Threat actors are taking advantage of Internet-exposed tank gauges by breaching gas stations, opening the door to disruption.
June 5, 2026
Cyberattackers are targeting Internet-exposed automatic tank gauge (ATG) systems in the United States, and the feds are urging site owners to take swift action.
ATGs are the electronic gauges that industrial sites use to monitor liquid storage tanks, whether they contain dangerous chemicals, fuel, or whatever else. Compared to some more elaborate machinery, they're rather straightforward things: probes that feed displays, which feed data to broader supervisory control and data acquisition (SCADA) systems so that plant operators can monitor their readings at a distance. Perhaps most folks give them little thought, especially in a cybersecurity context, but they're arguably as grave of a potential risk as any other equipment at any industrial facility anywhere.
This week, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), National Security Agency (NSA), Department of Energy (DoE), Environmental Protection Agency (EPA), Transportation Security Administration (TSA), Department of Transportation (DOT), and US Department of Agriculture (USDA) published a joint notice urging industrial organizations to harden their ATGs from cyberattack.
