These models can rapidly answer questions, source information online, assist users with specific tasks and produce text tailored for specific purposes. https://techxplore.com/news/2026-07-hidden-prompts-false-memories-ai.html Security Sun, 19 Jul 2026 10:20:01 EDT news703427290 So-called deepfakes, that is, images and videos generated with the help of artificial intelligence, are becoming increasingly difficult to detect. An international research team from the University of Tokyo and the Max Planck Institute for Informatics in Saarbrücken, Germany, has developed a method that identifies manipulated videos more reliably than previous approaches—not by searching for visual artifacts, but by analyzing the naturalness of facial expressions. In tests on established benchmark datasets, the approach achieved an average detection accuracy of more than 95 percent and successfully identified manipulations that caused many existing detectors to fail. https://techxplore.com/news/2026-07-facial-movement-analysis-deepfake-videos.html Security Thu, 16 Jul 2026 11:20:09 EDT news703417834 While security systems based on pseudo-random number generators (PRNGs) have been developed to secure information use, they produce sequences that are not truly random and suffer from inherent vulnerabilities and security breaches. To overcome these limitations, a true random number generator (TRNG) that exploits diverse sources of physical entropy has emerged as an alternative technology. https://techxplore.com/news/2026-07-driven-random-generator-image.html Hi Tech & Innovation Mon, 13 Jul 2026 08:00:01 EDT news703144518 Many digital users rely on Virtual Private Networks (VPNs) to combat security threats, allowing the application to view, intercept and handle all user traffic in return for hiding identifying information from third parties. Yet a new mobile VPN security testing framework—MVPNalyzer—found many popular VPNs breach user trust, according to a University of Michigan Engineering study. https://techxplore.com/news/2026-07-mobile-vpn-strong-advertised.html Internet Tue, 07 Jul 2026 13:07:10 EDT news702648411 An AI flaw that can be found today in one model could be quietly replicated across dozens of products and services built on the same underlying technology. Until now, the AI community has lacked a formal pathway to report those flaws, alert affected vendors and coordinate a response. Researchers at Carnegie Mellon University's Software Engineering Institute (SEI), alongside collaborators from academia and industry, helped build one. Flaw Reporting for AI (FLARE-AI) is a new open-source platform that lets anyone report an AI vulnerability and route it to developers, vendors and government agencies equipped to act. https://techxplore.com/news/2026-07-critical-gap-ai-platforms.html Security Mon, 06 Jul 2026 13:40:06 EDT news702562762 In the last year or so, artificial intelligence companies have rolled out a spate of web browsers equipped with AI agents. A user might ask one of these agents to plan a vacation, and it will open browser tabs to research routes and restaurants, then make reservations and add events to the user's calendar. How well it does any of this varies. https://techxplore.com/news/2026-06-agentic-ai-browsers-major-cybersecurity.html Internet Fri, 03 Jul 2026 10:00:01 EDT news702053575 Researchers from North Carolina State University and Rice University have created a nontoxic, stretchable battery that operates by extracting moisture from the ambient environment—even in climates as dry as the desert. The batteries could be useful in Internet of Things (IoT) applications ranging from wearables to advanced surveillance monitors with built-in kill switches.

It may also be learning who gets listened to. A new study from researchers at the University of North Carolina at Chapel Hill found that large language models, the technology behind popular AI chatbots, change the way they communicate depending on the social role they're assigned in a conversation. When cast as a "boss," they adopt different language patterns. When positioned as a subordinate, they become more accommodating, sometimes in ways that could undermine safety. https://techxplore.com/news/2026-07-ai-behavior-authority-risky.html Security Wed, 01 Jul 2026 13:40:12 EDT news702131461 Today's antipersonnel land mines are small and often have plastic casings that standard metal detectors cannot register. Geophysical techniques such as ground-penetrating radar, magnetometry and electromagnetic induction are significantly less effective with plastic mines than with those made of metal. https://techxplore.com/news/2026-06-drone-mounted-camera-plastic-landmines.html Engineering Tue, 30 Jun 2026 12:00:12 EDT news702038641 Humans have been successfully trained to spot AI-generated faces in a study led by researchers at the Australian National University (ANU) Emotions and Faces Lab.

To descramble encrypted data, devices or accounts need access to randomly generated cryptographic keys, unique, randomly generated sequences of binary code, letters or numbers that are essential for encrypting or decrypting data. https://techxplore.com/news/2026-06-orbit-torque-hardware-random-keys.html Hardware Thu, 18 Jun 2026 11:40:01 EDT news700999720 Researchers from Tokyo Metropolitan University have created a new paradigm for identifying online phishing campaigns. Their new system, PhishLumos, is triggered when links show signs of concealing information and looks for clues in the "infrastructure" of the website to uncover the whole campaign of which the site is only a tiny part. Real-world testing showed detection that was eight days faster than an expert's, with 190,000 URLs detected over six months. https://techxplore.com/news/2026-06-phishlumos-phishing-infrastructure-urls-months.html Security Sat, 13 Jun 2026 05:29:42 EDT news700547363 A new kernel (core program) within an operating system gives researchers a cleaner view of what's happening inside a processor.

They can take control of your computer, delete files and disappear without a trace. However, FIU cybersecurity researcher Weidong Zhu has discovered a way to transform a computer's storage chip into an additional tool for cyber defense. Working with collaborators at the University of Florida, Zhu created a system that makes data on these chips last longer—extending the lifespan of your files in the critical window after your computer is compromised. The work is published in the journal Proceedings of the 2025 ACM SIGSAC Conference on Computer and Communications Security. https://techxplore.com/news/2026-06-retention-aware-storage-chip-cybersecurity.html Security Mon, 01 Jun 2026 16:00:03 EDT news699548041 The security of modern communications heavily relies on systems that can rapidly and reliably verify users and the devices they are using.
