Reported Freezer-Control Hacks Disrupted About 700 French Supermarkets

Summary
A reported Oct. 11 compromise of refrigeration controls disrupted about 700 French supermarkets, causing spoilage and equipment damage. Internet-accessible Danfoss controllers with default credentials were cited as an exposure, but investigators have not confirmed the ḁ
Key points
- An unknown attacker reportedly compromised refrigeration controls on Oct. 11, triggering extended defrost cycles in about 700 French supermarkets.
- The incident reportedly caused millions of euros in damage, spoiled food, damaged equipment and, in some cases, fires.
- The article names Danfoss controllers and Dixell and Copeland XWEB systems; investigators have not publicly confirmed the initial access vector.
- Many Danfoss controllers reportedly had internet-accessible web servers and used default credentials: “admin” and the current date as the password.
- CERT-FR recommended changing default passwords, factory-resetting compromised equipment and updating firmware; Danfoss said many affected products were legacy systems no longer receiving updates.
- Similar refrigeration attacks were reported in other European countries in November. A separate attack on three French blood banks was stopped before plasma was damaged.
- Experts cited shared remote-access configurations and internet exposure as risks, and recommended removing internet exposure where possible and securing access points.
