Telegram Disputes Russia’s Claim Its Encryption Was Compromised

Published

on

Russia’s domestic intelligence agency claimed Saturday that Ukraine can obtain sensitive information from troops using the Telegram app on the front line, reports Bloomberg. The fact that the claims were made through Russia’s state-operated news outlet RIA Novosti signals “tightening scrutiny over a platform used by millions of Russians,” Bloomberg notes, as the Kremlin continues efforts to “push people to use a new state-backed alternative.”

Russia’s communications watchdog limited access to Telegram — a popular messaging app owned by Russian-born billionaire Pavel Durov — over a week ago for failing to comply with Russian laws requiring personal data to be stored locally. Voice and video calls were blocked via Telegram in August. The pressure is the latest move in a long-running campaign to promote what the Kremlin calls a sovereign internet that’s led to blocks on YouTube, Instagram and WhatsApp… Foreign intelligence services are able to see Russia’s military messages in Telegram too, Russia’s Minister for digital development, Maksut Shadaev, said on Wednesday, although he added that Russia will not block access to Telegram for troops for now.

Telegram responded at the time that no breaches of the app’s encryption have ever been found. “The Russian government’s allegation that our encryption has been compromised is a deliberate fabrication intended to justify outlawing Telegram and forcing citizens onto a state-controlled messaging platform engineered for mass surveillance and censorship,” it said in an emailed response.

Hackaday Links: February 22, 2026

Published

on

We’ll start things off this week with some breaking news from NASA: just days after the space agency announced the Artemis II crew was preparing to blast off towards the Moon as soon as March 6th, a new problem with the Space Launch System rocket has pushed the launch back indefinitely. According to NASA Administrator Jared Isaacman, problems encountered while loading helium into the Interim Cryogenic Propulsion Stage (ICPS) necessitate rolling the massive rocket back to the Vehicle Assembly Building (VAB) for diagnosis and repair.

The logistics of shuffling the vehicle 6.8 kilometers (4.2 miles) from the pad to the VAB is going to eat up at least a week, and sending it back the other way is naturally just as much of a production. Add in the time they’ll need to actually figure out what’s wrong with the ICPS and make the necessary repairs, and it’s easy to see why a March launch is almost certainly off the table. It’s frustrating to see the Artemis II mission get delayed this close to launch, but sending humans into space isn’t the sort of thing you can cut corners on.

Boeing’s Uber rating is in shambles.

Well, you’d think so at least. This week NASA also released a scathing report detailing the multitude of technical issues that came up during the 2024 test flight of Boeing’s CST-100 Starliner spacecraft. While astronauts Butch Wilmore and Suni Williams eventually made it back home safely aboard a SpaceX Dragon, the space agency has still categorized it as a Type A mishap — their highest incident classification and the same rating given to the losses of Apollo 1, Challenger, and Columbia.

On the subject of companies we love to hate, a recent post by Brian Merchant on his blog Blood in the Machine (awesome band name, called it) points out the precipitous rise in Flock attacks. That is, folks are taking matters into their own hands and destroying the surveillance devices all over the US. Now Hackaday certainly isn’t condoning the destruction of anyone’s property, but we definitely appreciate the rebellious cyberpunk vibe.

Before you go out hunting for Flocks, keep in mind that at least one person has caught a charge already. In fact Jefferey Sovern picked up thirteen charges, as that’s how many Flock cameras he managed to bag before the law caught up to him. According to reports, he also admitted to “keeping some of the wiring, batteries and solar panels taken from the cameras.” Sounds like Jeff would fit in just fine around these parts.

Looking for some new wheels? Got a handy source of hydrogen? If so, you might be in luck. According to CarBuzz, the resale value of Toyota’s Mirai has absolutely cratered. When they were sitting on the lot a new Mirai would have cost you a bit more than $50,000, but on the second-hand market you can get last year’s model for as little as $15,000. If you’re not too picky, you can get one even cheaper. We did a little searching of our own, and found a 2021 Mirai with less than 40K miles for just $9,000. That’s an insane price for a mid-size luxury car, but of course it doesn’t really matter how cheap the car is if you can’t find anywhere to fill the thing up.

