Today’s threat landscape highlights increasing risks to operational technology and industrial control systems across critical infrastructure sectors. Attackers continue to exploit exposed devices and vulnerabilities, emphasizing the urgent need for proactive visibility and defense in OT, ICS, and IoT environments.
CISA and Federal Partners Warn of 900+ Exposed Automatic Tank Gauge Systems at US Gas Stations
CISA, FBI, NSA, and the Department of Energy issued a joint advisory revealing that over 900 automatic tank gauge systems at US gas stations and critical infrastructure are internet-exposed and actively targeted. Attackers exploit hardcoded credentials, authentication bypasses, and command injection flaws to alter system settings, disable alerts, and increase risks of fuel leaks or equipment failures. The advisory follows reports linking Iranian threat actors to compromises manipulating fuel display readings.

Cisco Catalyst SD-WAN Manager Hit by Unpatched Root-Level Command Injection Flaw CVE-2026-20245
Cisco disclosed CVE-2026-20245, a privilege escalation vulnerability in Catalyst SD-WAN Manager allowing authenticated users with netadmin rights to execute root commands via crafted file uploads. With no patch or workaround currently available, limited exploitation cases have resulted in unauthorized configuration changes on edge devices. OT operators using SD-WAN to connect industrial sites should audit logs and run diagnostic commands to detect compromises before applying future patches.
