Huge backdoor discovered that could compromise SSH logins on Linux

On Friday March 29, Microsoft employee Andres Freund shared that he had found odd symptoms in the xz package on Debian installations. Freund noticed that ssh login was requiring a lot of CPU and decided to investigate leading to the discovery.

The vulnerability has received the maximum security ratings with a CVS score of 10 and a Red Hat Product Security critical impact rating.

Red Hat assigned the issue CVE-2024-3094 but based on the severity and a previous major bug being named Heartbleed, the community has cheekily named the vulnerability a more vulgar name and inverted the Heartbleed logo.

Luckily the vulnerability has been caught early

Red Hat wrote: "Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code. This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library."

The malicious injection can be found only in the tarball download package of xz versions 5.6.0 and 5.6.1 libraries. The Git distribution does not include the M4 Macro that triggers the code. The second-stage artifacts are present in the Git repository for the injection during the build time, if the malicious M4 macro is present. Without the merge into the build, the 2nd-stage file is innocuous.

You are recommended to check for xz version 5.6.0 or 5.6.1 in the following distributions and downgrade to 5.4.6. If you cannot you should disable public facing SSH servers.

No joke, Gmail is 20 and we're probably better for it

Gmail, the email service that almost started out as a joke but rose to become a dominant player in the space, is exactly 20 years old on April 1.

It is for most of us, as hard to imagine a world without Gmail as it is for us to search without Google. But Gmail was a latecomer to the email game, arriving decades after we started using computers to deliver electronic messages to third-party providers who would, like the old-school post office, sort and send them along to their proper digital destination. It was well after MSMail and ccMail but early enough that we still demanded a hyphen between “e” and “mail.”

Ever the cheeky upstart (despite by then being the most-used search engine), Google launched Gmail on April Fool’s Day to mostly widespread confusion. At PCMag, where I worked at the time, we admitted that “Google's release included language which sounded like a ruse” and no one was quite sure if the search giant was serious about entering the crowded email space. Part of that had to do with the quite limited availability of the platform.

Google was among the first Internet companies to offer invite-only access to a new service. It was a brilliant bit of marketing but also had a more practical purpose. Google had struggled to launch Gmail and was still learning when it moved into public beta. Open access would’ve overwhelmed the system, forcing untold crashes, possibly un-delivered mail, and probably made it almost impossible to learn about what people wanted, needed, and used most often in the IMAP mail platform (there was no POP3 support at launch).

Welcome to the party, pal

On April 22, 2004, almost four weeks after the launch, I got access. I still have the welcome message, that told me I was “one of the very first people to use Gmail,” and thanked me for “agreeing to test Gmail.” The email described some of the key differences, like “searching instead of filing.” Gmail didn’t use folders, a time-honored way of organizing email, and instead focused on labels and conversations. To this day, the concept of folders in Gmail is foreign and I’m not sure I have ever loved the more amorphous “labels”.

It had some advanced features like filters and address autocomplete. And, of course, it came with 1GB of storage, an amount unheard of at the time for a free email service, which now seems woefully inadequate. Google's pitch at the time was that we could stop wasting time deleting emails and save everything. I think I over-committed to this concept.

While Gmail didn’t have pop-up or banner ads (thank God), there were text-based ads in a column to the right (Gmail ads now mostly live under the “Promotions” tab). This turned out to be Gmail’s most controversial “innovation”. To provide contextual ads, Google would have to “read” the contents of your email. That sounded like an insane privacy violation, and I wrote about the concern right before I gained access. I reminded readers that computers, at least back then, didn’t really “read” anything. They had neither the eyes nor the consciousness to understand the context. Google was, of course, already anonymizing the data and delivering contextual ads without delivering your private bits to third parties. I also noted that, without those ads, we might not get all that, at the time, free storage. It’s worth noting that those early concerns did nothing to hinder Gmail’s growth.

Along with access to Gmail came some invites that I could dole out. They arrived in small bunches, and I would give them to co-workers, colleagues, and friends. Some people who knew I had a Gmail account sent me emails and AOL messages pleading for access. Whenever I gave someone access, Gmail would notify me of when they signed up and created their new Gmail address “so we could stay in touch with Gmail!” While not a social network, Google was aware of the inherently social nature of email. Keeping newbies connected was how it built that network and generated just enough FOMO to keep the service growing.

All the information

Google took a risk when it launched Gmail, and it knew it. In the original FAQ, Google had to explain why a Search company would launch an email service:

“Why is Google offering email? I thought you were a search company.

Google's mission is to organize the world's information and make it universally useful and accessible. For many people, email contains valuable information that can be difficult to retrieve. We believe we can help with that.”

It was further evidence that Google’s strategic aim was never just about search results, it was about information, yours, mine, and everyone else’s. Google wanted to organize the world’s information no matter the form, from search results, to mail, to video and images, and location. That quest never stops and not everyone is happy about it.

