France Launches Investigation into Iranian Cyberattacks on Supermarket Refrigeration Systems

In October 2026, a significant cyberattack targeted refrigeration systems across more than 700 supermarket locations in France, including prominent chains such as Carrefour, Monoprix, Intermarché, and Coopérative U. The attackers manipulated the defrost systems to raise temperatures within refrigerated units, potentially causing spoilage and operational disruptions.

French authorities have identified the Iranian Revolutionary Guard Corps as responsible for these attacks. French Foreign Minister Jean-Noël Barrot publicly accused this group following a G7 ministerial meeting held in Paris on November 9, 2026. Barrot confirmed that an official investigation is underway, and Iran's ambassador to France will be summoned to the Quai d'Orsay to address the issue.

The cyberattacks occurred during the night of October 11-12, 2026, targeting refrigeration controllers and tampering with temperature settings in supermarkets. The precise intention appears to have been to cause material damage and disrupt retail operations. This incident has raised concerns about the vulnerability of critical infrastructure in the retail sector to cyber threats.

Justice authorities have opened a formal inquiry focusing on the Iranian group implicated. In response to the attacks, Minister Barrot has called for sanctions at the European level to deter future incidents and strengthen cybersecurity measures across the continent.

This unprecedented case highlights the increasing risks posed by state-linked cyber actors in targeting civilian infrastructure. French officials are now prioritizing diplomatic and legal actions to hold perpetrators accountable and protect vital consumer supply chains from similar intrusions in the future.
