Supermarket Freezers Across Europe Hit By Suspected Cyber-Attack

Several major grocery chains in Europe have reported unexpected temperature spikes in their refrigeration and freezer units overnight, sparking concerns over a potential cyber-security breach reminiscent of a prior incident in France. According to reports from European supermarket chains, cooling units failed to maintain proper temperatures, placing perishable goods at risk.

In Sweden, the Coop company informed a daily newspaper that six outlets experienced issues, while ICA acknowledged that a limited number of its locations faced overnight disruptions in their cooling infrastructure. Meanwhile, Dutch retailer Ahold Delhaize reported an IT-related incident affecting refrigeration equipment across multiple grocery locations in Belgium and Luxembourg. A company representative confirmed that cooling temperatures had risen and stated that a formal investigation is underway.

Media outlets in Belgium noted that dozens of retail sites were impacted, encompassing various convenience stores, minimarkets, and independent outlets. Technical teams were dispatched during the early hours to disconnect compromised hardware from electrical grids and prevent further issues. These sudden malfunctions mirror a previous large-scale event in France where unauthorized remote access disrupted cooling systems across hundreds of supermarkets, causing significant financial losses and the spoilage of large quantities of fresh meat, dairy, and frozen items.

During the prior French incident, investigators found that internet-connected refrigeration controllers had their settings altered remotely, overriding standard safety thresholds and disabling automated alarms. Security evaluations revealed that many commercial cold storage units rely on internet connectivity for remote diagnostics and maintenance, making them vulnerable when security updates are delayed or neglected. Official investigations and specialized cybersecurity agencies in France continue to probe the extent of those breaches, which also involved hardware from multiple manufacturers.

Unidentified hackers targeted supermarket cooling systems across multiple European nations, causing overnight temperature spikes.

Why it matters

This string of cooling system malfunctions highlights the vulnerabilities inherent in internet-connected retail infrastructure. As supermarkets across European supermarket chains increasingly rely on remote management tools for temperature control, security flaws can lead to substantial food spoilage and financial damage.
