French Supermarkets Hit by Cyber Heat Attack

Hackers raised temperatures in hundreds of French supermarkets overnight, causing fires and massive food spoilage. The attack, which reached as high as one hundred twenty‑two degrees Fahrenheit, forced retailers to discard thousands of items to avoid health risks. Carrefour reported eighty of its stores affected, while Intermarche’s owner, Les Mousquetaires, said about one hundred fifty outlets saw fridges heated to fifty degrees Celsius for six hours. French authorities, led by Prime Minister Sebastien Lecornu, directed the National Cybersecurity Agency to investigate. ANSSI identified a vulnerability in software supplied by Danish firm Danfoss, whose outdated firmware had been exploited. The incident has already cost retailers tens of millions of euros and prompted a broader European cybersecurity review. The attack underscores the fragility of connected supply chains and the urgent need for updated firmware and robust monitoring.
