Hundreds of French supermarkets experienced a significant cyberattack that disabled their refrigeration systems, resulting in the loss of fresh and frozen food estimated to be worth millions of euros. Hackers compromised software that retailers rely on to monitor and control temperatures in cold storage units remotely. Refrigeration units malfunctioned overnight, with some reaching temperatures as high as 50 degrees Celsius, causing extensive spoilage of perishable goods.
The supermarket chain Coopérative U reported that more than 100 of its stores were targeted. The company's chief executive described the incident as "extremely serious and unprecedented." Intermarché and its subsidiary Netto brand experienced disruptions across 180 stores, while approximately 100 additional shops were immediately disconnected from the internet as a precautionary measure. Other major retailers, including Carrefour, Monoprix and E.Leclerc, were also affected by the attack.
The cyberattack focused on software provided by Danfoss, a Danish engineering company whose systems are widely used by supermarkets to manage remote cold storage operations. The identity of those responsible remains unknown, as no group has claimed responsibility for the attack. The financial impact of destroyed inventory is still being calculated across all the affected retail chains.