Finally, the folks at F-Droid have sounded the alarm about some concerning changes Google has planned for Android. As we first covered back in October, anyone looking to develop applications for the world’s most popular mobile operating system will soon have to register with Google through a process which is still not entirely clear. Although the search giant has hinted that the system will feature some special consideration for students and hobbyists, F-Droid isn’t convinced. Until there is more transparency, they are urging developers and Android users to push back via keepandroidopen.org.

NASA Delays Launch of Artemis II Lunar Mission Once Again

Published

on

NASA has once again postponed the launch of Artemis II, the crewed lunar flyby mission, setting a new launch window for April. Although March 6 had been tentatively planned as the launch date, the US space agency revealed that a problem with the rocket has caused further delay.

According to NASA administrator Jared Isaacman, the failure was due to an interruption in the helium flow in the interim cryogenic propulsion stage of the Space Launch System (SLS). The helium flow is essential for purging the engines and pressurizing the fuel tanks. This system had functioned correctly in the two dress rehearsals conducted this month, but the failure occurred during a routine operation.

Due to the nature of the problem, NASA engineers will have to fix it from the Vehicle Assembly Building (VAB), so there’s no way to proceed with the March launch window. The rocket is on its way back to the hangar.

“I understand people are disappointed by this development,” the official stated on his X account. “That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor. During the 1960s, when NASA achieved what most thought was impossible, and what has never been repeated since, there were many setbacks.”

Will Artemis II be able to embark on its mission in April? NASA reported that rapid preparations have allowed it to potentially preserve the April launch window in the event of a reversal. It all depends on what the data, the repair efforts, and how the schedule comes together in the coming days.

Artemis II: The Setbacks

The mission had its first launch window between February 6 and 11. However, during the wet dress rehearsal (WDR), which is a full rehearsal with fuel, the team detected small hydrogen leaks during refueling and some minor technical glitches. After analyzing the situation, NASA concluded that the risk was considerable and could endanger the lives of the astronauts, so it decided to postpone the launch.

A second dress rehearsal, conducted on February 19, was successful. In a statement, the space agency explained that it loaded 700,000 gallons of liquid propellant with no leaks. “During the test, teams closely monitored liquid hydrogen fueling operations, which proved challenging during previous tests. Hydrogen gas concentrations remained under allowable limits, giving engineers confidence in new seals installed in an interface used to route fuel to the rocket,” NASA said.

At a subsequent press conference, mission representatives confirmed to the media that the new tentative liftoff date would be March 6. However, on February 20, the team failed to get helium to flow through the vehicle, a failure that also occurred during testing of the Artemis I mission. Isaacman noted that the cause could be due to a faulty filter, valve or connector plate.

“There are many differences between the 1960s and today, and expectations should rightfully be high after the time and expense invested in this program,” Isaacman said in his post. “I will say again, the President created Artemis as a program that will far surpass what America achieved during Apollo. We will return in the years ahead, we will build a Moon base, and undertake what should be continuous missions to and from the lunar environment.”

When it eventually launches, the Orion capsule will travel farther than any other manned spacecraft during its 10-day mission, surpassing on the sixth day the record of 400,171 kilometers set by Apollo 13. The return will conclude with Orion’s landing in the Pacific Ocean off the coast of San Diego, California.

Although there will be no lunar landing—that feat will fall to the Artemis III mission—the second launch is of crucial importance. Its success will demonstrate that NASA has the technical capabilities to return to the moon and begin a new phase of space exploration.

AMD reportedly pauses Ryzen Z1 drivers for gaming handhelds

Published

on

Owners of handheld gaming PCs powered by AMD’s Ryzen Z1 chips may have reason to feel uneasy. What started as a support message regarding the Lenovo Legion Go has quickly turned into a broader concern that driver updates for the Ryzen Z1 and Z1 Extreme platform may have slowed or even paused across multiple devices.

