There are plenty of 4K TVs available to buy these days, but the ones we’ve hand-selected here truly stand out as the best of the best.
If you want to do real justice to 4K HDR, then buying a cheap TV won’t really offer the benefits you’re after. Instead you’ll need to buy one of the best 4K TVs on our list, which have all been selected for different budgets.
We’ve aimed to include at least one model from each major manufacturer. Every TV has been tested and reviewed by our expert team.
They’re assessed by how easy they are to assemble, how long it takes, how easy they are to use, the level of feature support they have in comparison to toher models. They are, of course, all put through their paces when it comes to picture and sound testing.

The 4K TVs on our list are all £1,000 or above. If you’re looking for something a bit cheaper, we’d recommend taking a look at our best cheap TV list. If you’re looking for other options, our comprehensive best TV list will give you the answers.
Every TV we review is put through the same set of tests to gauge its picture performance, usability, and smart features.

Tests are carried out over several days and are done by eye but supported with technical measurements. Testing by eye involves an expert watching a wide range of material to understand and determine a TV’s performance in fields such as brightness, contrast, motion processing, colour handling and screen uniformity.
We’ll consider the design of the TV in terms of build quality, study the spec sheets and see if the TV’s connections are up to spec, as well as playing video and audio content to ensure that the set handles playback as it claims. We also take note whether a product’s compatible formats and features are in line with industry trends or not to gauge whether it’s relevant for you.
Comparison to other related and similarly priced products is also important, to see if it’s missing any vital features and whether it impresses as a whole. After all this, we’ll come to a judgement on how the TV performs as a whole.

The LG OLED55G5 (G5) is simply an outstanding 4K TV. Not only does it boast a vibrant and colourful picture, but its upscaling and processing capabilities are up there with the best. Plus, and unlike some other OLED panels, the LG G5 is impressively bright too.
If you opt for the 48-, 55- or 65-inch models then you can choose between the wall-mounted option or a version that comes with a stand. However, anything over 77-inch will only support wall-mounting, so keep that in mind.
Advertisement
The LG interface is easy to use and can be controlled either via the included remote or through LG’s ThinQ smartphone app. There’s no lag and the amount of content doesn’t overwhelm like the Fire TV. However there’s no Freeview Play support and, instead, you’ll see LG Channels.
Gamers will appreciate ALLM which we tested had an input lag at 13ms in Standard and 9.3ms in Boost modes. In addition, the G5 can hit up to 165Hz in PC games, has VRR compatibility in AMD FreeSync Premium and includes the LG Game Optimizer for deeper customisation in game.
Sporting a Primary RGB Tandem panel, where the G5 really impresses is with its brightness, and can hit a peak of 4000 nits. That’s seriously impressive for an OLED TV.
We should note that although there’s no unsightly green tint on display here, which is an issue we’ve seen with other LG TVs, we have concluded that it can’t quite match a Mini LED panel. However, that’s not an issue with just the G5 as not many OLEDs can match a Mini LED’s performance.
Advertisement
Another area where the G5 excels is with upscaling, as 1080p content could be mistaken for a true 4K image.
Generally sound quality is decent enough, with dialogue especially sounding clear and natural. However, lower frequencies bring out some buzzing and it can sometimes lack the energy of other TVs. With this in mind, it might be a good idea to invest in one of the best soundbars.

Where’s IMAX Enhanced?
The Philips 65OLED+910 is a terrific OLED TV from the brand, with a bright and detailed picture, an affordable price tag and one of the best built-in sound systems we’ve tested.
The sound system is courtesy of Bowers & Wilkins, and sits at the bottom of the OLED910. It’s wrapped in a fabric that gives the TV a warm, lifestyle feel which is a nice touch too. However, most importantly, the sound is powerful with a spacious soundstage and clear dialogue. We don’t even think you need a soundbar with this one.
Advertisement
Otherwise, the OLED910 is fitted with the same RGB Tandem screen used in the LG G5 and supports HDR10, HLG, HDR10+ Adaptive and Dolby Vision. While there’s no IMAX Enhanced support, there’s also Dolby Vision x Filmmaker Mode that combines the two.
Annoyingly, out of the box the OLED910 has Auto Film Picture Style enabled which makes motion seem more stuttery. You’ll have to dive into the settings to turn this off, but once you do the difference is unmistakable.
While the TV isn’t as bright as the likes of the LG G5 or Samsung S95F, where the Philips excels is with its contrast and level of detail. Even the divisive Crystal Clear picture mode looks excellent, although some films don’t seem to quite suit it as well as others.
Upscaling is solid too, although there are options that do a better job as refining details.

Finally, the OLED910 runs on Google TV which, although is easy enough to use, does have a few apps missing – mainly BBC iPlayer. You can stream iPlayer via Google Cast but a built-in solution would be better.

The arrival of the Samsung QN90F marks a big change in Samsung’s approach to its TV in that its OLEDs are as important if not more so than its LCD TVs.
It has an RRP of £2499 / $2499, which doesn’t make it the most affordable at launch and a little over the price point we have in mind for this list. But if you’re willing to wait, the price will eventually come in the months ahead.
Peak brightness is a scorching 2500 nits on 10% window, making this a suitable TV for those in need of a bright TV or watch in a room with lots of ambient light. There’s a big step up in AI processing from the QN90D’s 20 neural networks to the QN90F’s 128.
Advertisement
This extra AI horsepower helps to upscale non-4K images in a clean, crisp, and natural way thanks to its ability to tell the difference between detail and noise.
With 4K HDR content, the TV pumps out some rich and vibrant colours, although our reviewer did find that its pictures can look overly vibrant at times. Regardless, the processing produces supreme levels of detail and sharpness. Local dimming is effective though we did note some blooming around bright objects.
The sound system is on the impressive side for a flatscreen TV. It offers power, clarity and space, confidently planting sounds across the screen and beyond its frame. Bass remains limited but that’s to be expected.
For gaming, all four HDMI inputs support 4K/144Hz with 165Hz available for PC gamers. There’s HDMI VRR as well as AMD FreeSync Premium Pro. We measured input lag to 9.2ms, which is lightning fast and the best on the market.

The latest Tizen smart interface is better than previous ones offering a more polished, content-first approach. It’s quick to load and there’s customisation on the table in the form of re-ordering apps.

TCL has made a name for itself in offering high-spec TVs at lower prices, and the 65C8K is the perfect solution for those who want maximum value at affordable prices (for a 65-inch 4K TV).
The 65C8K has a huge levels of brightness at its disposal, and this leads into a colour performance that’s both vibrant and natural looking to the eye. And despite the near 4000 nits of brightness that this TV can summon, it does a very good job at producing solid black levels when it needs to.
Compared to Fire TV OS which tends to prioritise Prime Video content, Google TV does a good job of gathering content from all of your available subscriptions in one place. If you know exactly what you want to get to then you can use Google Assistant voice control to ask for it.

