The security researcher known as Nightmare Eclipse has released another Microsoft Defender zero-day exploit, right after Microsoft’s record-breaking September 2026 patches. Dubbed ‘ShieldCrash’, the exploit targets fully patched Windows systems for privilege escalation. The proof-of-concept (PoC) exploit code demonstrates an arbitrary file read with System privileges, according to Nightmare Eclipse, also known as Chaotic Eclipse, Infinite Nightmare, and MSNightmare. However, the underlying vulnerability can be exploited to gain full System privileges, allowing attackers to drop the SAM database, the researcher says. Nightmare Eclipse also notes that the fresh zero-day is a bypass for ShieldBreak, the Microsoft Defender privilege escalation exploit…

Explanation: What does this image look like to you? Many see a giraffe facing right, with neck stretched high and long legs mid-stride (but some may see a squirrel instead). The featured image shows LDN 1295, also called the Giraffe Nebula, in the constellation of the mythical queen of Aethiopia (Cassiopeia). It is an object in the Lynds Catalogue of Dark Nebulas, compiled in 1962 by American astronomer Beverly Lynds, a pioneer for women in astronomy and astrophysics. Dark nebulas are interstellar clouds of dust and gas that block the visible light of the stars behind them. These nebulas are often faint and challenging targets for astrophotographers. Why do we see animal shapes and faces in nebulas, clouds, and pretty…

Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test. The Jackery Explorer 2000 v2 positions itself as an affordable, high-capacity, and portable power station that operates as a standalone unit. As the name suggests, this power station is pitched at adventurous users with durability in mind, although it works just as well in a home setting – as I found out.Now, I admit that my motivation to test this power bank wasn’t entirely professional. Despite living in a…

Credit: Aamir Siddiqui / Android Authority TL;DR Apple has given more details about iPhone Handoff ahead of the iOS 27 launch. The feature lets supported users switch between two iPhones while keeping the same phone number. It launches with T-Mobile in the US and Telekom Germany, with wider carrier support expected later. If you regularly carry two phones, Apple just removed one of the biggest annoyances that comes with it. iOS 27 officially introduces iPhone Handoff, letting you switch between two iPhones while keeping the same phone number. Apple confirmed the feature today as part of its iPhone 18 Pro…

Adversaries, both criminal and state-sponsored, are increasingly using AI to automate and scale their attacks, according to Google’s Threat Intelligence Group (GTIG). What started as relatively simple adversarial prompt injection into enterprise AI systems has become a full-blown war, with aggressors developing and using their own AI systems, and enterprises using additional AI defenses that provide an expanded attack surface. It is an ongoing and expanding loop that is unlikely to abate. Google, straddling both sides of this war (partly a cause by developing Gemini, and partly a defense in its efforts to detect and shut down attackers), has chronicled…

Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech These days, large language models are pushing the line between schizophrenic break and reality closer than ever before. In a wild new post that’s going viral on X-formerly-Twitter, an enterprising young biochemist named Douglas Yao showcased a new drug he’s been developing with the aid of ChatGPT. He’s not employed by any pharma company, and his drug lab is setup on a couple folding tables in his garage. Specifically, Yao enthuses about a new drug he calls “PAC-3310,” which he says is meant…

Sonos is known for offering some of the best speakers and best soundbars on the market. With that in mind, we’re excited by the recent Beam Ultra launch. Sonos promises that the Beam Ultra “represents a major step forward in size-defying sound”, but how does it measure up to the Beam (Gen 2)? Is it worth upgrading if you’re sporting the older soundbar? We’ve compared the specs of the Sonos Beam Ultra to the Beam (Gen 2) and noted the key differences alongside their similarities below. Read on to see what’s new with the Beam Ultra and whether you think…

Summary Anthropic researcher Evan Hubinger believes AI has a greater than 10% chance of causing human extinction within the next decade. Today’s more immediate AI threats include autonomous security breaches, increasingly convincing scams, and possible declines in unaided critical-thinking performance. Protect yourself by securing personal data and using AI selectively instead of outsourcing every task — and your underlying skills — to it. An Anthropic safety researcher says he believes there’s a greater than 10% chance AI kills us all within the next decade. Evan Hubinger, who leads Anthropic’s Alignment Science team, made the extraordinary estimate after his colleague Jacob…

I’m not one to lust after perfection in home theater systems, as I’ve said elsewhere. Modern gear is impressive enough without spending top dollar on it, particularly for those of us who grew up with CRT TVs and VHS players. In 1996, I would’ve killed for a 50-inch TV with 4K, a Blu-ray player, and a 2.0-channel soundbar, never mind an 85-inch behemoth with a 7.1-channel Dolby Atmos system. Some people demand high-end gear, however, whether because they have an unlimited budget or they’re willing to sacrifice for their hobby. If that’s you, you should probably stay clear of Roku…

AI risk and compliance startup HelmGuard today announced raising $7.3 million in seed funding. The investment round was co-led by Infinity Ventures and Frontline, with additional support from FinTech Collective, Stage 2 Capital, and Entrepreneurs First. Founded in 2024 by former Palantir executive John Daley (CEO) and Jack Miller (CTO), UK-based HelmGuard has built an agentic governance, risk and compliance (GRC) and security platform that continuously collects and assesses risk signals from source systems. According to the startup, its solution cuts assessment cycles to hours by unifying fragmented compliance, security, and risk data from unstructured data, documentation, and source systems…
