The digital breaches hit supermarket systems across Belgium, Sweden, Luxembourg, Finland, Ireland, Estonia, and France. Attackers remotely altered connected thermostats, raising cooling temperatures up to 50 degrees Celsius to destroy perishable goods. Securing this critical equipment remains difficult because applying necessary software patches often requires taking units offline, risking stock, while some units rely on exposed 4G connections. Investigators have not identified the perpetrators or confirmed a motive, as no ransom was demanded and no traceable malware was deployed.

The attacks have exposed how a seemingly ordinary part of the food supply chain can become a target when connected to the internet.
Unlike conventional cyberattacks that seek to steal information or extract money through ransomware, taking control of refrigeration systems can cause immediate physical damage, which is food getting spoiled, disruption of store operations and potentially affecting consumer confidence.
The European Union condemned the incidents as a “deliberate attempt to disrupt our food supply chain and undermine consumers’ confidence in it”.
However, no group had claimed responsibility, and investigators had not established who was behind the attacks or…
