CISA warns of cyberattacks targeting fuel tank monitoring systems

Source Bleeping Computer

Description

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. [...]

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.

Defensive guidance

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. These mitigations are critical to reduce the risk of compromise.
