Several fuel storage monitoring systems in the United States have been breached by suspected Iranian hackers, according to a report citing multiple sources. The attackers accessed automatic tank gauge systems that were online and not password protected, allowing them to alter display readings, though they could not change actual fuel levels. No physical damage or injuries were reported.

Experts warned that access to such systems could allow hackers to interfere with leak detection, posing potential safety risks. Iran is considered a prime suspect due to its history of targeting similar systems, though investigators said there was limited evidence to conclusively attribute the breaches.

Cybersecurity researchers and federal officials have repeatedly urged infrastructure operators to better secure their networks. Iranian-linked groups have previously targeted oil, gas, and water systems, and have carried out additional cyber operations against government and military personnel in both the United States and Israel, sometimes exaggerating the extent of their intrusions.
