Zyxel Issues Warning on Faulty Firewall Update

🔄 Zyxel issues warning over faulty security update causing firewall malfunctions. The company has alerted users of its USG FLEX and ATP Series firewalls about critical issues stemming from a recent Application Signature Update, which has led to reboot loops, login access problems, and high CPU usage. The update, pushed out between January 24 and 25, is not linked to any known security vulnerabilities but has affected devices with active security licenses. Affected users must physically access their devices and follow a detailed recovery process involving console connections and firmware updates to resolve the issues. Zyxel is offering support through a Microsoft Teams session for further assistance.
