Cyberattack targets refrigeration systems at French supermarkets
An ongoing cyberattack is targeting the temperature‑regulation hardware supplied by Danfoss in major grocery chains. The intrusion affects refrigeration units that run on Danfoss software versions older than version 4, causing internal temperatures to rise. Reports say the breach is impacting less than one hundred Coopérative U locations and between 100 and 150 Intermarché stores. Store operators have mobilised response teams and specialist frigorists to address the issue, and a formal investigation has been launched. The Groupement Mousquetaires estimates the resulting losses at several million euros.