Even so, it’s worth celebrating Gmail, an online service that entered an entrenched market and ultimately remade it in its image. It never was and will likely never be a joke.

PSA: you can still get a Google Pixel 8 for a ridiculously low price right now

This week has arguably the best set of Google Pixel 8 deals we've ever seen on both the standard Pixel 8 and the more premium Pixel 8 Pro.

For example, at Amazon you can get the 8 for a rock-bottom price of just $499 (was $699) and the Pro for just $749 (was $999). Both of these are record-low prices at the retailer and a superb option if you're looking to bag an unlocked device without the usual carrier plan.

Even cheaper still is Mint Mobile's massive price cuts of up to $300 this week, which get you to the standard Pixel 8 for just $399 and the Pixel 8 Pro for $720 alongside a six-month plan. While you'll still need to buy a plan to be eligible for this particular promotion, Mint's also throwing in six months of service for free to sweeten the deal for new customers. 

Finally, for those who are willing to go with a big carrier, we'd highly recommend Verizon's current deal, which offers the standard Pixel 8 for free alongside a new line on an unlimited data plan. The carrier is also throwing in a 65-inch 4K TV worth $600 alongside the device right now, which is one of the best freebies you'll find anywhere on the carrier's site - you will still have to pay for that pricey unlimited plan, though.

You can read more about these Google Pixel 8 deals just down below or head on over to our main cell phone deals page for options on other devices.

Hey Apple, we need a new iPhone SE sooner than later

I recently wrote about how the iPhone 13 is a great phone to buy if you can’t afford an iPhone 15, and I stand by that. I still feel we’re missing a solid budget phone option from Apple. 

Sure, we have the 2022 iPhone SE, but it was a tad underwhelming. It has a design that’s positively ancient in phone terms, a 60Hz display, a single rear camera, and lacks a vast array of features. Compare the iPhone SE to some of the best cheap phones from Google, Samsung and OnePlus, and it looks almost like Apple is chancing its hand at pushing old leftover tech that’s had a simple reheat in a microwave oven before being punted out to consumers. 

The problem here is that unless you go down the pre-owned route, there’s no other option for a budget iPhone. 

The rumors so far hint at an iPhone SE 4 being on the horizon, and they seem to promise a fresher design that borrows from the likes of the iPhone 14 and iPhone 15. That’s good news, as both phones have a pleasing look and an aesthetic language that harks back to the Jony Ive era of Apple’s industrial design. 

However, when it comes to a release window things are unclear – we don’t know whether to expect an iPhone SE this year or in 2025. For what it’s worth I hope Apple comes up with a new SE this year. 

Cheaper, cheerful

We’re living in a time when the cost of living has skyrocketed and smartphones show no signs of being cheaper. At the same time, phones don't offer great bang for the buck like they once did, especially if you’re stuck in the Apple ecosystem.

As an iPhone 15 Pro Max user, I’m a big advocate for Apple’s Pro iPhones, with the current models offering a suite of upgrades over the predecessors that place them among the best phones overall. But you need a healthy chunk of change to be able to buy them; even on a carrier contract, Apple’s flagship phones are hardly cheap.

The more affordable iPhone 15 and iPhone 15 Plus are both very good phones, but for their respective prices – with a 60Hz display and cameras that, while impressive, aren’t pushing the envelope – the phones aren’t inspiring. Comparatively, around the same money will get you a Samsung Galaxy S24 with its trio of rear cameras, 120Hz display, and a whole host of generative AI features.

Going by the iPhone 16 rumors so far – and admittedly, it’s early days on that front – Apple’s next-generation smartphones won’t be a huge evolution over their predecessors. One can expect a boost in performance, which is almost moot as the past few generations of iPhones have more than enough power. 

We can also expect a dose of generative AI features for at least the iPhone 16 Pro models. Otherwise, I doubt there’ll be much to separate the next-gen iPhones from today’s models. Nor do I expect the prices to drop, either.

With that in mind, I want a new budget iPhone that offers a modern design and features would be very much welcome, as we likely wait for the iPhone 17 to bring in truly novel upgrades.

Some say Apple fans will swallow whatever’s presented to them. That may have been true in the past, especially when phones could jump a decent amount each generation in terms of performance, cameras and features. 

Today, consumers are more tech-savvy and the best Android phones are so well-equipped that one doesn't need to remain stuck in Apple’s ecosystem. As such, high prices and a ‘meh’ budget option could drive people to the Android camp.

Of course, Apple phones still sell like crazy, with various data showing how the iPhone 15 models have sold better than their predecessors. So it’s not like Apple’s fortunes are going to suddenly wane.

