Europe's supermarkets hit: fridges forced into defrost in France, Ahold Delhaize takes systems offline
A rare cyberattack with physical, perishable consequences, and the retailer statements that followed.
An attack on Danfoss-made refrigeration controls at French supermarkets including Intermarché, Leclerc and Coopérative U set units into a continuous defrost cycle at 50°C overnight, Tom's Hardware reports, citing La Dépêche; early losses were put near €300,000. Coopérative U's president called it "extremely serious."
The same weekend Dutch retailer Ahold Delhaize (Albert Heijn, Etos, Gall & Gall) took several systems offline over a "security issue". On Tuesday it said it had no indication that customer data was stolen, and the Dutch National Cyber Security Centre said there was no reason to believe the Dutch incident was linked to those in other countries.
