Europe's Supermarkets Hit by Cyberattacks Targeting Refrigeration

Supermarkets in Sweden, Belgium, Luxembourg, and Estonia have reported issues with their refrigeration systems, with temperatures altered without authorization. The incidents occurred across multiple locations, affecting both large chains and individual stores.

In Sweden, ICA supermarkets in Sjöbo, Tomelilla, and Stockholm reported refrigeration system breaches, with temperatures raised to 50 degrees Celsius, rendering stored food unsafe. The company confirmed that a limited number of stores experienced the issue overnight.

Ahold Delhaize, a Dutch supermarket group, confirmed that cooling systems in Belgium and Luxembourg were affected, with unauthorized temperature changes detected overnight. The company is currently investigating the incident, which impacted several dozen stores, mostly in Belgium.

Carrefour Belgium also reported a cyberattack targeting refrigeration equipment, with 15 of its over 700 stores affected. In Estonia, Selver confirmed that one of its stores was impacted, with temperatures raised to 50 degrees Celsius by attackers accessing the refrigeration control system.

The attacks follow a similar pattern to a wave of refrigeration system breaches in France earlier this year, which involved thermostats manufactured by Danfoss. However, there is no confirmation that Danfoss equipment was involved in the latest attacks across Europe.

The affected companies are currently investigating the incidents, but no individual, hacking group, or organization has claimed responsibility for the attacks.
