Cyberattacks on supermarket refrigeration systems have caused widespread food spoilage in at least nine European countries since October 2026.

Cyberattacks targeting internet-exposed refrigeration controllers have hit supermarkets across Europe, forcing units into defrost mode and raising temperatures up to 50°C. The incidents began with a wave in France on October 11 affecting hundreds of stores, followed by a second wave in November impacting stores in Belgium, Ireland, Luxembourg, Sweden, Estonia, the Netherlands, Finland, Italy and Portugal. Chains including Carrefour, Ahold Delhaize, Coop, ICA and SuperValu reported issues at dozens to hundreds of locations. No group has claimed responsibility, though hacktivists have made unverified claims. Agencies including CISA, FBI and ENISA have issued warnings urging immediate firmware updates to end-of-life Danfoss, Copeland and Dixell systems.
