things that I don't already have a solution for such as the heat, stage one of my AC, fridges, kids rooms, primary bedroom, and the microwave. I also chose to have my living room backed up, knowing that my central unit for my mesh router system (review coming soon) and the modem is there.

Because of the draw of my stage one AC unit for my house, I opted for two F3800s to get the 12kW, as opposed to the 6kW that I could get with just one F3800.

Another great feature is that I can output at 120V or 240V, depending on the demand of the equipment. This means that if I wanted to, I could run my electric dryer, charge my not-so-real-but-maybe-in-the-future Tesla, or even run another stage on my HVAC.

All of this "preparing for the worst" is great, but what might be the coolest part of this setup is something that I haven't even mentioned yet. It's the fact that I could throw some solar panels on my roof or even in my yard if I wanted to, and I could harvest the sun to not only refill my batteries but help run my house in a power outage or even offset my grid usage. I could set this up to where, in peak hours (if I lived in an area with peak hours for electrical), I could pull from solar and battery power and then recharge in the lower hours, utilizing solar when I can and then pulling from the grid last, saving money on electricity. All of this could be set automatically, meaning that without even thinking about it or changing anything I am doing, I could save real money on electricity with this Anker SOLIX Smart Home Power Kit.

Anker Solix F3800 Home Power System: Final verdict

The Anker Solix F3800 Smart Home Power Kit offers a near-perfect blend of performance, scalability, and sustainability. While its steep upfront cost may give potential buyers pause, its ability to be both a backup solution and a solar powerhouse, saving you money on electricity every day, makes this an incredible two-birds-one-stone solution.

• Microsoft patches Paragon Partition Manager, after finding five flaws in a kernel-level driver
• One of the flaws was being actively used to drop ransomware
• The driver can be abused even without the partition manager installed

Hackers are using a vulnerable Windows driver to escalate privileges through Microsoft software, allowing possible ransomware attacks via zero-days.

Microsoft confirmed the findings when it added the affected version of the driver to its Vulnerable Driver Blocklist - and at the same time, it patched five flaws in the flawed software and urged users to apply updates as soon as possible.

The flaws were apparently found in BioNTdrv.sys, a kernel-level driver for a piece of software called Paragon Partition Manager. Cybercriminals who already managed to gain some access to a target endpoint would either use this driver (if the software is installed on the device), or drop it, to gain SYSTEM privileges in Windows, used to mount ransomware attacks.

Checking the blocklist

"An attacker with local access to a device can exploit these vulnerabilities to escalate privileges or cause a denial-of-service (DoS) scenario on the victim's machine," CERT/CC said. "Additionally, as the attack involves a Microsoft-signed Driver, an attacker can leverage a Bring Your Own Vulnerable Driver (BYOVD) technique to exploit systems even if Paragon Partition Manager is not installed. "

Microsoft said four of the flaws affected Paragon Partition Manager versions 7.9.1 and older, with the fifth one (CVE-2025-0298) impacting version 17 and older - which was also the one apparently being actively exploited in ransomware attacks.

Now, users are urged to upgrade the software to the latest version, since it also comes with BioNTdrv.sys version 2.0.0.

Besides upgrading the software, users should also double-check if the blocklist is enabled, by going to Settings - Privacy and Security - Windows Security - Device Security - Core Isolation - Microsoft Vulnerable Driver Blocklist and making sure it’s turned on.

• RayNeo announces launch month for RayNeo Air 3s glasses at MWC
• They're landing in April and only cost $259
• Despite being cheaper, they boast better specs than the last-gen Air 2s

RayNeo has set a release month for its RayNeo Air 3s XR glasses at MWC 2025 – with their budget-friendly smart specs due to land in April at a price of $259 (UK pricing to be confirmed). Based on what we’ve seen, these could be the affordable smart specs we’ve been waiting for.

