US investigates possible Iranian cyberattacks on fuel storage systems

US officials are investigating suspected cyber intrusions targeting fuel monitoring systems at gas stations across multiple states, with early assessments suggesting possible Iranian involvement, according to CNN sources briefed on the matter.

The breaches are believed to have exploited vulnerabilities in automatic tank gauge (ATG) systems that were left exposed online without password protection. In some cases, hackers were able to manipulate display readings showing fuel levels in storage tanks, though officials say there is no evidence that actual fuel quantities were affected.

While the intrusions have not resulted in physical damage or injuries, cybersecurity experts and US officials have raised concerns that access to such systems could, in theory, allow attackers to mask fuel leaks or create hazardous conditions undetected.

Investigators have not publicly attributed the activity, but sources said Iran is considered a leading suspect due to its previous cyber operations targeting critical infrastructure. However, officials cautioned that definitive attribution may not be possible because of limited forensic evidence left behind by the attackers.

If confirmed, the activity would mark another instance of alleged Iranian cyber operations aimed at US critical infrastructure, amid heightened tensions between Iran, the United States, and Israel.

The reported breaches also come amid broader economic and political sensitivity in the US, where energy costs remain a concern. A recent CNN poll indicated that 75% of US adults believe the ongoing conflict involving Iran has negatively affected their personal finances.
