A coordinated cyberattack hit refrigeration systems at French grocery chains E. Leclerc, Intermarché and Coopérative U early Monday, forcing connected fridges and freezers into defrost mode for hours and raising temperatures to around 50°C. The intrusion spoiled food and triggered fires in some stores, and authorities say other chains were also affected. Danfoss, maker of the targeted AK-SM800 and AK-SC355 system controllers, said the hit units were running outdated firmware and that it is working with customers on mitigation.

A cyberattack has reportedly hit Danfoss-made refrigeration controls used by Intermarché, Leclerc and Coopérative U stores in France, forcing fridges and freezers into continuous defrost cycles at around 50°C instead of their normal two-hour daily cycle. Coopérative U president Dominique Schelcher confirmed the attack began overnight Monday, called it 'extremely serious,' and said teams were working to restore systems while an investigation is launched. Electronic shelf pricing and deliveries have also reportedly been disrupted.

Hackers remotely triggered defrost mode on Danfoss-managed refrigeration systems at roughly 150 Intermarché stores Sunday night, raising cooler temperatures to 50°C and spoiling food before staff noticed six hours later. Fewer than 100 Cooperative U stores and some Leclerc locations were also affected, with electronic pricing labels reportedly disrupted too. Early estimates put losses at around 300,000 euros, a figure that could rise as investigations continue.
