France: cyberattack disrupts supermarket refrigeration

E. Leclerc, Intermarche and Cooperative U confirmed a cyberattack affecting refrigeration systems in hundreds of French stores. Cooperative U reported disruption since Sunday night, 11 October 2026. Fresh and frozen food was discarded. AFP reports a Paris prosecutor investigation and affected legacy Danfoss regulators. The investigation must clarify the full damage and any link to reported fires. The attacker, motive and any Russian link are not established. This is one shared attack, not a separate incident for each retailer.
