Microsoft’s High Performance Compute (HPC) Pack is under scrutiny after a reported deserialization vulnerability that — if the technical description is accurate — would allow an attacker to execute arbitrary code over a networked HPC cluster; however, the specific identifier CVE-2025-55232 could...

Microsoft’s Security Response Center lists CVE-2025-54095 as an out-of-bounds read in the Windows Routing and Remote Access Service (RRAS) that can disclose memory contents to a remote attacker over the network. Background / Overview Routing and Remote Access Service (RRAS) is a long‑standing...

A newly republished advisory from CISA and Rockwell Automation raises urgent operational and security flags for organizations using the CompactLogix® 5480 controller family: the devices running specific Windows packages are affected by a Missing Authentication for Critical Function vulnerability...

CISA’s latest update to the Known Exploited Vulnerabilities (KEV) Catalog adds three actively exploited flaws — a Linux kernel TOCTOU race condition, an Android Runtime issue, and a high‑impact Sitecore deserialization vulnerability — forcing organizations that track KEV and federal agencies...

Schneider Electric has published an advisory—republished by CISA—about an improper privilege management vulnerability in its Saitel family of Remote Terminal Units (RTUs) that has been assigned CVE‑2025‑8453 and carries a CVSS v3.1 base score of 6.7, affecting Saitel DR RTU firmware versions...

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...