But I feel there's an opportunity in the budget phone arena that Apple could tap. A capable but affordable iPhone could see more people sign up to services like Apple Arcade, Apple Music Plus and Apple News Plus, potentially putting the money saved on phone hardware into Apple’s growing services suite.

Apple is also a mover and a shaker when it comes to phone tech, so it could help shake-up the status quo with affordable phones and help set a standard for others to follow (though the Google Pixel a-series do that well) or inject some refreshed non-Android competition into the market.

Perhaps this is all wishful thinking on my part, as Apple tends to do what Apple wants and to hell with the general consumers. But I’m still going to cross my metaphorical fingers for a new iPhone SE this year that embraces Apple’s latest design language and doesn't skimp on features. If that doesn't happen, then I’ll be looking for the rumored Google Pixel 8a to be the budget phone of 2024.

Quordle FAQs: Everything you need to know

What is Quordle?

Where Wordle challenges you to guess a new five-letter word each day, Quordle presents you with four puzzles to solve. And rather than complete them in turn, you do so simultaneously. You get nine guesses, rather than the six for Wordle, but the rules are otherwise very similar. 

It's played online via the Quordle website and you can also get to it via the Merriam-Webster site, after the dictionary purchased Quordle last year

As with Wordle, the answers are the same for every player each day, meaning that you're competing against the rest of the world. And also as with Wordle, the puzzle resets at midnight so you have a fresh challenge each day.

The website also includes a practice mode - which I definitely recommend using before attempting the game proper! - and there are daily stats including a streak count. You also get Quordle Achievements - specific badges for winning a game in a certain number of turns, playing lots of times, or guessing particularly hard words.

Oh, and it's difficult. Really difficult.

What are the Quordle rules?

The rules of Quordle are almost identical to those of Wordle.

1. Letters that are in the answer and in the right place turn green.

2. Letters that are in the answer but in the wrong place turn yellow. 

3. Letters that are not in the answer turn gray…

4. …BUT the word you guess appears in all quadrants of the puzzle at the same time, so an A could turn green in one square, yellow in another and gray in the final two. 

5. Answers are never plural.

6. Letters can appear more than once. So if your guess includes two of one letter, they may both turn yellow, both turn green, or one could be yellow and the other green.

7. Each guess must be a valid word in Quordle's dictionary. You can't guess ABCDE, for instance.

8. You do not have to include correct letters in subsequent guesses and there is no equivalent of Wordle's Hard mode.

9. You have nine guesses to find the Quordle answers.

10. You must complete the daily Quordle before midnight in your timezone.

What is a good Quordle strategy?

Quordle needs to be approached in a different way to Wordle. With four puzzles to solve in nine guesses, you can't blindly throw letters at it and expect to win - you'll stand a far better chance if you think strategically.

That's the case in Wordle too, of course, but it's even more important in Quordle.

There are two key things to remember. 

1. Use several starting words

Firstly, you won't want just a single starting word, but almost certainly two or three starting words. 

The first of these should probably be one of the best Wordle starting words, because the same things that make them work well will apply here too. But after that, you should select another word or possibly two that use up lots more of the most common consonants and that include any remaining vowels.

For instance, I currently use STARE > DOILY > PUNCH. Between them, these three words use 15 of the 26 letters in the alphabet including all five vowels, Y, and nine of the most common consonants (S, T, R, D, L, P, N, C and H). There are plenty of other options - you might want to get an M, B, F or G in there instead of the H, maybe - but something like that should do the trick.

If all goes well, that will give you a good lead on what one or sometimes two of the answers might be. If not, well good luck!

2. Narrow things down

Secondly, if you're faced with a word where the answer might easily be one of several options - for instance -ATCH, where it could be MATCH, BATCH, LATCH, CATCH, WATCH, HATCH or PATCH - you'll definitely want to guess a word that would narrow down those options. 

In Wordle, you can instead try several of those in succession and hope one is right, assuming you have enough guesses left. It's risky, but will sometimes work. Plus, it's the only option in Hard mode. But in Quordle, this will almost certainly result in a failure - you simply don't have enough guesses.

In the scenario above, CLAMP would be a great guess, as it could point the way to four of the seven words in one go.

You can get a MacBook Air for $699 and a Dell XPS 13 for just $599 - is this the best time ever for laptop buyers?

Both the Apple MacBook Air and the Dell XPS 13 are outstandingly good premium laptops - and both are on sale for some of the lowest prices we've ever seen currently.

For example, Walmart currently has the Apple MacBook Air M1 for just $699, which isn't just a record-low price but a whopping $300 cheaper than the original retail price. Granted, it's an older 2020 model, but this is a superb deal for a machine that's still more than capable for most users in 2024.

Over at the official Dell store, you can pick up a 2022 XPS 13 for just $599 - which is almost unbelievable considering how premium this Windows laptop is. With super-thin display bezels and a gorgeous aluminum chassis, this model is a great buy right now - just know that it's the configuration with the 256GB SSD (like the M1 MacBook above).

