Cyberattack impacts cooling systems in Swedish supermarkets

On November 2, 2026, major Swedish supermarket chains ICA and Coop reported a sudden, unauthorized temperature increase in their freezers and refrigerators. At least one location explicitly attributed the incident to a cyberattack, noting that temperatures in its cooling units were remotely adjusted to 50 degrees Celsius.

The incident affected a limited number of outlets, with the Coop group confirming that six of its stores experienced similar malfunctions overnight. These events mirror a large-scale cyberattack reported by French authorities last month, where hackers gained control over cooling systems in hundreds of supermarkets, leading to widespread food spoilage and localized fires due to technical system vulnerabilities.

While the full scale of the disruption in Sweden is still being assessed, the incidents have highlighted the growing security risks associated with interconnected commercial refrigeration systems. Companies and authorities are currently investigating the extent of the breach, but no further details regarding suspects or specific methods of infiltration have been released to the public at this stage.
