7-Zip fixes RCE flaw exploitable with malicious archives

Published

on

7-Zip

7-Zip version 26.02 was released to fix a remote code execution vulnerability that could allow attackers to execute malicious code by convincing users to open specially crafted compressed files.

The vulnerability, disclosed by Lunbun researcher Landon Peng, exists in 7-Zip’s processing of XZ-compressed data.

According to an advisory from the Zero Day Initiative, specially crafted XZ data can trigger a heap-based buffer overflow, potentially allowing attackers to execute arbitrary code as the user.

While the developer has not published technical details about the flaw, the changes in the 26.02 source code suggest it is related to how 7-Zip tracks available space while decompressing XZ data.

The patch adds checks to ensure the decoder cannot write beyond the remaining available space in an output buffer, helping prevent a heap-based buffer overflow.

The advisory states that exploitation requires user interaction, such as visiting a malicious page or opening a malicious archive file.

No automatic update feature

As 7-Zip does not include an automatic update feature, users will not receive the security fix automatically. Instead, they must install it manually by downloading the latest version from the program’s official site, 7-zip.org.

Because 7-Zip is one of the most widely used archive utilities on Windows, security flaws impacting its archive features are an attractive target to threat actors.

A phishing campaign or social engineering attack could be used to distribute a malicious archive that exploits the flaw to install malware on vulnerable systems.

This is not far-fetched, as archive vulnerabilities, including those in 7-Zip, have been exploited in past attacks.

In early 2025, a 7-Zip vulnerability that allowed malware to bypass Windows’ Mark of the Web (MotW) security feature was exploited by Russian hackers as a zero-day.

Later that same year, a Russian hacking group exploited a WinRAR vulnerability tracked as CVE-2025-8088 via phishing attacks to install the RomCom malware.

There are currently no reports that attackers are actively exploiting this newly disclosed 7-Zip vulnerability.

However, users are advised to update to version 26.02 as soon as possible to reduce the risk of future attacks.

People’s Picks TV Winners: Upgrading Your TV Soon? CNET Readers Have a Favorite Brand

Published

on

Any device you buy is an investment. You want the reassurance that it’s going to meet your short- and long-term needs for a while before you have to buy a new one. That’s true for smartphones, laptops and especially TVs

Upgrading your TV means deciding on which brand is worth your hard-earned bucks. Picture quality, sound, smart features and the display panel are just some of the specifications you may consider. And CNET readers have opinions on all of that and more. 

CNET’s People’s Picks gives readers a chance to share their opinions on their TV brand. Many of you love LG, but some readers have opinions on other brands that you may not have considered before now. Here’s which brands won readers over and what our experts think.

LG/J. Hazelwood/CNET

LG is well-known among TV brands for its OLED screens, and it’s a favorite among CNET editors and readers. LG earns high marks in many of CNET’s People’s Picks categories and wins three awards from readers: picture quality, fast-moving content and OLED/QD-OLED.

CNET editors give LG several nods for recent OLED TVs, lauding the contrast in the new C6H, the color accuracy of the G5 — recipient of a CNET Lab Award — and the contrast and brightness of G6 for movie buffs. The LG OLED G4 is one of the best gaming TVs for its top-notch gaming features, especially as a more cost-effective option compared to the LG G6.

Picture quality

Runner-up: Sony

CNET readers crown LG as a winner for picture quality. More than 3 out of 5 (61.7%) of CNET readers who own an LG TV reported an “Excellent” experience with their LG TVs in bright rooms and during the day. Readers say there’s no glare and it’s beautifully bright, and 65.1% of readers with LG TVs report perfect dark scenes with inky blacks and zero light bleed — performance that’s common on OLED models and can really improve the look of movies and TV shows. That brings LG’s picture quality to 63.4%. 

Sony is a runner-up for picture quality, based on nearly half (49.8%) of readers with a Sony TV saying the brand has inky blacks with no bleed and great daylight performance.  

Fast-moving content

Runner-up: Sony

LG wins for flawless, fast-moving content. Of readers, 71% say LG TVs are perfectly smooth, are without blur and are without weird, artificial artifacts with fast-moving content, whereas 28% say LG’s fast-moving content quality is natural but occasionally slightly blurry. When it comes to gaming, CNET readers (59.8%) who have an LG TV say fast-moving content is flawless and incredibly responsive and that the TV has great gaming menus. 

Sony is the next top pick, with 60% of readers saying its fast-moving content is flawless on Sony TV screens.

