U.S. officials believe suspected Iranian hackers broke into fuel-tank monitoring systems at gas stations in several states. The attackers targeted automatic tank gauges, or ATG systems, that were exposed online without passwords and changed displayed readings but reportedly could not alter actual fuel volumes. No physical damage has been reported, but officials warned the access could potentially hide leaks or create other safety and critical-infrastructure risks.
Why it matters: Gas stations and operators using older internet-connected monitoring gear may be at risk right now, especially if devices are reachable online without authentication. Operators should immediately remove ATG systems from direct internet exposure, require passwords, and review logs and display anomalies.

It ties the broader multi-agency U.S. warning on exposed Automatic Tank Gauge systems to the previously reported Iran-linked compromises of gas-station tank monitors and reiterates the immediate mitigation guidance to disconnect exposed systems from the internet.

This is a direct government follow-up to the same tank-monitoring intrusion activity previously reported by CNN, adding an official multi-agency advisory, broader sector impact beyond gas stations, and specific attack methods and mitigations. It also notes the activity remains unattributed in the advisory despite earlier reporting pointing to suspected Iranian involvement.