Two outstanding good laptop deals

Apple MacBook Air M1: was $999 now $699 at Walmart
Processor: 
Apple M1
RAM: 8GB
SSD: 256GB

The 2020 MacBook Air is getting on a bit now but it's still one of our favorite laptops ever. Inside, you get a capable M1 chipset that's still great for everyday tasks like web browsing, streaming content, or most work-from-home applications. Yeah, the bezels are a little thicker now but it's a great laptop - and one that is now sitting at a rock-bottom record-low price thanks to Walmart's latest deal. View Deal

Dell XPS 13 laptop: was $799 now $599 at Dell
Processor: Intel Core i5-1230U
RAM: 8GB
SSD: 256GB

The cheapest Dell XPS 13 you can buy right now is a third of the price of the fancy new models. In fact, at $599, this deal is the cheapest XPS 13 we've ever seen. There are some trade-offs, of course, in the fact that you get a relatively small 256GB SSD and an older 12th gen Intel Core i5, but this machine still features a premium high-end design. If you're just looking for a Windows machine to cover the basics then this one is a great choice. View Deal

But, which is the better deal right now?

Apple MacBook Air (M1,2020)

(Image credit: Future)

Windows vs MacOS - it's a battleground that's been around for as long as computers have been a thing. In 2024, both eco-systems offer incredible app support, superb interfaces, and plenty of headroom for upgrades down the line. So, realistically, it comes down to personal preference in regard to which is best for you.

That said, we'd single out the MacBook Air M1 as an incredible bang-for-the-buck option for most people right now. Apple products haven't traditionally been known for their value, but this M1 MacBook is barely as expensive as some refurbished and second-hand models right now. It's quite simply a ton of laptop for the money.

Not only that, but the M1 chipset inside the MacBook Air is incredibly power efficient, which lends not only to excellent battery life but a unique fan-less design that's almost silent in operation. Performance-wise, there won't be much between the two laptops, but the Air will provide better battery life overall.

With all that said, both of these laptops are fantastic, powerful, and, above all, cheap. If your budget is around $600 to $700, you can't go wrong with either choice.

Black Friday-beating deals: save up to $600 on RTX 4070 and 4060 gaming laptops

March isn't traditionally known for its gaming laptop deals, but there are some absolutely outstanding options on the market right now. Dell and Best Buy, in particular, are offering massive price cuts of up to $600 on some of our favorite gaming laptops. 

Our top choice for those on a budget is this RTX 4060-equipped MSI Cyborg for $849 (was $1,099) at Best Buy - one of the cheapest machines we've ever seen to feature the powerful graphics card. Pound for pound, this machine is a great budget buy if you need something relatively powerful without breaking the bank.

For something with a little more oompth, consider this outstandingly cheap MSI Crosshair for $1,199 (was $1,399), which features an RTX 4070 graphics card, 16GB of RAM, and 1TB SSD. This machine isn't the cheapest out there right now but it's really great value considering the level of specs you're getting here.

And, for a premium gaming laptop where looks are as important as performance, consider the excellent Asus Zephyrus G14 for $999 (was $1,599) at Best Buy or the Alienware M16 for $1,499 (was $2,199) at Dell. Both these choices feature superb components for the price - but also an eye-catching design that sets them apart from the usual cheaper models. 

You can read more about our choices just down below, or head on over to our gaming laptop deals page for even more recommendations.

Processor: Intel Core i7-12650H

I've seen this MSI Cyborg on sale for $799 before over Black Friday, but this deal at Best Buy is almost as good. For the money, this mid-range machine is offering almost unbeatable bang for the buck with its RTX 4060 and Core i7 chipset. Put together, you're getting great performance here, well under $900 - more than enough to max out the graphical settings at 1080p resolutions.View Deal

Processor: AMD Ryzen 9-7940HS
Graphics card: RTX 4060
RAM: 16GB
SSD: 512GB

Speaking of amazing gaming laptop deals on mid-range machines, here's a record-low price on one of our favorite laptops ever. This Asus Zephyrus G14 is a slightly older model, but it's still a great buy if you'd like a smaller 14-inch laptop. This particular configuration is packed in an RTX 4060 and Ryzen 9, meaning it's capable of outputting some serious performance despite its diminutive size. View Deal

MSI Crosshair 16 gaming laptop: was $1,599 now $1,199 at Best Buy
Processor: Intel Core i7-13620H
Graphics card: RTX 4070

Need a more powerful machine? This MSI Crosshair is easily one of the cheapest gaming laptop deals on the market right now, and it features a speedy RTX 4070 graphics card. This GPU, combined with a 13th-generation Intel Core i7, means this MSI is an exceptionally capable gaming laptop. While pricey compared to some of the RTX 4060 options on our list, this one is just as good value.View Deal

Alienware M16 gaming laptop: was $2,199 now $1,499 at Dell
Processor: Intel Core i7-13700HX
Graphics card: RTX 4070
RAM: 32GB
SSD: 1TB

Last year's Alienware M16 is a great buy if you don't mind getting a slightly older model - especially with this huge price cut courtesy of the Dell TechFest sale.

