Iran has detected and removed malicious software from two of its petrochemical complexes, a senior military official said on Saturday, after announcing last week it was investigating whether recent petrochemical fires were caused by cybertattacks.
The official said the malware at the two plants was inactive and had not played a role in the fires.
“In periodical inspection of petrochemical units, a type of industrial malware was detected and the necessary defensive measures were taken,” Gholamreza Jalali, head of Iran’s civilian defense, was quoted as saying by the state news agency IRNA.
Iran is alert to the threat of cybertattack by foreign countries. The US and Israel covertly sabotaged Iran’s nuclear program in 2009 and 2010 with the now-famous Stuxnet computer virus, which destroyed Iranian centrifuges.
