Overview
- Stores in Belgium, Luxembourg, Sweden and several other European countries recorded sudden refrigeration failures during the night of Monday to Tuesday, Nov. 1–2, forcing staff to discard spoiled food as temperatures in some units rose into the tens of degrees Celsius.
- Major retailers including Ahold Delhaize, Carrefour, Intermarché, Colruyt, ICA, Coop and Ikea reported incidents and opened investigations, with some calling the events 'incidents informatiques' or cyberattacks and others saying they have no definitive evidence yet.
- Authorities and reporting note strong similarities to the Oct. 12 attack in France, where France’s ANSSI said attackers exploited basic security lapses in Danfoss-supplied refrigeration control units that lacked updates or secure installation.
- The scale of losses varies by country with Belgian retailers saying the impact was limited and most stores opened, while Swedish outlets reported more food waste; total financial and food‑safety costs remain unknown.
- National cyber centres have issued alerts to merchants and investigators are focused on whether the same technical vulnerability or actor is responsible, what patches are needed, and how vendors and installers will be held to account to stop repeat disruptions.
