BeyondTrust warns of critical flaws in remote access software

BeyondTrust warned customers to patch two critical security flaws in its Remote Support (RS) and Privileged Remote Access (PRA) software that could allow attackers to bypass authentication.

The first vulnerability, tracked as CVE-2026–40138, affects the company’s RS remote desktop and assistance platform (versions 25.3.2 or earlier) and the PRA enterprise cybersecurity solution (versions 25.3.2 or earlier). This vulnerability stems from an improper authentication weakness in the authentication subsystem, and successful exploitation enables attackers without privileges to bypass access controls and access targeted appliances, including accounts with elevated privileges.

The second one (CVE-2026–40139) patched this week stems from improper processing of BeyondTrust RS authentication requests, enabling unauthenticated remote attackers to gain unauthorized access to vulnerable instances.

Microsoft testing new Cloud Rebuild Windows 11 recovery feature

Microsoft has begun testing the Cloud Rebuild recovery feature in the latest Windows 11 Insider Preview builds released for users in the Experimental channel.

First introduced at the Ignite developer conference in November 2025, Cloud Rebuild is a tool that can remotely trigger a complete system reinstall from the cloud for Windows 11 devices experiencing persistent problems or that have become inoperable.

“We’re introducing Cloud rebuild, a new recovery option that restores a Windows 11 PC to a clean, known-good state by performing a full OS reinstall, even when Windows won’t boot,” Windows Insider Communications Lead Stephen Lines said on Monday.

Legendary former Tekken boss says people don’t ‘properly evaluate’ Hidetaka Miyazaki’s ‘remarkable’ FromSoft career

“From that perspective, I can say that Dark Souls didn’t suddenly become a massive success overnight,” Harada said. “It was the result of everything Miyazaki and his team had built up through their previous titles.”

According to Harada, the acclaim that FromSoft enjoys feels like “almost complete reversals in attitude” compared to “the days when [Miyazaki] and his team were struggling the most.” It was a contributing factor to his own exhaustion with people who he says can only judge a game’s merits “by saying things like, ‘That title cost X billion yen to make and sold Y million copies.’”

Structural insight into the mechanism of bacterial pili retraction

Every year bacteria kill more than a million people worldwide through infections that no longer respond to antibiotics. In many cases, why those bacteria are so hard to stop comes down to their uniquely powerful structure.

On the surfaces of many disease-causing bacteria, fibers thousands of times thinner than a human hair bristle, acting like biological grappling hooks. These fibers help bacteria latch onto body tissue, build biofilms, which are sticky bacterial communities that antibiotics struggle to penetrate, and reel in fragments of DNA from their environment, including genes that help them resist drugs.

Now, scientists have solved a key mystery about how those hooks work. A new study, published in the Proceedings of the National Academy of Sciences, reveals the molecular mechanism behind one of the most powerful mechanical actions in all of biology, the reeling in of tiny surface fibers called type IV pili.

New brush test detects oral cancer in one hour

A paper published in the journal Biomarker Research by a cross-university team led by Queen Mary University of London researchers validates the use of a noninvasive brush biopsy test that can detect oral cancer within one hour.

This test could revolutionize oral cancer detection and prevent more than 90% of unnecessary harmful scalpel biopsy procedures. These can be very painful, lead to infection and, in some areas of the mouth, such as the gum, are hard to carry out and may damage the underlying tooth and bone structure.

Oral cancer is a growing global killer. According to Global Burden of Disease data, lip and oral cancer are among the world’s most rapidly increasing causes of early death. More than 10,000 people in the UK were diagnosed with oral cancer last year, according to the charity Mouth Cancer, and 3,637 people died. Worldwide, it affects 650,000 people a year. Risk factors include tobacco use and smoking, alcohol, infection with the HPV virus, and sun damage. Unfortunately, more than half (53%) of all mouth cancers are diagnosed in stage IV, when the cancer is at its most advanced.
