Iranian security experts have thwarted an industrial espionage attempt on Islamic Republic's oil ministry, cyber police chief announced, claiming the attack originated in the US.

Speaking at a cyber crime forum in Tehran on Tuesday, the head of Iran's Cyber Police (FATA) Brigadier General Seyed Kamal Hadianfar announced that Cyber Attacks Emergency Center had defended the oil ministry against hackers. The alleged attack took place during a four-day holiday on March 21-24.

Hadianfar said, as cited by FARS news agency.

The chief of cyber police said that Tehran had already informed Washington via an official letter and issued an as FATA passed the issue to the foreign ministry.

FATA discovers, identifies and solves some 90 percent of Internet crimes committed against Iran, Iran's Interior Minister Abdolreza Rahmani Fazli said speaking at the same event. the minister added.

The cyber standoff between Iran and the US has been widely reported over recent years. Both US and Tehran have accused each other of cybercrimes aimed at strategic sectors of the government and the economy.

In February 2015, US Director of National Intelligence James Clapper named Iran among the leading cyber threats to the United States. In the same month the Islamic Republic revealed that several cyber attacks on Iran's scientific and industrial infrastructures had been thwarted.

Senior Military Aide to the Supreme Leader Major General Yahya Rahim Safavi was quoted at the time as saying.

One of the most well-known attacks on Iranian state infrastructure was carried out in 2010. A sophisticated malware called Stuxnet, apparently designed by a state actor, was used to infect equipment at Natanz nuclear facilities. The destructive computer worm compromised centrifuges, crippling Iran's nuclear enrichment capabilities. Tehran blamed the attack on the US, with Edward Snowden later confirming the tool was likely created by the NSA and co-written by Israel.

For its part the US State Department earlier this month refereed to Iran as a Iran is "rapidly building cyber warfare capabilities" and may be planning a cyber attack on critical infrastructure, a State Department security report warned.