The situation first came to light when Lenovo Korea reportedly informed customers that the original Legion Go would not receive further BIOS or driver updates. Instead, users were advised to rely on Windows Update and generic AMD drivers, where compatible. Now, additional reports suggest the issue may extend to ASUS’s popular ROG Ally, another flagship Ryzen Z1 Extreme handheld. According to user reports, the device appears to be stuck on graphics drivers dating back to August 2025, with no newer releases despite several major game launches since then.

Is handheld driver support quietly stalling?

This detail matters because the ROG Ally and Legion Go are the two most recognizable Windows gaming handhelds powered by AMD’s custom Z1 silicon. If both devices are relying on older drivers, it suggests the slowdown could be happening at the platform level rather than being isolated to a single manufacturer.

Adding to the confusion, Lenovo forum posts also warn users not to install Legion Go S drivers on the original Legion Go. Interestingly, the Legion Go S uses the Z2 Go chip based on the older Zen 3 architecture, while the Z1 Extreme, whose updates now appear to have stalled, is built on the newer Zen 4 architecture. The generational mismatch makes cross-installation risky and further limits options for affected users.

Driver updates play a crucial role in handheld gaming performance. They often bring game-specific optimizations, power management refinements, and bug fixes tailored to each device’s thermal and battery constraints. Without consistent updates, handheld PCs risk gradually falling behind newer games and evolving Windows builds. For handheld gamers, the uncertainty is the biggest concern. While nothing has been officially confirmed by AMD yet, with both Legion Go and ROG Ally owners noticing stalled updates, the conversation around long-term handheld support is clearly gaining momentum.

Skip The Steam Machine And Build This Better Alternative That May Save You Money

Published

on





We may receive a commission on purchases made from links.

The Steam Machine promises to be an interesting gaming console, delivering the flexibility and performance of an entry-level gaming PC without the complexity of Windows. Note that isn’t the first time that Valve made a Steam Machine, as this console’s first iteration arrived in 2014. Unfortunately, the first-generation console flopped hard, and the gaming company pulled the last of the Linux consoles from its platform in 2018.

Advertisement

One of the reasons that the original Steam Machine didn’t take off was the lack of gaming developer support for the Linux-based SteamOS that it used. This has changed, however, with the arrival of the Steam Deck and the Proton compatibility layer, which allows non-Linux native titles to run on the handheld console. This meant that, slowly but surely, gamers can ditch Windows (which has its fair share of bugs and other issues) while enjoying titles primarily made for PC.

Steam Deck’s success led Valve to announce a second-generation Steam Machine in late 2025, with the console originally expected to arrive in early 2026. Unfortunately, the company announced that it will delay the launch of the gaming PC console. So, if you cannot wait for the new Steam Machine to arrive and instead want to build your own, these are the components that you should look at.

Advertisement

A comparable CPU

The Steam Machine will come with a 6-core AMD Zen 4 x86 processor that can hit up to 4.8 GHz and comes with a 30-watt TDP. This means that it won’t be based on the newer Ryzen 9000 series, which uses the newer Zen 5 architecture. So, we will look at processors that use the older Zen 4 architecture without an integrated GPU, have six cores, and has a boost clock speed of around 4.8 GHz that you can purchase from Amazon or Newegg.

That limits us to the following options: the Ryzen 5 8400F, the Ryzen 5 7500F, and the Ryzen 5 7400F. These chips all have 6 cores (12 threads), have a 4.7 GHz boost clock (except for the Ryzen 5 7500F which can hit 5.0 GHz), and 32 MB of L3 Cache (except for the Ryzen 5 8400F which only has 16 MB). All of them also have a TDP of 65 watts, which is the lowest that we could find. The Ryzen 5 8400F is currently priced at $143.92 on Amazon, making it the cheapest option. The Ryzen 5 7400F, which was initially launched as a China exclusive, is now available on Newegg for $147.59, while the slightly faster Ryzen 5 7500F costs $163.99.

