Critical Cyber Alerts: StoneFly Storage Concentrator and XZ Utils Vulnerabilities Detected in Denver

Two Severity-10 cyber alerts have been triggered in Denver flagging critical vulnerabilities in StoneFly Storage Concentrator and XZ Utils (impacting Backup & Recovery products). Denver carries a very high-density operations footprint — over 360,000 combined contact-center, back-office, and knowledge-worker seats — making exploitation of storage or backup infrastructure potentially disruptive to data availability, backup integrity, and service continuity. Operations and IT security leaders should validate patching status, confirm backup system integrity, and assess exposure across Denver-based sites.