OLED/QD-OLED

Runner-up: Samsung

Lastly, LG sweeps the OLED/QD-OLED category with 82.4% of readers with an LG TV preferring the brand for its OLED displays. If you’re considering an LG OLED TV, the latest LG OLED G6 has excellent contrast, an improved antireflective coating and good brightness for gaming. One of CNET’s lab-tested favorites is the previous LG OLED G5. CNET editors say it has the best color accuracy. The C4 is still a favorite, but if you want the latest and greatest, LG’s C6 and C6H are standout OLED picks. The C6 is the ultra version of the C6 TV, and it comes in larger sizes with higher brightness and better colors.

Samsung trails behind LG with 45% of readers who own a Samsung TV have an OLED or QD-OLED model. That’s not surprising because Samsung has only been selling OLED TVs since 2022 after a single model in 2013, whereas LG’s OLED models have been on sale for more than a decade. Both the S90F and S95F are Samsung OLED TVs that get praise from CNET for image quality and glare reduction. 

Roku

Roku/J. Hazelwood/CNET

Budget TV

Runner-up: Vizio 

Roku wins three categories in CNET’s People’s Picks — budget, smart TV ecosystem and standard LED/LCD. Roku has several affordable TVs. Most CNET readers (72%) have purchased a Roku TV that’s under $500. And nearly half of readers with Roku TVs have purchased their TV within the past year. 

Roku has a few popular TV picks under $500, including the TCL 4-Series, the Pioneer 50-inch 4K smart Roku TV and the Roku – 40″ Class Select Series Full HD (1080p) LED Smart RokuTV. Roku’s cost-effective options don’t skimp on quality. For instance, the Pioneer 4K Roku TV is an LED TV with 4K resolution and a smart TV interface, and it supports High Dynamic Range to improve your picture quality.

Vizio is next up to Roku, with 45% of readers having Vizio TVs costing less than $500. If you’re in the market for a mini-LED TV, Vizio has its Mini LED Quantum Series 4K TV for under $500 in two sizes (65 and 75 inches). Interestingly, 40.8% of CNET readers with Vizio TVs have had them the longest (over five years) — speaking to its quality and longevity for the price.

Smart TV ecosystem 

Runner-up: TCL

Trust me, a smart TV’s interface can make or break your day-to-day experience. Roku understands that and wins over 59.1% of CNET readers. 

Most readers with a Roku TV say its interface is fast, clean and very easy to navigate. No readers reported the interface being cluttered, slow or frustrating to use — the only TV brand to do so. Roku recently released a new interface that includes a “For You” section, which combines AI suggestions, saved entertainment and what you’re already watching. And the new interface has a “Quick Access” section to get to your most used apps faster, but we have a guide if you’re not a fan and want to turn it off.

TCL is a runner-up for the Smart TV ecosystem category. Over half (56.5%) of readers who own a TCL TV say the interface is fast, clean and easy to navigate, while 22.5% say the interface is good but has too many ads or sponsored recommendations. 

Standard LED/LCD

Runner-up: Vizio 

Standard LED and LCD TVs use LED backlights and are usually the most cost-effective compared to other TVs. Roku wins 34.8% of its owners over for this category. There are a few budget-friendly Roku LED TVs worth considering, including the Onn 43-inch Class 4K Roku smart TV and the Hisense 50-inch Class 4K LED Roku smart TV. The Roku Select Series LED TV is a CNET favorite for its usability features, like Roku’s interface and remote finder. 

Readers say Vizio is the next top pick for LED/LCD TVs, with 32.7% owning an LED or LCD Vizio TV.

Hisense

people's picks badge with hisense logo

Hisense/J. Hazelwood/CNET

Sound quality 

Runner-up: Sony

Hisense wins CNET’s People’s Picks for its sound quality. Nearly half of readers (45.7%) with Hisense TVs rate the internal audio as “great.” And that’s nearly double CNET readers’ satisfaction with popular brands like Sony (25.2%), Samsung (23.8%) and Vizio (22.2%). One of the perks of Hisense’s latest U7 and UR8 models is Dolby Atmos, which uses surround sound to deliver 3D audio. The U7 models also have a built-in 2.1.2-channel speaker system for more immersive sound. CNET’s favorite budget TV, the Hisense QD7 TV, also supports Dolby Atmos. 

Sony is next up for the sound quality category, with 25.2% of owners saying Sony TVs have great sound quality with clear dialogue and decent bass. Some (41.7%) say it’s adequate for casual watching. 