Gamers will benefit from ow input lag (13.1ms), VRR support and refresh rates up to 165Hz to offer smooth, fast gameplay, especially if you’re a PC fan.
When it comes to the default sound profile of most TVs, we usually recommend that consumers pick up a soundbar, but this isn’t immediately the case with the TCL 65C8K.
With speakers that have had input from Bang & Olufsen, there’s an impressive degree of clarity and detail, although we would have liked a bit more power to the bass levels.

If you’re the type of person who likes to keep a minimal, clutter-free entertainment unit in their living room then you’ll probably want to consider the Panasonic TV-65Z90B as your next upgrade. Panasonic’s stunning set is one of the best TVs we’ve reviewed in terms of offering a complete, all-in-one experience across visual and audio quality, not to mention gaming chops and smart features.
Advertisement
Starting with the image quality, there’s nothing about Panasonic’s offering that’ll leave you wanting. The OLED panel brings true-to-earth colours to life, with a brightness that draws you in and a contrast that only heightens the darker elements of a scene through deep, true blacks. What’s even more impressive for a modern TV is that the sound quality is right up there with some of the best we’ve tested.
Typically as TVs have continued to slim down, the potency of built-in speakers has diminished in tandem, but the TV-65Z90B packs quite a punch on the audio front, right from the get-go. There’s a tangible weight to the bass that really helps to bring forth the expression of explosions and punches, but more importantly it’s the dialogue that comes across with outstanding clarity, so you won’t be struggling to hear what’s being said.
Keeping in tandem with the idea of having an all-in-one device without the need for accessories, the Panasonic TV-65Z90B utilises Amazon’s Fire TV operating system by default, providing users with quick access to all of the major streaming services, either via the remote which includes a wealth of dedicated streaming service buttons, or the Alexa voice assistant.
If you do have a console nearby however then you’re in for an absolute treat. With a 144Hz refresh rate alongside next to no input lag, you can kick back and enjoy a whirlwind of a gaming experience that brings more fast-paced titles to life. The Game Control Board also lets you toggle various visual and audio modes that are designed to make the most out of certain genres.

We concluded that the Hisense 65U8Q is the best Hisense TV we’ve ever reviewed here, thanks to its picture quality, impressive brightness and a solid sound system that outranks the LG G5.
Available in three sizes (55-, 65- and 75-inches), the U8Q is quite a hefty TV and weighs a whopping 29.2kg and has a depth of 45mm. It’s certainly not the slimmest, but that shouldn’t be too much of an issue for many.
The U8Q runs on Hisense’s VIDAA interface in the UK which is a simple operating system and includes all the apps you’d expect from a smart TV. It’s not the most polished OS, but it’s easy enough to use.
All HDR formats are covered here, and the processing is performed by Hisense’s Hi-View Engine Pro which can optimise picture and sound in real-time.
Advertisement
Although some blooming is noticeable, the U8Q is easily as bright as a Mini LED TV, and recorded 857 nits on 100% HDR window – that’s the brightest full screen output we’ve seen. In addition, the black level and bright highlights offer a Samsung-esque performance too.
When it comes to audio, while it doesn’t quite have the same punch and force as the Philips 65OLED809, there’s enough power that you don’t often get with a TV. While we’d still recommend pairing it with one of the best soundbars, it’s still a better overall performer than LG and Samsung TVs.
Gamers are covered here too, with AMD FreeSync Premium Pro VRR, 165Hz refresh rate for PC gamers, or 120Hz for console users, and ALLM which automatically puts the TV into its lowest latency – which we measured at 13.5ms.

The Sony Bravia 8 replaces the Sony A80L, but you could more or less say it’s the same TV.
Advertisement
There are a few differences in terms of picture quality, with the Bravia 8 OLED reaching higher levels of peak brightness in some modes (Professional, Vivid) but less in others (Cinema Standard).
There are slight improvements over the A80L with a richer, bolder HDR performance that looks lovely when paired with colourful films and TV series. Motion processing is again excellent, smooth and with very few issues noted, while contrast is strong for an OLED TV although we did notice some crushing (loss) of detail with its black levels.
We’d love for Sony to push the brightness out more for this OLED, but for those who want a brighter HDR performance, the Bravia 8 II is set for launch in June 2025.
We’d recommend the Bravia 8 as one of the best Sony TVs for PS5 owners. It includes Auto Genre Picture mode that automatically switches the TV in and out of its game-ready state so the A80L isn’t stuck in game mode all the time; along with Auto HDR Tone Mapping enhances the HDR performance for best brightness and contrast.
Advertisement
Dolby Vision Gaming is supported and the TV does also include 4K/120Hz and variable refresh rates (VRR) across two HDMI 2.1 inputs (one of which is shared with the eARC port). We measured input lag at 12.7ms, which is as good as the LG C4.
The sound quality is fine though not as dynamic or as loud as the A80L.
We’d recommend you consider adding a soundbar or sound system, and Sony has plenty including its Bravia Theatre Bar 8 and the Theatre Sound System 6 to choose from.

At a jaw-dropping 98-inches, the TCL 98C7K is not a TV that’s designed for everyone. However, if you have the space and want to truly immerse yourself in a massive screen, all for a surprisingly reasonable price tag, then the TCL 98C7K is an easy recommendation.
Advertisement
Although it’s such a mighty screen, there’s very little supporting bodywork around it, with a narrow frame and such slim feet that they become almost invisible when viewing the TV head-on. Speaking of the feet, keep in mind that they’re annoyingly set quite far apart from one another, so you’ll need a hefty piece of furniture to place it on top of.
The 98C7K runs on Google TV which is a decent enough interface, and includes all the apps and even the main UK terrestrial broadcaster catch-up services you’d expect. Not all Google TVs offer that.
While Google TV can be overwhelming to use at times, it’s easy to get your head around and usefully supports Google’s voice assistant too.
With the above in mind, let’s jump to the star of the show: the panel. The Mini LED lighting system is divided into 2048 separate local dimming zones – enough to provide even a screen this big with promisingly localised light control. Considering it can hit almost a peak of 3000 nits, this is a necessary addition.
Advertisement
The panel also supports wider viewing angles than most LCD TVs while TCL’s AiPQ Pro processor is on hand to keep things running smoothly.
Overall, the 98C7K’s picture quality is seriously a vision for such an affordable yet mighty TV. In its Standard preset, which is the one you’re likely to use the most, images are bright and vibrant, with the screen covering more than 97% of the DCI-P3 colour spectrum and near 80% of the BT2020 spectrum too.
A key feature of the 98C7K is its Bang & Olufsen-assisted sound system which delivers a refined, clean and detailed tone. It’s not the best at handling bass, especially when compared to the dedicated subwoofers previously used in premium TCL TVs, but it certainly does the job.
Although it has an RRP of £2399, which feels reasonable given the size and performance, it’s not impossible to pick up the TCL 98C7K with a decent price cut too. With that in mind, if you want a mighty screen, this is a hard option to beat.

