Cyberattacks hit European grocers: French supermarket freezers hijacked, Dutch and Belgian stores disrupted
Attackers hijacked Danfoss refrigeration controllers at hundreds of French supermarkets, spoiling frozen stock; Ahold Delhaize separately hit by disruptive incident.
Attackers remotely hijacked Danfoss refrigeration control systems overnight at hundreds of French supermarkets including Intermarché, Netto, Super U, Leclerc, Carrefour Market and Monoprix, warming freezers and destroying chilled/frozen goods with per-store damage of tens to hundreds of thousands of euros. Claroty Team82 disclosed flaws in Danfoss AK-SM 800A and Copeland XWEB Pro web management interfaces in August 2026 that were since patched, but it is unconfirmed whether they were exploited here. Separately, Ahold Delhaize confirmed a security issue disrupting Albert Heijn, Etos, Gall & Gall and Delhaize stores in the Netherlands and Belgium, halting distribution centers and knocking websites and apps offline.