TCL

Mini-LED/QLED 

Runner-up: Hisense 

Mini LED TVs use tiny LEDs to give you better brightness, blacks and contrast compared to most standard LED TVs. When it comes to mini-LED and QLED TV panels, TCL wins, with 57.5% of readers owning mini-LED/QLED TCL TVs and naming it their primary TV brand. TCL has been producing mini-LED TVs longer than most TV makers, and many of them have earned CNET’s praise.

According to CNET editors, the TCL QM8K is nearly comparable to an OLED TV in terms of picture quality for less money. TCL’s QM8L is another mini-LED QLED TV that CNET loves for its brightness, color and contrast, too. 

Over half (52.1%) of readers with a Hisense TV have a mini-LED/QLED TV, with its model ranking second to TCL. Hisense has a few mini-LED models, including the U6, U7 and the new RGB mini-LED UR8, which we got a glimpse of at CES 2026. It’s around $1,300 and comes with better-than-before color reproduction. 

Don’t buy a new TV without reading this first

Many TVs have similar features that may make it seem like the best deal is the biggest screen for your buck. Of everything to consider, CNET’s TV expert Ty Pendlebury advises looking at price, size and picture quality to help narrow down your options.

“It’s always what fits their budget, so not necessarily a ‘budget’ model. If an OLED is within your budget, get it, that’s the quickest shortcut,” said Pendlebury. 

And don’t worry about perfecting your TV’s sound quality during your upgrade. Pendlebury says that most TVs sound tinny, so you should consider a soundbar as a separate purchase for better audio.

CNET’s editor-in-chief, David Katzmaier, has 26 years of experience reviewing TVs and has some practical advice to help you feel more satisfied with your purchase years later. For instance, bigger doesn’t always mean better. 

“A bigger TV is great, but it can expose lower-quality sources,” said Katzmaier. The reason is that a bigger screen can show imperfections more than a smaller one. If you still want a bigger screen, consider subscribing to 4K plans to streaming services like Netflix and YouTube TV for better picture quality. You can also try adjusting your picture settings, such as putting the TV in Filmmaker Mode, but Katzmaier says that’s not a cure-all.

Instead of screen size, focus on getting a picture quality you’re satisfied with. “The biggest improvement would be getting a new display technology, especially QD-OLED/OLED,” said Katzmaier. “TVs with those kinds of screens deliver clear improvements in contrast and viewing angle that the others can’t match.”

CNET editors and readers highly recommend LG. But other brands were close runners-up. If you’re looking for deep black levels and strong color reproduction, readers recommend Sony as a second contender. Or if you’re struggling to watch TV in a room with a big window, consider TCL or Samsung — all CNET favorites.

“I’ve always liked Roku and Google TV better than proprietary systems from Samsung and LG, and I’m happy to see that CNET readers took our advice and bought LG and Samsung OLED TVs — because they’re the picture-quality champs,” said Katzmaier.

CNET has plenty of reviews of some of the latest TVs, like the TCL QM8L, if you’re looking for a brighter TV, or the Samsung S90F, if you’re looking for the best value for overall picture quality. Regardless, there are also guides to help narrow down your TV choice, like choosing between LCD and OLED TVs, what to know about micro-LED and a list of everything to look for when buying a new TV

FBI arrests 21-year-old accused of infecting 8,000 PCs with malware through fake Steam games

Published

on

The big picture: A 21-year-old Florida resident was arrested last week for allegedly stealing more than $220,000 in cryptocurrency through malware hidden in video games. Although the indictment does not identify the storefront that hosted the infected games, it mentions several titles that were listed on Steam until recently.

The suspect, identified by the FBI as Zyaire Dontaevious Zamarion Wilkins, is accused of running a sophisticated cybercrime operation with unnamed co-conspirators for nearly two years. The group allegedly infected around 8,000 PCs by embedding malware in at least eight video games. Investigators believe they stole at least $220,000 from roughly 80 cryptocurrency wallets between May 2024 and February 2026.

The FBI charged Wilkins and his associates with several cybercrime offenses, including conspiracy to distribute malware. According to investigators, the suspects promoted the infected games on popular social media and messaging platforms such as Discord, Telegram, X, and LinkedIn. They also allegedly targeted users with large cryptocurrency holdings by identifying them with bots and contacting them directly.

The malware was designed to extract passwords and other sensitive data from victims’ computers, then use that information to steal cryptocurrency from their online wallets. The FBI ultimately tracked the suspects by linking the stolen bitcoin to more than 150 Bitrefill gift cards, which were reportedly used primarily to pay for Uber Eats orders.

