Cyberattack overheats refrigeration systems at hundreds of French supermarkets
A cyberattack on remotely managed refrigeration systems forced equipment at roughly 500 French supermarkets to heat dramatically, spoiling fresh and frozen food and disrupting operations. The affected retailers included Intermarché, Netto, Carrefour, Monoprix and E.Leclerc; some units reached 50C, and food was removed where safety could not be guaranteed. The attack targeted older Danfoss systems whose security software could not be updated against a known risk. French prosecutors have opened a cybercrime investigation, but the perpetrators and full losses remain unknown.
