Cybercriminals are probing a quiet layer of fuel infrastructure: the systems that monitor what is inside storage tanks. According to a new government advisory, reports have emerged of threat actors targeting Automatic Tank Gauge (ATG) systems used to monitor fuel and liquid storage tanks across the US. Officials say these actors have already compromised internet-facing devices in recent months, raising concerns about the security of these often-overlooked industrial systems. The warning points to a growing trend across the threat landscape. Instead of focusing exclusively on digital data theft or enterprise networks, attackers are also probing technologies closer to physical operations, where disruptions can halt real-world operations, affecting millions. What does an ATG system do, and why are they being targeted? At their core, ATG systems serve as digital monitoring platforms for checking inventory, detecting leaks, and managing tank conditions across sites ranging from gas stations to industrial facilities. Because of the role they play in keeping everyday activities that rely on them running smoothly, they’ve recently become active targets for cyberattacks aimed at disrupting these …