According to the FBI’s complaint, the list of infected games includes BlockBlasters, Dashverse, Lunara, and PirateFi. All of them remained available on Steam until earlier this year, when the FBI announced it was investigating malware on the platform and urged anyone who had downloaded the infected games to come forward and assist with the investigation.

According to forensic cryptocurrency researcher ZachXBT and the online malware repository vx-underground, BlockBlasters alone accounted for roughly $150,000 of the stolen cryptocurrency from between 261 and 478 victims. That included $32,000 stolen from Twitch streamer RastalandTV in September 2025. The streamer, who was undergoing cancer treatment, had received the money as donations from viewers to help cover medical expenses.

The FBI believes Wilkins financed the entire operation and marketed the malware to underground cybercriminals. Investigators also identified the developer suspected of writing the malware and searched the individual’s property for additional evidence. According to Miami news station WPLG Local 10, Signal chats recovered from the developer’s devices linked Wilkins to the operation.

The messages reportedly revealed that Wilkins, who allegedly operated under the dark web alias Sibel.eth, purchased a $10,000 remote access trojan and discussed the best ways to trick victims into approving fraudulent cryptocurrency transactions. The suspected malware developer was not identified in the report and has yet to be formally charged.

These Hip-Hop Artists Were Already Teaching

Published

on

For decades, hip-hop artists have been invited into schools as guest speakers, workshop leaders and visiting performers. They’ve mentored young people after school; started nonprofits; taught music production, poetry, history and entrepreneurship; and helped generations of students find their voices.

Yet many of these artists lack the one credential schools still value most: a bachelor’s degree.

But what if these artists have been teaching all along?

A new partnership between College Unbound and the Hip-Hop Education Center aims to answer that question, not by teaching artists how to become educators but by recognizing the expertise they’ve developed through decades of community leadership, cultural work and mentorship.

Advertisement

The program — a Bachelor of Arts in organizational leadership and change designed specifically for hip-hop educators and cultural leaders — isn’t a separate degree or a simplified version of one. Students complete the same degree requirements as every other College Unbound student. “It’s the same degree,” says College Unbound President Adam Bush. “It’s simply lived differently.”

The program is about more than hip-hop. It asks a question that reaches far beyond music: Who gets to decide what expertise looks like?

A Degree Years in the Making

Although the bachelor’s degree officially launched this year, its roots stretch back decades.

Hip-hop emerged outside traditional institutions, often in response to systems that excluded Black and Brown communities. As hip-hop education gained legitimacy, educators wrestled with a difficult question: How can we preserve the authenticity of the hip-hop culture while creating pathways that allow practitioners to teach at schools and colleges?

Advertisement

Long before there was a curriculum at College Unbound, there were conversations between Bush, educator and author Sam Seidel, and Martha Diaz, founder of the Hip-Hop Education Center, who has spent nearly three decades helping to build the field of hip-hop education. These conversations focused on this central question.

For Seidel, who has spent much of his career documenting and advancing hip-hop education, the answer required finding the right institution.

“What was always important,” he says, “was making sure the people who created the culture and have been carrying it forward had a central seat at the table teaching the next generation.”

College Unbound proved to be an unusual fit. Rather than asking students to leave their experience at the classroom door, the college builds on it. Students develop projects rooted in the work they’re already doing, making professional experience, leadership and community knowledge part of the curriculum.

“This program opens opportunities for seasoned practitioners,” adds Diaz. “These are people who’ve spent decades mentoring young people, creating art and leading communities but haven’t always had access to the credentials that allow them to teach full-time.”

From the Stage to the Classroom

For Sebastien Elkouby, a hip-hop artist and educator, the degree feels less like a beginning than the fulfillment of a long-awaited opportunity.

Born in France, Elkouby spent years working in music before becoming a U.S. citizen, raising a family and earning a career and technical education credential. Today, he teaches Global Awareness Through Hip Hop Culture and Beatmaking classes at a public charter school in Los Angeles.

“When I found out about the College Unbound program, I thought, ‘Finally,’” he says. “I couldn’t have designed a better opportunity than going to college under the guise of hip-hop culture.”

His years as an emcee prepared him for the classroom in ways a traditional teacher preparation program might not have. Standing in front of students, he continues, isn’t much different from standing in front of an audience. “You have to capture their attention. You have to tell a story. Teaching is a performance.”

He sees similar parallels in curriculum design. The care he once devoted to writing lyrics with a beginning, middle and end now shapes the lessons he designs. His classes trace the historical roots of hip-hop, connecting music to social movements, politics and culture.

