Decades-Old Bash Tricks Expose AI Coding Agents To Supply Chain Attacks

Slashdot reader wiredmikey writes: AI security researchers have uncovered a structural security flaw dubbed GuardFall that allows decades-old Bash shell tricks to bypass safeguards in most open source AI coding agents. By exploiting shell behaviors such as quote removal and variable expansion, attackers can hide malicious commands in repositories, README files, Makefiles, or other content consumed by AI agents. If executed - particularly in auto-approve or CI environments-the commands can steal credentials, compromise developer systems, or enable software supply chain attacks. According to researchers at Adversa AI, the 11 popular open source AI coding agents tested, only one successfully blocked all of the Bash trick techniques.

What Is a Quantum Computer Good For? Absolutely Nothing - Yet

The Verge argues that researchers "have made genuine progress in quantum computing - it's just been largely incremental and too esoteric to immediately capture the public's imagination." And there are predictions that quantum computers will finally do something useful as soon as 2028: The drama can overshadow the real progress in quantum computing... Researchers have improved the qubits themselves, so they hold onto information longer. When they hold onto information longer, you can fit in more operations and do more complicated algorithms. Last November, Andrew Houck of Princeton University and his colleagues reported that they'd made a superconducting qubit that can hold onto information three times longer than the previous record holder... And in the last two years, researchers have made substantial strides in what's known as quantum error correction... In addition, researchers have developed algorithms to correct errors while the quantum computer operates... Microsoft claimed, which experts dispute, that it made an object made of electrons known as a Majorana particle [which should make fewer errors and be easier to scale up]... "We 100 percent stand behind our results. We stand by our roadmap," Microsoft's quantum lead, Chetan Nayak, responded in an interview with The Verge. In an email statement, he added that Microsoft's "papers do show that we are creating and controlling Majorana [particles]... Microsoft's supporting evidence is unconvincing [according to [Henry Legg, a physicist from the University of St. Andrews and a longtime Microsoft critic]Rnqyq. What it claimed as evidence of a Majorana particle, he says, could actually be due to quantum dots forming in its device. Quantum dots are electron-containing objects that are not useful for Microsoft's quantum computer. It also bases its claim on data from a single device, says Legg. He wants to see Microsoft replicate the results in multiple chips. "If you repeatedly try and find Jesus in your toast, eventually you'll find Jesus in your toast," he says. "But that one piece of toast doesn't mean you had some kind of epiphany." "While we appreciate the religious fervor, our data maintains the strength and consistency of our roadmap, as we have for the past several years across previous milestones. We look forward to delivering the world's first quantum machine and sharing the energy of our achievements with the world," wrote Nayak in response. Past spurious work from Microsoft-affiliated researchers adds to the doubt. In 2021, the journal Nature retracted an article from Microsoft-affiliated researchers in which they'd claimed strong experimental evidence that they'd created a Majorana particle. "Even hopeful experts have varying opinions about when a quantum computer will demonstrate something useful," the article acknowledges. But quantum computing lecturer Eleanor Crane of King's College London predicts researchers will have demonstrated a useful scientific simulation on a quantum computer by 2028.

Startup Targets Datacenters With 3D-Printed Nuclear Reactor Module

Startup Ampera has unveiled what it calls the first 3D-printed nuclear reactor module, built around a silicon-carbide core and pressure vessel designed for a thorium-based microreactor. The company says future systems could deliver 15 or 30 megawatts for up to 30 years without refueling. When The Register asked about availability, their spokesperson said: "We expect the power generation portion of the system to be available as early as 2027, with the nuclear module being available to customers about 2030 based on regulatory approval." From the report: Founder and CEO Brian Matthews revealed the prototype microreactor, which features a fully 3D-printed silicon carbide reactor core and pressure vessel. "This next-generation nuclear core and pressure vessel sets the foundation for factory-built, mass-produced nuclear energy," Matthews said. "The advanced technology and additive manufacturing used demonstrate a clear commercial path for new nuclear technology coming to market in an accelerated manner." His company is developing a subcritical, solid-state, factory-built thorium-based nuclear reactor. Subcritical means the fuel cannot sustain a nuclear chain reaction on its own, which prevents a runaway power excursion. Ampera uses "solid-state" to describe a design with solid rather than liquid fuel. The proposed fuel uses tristructural isotropic, or TRISO, particles, consisting of a fuel kernel containing thorium, surrounded by multiple ceramic and carbon layers. [...] "Thorium is the future for ultra-safe, clean power production," Matthews said at the time. "By producing TRISO thorium kernels in the United States, we can ensure ample access to the needed fuel supply as we scale up and also minimize price volatility risk." Ampera also describes the heart of the reactor as as a spherical monolithic gyroid core. A gyroid, as far as we can fathom, is a complex shape that provides a massive surface area relative to its volume, making it well-suited for heat transfer. Its complexity makes it difficult to produce using conventional manufacturing methods, which is where additive manufacturing comes in. The core is 3D-printed using silicon carbide and designed to operate for up to 30 years without refueling, the firm claims. Ampera says its planned systems will provide 15 or 30 MWe, depending on the configuration, enough to supply a typical datacenter. Larger configurations are planned. Matthews said that his company expects to be the first to industrialize factory-built nuclear power with near-term deployment timelines.