It should be noted that the Gen 2 version of Sky Glass is an improvement over the Gen 1 version, but that doesn’t make it a TV designed to satisfy everyone.
If you’re a home cinema enthusiast, a gamer or even just a casual TV watcher, there are better TVs on this list. But if you have a family, or are someone who is not interested in the complications of the TV buying experience. Sky Glass 2 is practically ideal for you.
Firstly, the installation is handled by the courier team that delivers the TV to you. If you want it on a pedestal or hauled onto your wall, they’ll carry that out and take the packaging away so you don’t have to worry about it. The TV itself is the same dimensions as before, so it’s a chunky effort, but it’s lighter, so if you ever feel the need to move it, it won’t be such a difficult task.
Sky OS doesn’t feature every entertainment app on this earth, but it does feature the popular ones whether it’s the UK catch-up apps, Netflix, Disney+, Prime Video, Apple TV+ and an assortment of others.
Advertisement
And what it does as good as any other TV interface is that it does not treat them any differently from one another. All Sky wants is for you to tuck into whatever it is that you enjoy.
The rails of content are there to help you plunder what you like more easily, with Sky OS getting to know what you like over time and personalising those recommendations further.
The Playlist section acts as a way to keep track of what you want to watch, and you can create different personalised playlists for everyone in your household. The interface is quick, and the voice control has become more accurate and responsive over time.
The picture quality is much improved over the original model. It’s brighter without as much blooming, better with colours and handles the darker parts of the picture better than it did before. It’s not the sharpest or most detailed image though, and the upscaling is patchy, with stripey colours noticeable with HD programming.

The built-in Dolby Atmos sound system is described as offering more power over the Gen 1 version, but to our ears it doesn’t sound too much different. It’s a spacious and tall sound, but like the picture quality, it’s not the clearest or most detailed performance. But considering the competition it’s up against, it’s a better effort at TV sound than most.
For those who want their TV, sound and content all wrapped into one convenient package, Sky Glass Gen 2 will be a compelling option, especially if you’re not fussed about getting the highest quality image and sound. It does come at a premium once all the subscriptions are tallied up, but Sky does have a cheaper option with its Glass Air TV.

Senior engineers are retiring faster than companies can replace them, creating a widening expertise gap in industries from aerospace to nuclear energy.
Hera, a project developed by University of Washington students, is aiming to address the issue with technology that automates the design of parts that meet safety and industry rules, a process that normally requires many years of knowledge and experience.
The product is timely, as 1.9 million manufacturing jobs are expected to go unfilled in the $2.3 trillion sector by 2033, according to Deloitte.
“Hera answers design questions 10-times faster than a senior engineer,” said Meera Patel, co-creator of Hera. “Once it knows the drawing can be manufactured, it pulls data from all your machines and gives you an exact production plan.”
That’s one of several problems University of Washington students tackled through DubHacks Next, a 16-week startup incubator. On Thursday, May 7, student founders pitched 20 startups hoping to turn their ideas into viable companies.
Advertisement
Since 2022, DubHacks Next has spurred 68 startups and at least 25 active companies. Participants get access to free workshops, mentorship sessions, customer discovery meetings and networking with potential investors.
This year’s batch of 20 startups includes AI salon receptionists, a student subleasing platform and an emotional recovery app.
“I’ve never had the experience of building such a large-scale idea and bringing it to life,” said William Pantel, co-developer of Catalvst, an AI audio plugin builder.
The incubator’s past projects have raised more than $5 million collectively, with alumni going on to join accelerators such as Y Combinator and Techstars or land jobs at major tech companies.

Starting this year, students could apply to join the Pack Ventures portfolio, including $50,000 up front and $150,000 when another firm buys in.

Patel and Hera co-creator Noelle So are among the students working with Pack. The demo is now live in three production plants, Patel said.
Here are more standouts from this year’s batch:
Chameleon: For the 1.3 billion people living with disabilities worldwide, nearly 96% of the internet’s top homepages are considered inaccessible. Enter Chameleon, an AI-powered web accessibility tool suite.
The suite includes a Chrome extension with tools like focus rulers, voice commands and head-tracking controls for accessible web navigation on any site, say co-founders Aditya Shirodkar and Ajit Mallavarapu.
Advertisement
“Especially with vibe coding, people are quick to develop software and don’t think about accessibility needs,” Shirodkar told GeekWire. “It’s a silent barrier that isn’t really addressed.”
Chameleon is entering a market with growing need – and financial opportunity. The global digital accessibility market is estimated at $1.8 billion, and is projected to reach $3.2 billion by 2034, according to Straits Research.
“It’s not just about making something cool,” Mallavarapu said. “It’s about making something people will actually use every day.”
Iris: Sthiti Patnaik and Saachi Dhamija focused on another technological headache: spreadsheets.

Universities often rely on sprawling spreadsheets to track alumni for fundraising, networking and event planning, but records quickly become outdated and difficult to search. With Iris, alumni associations and other groups can more easily maintain member databases.
“We ingest their spreadsheet, then present it in a more visual format with bubbles and graphs,” Dhamija told GeekWire.
Along with data enrichment and interactive visual mapping for organizers, Iris helps members discover one another through shared experiences and interests. Patnaik, a recent graduate and managing director for DubHacks Next, hopes the solution will help her stay connected to other founders.
“All of our alumni go on to do really fantastic things, such as raise money, start their own startups, or work at really great companies,” she said.

After presenting Iris, Patnaik and Dhamija landed a design partnership with Pack Ventures.
Catalvst: For Aaron Li and William Pantel, the incubator became a launching pad for Catalvst, what may be the first-ever AI audio plugin builder.
High-end audio plugins – software tools that shape and manipulate sound – can cost music producers hundreds or even thousands of dollars. Li, who began producing EDM three years ago, said software costs have delayed his progress.
“I remember working all summer just to save up,” he said. “It’s a domino effect. You get one piece of software, and realize there’s another one you need that’s super expensive.”
Advertisement
With Catalvst, users can describe the sound they want in plain language and generate downloadable, working audio software in under a minute.
“If you’re like, ‘I want my songs to sound like I sing them in a cathedral,’ it’ll create software that makes your song sound like that,” Pantel said.
The founders distinguish their product from AI-generated music platforms, emphasizing that their goal is to empower human creators rather than replace them. They’re currently beta testing with music producers to refine the product and grow its user base.
“We’re using AI to build tools human producers can use,” Pantel said.

