How Attackers Abuse Microsoft Teams and Quick Assist: Inside the Helpdesk Impersonation Playbook

A new wave of attacks is quietly abusing everyday collaboration tools to bypass user suspicion and gain hands-on control of corporate endpoints.

Anthropic’s Mythos and the New Era of AI-Accelerated Cyber Risk

Anthropic’s new Mythos model has crystallized a fear many in security have quietly harbored: advanced, cyber-focused AI can find software flaws faster than people and, in some cases, generate the exact exploits to weaponize them. That capability promises major defensive benefits—accelerating the discovery and remediation of long-hidden vulnerabilities—but it also hands would-be attackers automated, scalable tools that could outpace the ability of organizations to patch and contain damage. Why Mythos…

One-Click RCE in Azure Windows Admin Center: what happened and what you need to do

Windows Admin Center (WAC) is a convenient, browser-based management hub for administrators to manage servers, clients, and clusters from a centralized interface. A recent Cymulate Research Labs disclosure describes a critical chain of flaws that let an attacker achieve unauthenticated, one-click remote code execution (RCE) against both Azure-integrated and on-premises WAC deployments. The exploit requires little user interaction—a maliciously crafted link—and, if successful, can silently execute arbitrary commands and take…
