A woman walks past empty fresh-food refrigerators at an Intermarché supermarket in Névez, western France, on October 12, 2026, following a cyberattack affecting the French supermarket chains Intermarché and Cooperative U that caused their refrigerators to defrost. Some 150 to 200 Intermarché stores were targeted in the attack on October 12, 2026, along with nearly 100 Coopérative U outlets, the retailers said. BFM TV reported that rival giant E. Leclerc was also affected, with hackers "managing to remotely trigger the forced defrosting of refrigeration systems in numerous stores." (