Applications for the incubator’s sixth batch open this fall.

BeamBell: AI salon receptionist | Arvin Hakakian, Anant Dhokia, Aur Shalev Merin
European diesels can be had at both ends of the spectrum; there are magnificent ones like Audi’s 12-cylinder, and catastrophic failures like Land Rover’s inline-six. Over here in America, we tend to associate diesel engines almost exclusively with trucks and heavy machinery, but Europeans have been doing things a little differently for the past three decades or so. It’s not uncommon at all to see a diesel-powered sedan or hatchback on the continent, although newer models in the region are gradually ditching diesels too.
Aside from the cultural acceptance of diesels in Europe, there were also emission laws so strict that CARB — the reason why you can’t get the new Hemi V8 in some states — would be put to shame by comparison. As a result, the amount of innovation in European diesel engines was much higher, and that’s why we got some truly spectacular engines out of it. And it’s not like these were three-cylinder econobox engines either; the Germans were busy stuffing V10 diesels into anything they could get their hands on, from a family SUV to an executive sedan, and pretty much everything in between. But where there’s trial and experimentation, there’s also error. So it is with Euro diesels, because we also got some real dogs along the way, two of which we’ll cover here. One was subjectively the worst engine from a brand already famous for unreliability, and the other treated timing chains like a consumable item.

Best: Audi 5.5 V12 TDI
First up, a V12 from Audi, which is one of the many car brands that Volkswagen owns. The Volkswagen group had made many legendary diesels at the time, including a V10 for the Phaeton and Touareg, and a V12 diesel for the Q7. For the V10 production version, the final unit ended up being a five-liter engine, with the TDI suffix indicating that it used diesel injection. The cars it powered were the Phaeton, where it made 313 hp and 553 lb-ft of torque, and the Touareg, where the final power output stood at 310 hp and the same torque.
As you can imagine, these cars were blisteringly quick, with the Touareg managing a 0-60 mph time of an estimated 7.5 seconds. Later on, Audi would make their own V12 diesel engine for their Le Mans LMP1 race vehicle. This car, called the Audi R10, got a 5.5-liter version of the engine, but with 12 cylinders making 650 hp and 811 lb-ft of torque, and to say that the Audi dominated the next season would be an understatement.
Advertisement
With its newfound diesel powertrain and 12 cylinders, the electronically limited Audi R10 LMP1 romped home to victory in several races, and even took home overall victories at Le Mans three times. In doing so, the Audi R10 became the first diesel car ever to win Le Mans — and it ran on biodiesel.

Best: BMW M57
While BMWs don’t exactly have the best reputation when it comes to reliability — we’ve all seen the oil leak and check engine light jokes online — the BMW M57 diesel is an exception. The engine was a three-liter, six-cylinder unit with the cylinders arranged in an inline configuration, and it came with turbochargers as well, of course. BMW has had a long history of making diesel engines even for passenger cars, such as the widely used M47 and B57, though these are not considered as reliable as the M57 that we’re looking at.
It was first released in the U.S. for the 2009 model year, though it had been in production since 1998, and the U.S.-spec version made 265 hp and 425 lb-ft of torque. It was offered in many mainstay models from BMW, initially in the 335d sedan and the X5 SUV. In the 335d, which is arguably the most famous of the models we just listed, the M57 could push the car from 0-60 mph in about 5.7 seconds and gave the car the ability to run the standing quarter-mile in 14.2 seconds.
While somewhat average by modern standards, remember, this was back in the late 2000s, when even supercars like the Aston Martin Vantage had 0-60 mph times of around 4.7 seconds. With all that said, there are certain years where the BMW M57 diesel engine should be avoided, but overall, it was a pretty solid option that delivered on all fronts.

Best: Volvo D13
There aren’t many people who’ve heard of the Volvo D13, but if you’ve ever bought anything from Europe, there’s a decent chance part of its journey involved a truck powered by a Volvo D13. Widely considered to be the best truck engine that Volvo has made — though there have been newer versions released at the time of writing — the D13 has powered trucks like the Volvo VNR, VAH, VNL, and VHD, all of which are part of Volvo’s North American lineup. Displacing a herculean 12.8 liters across six inline cylinders with a bore of 131 mm and a stroke of 158 mm, this 2,635-lb engine is primarily a diesel variant that makes between 1,450 and 1,900 lb-ft of torque at a relatively low 900 RPM.
This is in addition to a maximum power output of 500 hp, with peak hp available at 1,300 RPM — and while the utility of this power would largely be dependent on the choice of transmission in the truck, it’s still impressive nonetheless. As with many truck engines, there are different power ratings available, with the lowest variant of the D13 coming with 405 hp and 1,450 lb-ft of torque, while the top-of-the-line variant makes the aforementioned 500 hp and up to 1,900 lb-ft of torque.

Also, we said “primarily” a diesel variant because there is also a very similar engine from Volvo called the D13-LNG that runs on natural gas, which is generally understood to be a cleaner fuel source than diesel.

Worst: Land Rover 2.0 Ingenium
Widely considered to be the worst Land Rover engine ever made by experts and users alike, the 2.0 Ingenium was introduced to the world in 2015. The inaugural version was used to power the Jaguar XE, though it was later also slotted into the Land Rover Discovery Sport and Range Rover Evoque. The displacement is two liters across four cylinders , and is turbocharged. On paper, the 2.0 Ingenium is quite powerful, making at least 197 hp along with 236 lb-ft of torque, though models with higher power outputs are available.
In real life, however, everyone — from end users to industry experts — has a laundry list of woes. First up, there are reliability concerns that are too numerous to name, but the big and unfortunately common ones are oil dilution, timing chain breaks and rattles, and the turbos flat-out failing. However, the silver lining in there’s the fuel economy; the Discovery Sport with the 2.0 Ingenium diesel engine netted a 58 mpg figure on launch in 2015, according to Land Rover. Note that the European fuel economy measuring test (NEDC at the time, WLTP today) is different from the EPA system used in the U.S., so the readings aren’t exactly the same.
And lastly, mechanics seem to dislike working on the engine too, complaining about things like component placement and the engine generally being troublesome to work on. All of the above, coupled with the frequent breakdowns, make it one of the most horrible things to come out of Land Rover.

