Supermarkets in Belgium and Sweden have reported disruptions to their freezer systems following a suspected cyber-attack, according to reports. The incident affected cold storage operations at retail locations, raising concerns about the vulnerability of connected infrastructure in the food supply chain.

The attack is the second of its kind to hit supermarket freezers across Europe, suggesting a pattern of targeting refrigeration and cold storage systems. Details about the scale of the disruption and which specific retailers were affected have not been fully disclosed.

Cyber-attacks on industrial and commercial refrigeration systems can cause significant operational problems, including food spoilage and financial losses. Such systems are increasingly connected to networks, making them potential targets for malicious actors seeking to cause disruption.

Authorities and affected companies are investigating the incidents. The recurrence of attacks on supermarket freezers in a short period has drawn attention to the security of operational technology used in retail and food distribution across Europe.

The disruption in Belgium and Sweden follows the earlier strike on cold storage systems, and the fact that freezer operations in two separate countries have now been hit has heightened scrutiny of the safeguards protecting refrigeration equipment in stores. Operational technology of this kind is often managed separately from ordinary office IT, yet it remains exposed to networked access, a factor that security specialists have repeatedly identified as a point of weakness in retail environments.

For retailers, the consequences of a freezer failure extend beyond the immediate inconvenience to shoppers. Stock held at controlled temperatures can become unsellable if storage conditions are compromised, and the losses mount quickly across a large store estate. The investigation now under way will need to establish how the attackers gained access and whether the same method was used in both countries. Until those findings emerge, the affected companies have not disclosed further details about the scope of the disruption or the specific retailers involved.
