France opens probe into Iranian cyber unit over fridge attacks

France on Monday said Iran's Revolutionary Guards were behind "unprecedented" cyberattacks on supermarket fridges in the country last month, vowing sanctions on a European level against Tehran. Swathes of 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.