Asante Burks reached a similar conclusion while on a different path. Known professionally as Asante Amin, the rapper and member of Soul Science Lab believes that performing and teaching are two sides of the same coin. “On stage, I want to entertain, educate and inspire. In the classroom, I want to do exactly the same thing,” he says.

His teaching centers on the cypher, the circle where rappers, emcees and beatboxers share ideas, stories and experiences while learning from one another. In that setting, everyone becomes both teacher and learner. “It isn’t just me delivering knowledge. The collective mind is where real learning happens,” he adds.

Advertisement

That philosophy reflects one of hip-hop pedagogy’s central ideas: learning is participatory, communal and deeply connected to identity. It also challenges a persistent misconception. “People think hip-hop education is just playing rap music in class,” says Diaz. “It’s a culture, mentorship, history and community. It’s understanding students as whole people.”

Recognizing the Experts Already Among Us

A member of College Unbound’s first graduating class, Anjel Newmann now serves on the college’s faculty, leads the arts organization AS220 and serves on the school board in Providence, Rhode Island. She sees the bachelor’s degree as more than an academic credential.

“It’s helping people who have been teaching in the community move from guest speaker to lead teacher,” she says. “They know how to connect with young people who may have already tuned school out. They understand identity and community.”

College Unbound’s project-based model mirrors the way artists naturally work. “As artists, everything we do is project centered,” says Newmann. “You’re constantly researching, creating, revising and sharing your work. College Unbound allows every subject to connect to that bigger vision.”

Advertisement

For Newmann, the lesson extends beyond hip-hop. “There are experts in our communities who were blocked from credentials because of systemic barriers,” she says. “College Unbound didn’t ask them to become experts. It recognized that they already were.”

Rethinking Expertise

As colleges across the country search for new ways to serve adult learners and employers increasingly question what degrees actually measure, College Unbound offers one possible answer: Instead of asking students to prove they deserve admission, the institution begins by asking what they’ve already built.

Organizing communities, mentoring young people, leading nonprofits, creating art and solving real-world problems are acknowledged as evidence of learning. “We’re recognizing lived experience as the value that it is,” says Diaz.

Seidel hopes the program’s success ultimately will be measured by what graduates build together long after they leave. He imagines meeting them at a future gathering of hip-hop educators — that people who’ve built sustainable careers are supporting their families through education and the arts and remain connected years later. “I want to hear them telling stories about the work they’re doing together,” he adds.

Advertisement

The success of programs like this won’t be measured only by the diplomas students earn. It will be measured by whether colleges begin to recognize that expertise isn’t created the day someone receives a credential.

Burks believes that shift is inevitable.

“I think this educational process is the way of the future,” he says. “In order for education to remain meaningful and relevant, it’s going to have to implement experimental accreditation processes. It should be like music.”

Apple probably won’t add Jony Ive to OpenAI IP theft suit

Published

on

Four years ago, Jony Ive left Apple, and joined OpenAI, yet he isn’t named in the intellectual property theft suit. The reasons for that are myriad, ranging from the personal to practical.

On July 10, Apple launched what looks to become a major lawsuit against OpenAI, accusing ex-Apple employees of stealing intellectual property. However, despite former Apple design chief’s links to OpenAI, he isn’t in the crosshairs of Apple’s lawyers.

In Sunday’s “Power On” newsletter for Bloomberg, Mark Gurman writes about the lawsuit and the oddity. He believes there are two big reasons for Apple not to implicate Ive in the lawsuit at all.

The first is relatively simple: He had little to do with it.

Advertisement

Though Ive is chiefly the face of OpenAI’s new hardware work, he is seemingly focusing on that product. While Tang Tan, one of the named targets of the lawsuit, does have more control over the hardware side of OpenAI as its chief hardware officer, Ive just does not.

Ive isn’t dealing with recruiting or operations at OpenAI. Since he doesn’t have much to do with that stuff, he wouldn’t have taken part in the activities in the lawsuit.

The lawsuit largely discusses the alleged actions of Tan, including problematic emails and encouraging potential hires from Apple to bring in prototypes and designs. Tan would’ve been in a position to carry out these actions, leaving Ive’s hands clean.

Relationships and axe-grinding

The other reason for not going after Ive is all about image. Gurman believes that Ive’s closeness to Laurene Powell Jobs, entrepreneur and widow of Steve Jobs, is insulating Apple’s ex-designer.

Advertisement

Powell Jobs is a supporter of Tim Cook and John Ternus, and she still has a close relationship to the company. The impact of Steve Jobs returning and saving the company means her approval is important to Apple as a whole.

