**Deck**: A coordinated cyberattack remotely altered fridge and freezer temperatures at more than 115 supermarkets and commercial sites in at least seven European countries, damaging food stocks and exposing how easily networked cooling systems can be turned against retailers.

A mass cyberattack on supermarket and commercial cooling systems left freezers failing and food spoiling in parts of Europe after hackers remotely changed temperature settings in network‑linked fridges and cold rooms.

Regional reports say the intrusion hit refrigeration systems in more than 115 supermarkets and other establishments across at least seven European countries. Attackers manipulated temperatures in remotely controlled fridges and freezers, causing them to warm up and forcing operators to discard large quantities of perishable goods.

Problems were confirmed in Sweden and Belgium, with similar incidents reported in Luxembourg, the Netherlands, Ireland, Estonia and Finland. The spread of affected sites across several countries suggests a shared control platform or vendor network may have been compromised, rather than a single national chain.

For shop owners and staff, the attack translated into direct economic loss. Meat, dairy and frozen items became unsafe to sell. Stores had to close aisles or entire branches while they cleared out spoiled products and recalibrated systems. Customers walked into empty or partially stocked shelves, and companies faced the cost of both lost inventory and emergency repairs.

Security specialists point to this incident as an example of risk to so‑called operational technology: industrial control systems such as digital thermostats and compressor controllers that are connected to wider networks for remote management. Once those interfaces are exposed or weakly protected, attackers can trigger disruption by changing basic settings rather than targeting more heavily defended assets.

Food supply chains in Europe depend heavily on such cold‑chain infrastructure from warehouses to local stores. An organized actor that understands where those systems are concentrated can inflict financial damage and reputational harm without ever touching power grids or payment networks.

This attack adds to earlier IT and cyber incidents affecting European retailers but stands out for its described scale: more than 115 locations in seven countries in a single night. That scale implies preparation and mapping of the targeted systems, whether by criminal groups or other actors.

Authorities and supermarket groups now have several urgent tasks: restore normal refrigeration at all affected sites, identify which remote‑access platforms or service providers were compromised, and decide how much detail to disclose while investigations are under way.

Signals to watch in the coming days include any public attribution by European governments, changes in how large chains manage remote access to cooling systems, and reports of similar temperature‑manipulation attacks in other sectors that rely on networked cold storage, such as pharmaceuticals and logistics hubs.
