Security researchers say a new wave of prompt‑injection techniques can coerce mainstream AI assistants — including Microsoft Copilot and xAI’s Grok — into behaving as covert command‑and‑control (C2) relays, exfiltrating data or executing attacker‑supplied workflows after a single crafted input...

Microsoft’s recent changes have finally untangled one of Windows 11’s most persistent irritations: setting a third‑party browser as the operating system’s default is now far less painful than it was at launch, and regulatory pressure in Europe has pushed the company even further toward...

Microsoft’s Defender researchers have pulled back the curtain on a quiet but powerful marketing vector: seemingly harmless “Summarize with AI” and “Share with AI” buttons that surreptitiously instruct chat assistants to remember particular companies or sites, creating persistent, invisible...

Microsoft’s security team is warning that a new, low-cost marketing tactic is quietly weaponizing AI convenience: companies are embedding hidden instructions in “Summarize with AI” and share-with-AI buttons to inject persistent recommendations into assistants’ memories — a technique the...

Linux still beats Windows 11 in a handful of quietly significant ways — not because it has prettier UI animations or a bigger marketing budget, but because of fundamentals: cost, hardware fit, user control, the absence of baked‑in AI agents, and a privacy model that treats telemetry as optional...

Microsoft's public promise to "fix Windows 11" this year is not a marketing flourish — it's a direct response to hard, visible pain across the platform, and the company is now mobilizing a formal "swarming" effort to address the problems users and testers have been raising. Pavan Davuluri, who...

Security researchers have shown that a single, seemingly legitimate Copilot link could be turned into a stealthy data‑exfiltration pipeline — a one‑click attack dubbed Reprompt — and Microsoft moved to mitigate the specific vector during the January 2026 Patch Tuesday updates. ) Background...

For months, millions treated Microsoft Copilot as a helpful companion inside Windows and Edge — until security researchers demonstrated that a deceptively small UX convenience could be turned into a one‑click data‑exfiltration pipeline called “Reprompt.” Background / overview Varonis Threat Labs...

Windows 11’s Night light gives you a one-click way to cut blue light, warm your display, and reduce evening eye strain — here’s a practical, forensic guide to turning it on, tuning it, troubleshooting when it’s missing, and choosing safer alternatives when you need color accuracy or more...

A deceptively small convenience — a Copilot deep link that pre-fills your assistant’s prompt — has been weaponized into a one-click data-exfiltration technique researchers call Reprompt, demonstrating how AI assistants with access and memory can become a silent conduit for sensitive information...

A single, deceptively small UX convenience in Microsoft’s Copilot ecosystem was chained into a practical, one‑click information‑disclosurere exploit that could siphon profile attributes, file summaries and chat memory from authenticated Copilot Personal sessions — a vulnerabilidentity tracked as...

A high‑impact information‑disclosure flaw in Microsoft’s Copilot family of assistants — widely discussed under the researcher name “Reprompt” and tracked by some vendors as CVE‑2026‑24307 — exposed a design weak‑spot in how Copilot handled prompt content embedded in links, enabling a...
