Cyberattacks Disrupt Supermarket Refrigeration Across Europe

• •Cyberattacks targeted supermarket refrigeration systems in at least nine European countries.
• •Refrigeration units were set to 50°C, causing extensive food spoilage.
• •The attacks highlight vulnerabilities in food supply chains and cybersecurity preparedness.

In late October and early November 2026, coordinated cyberattacks targeted supermarket refrigeration systems in at least nine European countries, including France, Sweden, and Belgium. Attackers remotely set refrigeration units to 50°C (122°F), leading to significant food spoilage. The first wave occurred between October 11-12, impacting hundreds of French supermarkets, followed by a second wave on November 2, affecting stores in multiple countries. The refrigeration controllers involved were primarily manufactured by Danfoss, and while the number of exposed devices on the internet has increased, credible observations of these devices have decreased. No group has claimed responsibility for the attacks, and the method of intrusion remains unconfirmed. The incidents have raised concerns about vulnerabilities in food supply chains, particularly regarding the potential for ransom demands and the economic impact on grocery prices.