Given these options, we suggest picking up the Ryzen 5 7400F, which is priced at the middle of the pack. It only has a slightly lower boost clock than the 7500F while costing about $15 less. And even though the 8400F is more affordable, you’re going to appreciate the 32 MB L3 Cache of the 7400F, which helps improve minimum frame rates to deliver smoother gameplay.

Which AMD GPU should you get?

Valve said that its latest gaming PC console will come with a semi-custom GPU, meaning we won’t be able to find a 1:1 analog for it. Nevertheless, the company specced the Steam Machine with an AMD RDNA 3 graphics card with 28 CUs (or Compute Units), 8GB GDDR6 VRAM, a maximum sustained clock speed of 2.45 GHz, and a 110-watt TDP. Since Valve uses an RDNA 3 GPU, that means we’re limiting our options to AMD Radeon RX 7000-series GPUs.

If we look at all the discrete GPUs under the 7000 desktop series family, there are two models that are close to Valve’s specifications: the AMD Radeon RX 7600 and the RX 7600 XT, both of which have 32 CUs. The latter has a 2.47 GHz Game Frequency, nearly matching what the Steam Machine has, but has a maximum memory size of 16 GB. On the other hand, the non-XT version matches the semi-custom GPU’s 8 GBs of VRAM but has a much lower 2.25 GHz Game Frequency. Both GPUs also require a higher TDP — 190W for the RX 7600 XT and 165W for the RX 7600.

However, the 7600 XT is quite expensive, with the cheapest model we can find costing well over $500.  Because of this, we’re picking the $274.99 Asus Dual Radeon RX 7600 EVO OC GPU on Amazon, which has a similar 8GB of VRAM and a lower TDP. While it’s possible that Valve will choose a laptop GPU, we’re not going to go in that direction because most consumers cannot purchase that as a standalone unit.

Finding compatible memory, storage, and motherboard

Valve said that the Steam Machine will come with 16 GBs of SO-DIMM DDR5 laptop memory, although it’s unclear if it will have one or two RAM sticks. But because we’re using desktop components, we will just stick with two 8GB DDR5 RAM sticks. Since memory modules are prohibitively expensive at the moment, we’ll get the most affordable unit we can find — the Patriot Viper Venom 16 GB (2 x 8 GB) DDR-6000, which costs $199.99 on Newegg.

For storage, the Steam Machine is available with either a 512 GB or 2 TB SSD — since we’re trying to keep our costs down, we’ll stick with a 512GB SSD. The console also uses the smaller 2230 form factor for its storage, but we’re going with the larger 2280 instead, because it’s cheaper. So, for our storage, we picked the Patriot P400 Lite M.2 PCIe Gen 4 x4 500 GB SSD, which will set us back $80.99 on Newegg. If you can afford to spend a little bit more, it’s wiser to get at least 1TB so that you don’t run out of space for installing all your favorite titles.

Advertisement

Finally, we need to get a motherboard that will accommodate all our chosen components so far. Unfortunately, the smaller Mini ITX motherboards are out of our budget, so we’ll stick with the most affordable compatible Micro ATX motherboard instead. But even though we’re on a budget, we’re avoiding the most basic chipsets like the A620 because we’re still building this for gaming. For that reason, we’re picking the ASRock B650M-HDV/M.2, which costs $99.99 on Amazon.

Advertisement

Which PSU, case, and cooler should we get?

AMD recommends a minimum 550-watt power supply for the AMD Radeon RX 7600, so we’ll stick with that for safety. Even though we want a compact build, SFX power supplies built for small form factor (SFF) PCs are quite expensive and will cause us to go overbudget. So, we’ll instead go for the MSI MAG A550BN, which is a cheap but reliable PSU, costing only $54.99.

Now that we have power, we need to put everything inside a case. While we’d love to stick with an SFF case, these are just too expensive. So, we’re going one size up with the Cooler Master MasterBox Q300L, which just costs $39.99 on Amazon and Newegg. It can accommodate a PSU up to 160 mm, ensuring that the MSI MAG A550BN will fit inside it. It also gives us the option to install a 240mm radiator for an AIO liquid cooler, but since we don’t want to spend too much on any component, we’re sticking with air cooling.

