Iranian Hackers Suspected of Accessing U.S. Gas Station Fuel Monitoring Systems

WASHINGTON — Federal authorities are investigating suspected Iranian hackers who targeted fuel monitoring and payment systems at gas stations across the United States, according to joint alerts issued this week by the FBI, Cybersecurity and Infrastructure Security Agency (CISA), and Department of Energy.

The intrusions focused on point-of-sale terminals and remote tank monitoring software used by thousands of convenience stores and fuel distributors. Officials believe the activity is linked to Iranian government-affiliated cyber actors seeking intelligence on U.S. fuel infrastructure and potential disruption capabilities amid the ongoing Middle East conflict.

No widespread fuel shortages or operational disruptions have been reported. However, the alerts warn that compromised systems could allow attackers to manipulate inventory data, alter price displays, steal customer payment information, or interfere with fuel delivery schedules in a future escalation.

The suspected campaigns involved phishing and malware designed to exploit connected devices common in modern gas stations. These systems handle real-time tank levels, automatic reordering, and credit card processing. The activity has been detected in multiple states, though exact numbers of affected locations remain undisclosed for security reasons.

This latest incident fits a pattern of Iranian cyber operations against U.S. critical infrastructure since the conflict with Iran began in late February. Previous attacks have targeted water treatment facilities, ports, and energy companies.

Industry groups have urged station owners to immediately enable multi-factor authentication, segment networks, apply software patches, and monitor for unusual login activity. The FBI and CISA are actively investigating and have asked operators to report suspicious incidents.

The alerts come as the U.S. maintains its naval blockade of Iranian ports and works to stabilize the fragile ceasefire in the Strait of Hormuz. Officials described the probes as part of broader efforts to harden domestic energy infrastructure against foreign threats. No arrests or formal attributions have been announced.
