Bottom line: CISA and partners warn of active cyberattacks on internet-exposed tank monitoring systems in critical infrastructure.
CISA, FBI, NSA and the U.S. Department of Energy warn of targeted cyberattacks on internet-exposed automated tank gauge (ATG) systems used to monitor fuel and storage tanks in critical infrastructure.
Automated tank gauge systems are standard components for monitoring liquid levels in storage tanks. They are deployed across industries in sectors critical to national supply — such as energy, water or petrochemical industries. Many of these systems are accessible over the Internet and thus exposed to potential attackers.
U.S. security agencies document active attack campaigns targeting such systems. Successful access would enable attackers to manipulate tank levels, falsify operational data or influence control systems — with significant risks to operational continuity and physical safety.
CISOs in affected industries should verify whether ATG systems exist in their networks, particularly those with Internet connectivity. Segmented network architecture, access controls and regular patching reduce exposure risk. The warning underscores that specialized industrial control systems are also targets for attackers and must be integrated into regular cybersecurity strategy.
