More than 80 percent of Iran's gas stations have returned to service, a spokesperson for the National Iranian Oil Products Distribution Company says, after a massive cyberattack disrupted the sale of subsidized gasoline.

"The number of stations connected to the smart fueling system has been increasing … and we hope the system will be fully operational by the end of today," Fatemeh Kahi said.

The attack on Tuesday disrupted the sale of heavily subsidized gasoline in Iran, causing long queues at gas stations across the country.

Secretary of Iran's Supreme Council of Cyberspace said the massive cyberattack on refueling systems in Tehran and other cities has been contained and all gas stations are returning to normal.

"The disruption in the systems of 4,300 gas stations in the country was caused by a widespread cyberattack that has now been contained and we hope that all fuel stations will return to normal by tomorrow," Abolhasan Firouzabadi told national broadcaster IRIB late Tuesday.

Officials at the ministry of petroleum said the cyberattack disrupted only sales with smart cards used for cheaper rationed gasoline, and clients could still buy fuel at higher rates. However, the scale of the aggression suggested it was not the work of an individual or a small group.

"The attacks were so widespread that all 4,300 gas stations in the country were disrupted," Firouzabadi said.

In the past, the United States and Israel have been implicated beyond doubt in a series of cyber terrorism against the Islamic Republic.

The two regimes are widely believed to have developed Stuxnet discovered in 2010 after it was used to attack a uranium enrichment facility in Iran in the first publicly known example of cyber terrorism by using a computer virus to attack industrial machinery.

Firouzabadi said the results of an investigation into the origin of the attack on Iran's refueling systems will be announced in the next 7-10 days.

"It is possible that this attack, like the cyberattack on the railway systems of the Islamic Republic of Iran, was carried out from abroad," he said.

"Although this cyberattack has been contained now, it has caused a lot of problems and we hope that all fuel stations will return to normal tomorrow."
