Retail giants Ahold Delhaize and Colruyt confirmed the breaches, which follow a similar pattern of sabotage observed in France last month. Security analysts trace the root cause to internet-connected refrigeration hardware manufactured by the Danish firm Danfoss. These units, which no longer receive vital security updates, were flagged as high-risk targets by the cybersecurity firm Claroty as early as August.

Cyberattack Wave Targets European Supermarket Refrigeration Systems
A surge of targeted cyberattacks has crippled refrigeration units across Belgium, Ireland, Luxembourg, and Sweden, forcing major retailers to discard massive quantities of spoiled food. Hackers systematically manipulated temperature settings to initiate defrost cycles, exposing critical vulnerabilities in the connectivity of essential supermarket infrastructure.
The incidents highlight the fragility of the modern food supply chain when faced with remote digital interference. This disruption mirrors the 2025 attack on UNFI, which caused widespread shortages across the United States. Meanwhile, U.S. Department of Defense officials are investigating potential breaches of military base freezers, with authorities examining possible links to state-sponsored actors previously associated with attacks on domestic water infrastructure.
