CISA and Partners Urge Hardening Automatic Tank Gauge Systems
Summary
CISA and multiple other US government agencies are urging owners and operators of Automatic Tank Gauge (ATG) systems to implement security measures. This advisory follows observed malicious cyber activity where threat actors are compromising internet-exposed ATG systems and executing commands to modify them, potentially impacting critical infrastructure sectors.
IFF Assessment
The article highlights ongoing malicious cyber activity targeting critical infrastructure systems, presenting a clear threat to defenders.
Defender Context
Defenders should be aware of the increased risk to Automatic Tank Gauge systems, particularly those exposed to the internet. The described TTPs, including authentication bypass and command execution, necessitate vigilance and proactive security hardening, such as implementing strong passwords and segmenting these systems from public networks.