Speaking of cooling, we still need to get a CPU cooler because the AMD Ryzen 5 7400F is a tray processor, meaning it doesn’t come with a stock cooler. We also deliberately kept it last so that we know how much clearance we need with the PC case. Cooler Master says that the MasterBox Q300L has 159 mm of space for an air cooler, meaning one of the best air coolers on the market, the Thermalright Peerless Assassin 120 SE, with its 155 mm height, would fit in the system. More importantly, it’s quite affordable at just $38.90.

Advertisement

How much will the full build cost?

Our build comes out at a total of $937.43. This might surprise you, especially as we tried to keep our costs down, but that is difficult with the current cost of RAM and storage. In fact, PCPartPicker shows that our RAM module’s price increased by 300% since 2025, while our SSD’s cost doubled in the same period. If we bought these components at their original prices, our cost would just be around $750. Nevertheless, you can still get some savings if you catch a sale on all the other parts. Alternatively, you can buy some of these PC parts in the used market to save money, as long as you know what to look for when doing so.

Valve said that it will not subsidize the cost of the console (unlike PlayStation and Xbox), but it claims that it’s aiming for “great value” on “the entry-level side of things.” This will be difficult, though, with RAM and SSD prices out of control. Leaks from third-party retailers suggest prices from $949 to $1,070, although some analysts have suggested a lower price. The company still hasn’t confirmed what the final cost of the console will be, but we expect it to be higher than early estimates. 

Although the savings you get when you go through the DIY route is quite small, it still offers a couple of advantages. For one, you can set your own specs — if you have extra cash, you can opt for more powerful components that will allow you to enjoy faster frame rates and play more demanding games on your living room TV. Another bonus of a custom build is that you can update it later, allowing you to enjoy your DIY Steam Machine for longer.

Metilis Gravity Furnace Might be the Coolest Robot Watch Winder Ever

Published

on

Metilis Gravity Furnace Robot Watch Winder
A gravity-wielding winder appears, which resembles a sci-fi gadget rather than something you’d want on your desk. Metilis refers to it as the Gravity Furnace, which will come as no surprise. This single-watch winder spins automatic watches with the precision of a Swiss watchmaker, but instead of a boring wooden box, it resembles a chunky robot from an old-school anime.



Collectors of automatic watches will understand that you have to keep these bad boys moving when they’re not on your wrist or it just stops working. Standard winders do the work quietly inside an oak case, rotating the watch in smooth cycles, but the Gravity Furnace is unique. It’s designed around a robot arm that wraps around and rotates the watch, all encased in a full-metal shell with sharp pieces and modular panels that can be swapped out for a new look. It has an industrial air, as in, “I’ve got a garage full of tools.” There are adjustable side plates, odd antenna-like pieces, and even swappable metal or rubber feet to give it a unique look.

NASA’s Perseverance Rover Can Now Pinpoint its Location on Mars

Published

on

NASA Perseverance Mars Global Localization GPS
NASA’s Perseverance rover has just reached a small but significant milestone on Mars. After five years of carefully traveling about the bottom of Jezero Crater, the rover now knows exactly where it is without having to rely on a crew on Earth. A new system called Mars Global Localization has made the task possible in less than two minutes, with accuracy to within ten inches.



Engineers at NASA’s Jet Propulsion Lab came up with the idea of allowing the rover to match what it sees on the ground to the super precise maps acquired from space. Perseverance begins by capturing a full 360-degree panorama with its cameras, similar to the vision you get when spinning around in a circle. It then stitches that together to provide a circular perspective from above, similar to a bird’s-eye view. The software then compares that to some ultra high-resolution topography maps taken by the Mars Reconnaissance Orbiter.

  • AR brings the mission to life – The accompanying augmented reality app experience lets kids dive into the details of the rover and its mission

Matching up the features between the two is quick since the program just looks for similar rocks, ridges, and slopes in both the rover’s perspective on the ground and from space. And once it finds a match, the rover is quite accurate. The entire operation is powered by an outdated processor from the Ingenuity helicopter, which is far faster than the technology in the rover. That’s why it can all be done in two minutes.