An ancient Linux flaw might be opening up users to dangerous cyberattacks

Many versions of Linux may be vulnerable to a flaw that allowed hackers to steal passwords, or change the contents of their clipboard.

The vulnerability, however, comes with a major caveat that makes exploitations somewhat unlikely (or at least heavily limited).

Cybersecurity researcher Skyler Ferrante recently discovered an “improper neutralization of escape sequences in wall” vulnerability, a flaw impacting the “wall” command. This command is usually used to broadcast messages to the terminals of all users logged to the same system.

WallEscape

With escape sequences not being properly filtered when processing input through command line arguments, a threat actor could, theoretically, launch a prompt to all connected users and have them type in their administrator password. Escape sequences could also be used to change the clipboard of a target user, although this method may not work with all terminal emulators.

The vulnerability is tracked as CVE-2024-28085, and dubbed WallEscape. It was fixed in Linux version 2.40, released in March 2024, but that means it has been present in Linux versions for the past 11 years.

While a proof-of-concept (PoC) for the vulnerability exists, and a practical application could occur, multiple factors need to align, first. For example, the attacker needs to have physical access to a Linux server, to which multiple other potential victims are already connected through the terminal. If you’re still worried about your Linux server being targeted, there is a solution. Linux released an upgrade to linux-utils v.2.40, which patches the vulnerability. 

Usually, these updates are available through the LInux distribution’s standard update channel, so keep an eye out. Furthermore, system administrators can fix the issue by removing the setgid permission from the “wall” command, or by disabling the message broadcast functionality using the “mesg” command to set its flag to “n”.

SMBs believe AI is going to give them the edge when it comes to success

Small business owners are increasingly turning to artificial intelligence to gain a competitive advantage in the market, new research has claimed.

A GoDaddy study of over 500 US entrepreneurs found a growing confidence in the power of generative AI tools to drive business success.

The findings indicate a positive shift in attitude towards AI among small and medium-sized businesses. Three in four believe that GenAI will give them an edge over similar-sized competitors. More than two-thirds (68%) also see AI as enabling them to compete better with larger enterprises.

GenAI is helping SMBs

Nearly three-quarters (73%) said that they’ve already experimented with the technology, and more than a quarter (26%) already use AI for business purposes – up from 11% in the year before.

Generative AI really took off back in November 2022 when ChatGPT hit public preview, but SMBs are now expanding their use cases beyond simple content generation. More than two in five (44%) now use AI to enhance sales performance – twice as many as in 2023.

Amy Jennette, Senior Director of Marketing at GoDaddy, commented on the trend, stating: “We’re at the beginning of the AI revolution and small businesses are already taking advantage of the technology, which is really unprecedented.”

Despite initial concerns about AI potentially replacing human jobs, the survey found very low levels of concern among SMBs – only one in 10 believed that GenAI could outperform them in their roles, and the majority (89%) expressed confidence that AI would have a positive impact on their business.

Jennette also highlighted the tangible benefits of deploying AI across the SMB landscape, revealing that small businesses could save over $4,000 and 300 hours of work annually, underscoring the potential cost-saving benefits of productivity tools that use artificial intelligence.

Helldivers 2 adds Quasar Cannon and Heavy Machine Gun Stratagems to accidentally shoot your friends with

Co-op shooter Helldivers 2 is back with yet another update, this time adding two all-new Stratagems that seem specifically designed to help combat the brutal Automaton enemy type.

The official Helldivers 2 X / Twitter account confirmed these powerful weapons with a neat, lore-appropriate graphic that shows off the LAS-99 Quasar Cannon and the MG-101 Heavy Machine Gun. Both can be earned in-game and distributed to players on the battlefield by calling them in via their Stratagem loadout.

The post states that these Stratagems "are available now for use against the Automaton horde," implying that these powerful weapons are particularly effective against the deadly robotic faction.

For those not in the know, Stratagems are powerful items in Helldivers 2 that can seriously turn the tide of battle if used appropriately. They can come in the form of massive guns as seen above, air strikes, placeable turrets or even something as simple as an ammunition resupply. They require players to input a code with the directional buttons, adding a layer of intensity when enemy counts become particularly frightening on if you're playing on the higher difficulties.

It will be interesting to see existing Helldivers 2 players takes to these new weapons. The game does feature friendly fire which, as you'd expect, often leads to players (accidentally or otherwise) killing members of their team. No doubt this will also be the case with these two powerful Stratagem weapons.

