Cyberattack on freezer systems hits supermarkets in seven European countries

· Cybersecurity · European Union

Supermarket chains in at least seven European countries said the temperatures of refrigerators and freezers in some stores rose overnight, in a suspected cyberattack. Chains in Belgium, Estonia, Finland, Ireland, Luxembourg, the Netherlands and Sweden were affected, with thermostats in some cases remotely cranked up to as high as 50C. Shops dumped large quantities of spoiled food. The EU denounced the incident as a deliberate attempt to disrupt the bloc's food supply chain. It follows a similar hack of French shops, highlighting the risks of connecting industrial refrigeration systems to the internet. It remains unclear who was responsible.

Why it matters：The attack shows how exposed connected industrial equipment is, and a coordinated hit on food retail across borders raises supply-chain and food-safety concerns.

Key points

  • Freezer temperatures reportedly rose to as high as 50C in some shops.
  • Affected countries include Belgium, Estonia, Finland, Ireland, Luxembourg, the Netherlands and Sweden.
  • The EU called it a deliberate attempt to disrupt the bloc's food supply.
