Microsoft has made the Model Context Protocol (MCP) a first‑class citizen in Visual Studio, shipping general availability support that lets Copilot Chat and other agentic features connect to local or remote MCP servers via a simple .mcp.json configuration — a major convenience for developers...

Windows 11 ships with a far stronger security baseline than its predecessors, but real-world attackers and configuration gaps still find workarounds—meaning Defender and Windows Security are necessary, not sufficient, for modern threat defense. Background Windows 11’s built-in...

Siemens’ RUGGEDCOM APE1808 appliances carry high‑risk management‑plane vulnerabilities that can let an authenticated administrator—or an attacker who gains elevated credentials—execute arbitrary operating‑system commands and escalate local service privileges, creating a significant threat to...

Zenity Labs’ Black Hat presentation unveiled a dramatic new class of threats to enterprise AI: “zero‑click” hijacking techniques that can silently compromise widely used agents and assistants — from ChatGPT to Microsoft Copilot, Salesforce Einstein, and Google Gemini — allowing attackers to...

Microsoft’s security advisory confirms a new Kerberos vulnerability — CVE-2025-53779 — described as a relative path traversal flaw in Windows Kerberos that can be abused by an authorized attacker over a network to elevate privileges, and organizations that rely on Kerberos-based authentication...
