Cybercriminals are actively exploiting a critical Windows Server Update Services vulnerability that bypasses Microsoft's earlier patch from this month. The tech giant released an emergency fix Thursday for CVE-2025-59287, but researchers detected live attacks by Friday. Over 2,800 vulnerable servers remain exposed online, with 28% located in the United States. Security firm Huntress has tracked five active attacks so far. The flaw affects software dating back to 2012 and allows attackers to gain complete system control without authentication. The risk extends beyond individual servers—attackers could potentially push malware to entire networks disguised as legitimate Microsoft updates, turning trusted update systems into distribution weapons. **Source:** [CyberScoop](https://cyberscoop.com/microsoft-windows-server-update-services-vulnerability-exploited-attacks/)