Worst: BMW N47
Where the BMW M57 that we looked at above was a star, the four-cylinder N47 that made between 94 and 215 hp was the complete opposite. It first entered BMW’s lineup in 2007, where it remained until 2014, marking a production span of about seven years, but it’s easy to see why the engine was quickly discontinued. For starters, let’s first say that the selling point for the N47 was its efficiency; in the 2009 BMW X1, it was able to net an impressive 48 mpg combined fuel economy figure across city and highway driving. Again, the European testing methods would differ from the EPA’s methods, so bear that in mind.
However, this was an engine that treated its timing chains like a consumable item. Furthermore, like many other BMW engines the timing chain is located at the back of the engine bay. As such, when something goes wrong that needs a timing chain replacement, the labor is prohibitively expensive and time-consuming.
Advertisement
Other issues that plague the N47, albeit to a lesser degree than the timing chain woes, include premature turbocharger failure, high oil consumption, and a whole suite of problems with the EGR, or exhaust gas recirculation system. To be clear, we’re not saying that it’s inevitable that the N47 will be a dog, but it’s highly likely that maintenance bills for this engine will be higher than usual. Unless your heart is really set on one, it’s probably best to go with another option.
More than 4,000 Hollywood insiders recently signed a letter blasting Paramount’s planned $111 billion merger with Warner Brothers, noting that the massive consolidation will be very historically harmful to labor, consumers, and creatives. That’s a very correct observation, especially as it relates to Warner Brothers, which has never been involved in a merger that didn’t result in mass layoffs, higher prices for everyone, and a significantly shittier overall product.
Now a coalition of press groups, including Freedom of the Press Foundation (FPF) and Reporters Without Borders, are pressing Paramount regarding “potentially corrupt acquisitions and deals” they argue could undermine shareholder value by degrading the (already sagging) quality of journalism at CBS News and CNN, while “relinquishing editorial control of major news outlets to the Trump administration.”
The journalism groups make the point that the Ellison family effort to turn CBS into a Trump and Netanyahu-friendly agitprop machine has been disastrous for the company’s share price. And because both organizations are technically shareholders, they’re demanding deeper access to the Paramount books to see what other dodgy bullshit may not have been revealed yet:

“Since Paramount Skydance announced its most consequential Trump-friendly changes at CBS News in October — acquiring The Free Press and appointing Bari Weiss as editor-in-chief — the company’s market capitalization has decreased by 40%, wiping out more than $8 billion in shareholder value. Ratings for key programs, like “CBS Evening News with Tony Dokoupil,” have also dropped precipitously. Freedom of the Press Foundation and Reporters Without Borders, which are both shareholders in Paramount Skydance Corp., are entitled to inspect the company’s books and records related to these developments under Section 220 of the Delaware General Corporation Law.”
They’ve given Paramount five days to respond to their request for more documents and data related to any promises Paramount may have made the Trump administration. I’m not convinced the gambit will go anywhere, but it’s nice to see these kinds of groups (historically absent from many of these fights) suddenly paying closer attention to media consolidation.
Larry Ellison’s interests here are two-fold. He wanted to gift his nepobaby son David with two major Hollywood studios so David can pretend he’s a very big boy doing very serious things. But he’s also keen on dismantling what’s left of journalism at places like CBS News and CNN (already reeling from years of corporate cowardice) turning them into right-wing friendly agitprop mills that are even more friendly to his favorite autocrats (Trump and Netanyahu).
You’ll recall Bari Weiss sold herself to Paramount as an expert who could modernize CBS News through virality and mass audience appeal (despite having no actual experience in journalism). But Weiss, who got her start at the helm of a strange contrarian troll blog, has the instincts and ideas of a 90 year old man, and clearly isn’t capable of generating watchable propaganda in any ratings-grabbing way that actually appeals to anyone (even MAGA folks, who already have no limit of agitprop options).
The Trump administration will certainly rubber stamp the deal. Paramount will likely keep this effort locked up in the courts indefinitely. And the Democrats’ demand for the FCC to investigate the dodgy Chinese and Saudi financing propping up the deal isn’t likely to go anywhere. That leaves a collaborative looming lawsuit by state AGs as the most likely path toward ensuring this deal never gets off the ground.

But even if the deal gets approved, this giant company’s long-term survival is far from guaranteed. Especially given the shaky state of Hollywood, the steady enshittification of streaming, and the fact that there’s very little evidence that the any of the Paramount folks are competent.
There’s a very high likelihood that the combination of Paramount’s massive debt load from both the CBS and Warner deals– and fleeing audience (either bored by bad product or disgusted by the companies’ Trump allegiances) — combines with Larry Ellison’s over-extension on AI to result in some very precarious financial footing.
These major media deals always go terribly for consumers and labor, but execs often benefit from tax breaks, temporary stock boosts, and compensation in no way dictated by competency (see: CEO David Zaslav). But this series of deals is so massive and problematic, it could generate some very significant pain for the extraction class, and make all past merger disasters seem adorable by comparison.

Gartner’s report found that organisations need to invest in a workforce that can lead the transition to autonomous capabilities.
Over the course of the last year, there have been a range of high-profile layoffs as a result of the continued investment into AI and its capabilities.
Recently, Cloudflare announced plans to cut 20pc of its workforce after AI usage at the company grew by 600pc in three months and in April, social media and tech platform Meta told staff that it will be laying off 10pc of its workforce, roughly 8,000 employees, reportedly as a means of mitigating the costs of heavy AI spending. Similarly, Snap is laying off 16pc of its workforce to cut costs and focus on AI.
Gartner surveyed 350 globally dispersed business executives in the third quarter of 2025, to better understand the state of autonomous business at enterprises. Qualifying organisations reported enterprise-wide annual revenue of at least $1bn or the equivalent, and had been piloting or had already deployed either an AI agent, intelligent automation or autonomous technologies.

Of the organisations taking part in the piloting or deployment of autonomous business capabilities, roughly 80pc admitted to reducing their workforce. Gartner’s research found that these reductions do not appear to translate to a return on investment (ROI) for the organisations making the changes.
The survey found that workforce reduction rates were nearly equal among respondents that reported a higher ROI from autonomous technologies and those that experienced only modest gains or negative outcomes.
Commenting on the findings of the report, Helen Poitevin, a distinguished vice-president and analyst at Gartner, said, “Many CEOs turn to layoffs to demonstrate quick AI returns – however, this disposition is misplaced.
“Workforce reductions may create budget room, but they do not create return. Organisations that improve ROI are not those that eliminate the need for people, but those that amplify them by aggressively investing more in skills, roles and operating models that allow humans to guide and scale autonomous systems.”

Despite increased layoffs as a result of AI adoption, Gartner’s research suggested that, while autonomous business will continue to increase alongside AI agent software spending, “the need for people will go up, not down”. To that point, Gartner predicts that “autonomous business will be a net-positive job creator by 2028 to 2029, driven by new forms of work that AI cannot absorb”.
“Long term, autonomous business will create more work for humans, not less. Lasting structural factors such as demographic decline and high-stakes, trust-dependent consumer moments will ensure human talent remains central to running, governing and scaling autonomous business,” said Poitevin.

