Attackers Reportedly Hack Supermarket Fridges and Raise Temperatures to 50°C
Attackers remotely compromised Danfoss refrigeration controllers in ~150 French supermarkets, setting temperatures to 50°C and causing major food spoilage and financial losses.
French supermarket chains Intermarché, E.Leclerc, and Système U experienced a cyberattack targeting Danfoss refrigeration control systems overnight October 11-12, with attackers remotely setting temperatures to 50°C and triggering continuous defrost cycles across affected stores. Approximately 150 Intermarché stores were impacted, with potential losses reaching hundreds of thousands of euros from spoiled food stock. Coopérative U CEO Dominique Schelcher confirmed criminal activity affected refrigeration production systems. The exact intrusion method, responsible group, and whether a known vulnerability was exploited remain unconfirmed, though older software versions are suspected.
