France has condemned Iran for the recent cyberattack that struck refrigeration systems in supermarkets across France. An investigation by French cybersecurity authorities, including the Cyber Crisis Coordination Centre (C4) and the National Cybersecurity Agency of France (ANSSI), has also identified the Iranian units responsible for the attack.
France has said that it will propose new European Union sanctions against Iran and those responsible for the attack, and has stated that it reserves the right to take further action.
The French investigation has attributed the attack to the Shahid Kaveh cyber unit, which operates within the Electronic and Cyber Center of Iran’s Islamic Revolutionary Guard Corps (IRGC).
During the night of 11 to 12 October 2026, refrigeration systems at approximately 700 retail sites across France were targeted. The attackers remotely changed the defrosting settings of industrial refrigeration equipment, raising temperatures and causing substantial losses of food products. The attacks also caused at least 15 fires. Several major supermarket chains were affected, including Casino, Leclerc, Coopérative U, Metro, Carrefour and Intermarché.
On the night of 1 to 2 November, another cyberattack also targeted refrigeration monitoring and control systems at three regional facilities of the French Blood Establishment (Établissement français du sang – EFS). However, the attack was quickly contained after staff received alerts and transferred blood products to refrigerators that were not connected to the compromised systems. No blood supplies were affected.
France is currently supporting Saudi Arabia with air defences against Houthi strikes. It also helped Saudi Arabia and other Gulf countries with air defences when Iran bombed these countries with drones and ballistic missiles.