Dragging Ive into the suit would make maintaining the relationship with Powell Jobs difficult.

On top of that, the optics of attacking Ive after his major role in the company’s history and his own close relationship to Steve Jobs would hurt the company.

If he had been named, Gurman proposes that Ive would’ve received sympathy while Apple would be criticized. That criticism would also be seen as Apple having an axe to grind following Ive’s decision to leave the company.

Advertisement

Ive left in 2019, but he was a consultant until 2022 under his design company, Love From. That period saw a number of Apple designers leave the company to rejoin their leader, Ive, at his new firm.

To Apple, Ive’s leaving and the subsequent departures may have been seen by Apple as Ive dismantling the design team while still under its payroll.

Whatever the reason for Apple avoiding Ive, it has led to him being almost completely absent in the lawsuit.

In the entire 40-page document, it refers to a group of “former Apple leaders,” which you’d expect includes Ive.

Advertisement

Apple can still do a lot of damage to OpenAI’s image and hardware work with its current lawsuit, going after Tang Tan. But by avoiding the temptation of tacking on Ive, Apple does so without causing itself that much reputational harm.

First Look at Phantom Twist, the Drone That Spins Itself Into Near Invisibility

Published

on

Phantom Twist Spinning Drone Invisible
Engineers at Northwestern University have built a small flying machine that fades from view by rotating faster than eyes can follow. Phantom Twist earns its name through a constant twist that turns solid parts into a soft smear against the sky or ground below.



Standard drones attract attention since they essentially sit there with all of their weight focused in the center. Its four whirling blades lift it off the ground, but a giant still frame in the middle stands out like a sore thumb. People and animals can immediately recognize the motionless shape. A new version of this removes the “still” reference by relocating the entire assembly. In this unique design, a single motor drives only one propeller in one direction, but the rest of the system, including the batteries and control boards, spins in the opposite way and travels simultaneously. That way, you have a nice, smooth balance, and the entire piece does not hang in one spot. The only thing holding everything together are some support cables and a counterweight to keep it spinning smoothly.

When this drone is flying at top speeds of up to 25 revolutions per second, the human eye can only capture a fraction of a second. It only opens for a flash, just like a camera sensor. When you move so quickly, the image blurs and loses its clear edges. What’s left on the drone is a faint, hazy muddle that you scarcely see unless you look for it specifically. Using a human vision model, researchers evaluated the craft against a variety of backdrops, and it scored around 10 times lower on visibility than a normal quadcopter of similar size. Not because of any fancy colors or coatings, but simply because it moves so quickly that your eye doesn’t have time to lock onto it.

Phantom Twist Spinning Drone Invisible
Before settling on the final design, a team led by Professor Michael Rubenstein used computers to experiment with almost 20,000 potential designs. Each one had its flight capabilities and stealth verified in simulation before the software eliminated the weaker designs and allowed the stronger ones to proceed to the production stage. He explained that the fundamental difference with this project was that instead of attempting to hide the drone to blend in with its surroundings, they were looking at how to construct the machine in such a manner that it tested the limits of human motion perception. Emma Alexander noted that human vision forms an image over time, and moving quickly enough prevents that picture from ever solidifying clearly. Essentially, the eye receives an averaged out image of the drone blended with its surroundings, which fuses into a beautiful soft haze.

Phantom Twist Spinning Drone Invisible
Wildlife researchers will be the first to take advantage of this. You can use an invisible drone to film nesting birds or monitor animals in wetlands without disturbing or influencing their activity. You can have a guy standing on the ground evaluating bridges, towers, or pipelines while the drone hovers overhead, and he has no idea. However, there are certain limitations to this technology, such as the noise produced by spinning propellers and the tiny rods that nonetheless capture the eye in the correct light. For the time being, these factors preclude complete concealment. Future generations, however, attempt to close the gap by improving the plastics and motors. Each step should get us closer to a veil that is nearly undetectable.

A Robot Lost Its Head in the Ring During the URKL MMA Fight, It Kept Swinging Anyway

Published

on

URKL MMA Robot Fight
Shenzhen hosted the opening night of something that had never happened before. The Ultimate Robot Knock-out Legend, or URKL, brought together 32 teams from more than ten countries for full-sized humanoid robots to trade strikes inside a cage. Every team started with the same base machine from Chinese robotics company EngineAI. The T800 stands roughly five feet eight inches tall, weighs between 165 and 187 pounds, and carries 29 joints built for human-like motion. Teams then added their own armor plating and tuned the software that decides how each robot moves, balances, and reacts.