NASA Perseverance Mars Global Localization GPS
Perseverance had previously become trapped as it drove larger distances. The visual odometry was attempting to follow how the rocks around it moved in the camera frames, but the wheel simply slipping on the soft soil was causing the position to shift over time. After a few hundred feet, the position could shift by more than a hundred feet. So the team would send it more photographs, and the specialists on Earth would manually align them with the images from space, which could take a full day or longer.

Mars Global Localization changes all of that because the rover can now determine its position immediately after a drive, make any necessary corrections, and simply keep going. With it linked with the existing AutoNav system, which can already handle obstructions, the rover can just keep going. The more ground it traverses per Martian day, the faster it will pass through Jezero Crater and beyond.

The technology underwent extensive testing prior to its debut. The engineers tested it on data from 264 previous rover pauses and found that it correctly identified every single one by comparing old photographs to space maps. Then it saw its first real use on February 2, 2026, and it worked again a few weeks later. One of the first times it was utilized was in a somewhat dull section of the crater rim known as Mala Mala, where there aren’t many fascinating landmarks to look at, but the system still managed to pinpoint the location within the target margin of error.

NASA’s crewed Artemis II launch gets pushed back again, this time due to a helium issue

Published

on

It looks like a March launch is no longer in the cards for Artemis II, NASA’s first crewed trip to the moon’s vicinity since the final Apollo mission over 50 years ago. While preparations were underway at the Kennedy Space Center for a launch as soon as March 6, the space agency says it ran into an issue with the flow of helium to its SLS rocket’s upper stage this weekend and it now has to roll the rocket from the launch pad back to the Vehicle Assembly Building (VAB) to figure out what’s wrong and fix it. A media briefing is planned for sometime this week to discuss the problem and what’s next.

But in a post on X, NASA Administrator Jared Isaacman confirmed the rollback will “take the March launch window out of consideration.” NASA noted on its blog that the current effort “potentially preserves the April launch window, pending the outcome of data findings, repair efforts, and how the schedule comes to fruition in the coming days and weeks.” It’s a four-mile trip back to the VAB that will take hours to carefully transport the massive rocket and the Orion spacecraft. NASA says it’s eyeing February 24 for this trek.

The issue occurred overnight in the early hours of February 21, when NASA says it observed “interrupted flow of helium to the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage.” The space agency explained:

The upper stage uses helium to maintain the proper environmental conditions for the stage’s engine and to pressurize liquid hydrogen and liquid oxygen propellant tanks. The systems worked during NASA’s Artemis II wet dress rehearsals, but teams were not able to properly flow helium during normal operations and reconfigurations following the wet dress rehearsal that concluded Feb. 19. Operators are using a backup method to maintain the environmental conditions for the upper stage engines and the rocket, which remains in a safe configuration.

The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch and Canadian Space Agency astronaut Jeremy Hansen, Mission Specialist — had just entered quarantine a day before the issue arose. NASA says the astronauts have since come out of quarantine.

At the start of this year, NASA announced an accelerated timeline for Artemis II, which was previously set for April 2026 after experiencing delays in 2024. For this 10-day mission, which will be the first crewed flight of the SLS rocket, the Artemis II astronauts will take a trip around the moon in the Orion spacecraft. While it initially targeted early February, the launch was pushed to March due to issues that popped up during the wet dress rehearsal. Now, we’re back to the beginning with a possible April launch, but that’ll depend on the fix being a quick one.

  • AI-generated passwords follow patterns hackers can study
  • Surface complexity hides statistical predictability beneath
  • Entropy gaps in AI passwords expose structural weaknesses in AI logins

Large language models (LLMs) can produce passwords look complex, yet recent testing suggests those strings are far from random.

A study by Irregular examined password outputs from AI systems such as Claude, ChatGPT, and Gemini, asking each to generate 16-character passwords with symbols, numbers, and mixed-case letters.
