New cyberattack on supermarket fridges sweeps across Europe

A coordinated cyberattack targeted supermarket refrigeration and freezer systems across multiple European countries on Monday, forcing stores in nations such as Sweden, Belgium, Luxembourg, and Ireland to discard spoiled food. The incident closely mirrors a similar attack that occurred in France the previous month, where hackers compromised supermarket cooling units and caused widespread food losses and fires.

Major European grocery groups, including Ahold Delhaize and Colruyt, as well as Swedish chains ICA and Coop, reported that temperatures in their units soared—with some freezers reaching up to 50 degrees Celsius. At least some of the impacted refrigeration systems utilized temperature control technology supplied by the Danish firm Danfoss, which has been actively working with customers to implement security fixes.

While no group has claimed responsibility, European authorities and cybersecurity experts view the incidents with deep concern as potential acts of hybrid warfare or sabotage. Experts noted that retail chains make easy targets because they manage vast networks of connected devices, and sophisticated actors can leverage advanced technologies like artificial intelligence to exploit vulnerabilities in industrial control panels.

EU officials emphasized that these deliberate attacks represent a serious attempt to disrupt the food supply chain and undermine consumer confidence. Retailers and store managers expressed frustration and alarm over the sudden disruptions, noting that the ability of hackers to remotely manipulate temperature logs highlights significant security gaps in everyday commercial infrastructure.

Investigative efforts are currently underway by national cybersecurity centers and police agencies across the affected countries. However, officials warn that tracing such attacks can be extremely difficult because unauthorized access to exposed control panels often leaves behind virtually no digital traces or financial extortion demands.