Launching only last month on PlayStation 5 and PC, Helldivers 2 has a long life ahead of it if its immense popularity is anything to go by. If you're a regular player and keen to stay up to date on the multiplayer shooter's future, be sure to read up about the latest details on our dedicated Helldivers 2 update page.

256TB SSDs could land before 2026 with a surprisingly low price — but will most likely use a controversial and popular trick borrowed from tape technology

ScaleFlux has announced its latest SSD controller in what could be a significant step up for the company.

The SFX 5016, the successor to the SFX 3016, incorporates several design advancements, including an upgrade from PCIe 4.0 to PCIe 5.0, doubling the host interface speed and bandwidth.

The new controller has been designed to support a maximum storage capacity of up to 256TB, a volume which JB Baker, VP of Products at ScaleFlux believes can be achieved sooner than expected, by taking a leaf out of tape technology.

256TBe drives are coming

Reaching 256TB is a big aim for SSD makers, and one that has some challenging hurdles to overcome. For starters, the physical space, determined by the size and form factor of the SSD, dictates how many NAND components it can accommodate. The density of these components also plays a part, with higher densities providing more storage capacity. The SSD's overall capacity can be limited by the controller's ability to handle a certain number of NAND chips and manage them effectively. Additionally, SSDs maintain a "logical to physical map" to track each byte of data stored, typically in DRAM for consistent performance in enterprise SSDs. The amount of DRAM that can fit in the drive can further limit the maximum drive capacity.

For all of those reasons, we likely won’t see a 256TB physical capacity drive arrive until 2026 at the earliest, with pricing expected to come in at around $25,000 each. But there is a solution that’s closer to hand. Baker says a “256T effective through compression drive could arrive by 2025 and cost a fraction of the price."

While offering a 256TB SSD ahead of the competition, and at a lower price point, sounds great, the method of achieving this is not without controversy.

Transparent compression, a feature included in the SFX 5016 and carried forward from the SFX 3016, is a popular trick borrowed from tape technology that allows an SSD to store more data than its physical capacity by compressing it. As Baker explains “a 3.84TB SSD can store 7.68TB of 2:1 compressible data for 'effective capacity'. Storage array vendors pitch the 'TBe' -Terabyte effective - capacity based on achieving a certain data compression ratio.”

Although there’s no firm timescale for it, if Baker is right, it’s possible we'll start seeing the first 256TBe drives late next year.

Ray framework flaw exploited for hackers to breach servers

The Ray framework, an open source tool for AI and Python workload scaling, is vulnerable to half a dozen flaws that allow hackers to hijack the devices and steal sensitive data. 

This is according to cybersecurity researchers from Oligo, who published their findings on a new hacking campaign they dubbed “ShadowRay”. 

Apparently active since early September 2023, ShadowRay’s operators abused five distinct Ray vulnerabilities to target firms in education, cryptocurrency, biopharma, and other verticals.

"Shadow vulnerability"

Four of the vulnerabilities are tracked as CVE-2023-6019, CVE-2023-6020, CVE-2023-6021, and CVE-2023-48023, and Anyscale, Ray’s developer, fixed them. The fifth one, deemed a critical remote code execution (RCE) flaw by researchers, and tracked as CVE-2023-48022, was not fixed.

Anyscale argues that this was not a bug, but a feature: "The remaining CVE (CVE-2023-48022) - that Ray does not have authentication built in - is a long-standing design decision based on how Ray's security boundaries are drawn and consistent with Ray deployment best practices, though we intend to offer authentication in a future version as part of a defense-in-depth strategy," it said.

As per the developers, this RCE flaw can only be abused in deployments that go against Anyscale’s recommendations and don’t limit Ray’s use to a strictly controlled network environment.

Oligo, on the other hand, says that by disputing the CVE, Anyscale is leaving many developers in the dark on the potential holes. "We have observed instances of CVE-2023-48022 being actively exploited in the wild, making the disputed CVE a "shadow vulnerability"—a CVE that doesn't show up in static scans but can still lead to breaches and significant losses."

The researchers said they observed “hundreds” of publicly exposed Ray servers, compromised via this vulnerability. As a result, threat actors were stealing sensitive data such as AI models, production database credentials, and more. In some instances they were even installing cryptominers.

A new ZenHammer attack is targeting more AMD CPUs

The infamous Rowhammer DRAM attack can now be pulled off on some AMD CPUs as well, academic researchers from ETH Zurich have proved.

As reported by BleepingComputer, the researchers dubbed the attack ZenHammer, after cracking the complex, non-linear DRAM addressing functions in AMD platforms.

