Customers enter an Intermarche supermarket in Issy-les-Moulineaux, on the outskirts of Paris, on October 12, 2026, , following a cyberattack affecting the French supermarket chains Intermarche 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." (Photo by Dimitar DILKOFF / AFP via Getty Images)
