French Foreign Minister Jean-Noël Barrot has accused Iran's Islamic Revolutionary Guard Corps of directing cyberattacks against supermarket refrigeration systems on the night of October 11 and 12. The operation transformed routine commercial equipment into a distributed target with consequences for food, safety and public confidence.
Attackers manually overrode temperatures in units across more than 700 retail locations. Carrefour, Monoprix, Intermarché and Coopérative U were among the affected chains, showing how a common technology platform can create national exposure across otherwise separate companies.
France says the intrusions caused substantial material damage, including fires, while spoiled food and other losses reached tens of millions of euros. The attack demonstrates that cyber operations against civilian infrastructure do not need to interrupt electricity or banking to impose broad economic costs.
Barrot said the investigation remained open and announced that Iran's ambassador would be summoned. Paris also intends to pursue sanctions at European level, which will require attribution evidence strong enough to support collective action rather than relying on a public accusation alone.
EU foreign-policy chief Kaja Kallas said the November 16 Foreign Affairs Council would examine cyberattacks across Europe and that an attributed attack should draw a stronger response. Her position links the French case to a wider deterrence problem involving multiple forms of hybrid pressure.
French authorities cited earlier hostile acts attributed to Iran, including a 2023 attack on Charlie Hebdo and activity around the 2024 Olympic Games. That history supports Paris's claim of a pattern, though each incident still requires its own technical and legal investigation.
Barrot's challenge is to convert attribution into proportionate defence. France and the EU need sanctions, evidence-sharing and minimum security standards for connected industrial equipment, because the next target could be any civilian system where remote control creates physical consequences.
