Hackers disrupt supermarket refrigeration in seven European countries, raising temperatures

Situation Overview

On 2 November 2026, reports said a suspected cyberattack manipulated supermarket refrigeration systems in multiple European countries, raising fridge and freezer temperatures to around 50°C and triggering defrost mode. The incident affected supermarkets in Belgium, Sweden, Luxembourg, the Netherlands, Ireland, Finland and France, with retailers including Delhaize, Carrefour, Coop and SuperValu reporting losses of goods and resorting to refrigerated trucks or removing products from sale. The European Commission’s agriculture commissioner said the attack was a deliberate attempt to disrupt food supply in the European Union. The reports described the method as similar to an attack in France in October, and said investigations were ongoing with the attackers’ identity and motives still unclear. The next concrete step reported is the continuation of investigations into the perpetrators and the scope of the disruption.

Geopolitical Implications

1. 01

   The targeting of supermarket refrigeration systems highlights the vulnerability of food-supply infrastructure to cyber operations across EU member states.
