An ongoing cyberattack has struck major supermarket chains across Europe, disrupting refrigeration control systems. The attack has reportedly set units to continuously defrost at 50 degrees Celsius, a temperature normally used for only two hours per day. French retailers Intermarché, Leclerc, and Coopérative U have been affected. Dominique Schelcher, president of Coopérative U, confirmed the attack on Monday morning, describing it as "extremely serious" and stating that teams are mobilised to restore normal operation. "Attacking equipment essential for the preservation of fresh products and the food supply of the French is unprecedented. It is unacceptable," Schelcher wrote on social media.
Early reports estimate losses at close to 300,000 euros, with the potential to run into several million euros nationwide.
Separately, in the Netherlands, NOS reports that several supermarket chains experienced a cybersecurity incident on Sunday afternoon. Albert Heijn, Etos, and Gall & Gall have taken their websites offline, affecting deliveries. Electronic shelf labels have also been compromised, disrupting in-store pricing. Albert Heijn said in a statement: "We have immediately taken measures to protect our IT environment. Part of this involves the preventive temporary shutdown of a number of systems." Belgium's Delhaize chain, which belongs to Albert Heijn, has also reported disruption. Images online show stores in Amsterdam warning customers about price problems and the suspension of loyalty programs.
It remains unclear whether the two attacks are related or how widespread either incident is.