As wireless communications technologies such as Wi-Fi (IEEE 802.11) and cellular (LTE, 5G NR) continue to demand higher data throughput, the modulation schemes used to encode information have grown increasingly complex. Modern systems employ quadrature amplitude modulation (QAM) with orders up to 4096QAM, where each symbol carries twelve bits but the constellation points are extremely close together. This makes modulation accuracy critical: even small deviations in amplitude or phase can cause bit errors. Error vector magnitude (EVM) has become the primary metric for quantifying this accuracy. This white paper covers the fundamentals of digital modulation, defines EVM and its calculation methods, explores the common sources of EVM degradation, and explains how constellation diagrams can be used to visually diagnose the root causes of modulation impairments in practical wireless systems.
Humanoid robots are a thing now, and here’s an interesting research project that explores using one as a form of haptic media. Specifically, using a humanoid robot to move a chair while one plays a VR driving simulator.
Here’s how it works: a Unitree G1 robot sits behind a player’s chair and grasps it with its hands. Spherical markers on the chair help the robot’s depth camera know the chair’s position, and real-time G-force signals fed from the simulator (Assetto Corsa, running on PC) tell the robot how much and in what direction to shift the chair to match in-simulator events.
While a humanoid robot (especially one equipped with articulated, human-like hands) makes for an awfully expensive force feedback chair, this approach is interesting because it specifically explores using an already-existing humanoid robot as a general-purpose device. It sits in a chair, looks with its camera, grasps with its hands, and moves the player’s chair in response to game events; no hardware modifications required.
So how well does it work? Pretty well, apparently! Participants found the synchronized motion feedback accurate and highly enjoyable, although it does seem like there were some rough edges. Some testers reported that the sustained motion and constant vibration were tiring, and in some cases seemed to worsen VR sickness.
Summer is when pools move from being part of the setup to becoming part of everyday life. What starts as a manageable routine quickly turns into regular use, whether it is weekends with family, hosting friends, or simply spending more time outdoors. It is also when maintenance stops being occasional and begins to demand consistency, which is where most systems start to fall short.
Surface debris returns faster than expected, shallow areas remain inconsistent, and steps that were meant to be automated begin to come back into the routine. What looks simple at the start of the season starts to take more time than it should, especially when the pool is being used more often.
Beatbot positions the Sora 70 as a way to remove that friction altogether. Built as a 4-in-1 cordless system, it brings together water-surface cleaning, waterline scrubbing, wall climbing, and floor cleaning into a single workflow that reduces the need for repeated intervention. More than that, it fits into how pools are actually used during the season, making it a practical upgrade for homeowners and a high-value gift for those investing in easier, more usable outdoor living. With the Anniversary Campaign running from May 9 to 25, it arrives at a point where that shift becomes both relevant and easy to act on
A 4-in-1 system designed to replace fragmented pool cleaning
Most robotic pool cleaners still leave gaps in how cleaning is handled. Floors are covered, walls are managed, but surface debris, shallow platforms, and waterline buildup are often left to separate tools or manual effort. That fragmentation becomes more visible with regular use, when no single cycle fully resets the pool and maintenance starts to return in smaller, repeated steps.

The Sora 70 is designed to replace that fragmented approach. Its 4-in-1 system brings together water-surface cleaning, waterline scrubbing, wall climbing, and floor cleaning into a single cycle, reducing the need for multiple devices or follow-up passes. Instead of dividing the process, it handles the pool as one continuous environment, which is where most systems tend to fall short.
In practical terms, this shifts the experience from managing individual cleaning tasks to relying on a system that delivers complete coverage in one run. That reduction in manual effort is what makes it a smarter upgrade, and also what allows it to stand out as a more considered purchase for homeowners looking to simplify how their pool is maintained.
Designed to handle the areas most systems miss
In many pools, the challenge is not cleaning the obvious surfaces but reaching the areas that are easy to skip. Shallow platforms, tanning ledges, and multi-level sections often sit outside the effective range of standard robotic cleaners, which leaves parts of the pool inconsistent even after a full cycle.
The Sora 70 addresses this through its dual SonicSense ultrasonic sensors, which allow it to navigate shallow-water zones as low as 8 inches. This enables it to move across varied pool layouts without breaking the cleaning path, maintaining continuity from surface to floor.
That consistency removes the need for manual correction after each cycle, which is where most of the effort tends to go. For users looking for reliable cleaning that holds up through regular use, this is where the system begins to justify itself not just as an upgrade, but as something that delivers ongoing value over time.

JetPulse turns surface cleaning into an active process
Surface debris is one of the most persistent issues in pool maintenance, especially during summer use when leaves, dust, and particles return quickly. Most robotic systems rely on passive movement, collecting debris only when it drifts into range, which often requires multiple cycles to achieve visible results.
The Sora 70 takes a more active approach through its JetPulse system. A twin-jet mechanism generates directed water flow that pulls floating debris toward the intake, allowing it to be captured earlier in the cycle rather than after repeated passes. This shortens the time between cleaning and usability, which matters more during periods of frequent use. Instead of waiting for the pool to settle, it stays ready with fewer interruptions, supporting a setup that is easier to maintain without repeated intervention.
HydroBalance maintains consistent suction across the entire cycle
In many robotic cleaners, suction performance drops as the cleaning cycle progresses, which leads to uneven results and often requires additional runs to fully clear the pool. That inconsistency becomes more noticeable during regular use, when debris accumulates quickly and cleaning needs to be reliable rather than repeated.
The Sora 70’s HydroBalance system is designed to maintain a steady flow throughout the cycle. A center-mounted pump creates a direct, low-resistance path, while a high-efficiency motor sustains 6,800 GPH suction without drop-off. The 6.7-inch intake reduces clogging, and the bottom-hugging design helps retain suction close to the surface being cleaned. This allows debris to be removed in a single pass, reducing the need for additional cleaning cycles and making the system easier to depend on as part of a regular pool routine.

Filtration that supports both routine cleaning and higher-precision results
Alongside debris removal, the Sora 70 is built to handle the difference between visible cleaning and actual water clarity. A 6L, 150-micron debris basket captures leaves, insects, and larger particles during everyday use, allowing longer cycles without frequent emptying and keeping routine maintenance consistent.
When finer particles become more noticeable, particularly during periods of frequent use, an optional 3-micron ultra-fine filter captures dust, pollen, and algae spores that are not always visible during standard cleaning cycles.
By maintaining the same cleaning process while improving the level of filtration, the system avoids adding extra steps while delivering a more refined result. That consistency becomes part of its long-term value, particularly for homeowners who want a setup that continues to perform without added effort, and for those considering a more considered purchase that improves how the pool is maintained over time.
Retrieval that does not interrupt the process

Retrieval remains one of the most inconvenient parts of robotic cleaning. The process often requires manual handling at the end of each cycle, which breaks the sense of automation. The Sora 70 addresses this through Smart Water-Surface Parking and One-Touch App Retrieval. At the end of a cycle, it rises to the surface and moves toward the pool edge, where it can be accessed without additional effort.
The SmartDrain system releases excess water before lifting, reducing weight and making handling easier. This keeps the experience consistent from start to finish, without reintroducing effort at the final step, which is often where automation tends to fall apart.