For the uninitiated, the Rowhammer DRAM attack revolves around changing data in Dynamic Random Access-Memory (DRAM), by repeatedly “hammering”, or accessing, specific rows of memory cells. Memory cells keep information as electric charges. These charges determine the value of the bits, which can either be a 0, or a 1. As the density of the memory cells in today’s chips is fairly big, “hammering” can alter the state in adjacent rows, or “flip” the bit. By flipping specific bits, the attackers can pull cryptographic keys, or other sensitive data, BleepingComputer explained.

Purely theoretical?

This means that AMD has joined Intel and ARM CPUs who were already known to be vulnerable to hammering attacks.

The researchers tested their theory on different platforms. For AMD Zen 2, they were successful 70% of the time. For AMD Zen 3, 60%. For AMD Zen 4, however, they were only successful 10% of the time, suggesting that “the changes in DDR5 such as improved Rowhammer mitigations, on-die error correction code (ECC), and a higher refresh rate (32 ms) make it harder to trigger bit flips."

While usually academic research is purely theoretical, the researchers said this attack could be pulled off in the real world, too. They simulated successful attacks targeting the system’s security, and manipulating page table entries for unauthorized memory access.

Those fearing ZenHammer, it’s important to stress that these types of attacks are quite difficult to pull off. What’s more, there are patches and mitigations. Earlier this week, AMD released a security advisory with mitigation options.

Google Search is rolling out its AI-generated answers – whether you want them or not

Google is reportedly experimenting with its search results and looking to add AI overviews for more users. Previously, the feature was being tested for people who had opted into the Google Search Generative Experience (SGE),  which would allow them to try Google’s latest innovations with generative AI. Google claims that this update will give users more information and context to users’ searches.

Users can sign up to try search features that Google is testing and looking to receive feedback on via Search Labs. The Google Search Experience that Google has been working on displays an AI-generated answer which would be followed by the usual search result listings we’re used to. The AI-generated answer would be pre-empted by a very explicit ‘Generative AI is experimental’ disclaimer, and would be indicated visually by being sectioned off with a differently-colored background. 

Google will also show citations for where its AI model would source its information to give you your answer. You could then follow those citations and check out the sources for yourself, continue your search with another query or by perusing the other results, or toggle the AI-generated answer with options that Google provided at the bottom of it.

The experiment is going outside the Search Labs

Search Engine Land reports that Google is expanding AI-generated answers to more users, even if they haven’t opted into the Search Labs program. A Google spokesperson told Search Engine Land that this is being trialed on a “subset of queries, on a small percentage of search traffic in the U.S.”

The experimental search experience was announced in a Google Keyword blog post in May 2023, encouraging users to embrace the newer AI-powered features of search. These include searching visually with Google Lens and using multiple modalities, meaning different types of data, namely using text and images, to make search queries. Google claims it’s making progress in the way we can search, and now will be able to answer queries that it claims weren’t possible to answer earlier. 

The spokesperson continued that Google wants “feedback from searchers who have not opted into SGE specifically,” to get a sense of users' impressions from a more general population of searchers.

A major twist to a classic - big risk, big reward?

I can see why Google is pushing hard for this. Microsoft is going ahead at full steam to inject its AI tools into multiple apps, including many beloved classic applications. Google is still very much in the AI race with its recent release of the generative AI model, Gemini

Right now, it still seems like a very limited run of testing, but I expect that Google will expand this to more and more users. Now, I’ve found generative AI answers useful, especially for longer queries with more context, and having the sources there is a huge plus. That said, I’ve used it probably only a handful of times so far in place of when I maybe would have used a search engine. The way that legacy search engines, particularly Google Search, currently display results has become the industry standard, and it's pretty clear and straightforward. 

A change like this would be a pretty considerable shakeup to the status quo, and some industry observers are already concerned that Google is being too persistent with its efforts to integrate AI into existing products like Google Search. This could also affect how news and media sites operate in a significant way, as they largely depend on traffic from Google Search results, which would likely end up much further down the page.

Changes to things that have become staples of our day-to-day lives are almost always controversial, but maybe the proof is in the pudding and Google might be right that this will be a preferable way to search. The only way to know is to test it, which it’s doing, but I would be wary of making it a default search results format. Perhaps it would be better for Google to make it an opt-in change, even if prominently displayed, as that would give users the choice of whether they’d like to try the new format. If users aren’t even willing to try it after being offered, that’s also valuable feedback that Google should take on board.

Microsoft says Russian companies will be forced off its cloud services within days

Despite recent reports that Microsoft was all set to ban Russian companies from its suite of cloud services from March 20, it turns out this still isn’t in effect, but should be by the end of March 2024 - this week - instead, after the company held discussions with IT platform Softline, one of its customers.

As a reminder, the ban isn’t a political move on Microsoft’s part, but several cloud storage providers’ hands being forced by economic sanctions imposed by the European Union on Russian-owned companies back in December 2023 as a result of the ongoing Russia-Ukraine conflict.

