Iran's Oil Minister Javad Owji on Monday confirmed that a nationwide disruption to petrol stations was caused by a cyberattack, Paralel.Az reports citing Reuters.

A hacking group that Iran accuses of having links to Israel claimed it carried out the attack which disrupted services at petrol stations across the country on Monday, Iranian state TV and Israeli local media reported.

Owji had earlier told Iranian state TV that services had been disrupted at about 70% of Iran's petrol stations and that outside interference was a possible cause. He later said 1,650 petrol stations were operational. The ministry supervises 3,800 petrol stations.

Iran's state TV news said a group called Gonjeshke Darande or "Predatory Sparrow" had claimed it was behind the disruption. Israeli local media outlets also reported the claim. "This cyberattack was carried out in a controlled manner to avoid potential damage to emergency services," the group said in a statement on Telegram. The digital strike was "in response to the aggression of the Islamic Republic and its proxies in the region", it added.

Asked about the cyber attacks, Israeli government spokesperson Tal Heinrich told a press briefing on Monday: "We have nothing to say about Iran's claims."

Iran's civil defence agency, which is responsible for cybersecurity, said it was still considering all possible causes for the disruptions as it investigated.

Iranian state media added that the hacker group had in the past claimed cyberattacks against Iranian petrol stations, rail networks and steel factories.

Israel's Cyber Unit on Monday said Iran and Hezbollah were behind an attempted cyberattack on a hospital in northern Israel about three weeks ago. It said the attack was thwarted but hackers were able to retrieve "some of the sensitive information stored in the hospital's information systems".