Fights followed fairly simple rules, with the emphasis on landing effective hits, staying on your feet, and avoiding being clobbered. The robots would hurl punches, try to launch kicks, and recover quickly after being knocked flat on their backsides. The judges monitored clean hits and overall machine expertise. People expected the robots to be tough from the outset, but there was still some doubt about how they would fare once the real suffering began. White Eagle and Matador’s early bout changed everything. The White Eagle robot found an opening and delivered a powerful high kick that smashed right into Matador’s cranium. The head jerked jarringly back and forth many times before just falling loose. As Matador descended, the head swung loose and then totally detached.

The head holds all of the cameras and crucial sensors that let a machine to detect what is going on and react in a split second; without them, many robots would be walking dead, unable to track their opponents or stand upright. Nevertheless, Matador persisted.


Even with the head dangling from its cables, the black robot remained upright long enough to hurl a few more punches and kick out with its legs. There was no way the body would merely collapse into a heap. The torso and lower frame housed all of the control systems that kept the creature running, while the wide-angle radar and other body-mounted sensors provided the main computer with all of the information it need to keep going. A combination of super-strong posture control and shock-absorbing joints enables the machine to endure impacts while keeping its arms and legs in sync even after the head is removed. White Eagle saw an opportunity and seized it, winning when Matador eventually gave up and was unable to climb back up. The delighted robot then raised its arms in celebration, executing a brief victory dance that the audience enjoyed. Staff arrived to take the second robot from the ring.

Razer Hammerhead V3 HyperSpeed: two-minute review

The first thing I thought when I pulled the Razer Hammerhead V3 HyperSpeed gaming earbuds out of their box was “Wow, these are ugly.”

Not exactly the strongest first impression, but it’s unavoidable when each bud has a weird, bulbous design that gives them an appearance like a pair of obese AirPods. The shiny black plastic material looks cheap, as does the printed Razer logo on the outside, which (despite all the Razer Chroma branding on the box) is just a decal that doesn’t illuminate.

Hackers abuse ViPNet software to target Russian govt agencies

An advanced threat actor is abusing the update mechanism for the ViPNet private networking product suite to target Russian organizations, including government agencies.

Dubbed HelloNet, the campaign has been active since at least May, deploying a malicious payload that acts as a proxy and loader for additional malware.

According to Kaspersky researchers, HelloNet has impacted organizations in the government, energy, transport, education, and logistics sectors.

ViPNet update abuse

ViPNet is a family of Russian information-security products developed by InfoTeCS, providing VPN, endpoint, and network access protection, firewall, certificate management, centralized administration, and secure messaging and file transfer.

The tool is commonly used in Russia, where it is certified by the authorities for use in government and other regulated environments.

Due to its market reach in Russia, especially among high-value organizations, it has been targeted often by hackers. In April, 2025, Kaspersky reported that threat actors impersonated a ViPNet update in attacks.

In the latest campaign, attackers placed a malicious file (wtsapi32.dll, dubbed HelloInjector) inside the local ViPNet Update System directory to be sideloaded at system startup via the legitimate itcsrvup64.exe.

This DLL is the first-stage loader that injects into the svchost.exe process, granting next-stage payloads elevated privileges on Windows and persistence across reboots.

Kaspersky does not describe exactly how the attackers gained initial access to perform this file change, nor do they claim that ViPNet’s update infrastructure itself was compromised.

Malware toolset

HelloInjector runs its embedded payload, which Kaspersky named HelloProxy, in memory and contacts the command-and-control (C2) server to receive additional modules.

One of these modules is HelloExecutor, a backdoor that can execute commands and conduct network reconnaissance on the host.

A second one is HelloCleaner, a tool that removes ViPNet log data to hide the malicious activity.

Another implant called HelloBackdoor is Rust-based and supports uploading and downloading files, as well as command execution.

Kaspersky has tentatively attributed the campaign to an unidentified Chinese-speaking advanced persistent threat (APT) group.

However, the researchers stressed that the evidence is weak, relying primarily on an unused string referencing the Chinese website sina.com and a malware download mirror hosted by the University of Science and Technology of China.

As a result, they assign the attribution low confidence and do not rule out the possibility of a false flag operation.

The cybersecurity firm recommends thorough monitoring of systems running ViPNet software, particularly traffic passing through ports 5003, 5060 (HelloProxy), and 443 (HelloBackdoor).

