Patch for Windows Defender 0-day could allow attackers to fill hard disk

Patch for Windows Defender 0-day could allow attackers to fill hard disk

fivenewscrypto    juillet 10, 2026   

A patch Microsoft released on Wednesday to fix a zero-day vulnerability in its Defender security engine may cause Windows machines to write files large enough to completely consume available disk space, the researcher who discovered the flaw said.

RoguePlanet, tracked as CVE-2026-50656, came to public notice in June when NightmareEclipse, the pseudonymous name used by a researcher, disclosed it along with code for exploiting it. The vulnerability allows remote attackers to gain administrative control of Windows 10 and Windows 11 machines, even when real-time protection has been disabled. Over the past few months, the anonymous researcher has published a handful of other zero-days that have sent Microsoft scrambling to develop patches.

Writing files of unlimited size

Microsoft said Wednesday that it patched RoguePlanet with an update to the Microsoft Malware Protection Engine, which is used by the Defender antivirus app. The fix will automatically be downloaded and installed without users having to take any action. Wednesday’s update also includes “defense-in-depth updates to help improve security-related features.”

Humanoid robots controlled by surgeons did world-first operation on live pigs

Humanoid robots controlled by surgeons did world-first operation on live pigs

fivenewscrypto    juillet 10, 2026   

Humanoid robots have surgically removed the gallbladders from living animals in an unprecedented medical experiment—but not as autonomous machines capable of replacing human doctors. Instead, skilled human surgeons remotely controlled the robots’ movements in a new example of human-robot teamups.

The teleoperated humanoid robots completed two minimally invasive surgeries by removing gallbladders from live pigs during a preclinical trial that was published in the journal Nature. If this approach eventually proves clinically ready for human patients, surgeons could use such humanoid robots to remotely perform robotic-assisted surgical care in smaller hospitals and clinics that lack the resources to install specialized but expensive surgical robots.

“It's a fraction of the cost and it takes a fraction of the space in an operating room,” said Shanglei Liu, an assistant professor of surgery at the University of California San Diego School of Medicine, in an interview with UC San Diego Today. “So it’s easy to deploy, anywhere from rural areas, to the battlefield, and even to space.”

Conspiracies and regrets abound in Dune: Part Three trailer

Conspiracies and regrets abound in Dune: Part Three trailer

fivenewscrypto    juillet 10, 2026   

We haven't seen much footage to date for Denis Villeneuve’s Dune: Part Three, other than the broody and haunting extended teaser Warner Bros. dropped in March. But now we've got a shiny new trailer jam-packed with tantalizing hints of what to expect, and plenty of Easter eggs to delight avid book fans.

(Spoilers for first two films in the franchise below.)

As previously reported, in 2021’s Dune, we first met Frank Herbert’s iconic anti-hero, Paul Atreides (Timothée Chalamet). That film culminated in the brutal defeat of House Atreides by rival House Harkonnen, with Paul and his mother, Lady Jessica (Rebecca Ferguson), fleeing to the desert and taking refuge among the Fremen. Among them is Chani (Zendaya), whom Paul has been seeing in visions all along.

Judge rejects Kalshi attempt to override New York state gambling laws

Judge rejects Kalshi attempt to override New York state gambling laws

fivenewscrypto    juillet 10, 2026   

Kalshi lost an attempt to override New York's state gambling laws yesterday, with a federal judge rejecting the prediction market operator's request to prevent enforcement of the rules.

Kalshi is appealing the decision to a higher court. This is one of numerous cases in which judges must decide whether state laws are preempted by federal regulation of prediction markets.

New York Governor Kathy Hochul and Attorney General Letitia James issued a joint statement on the ruling today. “New York’s gambling laws are designed to protect consumers," they said. "Kalshi tried to ignore them. Yesterday, they lost in court. We will continue to hold all gambling platforms accountable to the law—and that includes prediction markets.”

Google pays $250K for Linux vulnerability allowing guest VM escapes

Google pays $250K for Linux vulnerability allowing guest VM escapes

fivenewscrypto    juillet 10, 2026   

A Linux vulnerability that allows untrusted virtual machines to gain root access to host machines is one of two high-severity flaws to surface this week in the open source operating system.

The vulnerability resides in KVM, which is, in essence, a virtual machine app included in the kernel of many Linux distributions. The vulnerability, tracked as CVE-2026-53359, allows guest virtual machines—such as those used in cloud platforms to isolate one user’s instance from the host OS and other user instances—to break out of that container.

Januscape: A threat to cloud platforms

The vulnerability affects KVM running on both AMD and Intel processors. It exploits bugs residing in the KVM guest-side, the portion of the VM that consists of only resources like the OS or drivers present in the guest VM, rather than resources present on the host machine. The threat went unnoticed in the Linux kernel for 16 years.

Aussie gov't tells volunteers to throw out thousands of functioning test routers

Aussie gov't tells volunteers to throw out thousands of functioning test routers

fivenewscrypto    juillet 09, 2026   

Last week, thousands of SamKnows routers were bricked after a government program ran its course.

In 2020, as part of a program conducted by the Australian Competition & Consumer Commission (ACCC), the Australian government's chief competition regulator, thousands of volunteers received routers to help test and report on the typical speed and performance of broadband plans in Australia. (More specifically, the Measuring Broadband Australia (MBA) program targeted fixed-line broadband services provided over the NBN, Australia's government-owned wholesale open-access broadband network, as well as services delivered over other access networks.)

According to the final report that the ACCC distributed, the routers are whiteboxes that were “supplied by SamKnows” and that “perform tests to measure internet performance using test servers maintained by SamKnows and hosted in Australia.”

TikTok users don't have as much agency over their FYPs as they think

TikTok users don't have as much agency over their FYPs as they think

fivenewscrypto    juillet 09, 2026   

TikTok's For You Page (FYP) is the default home screen for users of the video-sharing platform. It's a personalized, algorithmically driven content feed, but the approach differs from other social media in that TikTok's algorithm relies heavily on implicit signals—such as how long users watch particular videos—as well as explicit signals such as likes or follows. And generally, that algorithm does remarkably well at predicting which videos will interest particular users.

But some users have voiced concerns that TikTok's almighty algorithm doesn't seem to incorporate negative feedback very well. Even when they don't watch a suggested video or click the "not interested" feature, they keep seeing those videos on their FYP. Northeastern University computer scientists put those suspicions to the test. According to their recent paper, the engagement signals do have an effect, but only temporarily. Then the algorithm gradually relapses unless a user consistently gives the same feedback over and over again.

The research group specializes in "algorithm audits," co-author Piotr Sapiezynski told Ars, to better understand online platforms: "how they work, how they fail, when they fail, how they harm individuals and societies." In this case, he and his co-authors wanted to take a closer look at user agency after hearing multiple anecdotal reports from TikTok users that their negative feedback—responding to prompts by indicating they aren't interested or want to see less of a certain kind of video—doesn't seem to remove those posts from their FYP. "On the other hand, it's unclear why the platforms would offer it, if it doesn't work," said Sapiezynski.
