PARIS, Nov 10 — France yesterday said Iran’s Revolutionary Guards were behind cyberattacks on supermarket fridges in the country last month, vowing sanctions on a European level against Tehran over the first such large-scale cyber sabotage on French territory.

Numerous French supermarkets were hit in the October 11 and 12 cyberattacks, which raised the temperatures in their refrigerators, in some cases forcing them to throw away entire inventories of perishable food.

“I can confirm that this attack was carried out by the Islamic Revolutionary Guard Corps (IRGC) of the Islamic Republic of Iran,” Foreign Minister Jean-Noel Barrot said of the cyberattacks.

“This attack is unprecedented in both its scale and its level of aggression,” he said on the sidelines of the G7 foreign ministers’ meeting in Paris.
