Hackers raise supermarket freezer temperatures across Europe

· Cybersecurity · European Union · United Kingdom

Supermarkets across Europe were hit by a second wave of cyberattacks that remotely raised fridge and freezer temperatures, spoiling food, with incidents reported from Estonia and Sweden to Portugal and Italy and in ten countries overall. Retailers rushed to upgrade systems and discard food. The UK's National Cyber Security Centre said it was working with affected food suppliers and that the national impact was minimal, while its chief warned the attack could be just the start of a wider threat. Security experts said the incidents may represent the "foothills" of a broader campaign against food supply chains.

Why it matters：Hacking physical cooling systems shows how cyberattacks can disrupt food supply and consumer safety, pushing retailers and governments to harden industrial control systems.
