Cyberattack Disrupts Supermarket Cooling Systems Across Europe

• •A cyberattack on cooling systems affected supermarkets in Belgium and Europe.
• •Hackers manipulated temperature settings, causing food spoilage and financial losses.
• •Known vulnerabilities in Danfoss and Copeland devices were exploited in the attack.

On November 3, 2026, a cyberattack targeted cooling systems in supermarkets across Belgium and other European countries, including Delhaize, Carrefour, and Intermarché. The attack, which began around 2 AM, involved hackers altering the temperature settings of refrigeration units, causing significant disruptions. In some locations, temperatures in Estonian systems reached 50 degrees Celsius, leading to food spoilage and financial losses, such as an estimated €60,000 in discarded products at a Delhaize store. The attack is believed to exploit known vulnerabilities in devices from Danfoss and Copeland, which had been previously flagged for security issues. Despite warnings from Danfoss to disconnect systems from the internet, many businesses failed to act, leaving them vulnerable. As of now, Delhaize has reported that its affected supermarkets are operating normally again, but the full extent of the damage across all impacted retailers is still being assessed.
