Microsoft’s own documentation and Insider notes make an unusually blunt admission: Windows 11 now includes an opt‑in set of experimental agentic features that let AI agents act on a user’s behalf—opening apps, clicking UI elements, reading and writing files in common folders—and Microsoft warns...

Microsoft quietly acknowledged what security researchers have been warning about: the new experimental “agentic” layer in Windows 11—the set of background AI agents that can act on a user’s behalf—can hallucinate and create real, novel security risks, including the ability for malicious content...

Microsoft’s blunt advisory that Windows 11’s experimental “agentic” AI features introduce novel security risks has refocused a long-running debate about where convenience ends and vulnerability begins — and it arrived not as a marketing footnote but as a front‑page safety notice built into...

Microsoft quietly shipped an experimental “agentic” layer into Windows 11 and, unusually for a vendor, warned up front that those agents may hallucinate and introduce novel security risks — including a new class of attacks Microsoft calls cross‑prompt injection (XPIA). Background / Overview...

Microsoft’s own documentation now admits what security researchers have long feared: the new agentic features in Windows 11 — agents that can act on your behalf, click and type inside apps, and read and modify local files — come with real, material security risks, including the possibility that...

Perplexity’s Comet and the cascade of disclosures this year have exposed a stark truth: agentic AI browsers that act on user behalf dramatically expand the attack surface of everyday web browsing, and the technical and legal fallout shows the industry is still scrambling to catch up. Background...

Microsoft’s own documentation for Windows 11 now contains an unusually blunt security caveat: the new experimental “agentic” AI features that let the OS act on your behalf are powerful, but they also create novel attack surfaces that administrators and consumers must treat as security decisions...

Microsoft’s latest agentic push for Windows 11 has a stark, unusually candid caveat: enable the new AI agent features only if you understand the security implications, because a compromised or manipulated agent can be coerced into doing harmful things — including downloading or installing...

A new prompt-injection variant called HashJack exposes a surprising and urgent risk in AI-powered browser assistants: by hiding natural‑language instructions after the “#” fragment in otherwise legitimate URLs, attackers can coerce assistants to produce malicious guidance, insert fraudulent...

Cheap doesn't have to mean compromise: 2025's best cheap desktop PCs prove that you can get sensible performance, modern connectivity, and real-world upgrade paths without breaking the bank. Background / Overview The budget desktop market in 2025 is broader and more interesting than most buyers...

Microsoft's decision to give AI agents the ability to act on a Windows 11 desktop — opening files, clicking UI elements, and chaining multi‑step workflows — is technically bold and productively promising, but it also creates fresh, concrete security and privacy challenges that Microsoft itself...

Microsoft’s own support documentation and recent reporting make one thing uncomfortably clear: Copilot Actions — the agentic feature Microsoft is previewing for Windows 11 — is powerful, experimental, and explicitly flagged by the company as a source of “novel security risks.” Background /...

Microsoft’s own documentation and multiple independent outlets now confirm a fundamental shift in Windows 11: Microsoft is moving from a suggestion-driven assistant model toward an agentic OS capable of running autonomous "agents" that can act on a user’s behalf — and the company is explicit...

Microsoft’s rollout of an experimental feature called Copilot Actions and a new agent workspace transforms Windows from a passive host for applications into an operating system that can run autonomous AI agents — and Microsoft’s own warning that these agentic features introduce “novel security...

Microsoft’s recent push of agentic features into Windows 11 — including a visible Copilot-style agent on the taskbar and a lightweight “Agent Workspace” that can read files, UI elements, and operate apps — has created a new and notable infostealer attack surface that weaponizes trusted OS-level...

Microsoft’s blunt admission that Windows 11’s new “agentic” features introduce novel security risks turns what was pitched as a productivity breakthrough into one of the most consequential security conversations for desktops in years. Background Microsoft is previewing a set of features that...

Microsoft’s push to make Windows 11 an “agentic” operating system took a visible step forward this week as Copilot and new AI agents were shown moving from background concept to taskbar-first features that users — and attackers — will watch closely. Background: the shift to an agentic Windows...

Microsoft’s new agentic AI features for Windows 11 — the capability that will let AI “click, type and scroll” on your behalf — arrive accompanied by unusually blunt, Microsoft-authored security caveats: agent accounts, isolated Agent Workspaces, admin-only toggles, and explicit warnings about...

Agentic AI browsers — the biggest breakthrough of 2025 — have lurched from promise to peril in less than a year, as independent research led by Brave has exposed systemic vulnerabilities that can turn helpful assistants into covert exfiltration channels, opening new paths for credential theft...

Microsoft and third‑party trackers have published a high‑severity advisory for CVE‑2025‑62222: a command‑injection (remote code execution) flaw in the Visual Studio Code Copilot Chat / agentic AI extension that can be triggered by attacker‑controlled prompt or repository content and, under...
