Daily Cyber News: Exploited Zyxel switches expose nearly 1,000 systems worldwide

Organizations using Zyxel GS1900 switches face confirmed exploitation across 996 devices in 48 countries. CISA added C V E dash 2026 dash 7273 to its Known Exploited Vulnerabilities catalog on September 21st, making this a clear patching priority. Researchers linked the activity to a Chinese-speaking actor that has targeted Zyxel, WordPress, and Ubiquiti systems since at least June.

Key context: This matters because compromised edge devices can provide access while looking like ordinary network infrastructure.

Additional detail: Patch affected Zyxel switches immediately, then investigate account, configuration, and traffic changes that may have happened before remediation.
