The Iranian Oil Ministry, the National Iranian Oil Company, and a number of other companies affiliated with the ministry, were targeted by a computer worm on Sunday, but the malware was detected before it could infect the systems, the Mehr News Agency has learnt.
The cyber attack disrupted Internet access at the aforementioned organizations and companies, and the relevant officials are investigating the issue.
However, the Oil Ministry has not yet confirmed the report.
In addition, an unidentified Oil Ministry official told the Mehr on Sunday that the cyber attack had caused no damage.
But the Kharg Island oil terminal, the ministry headquarters, and other facilities were all taken offline, the agency quoted Hamdollah Mohammadnejad, deputy oil minister in charge of civil defense, as saying. Some 80 percent of Iran's daily 2.2 million barrels of crude export goes through the Kharg facility, located off its southern coast.