These smart glasses serve as a wearable display for compatible tech like your phone, tablet, console, or RayNeo’s accessories such as its Pocket TV. They virtually project the screen in front of you like your own private movie theater – and even have in-built speakers to complete the package (though the small speakers can struggle at times)

Plus the Air 3s glasses boast several upgrades over the RayNeo Air 2s, with a 650 nits peak brightness, a larger eye box field of view, improved colors and contrast ratio, and all in a 2g-lighter 76g package.

They even look to handle the typically unimpressive audio you get from smart glasses with RayNeo promising its Air 3s glasses offer a 200% superior sound with improved highs, mids, and bass thanks to a new dual-speaker design. If that wasn’t enough, they’re also uber affordable with the new glasses costing almost half of what the $399 RayNeo Air 2s would set you back.

This marks the first of three smart glasses TCL and RayNeo plan to launch this year, with the RayNeo X3 Pro and RayNeo V3 (which we saw at CES 2025) due to land at some point too, though no specifics have been given yet.

The budget specs we've been missing

Smart glasses aren't cheap (Image credit: Future)

We’ll need to test them out for ourselves, but the RayNeo Air 3s glasses might just be the next best cheap smart glasses on our list of the best smart glasses if they can stick the landing.

These wearable displays are some of my favorite gadgets for travelling – whether commuting on a train or taking a flight – but also for using at home when I want to lie back in bed and still enjoy a big-picture experience with a show or movie. I just used a pair of Xreal specs I’m testing for a review on flights to and from Italy and they were perfect.

Unfortunately, many of this style of smart glasses aren’t the most affordable – typically landing around $400 / £400. What’s more, they can seem a little disappointing, usually offering audio that necessitates you get a pair of headphones (due to quality and sound leakage). They also typically offer merely full-HD image resolution, and you may need to buy an add-on like RayNeo’s Pocket TV or Xreal’s Beam Pro to feel like you’re getting a complete package.

At a lower $259 price, the RayNeo Air 3s makes some of these issues easier to stomach, and it sounds like the specs aren’t just settling for mediocrity either – lowering the price while simultaneously bringing upgrades over last-gen’s specs.

If they can live up to the hype, the RayNeo Air 3s specs might have put everyone on notice, and could be the glasses you need to buy if you want to dip your toes into the world of XR beyond the best VR headsets.

• The US government's General Services Administration department's 18F has been dissolved
• Elon Musk's Department of Government Efficiency seems to be behind the cuts
• 18F was a software and procurement group which helped a range of government agencies

A technology unit from the General Services Administration (GSA) has had its budget all but eliminated, affecting around 70 software engineers and strategists, as well as researchers, service designers, and procurements specialists.

The cuts were masterminded by Elon Musk’s Department for Government Efficiency (DOGE), and are part of an ongoing campaign to slash government spending.

Founded in 2014, the Unit, 18F, developed key public-facing IT services, like Login.gov - the central login system for services like Medicaid, Social Security, and Medicare. 18F was also responsible for helping government agencies buy and build technology, improve user experience, and make services accessible, and the unit collaborated with many departments, so the effects of the cuts will be felt across the board.

A sledgehammer approach

The department had previously been labeled as a ‘far left government wide computer office’ by a Musk supporter, to which the de-facto DOGE director replied “That group has been deleted”.

“All 18F's support on that work has now abruptly come to a halt,” the group said in a statement.

“Since the entire staff was also placed on administrative leave, we have been locked out of our computers, and have no chance to assist in an orderly transition in our work. We don’t even have access to our personal employment data. We’re supposed to return our equipment, but can’t use our email to find out how or where.”

These are not the first federal workers to be laid off, with over 110,000 federal employees leaving their posts since Trump took office, although around 77,000 of these accepted the administration’s deferred resignation program.

“Dismantling 18F follows the gutting of the original US Digital Service. These cuts are just the most recent in a series of a sledgehammer approach to the critical US teams supporting IT infrastructure.”

DOGE was also recently hit with a wave of lawsuits following complaints about the department breaching the privacy of millions of Americans by accessing “extraordinarily sensitive” details about federal workers and anyone who has ever applied for a federal job.
