Google fixes Chrome zero-day with in-the-wild exploit (CVE-2026-5281)

Google has fixed 21 vulnerabilities affecting its popular Chrome browser, among them a zero-day (CVE-2026-5281) with an in-the-wild exploit. About CVE-2026-5281 As per usual, information about the fixed zero-day is limited, and there’s no details about the exploit (or how/if it’s being used by attackers). CVE-2026-5281’s official description says it’s a use-after-free (UAF) vulnerability in Dawn, an open-source and cross-platform implementation of the WebGPU standard that’s used in Chromium and Chromium-based browsers. The vulnerability affects … More → The post Google fixes Chrome zero-day with in-the-wild exploit (CVE-2026-5281) appeared first on Help Net Security.

Egnyte expands Content Cloud with AI Governance and built-in Assistant

Egnyte has announced two major additions to the Egnyte Content Cloud: AI Safeguards, which give organizations granular control over how AI interacts with sensitive content, and an AI Assistant that acts as a built-in collaborator across Egnyte workspaces. AI Safeguards As organizations accelerate AI adoption, ungoverned access to sensitive content by AI systems represents a growing and underappreciated risk. Egnyte’s AI Safeguards addresses this directly by embedding AI controls into the same platform that already … More → The post Egnyte expands Content Cloud with AI Governance and built-in Assistant appeared first on Help Net Security.

Mimecast makes enterprise email security deployable in minutes

Most organizations running Microsoft 365 rely on native email controls as their primary line of defense. According to Mimecast research, 38% of organizations depend exclusively on those native controls for collaboration security, and 64% say those controls are insufficient against the threat landscape. Ranjan Singh, Chief Product and Technology Officer at Mimecast, outlines how the company’s API-based approach delivers protection on par with a traditional Secure Email Gateway without requiring infrastructure changes, and why that … More → The post Mimecast makes enterprise email security deployable in minutes appeared first on Help Net Security.

Financial groups lay out a plan to fight AI identity attacks

Generative AI tools have brought the cost of deepfake production low enough that criminals and state-sponsored actors now use them routinely against financial institutions. A joint paper from the American Bankers Association, the Better Identity Coalition, and the Financial Services Sector Coordinating Council lays out the scale of the problem and calls on federal and state policymakers to act across various areas. Deepfake incidents in the fintech sector increased 700% in 2023 compared to 2022. … More → The post Financial groups lay out a plan to fight AI identity attacks appeared first on Help Net Security.

Malware detectors trained on one dataset often stumble on another

Machine learning models built to catch malware on Windows systems are typically evaluated on data that closely resembles their training set. In practice, the malware arriving on enterprise endpoints looks different, comes from different sources, and in many cases has been deliberately obfuscated to evade detection. A study from researchers at the Polytechnic of Porto tests what happens when that gap is made explicit, and the results have direct implications for organizations relying on static … More → The post Malware detectors trained on one dataset often stumble on another appeared first on Help Net Security.

DNA robots could deliver drugs and hunt viruses inside your body

DNA robots are emerging as tiny programmable machines that could one day deliver drugs, hunt viruses, and build molecular-scale devices. By borrowing ideas from traditional robotics and combining them with DNA folding techniques, scientists are creating structures that can move and act with precision. These robots can be guided using chemical reactions or external signals like light and magnetic fields.

These “smart” crystals bend and snap back when hit with light

Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned depending on the light’s intensity and color. Researchers say these materials act more like adjustable systems than simple switches. The finding could lead to a new generation of light-powered sensors and devices.
