Hackers activate automatic defrosting in supermarket fridges across Europe
Attackers hijacked Danfoss refrigeration controllers at French chains including Intermarché, Leclerc and Coopérative U, forcing fridges and freezers into a continuous 50°C defrost cycle; early losses are near €300,000. Separately, Dutch grocers Albert Heijn, Etos and Gall & Gall shut down systems after an incident that scrambled electronic shelf prices.
