Background for this topic.
Exposure is the condition in which a system, service, credential, vulnerability, or sensitive information is accessible or discoverable by people or systems that should not reach it. In threat modeling, it describes an attack surface or loss of control—not proof that an attacker has succeeded. Examples include an internet-facing administration interface, cloud storage with unintended permissions, a secret committed to source code, or personal data sent to an unintended recipient. Its significance depends on what is exposed, who can reach it, and which protections remain.
The primary defense is exposure reduction: maintain an accurate asset inventory, remove unnecessary public access, enforce least-privilege permissions and strong authentication, patch externally reachable software, and revoke leaked credentials or secrets. Encryption can limit the value of exposed data, but does not correct an exposed access path. Continuous scanning and log review help identify changes and support rapid containment when exposure is discovered.
Threat actors are taking advantage of Internet-exposed tank gauges by breaching gas stations, opening the door to disruption.
Over 900 automatic tank gauge (ATG) systems across the United States, used to monitor fuel and chemical storage tanks across various critical infrastructure sectors, have been found exposed online and are vulnerable to ongoing attacks. [...]
CISA, the FBI, the NSA, the Department of Energy, and other US government partners are warning that hackers are targeting internet-exposed automatic tank gauge (ATG) systems used to monitor fuel and liquid storage tanks across various critical infrastructure sectors. [...]
