Iranian hackers exploited internet-exposed automatic tank gauge (ATG) systems that lacked passwords, altering fuel gauge displays.
The Cybersecurity and Infrastructure Security Agency (CISA) advised station owners to disconnect ATGs from the internet and use strong passwords.

History

Historical Context

On 23 December 2015 Russian-linked Sandworm used BlackEnergy to disrupt three Ukrainian utilities, cutting power for about 230,000 customers. The attack, followed by a similar December 2016 outage, prompted U.S. officials to prioritize overall critical grid cyber defenses. Similar concerns now arise over attacks on fuel-tank gauge systems, echoing the earlier grid-security push.
