Spreading Cyber Attack: European Supermarket Freezer Hack Widens to Seven Countries

A sweeping and coordinated cyber attack targeting commercial refrigeration systems has expanded across Europe, now impacting supermarkets in seven countries.

Key updates on the expanding digital sabotage include:

• Broader Geographic Reach: While France bore the initial brunt with hundreds of stores affected, recent reports confirm that the incident has spilled over into at least six other European nations. Approximately 40 supermarkets were hit across Belgium and Luxembourg, alongside smaller clusters of stores in Sweden, Ireland, the Netherlands, Estonia, and Finland.

• The Vulnerability Point: The attacks target internet-connected refrigeration management controllers (predominantly older models manufactured by Danish engineering firm Danfoss). Hackers have been remotely overriding automated cooling cycles, forcing freezers and display cases into continuous heating mode to deliberately spoil fresh and frozen inventory.

• Industrial Security Concerns: Cybersecurity agencies and food safety commissioners have labeled the wave of incidents an alarming example of the “weaponisation of food” infrastructure, highlighting the growing vulnerability of industrial Internet of Things (IoT) devices left exposed to the public internet without proper segmentation or patching.
