Cyberattacks Manipulate Grocery Refrigeration Systems, Spoiling Food at 400+ Stores

Summary
Attacks manipulated refrigeration systems at more than 400 grocery and retail stores, spoiling food and reportedly causing small fires. The actor is unknown; outdated firmware and exposed systems are cited as risks.
Key points
- Companies reported that attacks affected more than 400 grocery and retail stores in France; a Sekoia analyst told Reuters that Spain, Portugal, Poland, Germany, and Belgium were also affected.
- Attackers reportedly changed refrigeration controllers to heat cold-storage units, while extending defrost cycles to make the heating appear routine.
- Two supermarkets in Alsace reported combined losses of 270,000 euros; broader losses could reach many millions, but that figure is an estimate.
- Danfoss said affected units included end-of-life AK-SM 800 and AK-SC355 systems. The article says researchers had disclosed and Danfoss patched vulnerabilities in AK-SM 800A, but customers had to install firmware updates.
- France's CERT-FR also identified Dixell/Copeland XWEB controllers in the attacks; the article does not establish which vulnerabilities or firmware versions were involved.
- Les Mousquetaires said its attack occurred through a refrigeration-system service provider. The attacker and motive remain unknown.
- The article recommends removing control systems from direct Internet exposure, restricting remote access, using firewall rules and two-factor authentication, and replacing unsupported firewalls. Separate US military commissary outages have not been attributed to an attack.
