French Supermarket Chain Intermarche Hit by Cyberattack, 150 Stores Targeted
Hackers altered temperature controls at more than 150 stores, forcing retailers to discard fresh and frozen goods and suspend online orders.
- Hackers accessed French supermarket refrigeration systems overnight on Sunday, altering temperature controls at stores including Cooperative, Intermarche, Super, Leclerc, and Carrefour; at least 150 locations reported disruptions.
- Modern supermarkets increasingly rely on connected technology to monitor temperatures and manage stock, which allowed hackers to manipulate refrigeration equipment settings and break the cold chain. Perishable food including meat, fish, and dairy was put at risk.
- Financial damage could reach millions of euros due to discarded inventory, as stores cannot return compromised food to shelves if safety has been compromised. Teams are working with refrigeration specialists to restore normal operations.
- Separately, Dutch and Belgian shoppers faced service disruptions as Albert Heijn, Etos, and Gall reported website, app, and logistics issues on October 12; officials confirmed no evidence links this incident to the French attack.
- Cybersecurity researchers at Claroty identified vulnerabilities in Danfoss refrigeration controllers in August 2026, though manufacturers subsequently released firmware updates. No similar incidents have been reported in Spain, where supermarkets operate complex digital systems.