The latest update on the imminent blockade, from BleepingComputer, is that the delay so far appears to only be something that Microsoft is offering, in response to correspondence with Softline, despite the latter issuing a press release (Russian language, machine-translated by us) last week in which it claimed that it has ‘all the necessary resources’ to ensure a smooth transition to its own infrastructure from Microsoft and Amazon services. 

EU economic sanctions on Russian tech

Before the extension, in a letter that Softline has since published on its Telegram channel, Microsoft broke the news gently to Softline, but stated its ‘[commitment] to compliance with EU trade laws and regulations, as well as all other jurisdictions in which it operates’.

According to Russian news agency TASS, Microsoft stands to cut off access to over 50 of its products to Russian companies, including video conferencing software behemoth Microsoft Teams and collaboration tool suite Microsoft 365.

That’s not to mention the collateral damage caused by providers such as Google and Amazon withholding their own services without postponing the deadline. BleepingComputer also revealed that business customers of those companies based in Russia received notice of service termination last week.

It’s too early to say whether the sanctions will be effective in applying pressure on Russia to withdraw from the conflict: they could, for instance, merely drive the popularity of local cloud and IT providers among businesses, and fuel their expansion.

But regardless of the European Union’s ruling, there is one upside to all this: individuals and solo professionals based in Russia using cloud services from these and similar cloud services aren't affected.

Quordle FAQs: Everything you need to know

What is Quordle?

Where Wordle challenges you to guess a new five-letter word each day, Quordle presents you with four puzzles to solve. And rather than complete them in turn, you do so simultaneously. You get nine guesses, rather than the six for Wordle, but the rules are otherwise very similar. 

It's played online via the Quordle website and you can also get to it via the Merriam-Webster site, after the dictionary purchased Quordle last year

As with Wordle, the answers are the same for every player each day, meaning that you're competing against the rest of the world. And also as with Wordle, the puzzle resets at midnight so you have a fresh challenge each day.

The website also includes a practice mode - which I definitely recommend using before attempting the game proper! - and there are daily stats including a streak count. You also get Quordle Achievements - specific badges for winning a game in a certain number of turns, playing lots of times, or guessing particularly hard words.

Oh, and it's difficult. Really difficult.

What are the Quordle rules?

The rules of Quordle are almost identical to those of Wordle.

1. Letters that are in the answer and in the right place turn green.

2. Letters that are in the answer but in the wrong place turn yellow. 

3. Letters that are not in the answer turn gray…

4. …BUT the word you guess appears in all quadrants of the puzzle at the same time, so an A could turn green in one square, yellow in another and gray in the final two. 

5. Answers are never plural.

6. Letters can appear more than once. So if your guess includes two of one letter, they may both turn yellow, both turn green, or one could be yellow and the other green.

7. Each guess must be a valid word in Quordle's dictionary. You can't guess ABCDE, for instance.

8. You do not have to include correct letters in subsequent guesses and there is no equivalent of Wordle's Hard mode.

9. You have nine guesses to find the Quordle answers.

10. You must complete the daily Quordle before midnight in your timezone.

What is a good Quordle strategy?

Quordle needs to be approached in a different way to Wordle. With four puzzles to solve in nine guesses, you can't blindly throw letters at it and expect to win - you'll stand a far better chance if you think strategically.

That's the case in Wordle too, of course, but it's even more important in Quordle.

There are two key things to remember. 

1. Use several starting words

Firstly, you won't want just a single starting word, but almost certainly two or three starting words. 

The first of these should probably be one of the best Wordle starting words, because the same things that make them work well will apply here too. But after that, you should select another word or possibly two that use up lots more of the most common consonants and that include any remaining vowels.

For instance, I currently use STARE > DOILY > PUNCH. Between them, these three words use 15 of the 26 letters in the alphabet including all five vowels, Y, and nine of the most common consonants (S, T, R, D, L, P, N, C and H). There are plenty of other options - you might want to get an M, B, F or G in there instead of the H, maybe - but something like that should do the trick.

If all goes well, that will give you a good lead on what one or sometimes two of the answers might be. If not, well good luck!

2. Narrow things down

Secondly, if you're faced with a word where the answer might easily be one of several options - for instance -ATCH, where it could be MATCH, BATCH, LATCH, CATCH, WATCH, HATCH or PATCH - you'll definitely want to guess a word that would narrow down those options. 

In Wordle, you can instead try several of those in succession and hope one is right, assuming you have enough guesses left. It's risky, but will sometimes work. Plus, it's the only option in Hard mode. But in Quordle, this will almost certainly result in a failure - you simply don't have enough guesses.

In the scenario above, CLAMP would be a great guess, as it could point the way to four of the seven words in one go.
