A fresh wave of cyberattacks has hit Europe’s supermarket refrigerators, destroying food across countries

A second wave of cyberattacks has hit supermarket refrigerators across Europe, causing temperature settings to be changed to defrost and spoiling food at dozens of stores in Belgium, Ireland, Luxembourg, and Sweden. The attacks follow a similar hack in France last month that affected hundreds of supermarkets. Security researchers had previously warned about the vulnerability of internet-connected refrigerators made by Danfoss, which no longer provides security updates. The hacks highlight the potential for cyberattacks to disrupt the food supply chain, as seen in a 2025 cyberattack on food distributor UNFI that led to food shortages and empty shelves in the US. US military bases may have also been targeted by Iranian hackers.
