A major cyberattack targeting commercial refrigeration systems across France has left more than 150 supermarkets facing millions of euros in damages after hackers remotely altered fridge temperatures overnight.
The attack compromised cold-chain control software across nationwide locations of Intermarché, E.Leclerc, and Coopérative U (Super U).
Rather than shutting systems off, the attackers remotely reprogrammed cooling regulators to force a continuous defrost cycle, driving internal temperatures up to 50ºC.
Store workers arriving on Monday morning discovered compromised units left vast quantities of fresh produce, meat, dairy, and frozen goods completely spoiled.