Built for longer use, not just shorter cycles
Pool cleaning needs to keep up with usage, especially during summer when the pool is used more frequently. The Sora 70 is powered by a 10,000 mAh battery that supports up to seven hours of surface cleaning or five hours of full-pool cleaning, allowing it to cover up to 3,230 square feet in a single cycle.
Its cordless design removes the need for cable management, improving ease of use in active outdoor environments. This makes it easier to treat as part of a regular setup rather than a task that needs planning, which is where most systems start to feel limiting.
A shift that fits how pools are used through the season
Pool usage changes once the season is in full swing, with expectations moving beyond basic cleaning toward maintaining a space that stays ready without repeated attention. Bringing surface cleaning, walls, and the pool floor into a single system allows the Sora 70 to remove the need for managing separate steps, keeping the overall setup consistent even during periods of regular use without adding to the workload.
That difference becomes more relevant when the decision moves from solving an immediate problem to choosing a system that continues to deliver over time. For homeowners upgrading an outdoor space, the Sora 70 works as a high-value addition that improves how the pool is used without adding complexity. It also translates naturally into a premium, practical gift for pool owners or new homeowners, where the value comes from reducing a recurring task rather than introducing another one.

With Anniversary pricing from May 9 to 25, where it is available at $1,149, down from $1,499, the timing aligns with peak pool use. The shift toward less manual work and a more reliable setup becomes easier to act on, making it a relevant upgrade for the season as well as a considered purchase that continues to deliver beyond it.
Sora 30: a smart upgrade for consistent everyday cleaning
Building on the approach established by Beatbot’s Sora 70, the Sora 30 focuses on the parts of pool cleaning that define everyday use, delivering consistent results without moving into full 4-in-1 automation. It is designed for users who want dependable cordless pool cleaning that reduces manual effort while keeping the system simple to operate.
Its 3-in-1 cleaning across floor, walls, and waterline ensures routine maintenance is handled in a single cycle, with dual roller brushes supporting stable wall climbing and consistent contact across surfaces. The filtration system captures both larger debris and finer particles within the same pass, helping avoid repeat runs, while a runtime of up to five hours allows most residential pools to be cleaned without interruption.
Coverage extends to shallow zones such as steps and ledges, and smart surface parking brings the unit to an accessible point for retrieval, with the fully cordless design removing cable management altogether and making repeated use easier to manage over time.

As part of Beatbot’s Anniversary offer from May 9 to 25, the Sora 30 is available at $699, down from $999, positioning it as a clear step up from entry-level cordless pool cleaning. It works both as a smart upgrade for everyday use and as a practical, high-value gift for pool owners or new homeowners, delivering less work, more pool time, and a setup that holds up through regular use.
AquaSense X: a premium system for low-intervention pool care
Extending beyond the Sora series, Beatbot’s AquaSense X is designed for users who want pool cleaning to operate with minimal involvement, moving from consistent maintenance into a more automated, system-led approach.
It brings complete, all-zone coverage into a system built around advanced pool robotics, combining floor, walls, waterline, and surface cleaning with filtration and water clarification. Automated debris handling reduces the need for manual emptying, while intelligent navigation ensures consistent coverage across the entire pool without requiring supervision, shifting the experience from managing cleaning cycles to relying on a system that runs with minimal input. This makes it particularly relevant for larger pools or setups that see frequent use, where consistency and reduced intervention matter more than isolated cleaning performance.
As part of Beatbot’s Anniversary offer from May 9 to 25, the AquaSense X is available at $3,999, down from $4,250, positioning it as a flagship upgrade within advanced pool robotics. It also works as a premium, high-value gift for homeowners investing in outdoor spaces, delivering less work, more pool time, and a system that continues to perform without constant attention.

AquaSense 2 Ultra: AI-powered cleaning for complex pool environments
Positioned within the premium segment, the AquaSense 2 Ultra introduces HybridSense AI-powered mapping, enabling precise navigation, obstacle detection, and adaptive path planning across complex pool layouts. Its 5-in-1 cleaning system covers surface, floor, walls, waterline, and water purification, while HybridSense AI mapping helps reduce cleaning time by up to 50% through more efficient coverage. ClearWater natural clarification improves water clarity alongside debris removal, and side brushes enhance surface cleaning performance, ensuring that both visible and fine particles are addressed within the same cycle.
Adaptive path planning allows it to navigate multi-level platforms and irregular pool shapes more effectively, while remote control functionality provides flexibility when needed. Once cleaning is complete, the system returns to the pool edge automatically for easy retrieval without manual handling.
Available at $2,649, with $501 off as part of Beatbot’s Anniversary offer from May 9 to 25, the AquaSense 2 Ultra stands out as a compelling premium upgrade for users looking to step into AI-driven pool cleaning. It balances reduced cleaning time, complete coverage, and advanced automation, making it easier to maintain a high-quality pool setup with less ongoing effort.
A more complete way to approach pool care this season
This lineup works because each system is aligned to a clear level of effort reduction. The Sora 70 brings full coverage into a single system. The Sora 30 simplifies everyday cleaning into a more consistent routine. The AquaSense range extends that further into automation and intelligent control.

With the Anniversary Campaign running from May 9 to 25, the decision shifts from comparing features to choosing how much of the process to remove. Whether it is replacing manual cleaning, consolidating multiple tools, or moving toward a more automated setup, the current pricing makes that shift easier to act on now.
For pool owners preparing for the season, or for those looking at a more meaningful, high-value gift, this is a moment where upgrading becomes a practical decision. Whether it is about reducing ongoing effort or making the pool easier to use day to day, the Sora 70 aligns with a simple outcome that defines summer use at its best, less work and more time in the water.
There are probably a few old Fire TV Sticks still plugged into TVs across the country, collecting dust and loading just slowly enough to make you wonder whether it’s time to replace them. According to a proposed class-action suit filed in California, that sluggishness isn’t an accident. The suit alleges that Amazon deliberately ended software support for first- and second-generation Fire TV Sticks without adequately disclosing its plans to do so, effectively pushing functional hardware into early obsolescence and steering frustrated owners toward buying newer models.
The plaintiff named in the suit, Bill Merewhuader, filed in the Superior Court of Los Angeles County, said he purchased two second-generation Fire TV Stick devices from Best Buy in 2018, four years after the company debuted its first Fire TV Stick. Merewhuader said that a few years later, he experienced slower streaming speeds, difficulty navigating menus and long load times.
He eventually was unable to use the device. He purchased new Fire TV Sticks in 2024, according to the filing.