Using AI makes people less likely to admit they don’t know something

Researchers found confidence increased even as accuracy fell

In 2026, AI still “hallucinates” and gives you wrong answers a good chunk of the time. Nevertheless, academics from French and Italian universities have found that access to AI advice suppresses critical thinking, making people more likely to confidently parrot incorrect information that the bot provided.

“For humans, the capacity to say, ‘I don’t know,’ is very important because it represents the recognition of the limits of our own knowledge,” said Valerio Capraro, associate professor at the University of Milano-Bicocca, in a phone interview.

“But now with AI, we can get an easy answer to virtually every question, so we wondered whether this would interfere with human capacity to say, ‘I don’t know,’ to suspend judgment.”

Capraro and co-authors Chiara Marcoccia (École Normale Supérieure) and Walter Quattrociocchi (Sapienza University of Rome) set out to see how access to AI advice affects people’s willingness to admit ignorance.

The title of their paper reveals their findings: “AI advice suppresses people’s willingness to say ‘I don’t know’, even when the advice is wrong and accuracy is incentivized.”

Capraro said that he and his colleagues designed a set of questions where large language models typically fail. In this instance, they asked study participants to answer questions about visual details in films, such as the color of the team’s uniform in Bend It Like Beckham or the vehicle Monica drives in Like a Cat on a Highway.

The researchers expected these sorts of details would be absent from most model training data, which was the case for the model used in the experiment (Step 3.5 Flash). They also tested recent frontier models (GPT-5.5, Claude Sonnet 4.6, Gemini 3.5 Flash), which missed the vehicle question but often got other details correct.

They used Step 3.5 Flash because it was usually wrong, as explained in the paper, so any reduction in judgment could not be explained away as sensible delegation to a reliable tool.

“We divided human participants into two groups,” explained Capraro. “One group had to answer these questions without AI advice, and another group could ask the AI for advice. What we found is that in the baseline, 44 percent of people responded that they didn’t know the answer, so they suspended judgment. With AI advice, only three percent did so. So the judgment suspension collapsed.”

Capraro said that even more interestingly, accuracy collapsed when AI help was available. In other words, they trusted AI’s answer more than their own.

“In the baseline, 27 percent of people gave the correct answer,” he said. “With AI advice, only nine percent of people gave the correct answer. So some would-be correct people asked for AI advice and became wrong.”  

Also, access to AI advice made people more confident that they were correct. The baseline level was 30 percent, he said, but with AI help, confidence rose to 76 percent. They believed the bots, despite the possibility of hallucinations.

“So basically people became much worse – the accuracy was only one third – but they were twice as confident,” he said.

The researchers also conducted the experiment with monetary incentives, which helped a bit. Willingness to suspend judgment and admit ignorance rose from 3 percent to 8 percent and accuracy rose from 9 percent to 16 percent but was still below the baseline of 44 percent and 27 percent respectively.

While the researchers chose questions about film trivia, they contend their findings can be generalized across other domains.

Capraro said that he believes this is an issue that needs to be dealt with at a societal level through AI literacy and education policy initiatives. “Of course model providers should try to help, but I would imagine that the incentives are not very much aligned,” he said. “A much more promising approach would be at the educational level.”

“I’m very much concerned for children, because adults have learned critical thinking. But for children who basically are born with these systems, the risk is that they don’t even learn the basic critical skills.” ®

Remembering The Zilog Z80 As It Turns Fifty Years Old

Published

on

Perhaps the saddest thing about the Zilog Z80 is that this humble 8-bit microprocessor wasn’t allowed to live until its 50th birthday. This, fortunately, doesn’t prevent people like [David Oberhollenzer] from reminiscing on this influential processor and what it means to them personally.

First released in July of 1976, this humble 8-bit miracle would go on to power not just a range of home computers, but also be found in everything from industrial controllers to arcade systems. Despite this success, the new owner of Zilog — Littelfuse — decided to put an end to this winning streak in 2024 for the stand-alone processor and its peripherals.

Although the original Z80 ecosystem ceased production, this didn’t prevent hobbyists from creating new operating systems for it, let alone entire new development toolchains, or demonstrate multitasking on the Z80.

Meanwhile, the Z80 architecture is still very much alive and kicking, such as in the form of the eZ80 SoC in the TI 84+ CE calculator that [grubbycoder] ported Sonic 2 from the Z80-based Sega Master System.

Among all of this modern-day Z80 goodness, we also have a few gems from the past to admire, such as the OS that Zilog made for this architecture in the form of Z80-RIO, which was sadly not as successful as the hardware.
