CISA warns of cyberattacks targeting fuel tank monitoring systems
US government agencies including CISA, FBI, NSA, and the Department of Energy warn that cyber threat actors are targeting internet-exposed automatic tank gauge (ATG) systems used to monitor fuel and liquid storage tanks in critical infrastructure sectors. Attackers exploit vulnerabilities such as authentication bypass, hardcoded credentials, command execution flaws, SQL injection, and privilege escalation to modify system settings. Compromise can lead to altered network configurations, tank volume data, pump controls, and disabled alerts, potentially impairing monitoring and increasing risks of leaks or equipment failures. Iranian hackers have been linked to similar attacks, though attribution remains unconfirmed. The agencies recommend blocking internet exposure, restricting remote access, replacing default passwords, using strong authentication, applying updates, and monitoring for unauthorized changes.

Technical Summary
Multiple US government agencies have issued a warning about cyberattacks targeting internet-exposed automatic tank gauge (ATG) systems that monitor fuel and liquid storage tanks across critical infrastructure sectors such as Energy, Chemical, Food and Agriculture, and Transportation. Attackers gain access through vulnerabilities including authentication bypass, hardcoded credentials, operating system command execution flaws, SQL injection, and privilege escalation. Once compromised, attackers can modify network settings, product identifiers, tank volumes, pump controls, and disable alerts, which may hinder proper monitoring and increase the risk of leaks or equipment failures. While Iranian hackers have been linked to similar incidents involving ATG systems at gas stations, definitive attribution is not confirmed. The advisory urges organizations to block ATG systems from direct internet exposure, restrict remote access via firewalls or VPNs, replace default passwords, implement multifactor authentication, apply security updates, and monitor for unauthorized changes.
Potential Impact
Successful exploitation allows attackers to alter critical monitoring parameters of fuel and liquid storage tanks, including network settings, tank volume readings, and pump controls. They can also disable alerts, potentially preventing operators from detecting leaks or equipment malfunctions. This manipulation increases the risk of undetected hazardous conditions and operational disruptions in critical infrastructure sectors. Although no physical damage has been reported, the compromise of safety-related functions poses significant operational and safety risks.
Mitigation Recommendations
The US government advisory recommends immediately blocking ATG systems from direct internet exposure. Remote access should be restricted using firewalls, VPNs, or access control lists. Default and hardcoded passwords must be replaced with strong credentials, and multifactor authentication should be implemented where possible. Organizations should apply all relevant security updates and patches to ATG systems. Continuous monitoring for unauthorized changes is advised. Since no specific patch information is provided, organizations should consult vendor advisories for updates. These mitigations are critical to reduce the risk of compromise.
