Hackers remotely defrost food in supermarket fridges across Belgium, Ireland, Luxembourg and Sweden
Supermarket chains in Belgium, Ireland, Luxembourg and Sweden report cyberattacks that remotely set refrigeration units to defrost mode, with temperatures reaching up to 50oC and forcing large food write-offs. Around 40 Delhaize stores in Belgium were hit, along with Carrefour, Intermarché, Spar, ICA, Coop and SuperValue sites. The attacks follow a mid-October wave in France, where some stores were running outdated firmware on Danfoss refrigeration controllers, but it is unclear whether the same method was used.
Supermarket fridges in Belgium and Sweden overheated in suspected cyberattacks
Refrigeration systems at supermarkets including Delhaize, Colruyt and ICA stores were remotely set to around 50°C overnight on 2 November, with some stores blaming a cyberattack. Attackers reportedly switched evaporators into forced defrost mode, the same method used against hundreds of French stores in mid-October, which involved Danfoss equipment and caused fires and food losses.