Merewhuader says in the complaint that Amazon intentionally made older devices perform poorly to spur hardware upgrades and “bricked” Fire TV devices “before the expiration of their useful life.”
A representative for Amazon did not immediately respond to a request for comment. Lawyers for the plaintiff said they had no further comment beyond the legal complaint.
Streaming devices are getting older
Popular streaming devices from big tech companies have been around for nearly two decades. Apple debuted AppleTV in 2007, and Roku followed the next year. Google’s Chromecast, which evolved streaming devices from set-top boxes to plug-in dongles, launched in 2013. Amazon followed up the next year with its Fire TV box and plug-in stick, released later in 2014.
As earlier generations of devices from these tech companies age, it’s common for them to lose functionality, as they can’t run newer apps or access certain features. For instance, Apple’s first Apple TV box is all but inoperable today and was eventually replaced with Apple TV 4K streaming boxes.
The filing partly hinges on allegations that Amazon did not inform buyers that Fire TV Stick devices would lose functionality or become inoperable over time, and that the performance of early devices did not match the promises Amazon made in its marketing.
The proposed class action would be open to anyone who resides in the US and who still owns a first- or second-generation Fire TV Stick as of Jan. 1, 2023, or April 1, 2023, respectively.
Password resets are often the first response to a suspected compromise. It makes sense; resetting credentials is a quick way to cut off an attacker’s most obvious path back in.
However, that doesn’t always completely solve the issue. In both Active Directory (AD) and hybrid Entra ID environments, password changes do not immediately invalidate the old credential across every authentication path.
Even a short window is an opportunity that potentially allows attackers to maintain access or re-establish a foothold.
For security architects and IT administrators, this gap has real implications during incident response.

The password reset gap
Windows systems cache password hashes locally to support offline logon. If a device hasn’t reconnected to the domain, it may still hold the previous credential in a usable form. In hybrid environments, there can also be a short delay before the new password syncs to Entra ID.
This means there are three possible states created after a password reset:
1. The user has logged in with the new credential while connected to AD. The cached credential store updates, invalidating the old hash.
2. The user has not logged in to a particular machine since the reset. The old cached credential may still be usable for certain authentication attempts.
Advertisement
3. In hybrid deployments, the password has been reset in AD but the new hash has not yet synchronized to Entra ID. The old password may still authenticate during the password hash synchronization interval.
Verizon’s Data Breach Investigation Report found stolen credentials are involved in 44.7% of breaches.
Effortlessly secure Active Directory with compliant password policies, blocking 4+ billion compromised passwords, boosting security, and slashing support hassles!
Attackers take advantage of cached password hashes with methods like pass-the-hash, where the hash itself is used instead of the plaintext password. If that hash was captured before the reset, changing the password doesn’t immediately invalidate it everywhere.
Limiting that exposure is crucial to defending AD environments. Solutions like Specops uReset enable secure self-service password resets by enforcing end-user ID verification to reduce the risk of reset abuse.
Advertisement
When combined with the Specops Client, uReset can update the local cached credential store immediately on the device where the reset is performed, closing the window where the old hash remains usable on that endpoint.
This doesn’t remove identity drift entirely, but it does reduce exposure at the network edge, where corporate laptops and remote systems are frequently targeted.
Specops uReset
Active sessions
AD authentication is primarily handled through Kerberos tickets, which are valid for a set period of time. If a user or attacker already has a valid ticket, they can continue accessing resources without re-entering a password.
That means an attacker with an active session remains authenticated even after the password has been changed. In some cases, that window is long enough to establish additional persistence or move laterally.
Unless sessions are explicitly invalidated, through logoff, reboot, or ticket purging, access can continue well beyond the reset itself.
Advertisement
Service accounts
Unlike user accounts, service accounts tend to have long-lived passwords, with elevated privileges tied to critical systems. Attackers can expose those credentials through techniques like Kerberoasting or discover them when moving laterally through a network.
Because these accounts are tied to running services, they’re less likely to be reset quickly, especially if there’s a risk of disruption. That makes them a reliable fallback for attackers after an initial access point is closed.
Ticket attacks
As mentioned above, in environments using the Kerberos authentication protocol, access is controlled through tickets rather than repeated password checks. If an attacker can forge those tickets, they don’t need valid credentials at all.
A Golden Ticket attack, made possible by compromising the Kerberos Ticket Granting Ticket account, allows attackers to create valid ticket-granting tickets for any user in the domain. Silver Tickets are more targeted, granting access to specific services without contacting a domain controller.
Advertisement
In both cases, these attacks effectively bypass password changes. Resetting user passwords won’t invalidate forged tickets, and access can continue until the underlying issue is addressed.
Permissions
AD is heavily driven by Access Control Lists (ACLs). If an attacker grants a compromised account (or a new one they control) rights like resetting passwords for other users, they’ve effectively created a backdoor. Even if the original password is changed, those permissions remain.
Furthermore, accounts protected by AdminSDHolder (like Domain Admins) inherit permissions from a specific template. Attackers who modify the ACL on the AdminSDHolder object can ensure their permissions are re-applied every hour by SDProp.
How to ensure attackers are removed
The time between a password reset and it synching across AD and Entra ID is small, typically just a few minutes, which severely limits the opportunity attackers have to exploit the gap. Forcing more frequent synchronizations is also possible, for instance turning on AD Change Notification or manually initiating a Sync to the Entra ID tenant.
Advertisement
However, the gap still exists, and by the time an account compromise is discovered, attackers may have been able to establish additional footholds. If password resets aren’t enough on their own, defenders need to look at fully closing off access.
That starts with invalidating anything already in play. Active sessions should be terminated, and Kerberos tickets cleared by forcing logoffs or reboots on affected systems. For more serious compromises, resetting the KRBTGT account (twice) is often necessary to invalidate forged tickets.
Next comes credential hygiene beyond standard user accounts. Service account passwords should be rotated, especially those with elevated privileges, and any cached credentials on endpoints should be cleared as systems reconnect.
Just as important is reviewing what’s changed in the directory itself. That means auditing:
Advertisement
Group memberships
Delegated rights and ACLs
Privileged accounts and roles
Look for anything that could allow access to be re-established without relying on a password.
For serious breaches, there isn’t a single step that guarantees eviction. It’s a combination of cutting off sessions, rotating the right credentials, and verifying that no hidden access paths remain.