ReactOS implements very first NT6 system call

A fairly big moment for the ReactOS project: it has just received its very first system call from NT6. The system call that has been added is NtGetCurrentProcessorNumberEx, which is used for returning the processor number of the logical processor that a caller is running on. It's unclear how long it will take ReactOS to become compatible with Windows Vista software, but it took Microsoft around half a decade to develop Vista after the release of XP and marked a major upgrade, even if it didn't land well with users at the time. ↫ Paul Hill at Neowin It's a milestone for sure, but not one that's going to make a huge difference for ReactOS at this moment in time. Still, it's a sign of things to come, even if the very nature of the ReactOS project means that whatever things are coming tend to take a while to arrive.

Microsoft settles centuries of religious debate by providing clearest definition of hell to date: Windows with a website-based shell running only Copilot

For how often people invoke it, the concept of "hell" in Christianity is remarkably vague and nebulous, as both the Old and New Testament barely go into detail about the concept. As such, I'm glad Microsoft has now given us a clear vision of hell and what, exactly, it looks like, ending centuries of denominational disagreements. Microsoft is currently selling the idea of Windows and Copilot as two separate things: an OS and an assistant riding along on top of it. However, a leaked video shows Project Aion, an internal prototype where Copilot doesn't just sit inside Windows, it becomes Windows, swallowing the Start menu, the taskbar, and three decades of desktop conventions in the process. The footage is reportedly two years old, so Aion is most likely dead by now. But it's the clearest look yet at how far Microsoft was willing to take its agentic AI ambitions. ↫ Alfonso Maruccia at Techspot Everything about this is dreadful. Obviously replacing the entire shell with "AI" nonsense is the main crime against usability here, but on top of that, this new shell is all just websites, all the way down, so everything is slow and stuttery. Since this runs on something called "Win3", which appears to be a very minimal, stripped-down version of Windows intended to only run the Edge browser engine, you can't run Win32 applications. If you do try to run a Win32 application, it will load the application in a remote virtual machine running in the cloud, which I;m sure does wonder for performance, responsiveness, and latency. We can all thank the lord this project is two years old and most likely cancelled by now, but we have no way of knowing if Microsoft is still intending for this to be the future direction of Windows. Since people don't want to use "AI" of their own volition, it only makes sense in the technology industry's sick, twisted mind to force people into using "AI" with efforts like this. Consent has never been Silicon Valley's strength, after all. At the time of writing, Microsoft is 225 billion dollars in the red on "AI", so I wouldn't be surprised if attempts to replace the regular Explorer shell with something "AI"-based is still very much on the table in Redmond.

Vulkan-netbsd brings Vulkan to NetBSD

NetBSD is the only BSD without a Vulkan stack (Mesa and Lavapipe), but that's about to change. The effort to bring Vulkan to NetBSD is now in beta, with prebuilt binaries coming soon. Mesa configures, compiles, links, installs, and registers the Lavapipe software Vulkan driver on NetBSD 10.1 amd64, against LLVM 19.1.7. The driver (libvulkan_lvp.so, ~17 MB) installs into /usr/pkg/lib, and its ICD manifest (advertising Vulkan API 1.4) installs into /usr/pkg/share/vulkan/icd.d/, so a Vulkan loader on the system can discover it. ldd resolves every dependency cleanly. The entire process - environment setup, dependency builds, the Mesa build, and installation - is automated end to end and reproducible on a fresh install. ↫ vulkan-netbsd GitHub page It's important to note that the next step in the process is to port the Vulkan loader, which is required to actually run Vulkan applications. This entire effort is still ongoing and seems to be handled mostly by Dean Howell alone, so expect breakage and incomplete documentation as development progresses. Still, this is a hugely important effort, and seeing it this far along is great news.
