Albert Heijn sister chain hit as fridge hacks spread in Europe

Hackers were able to infiltrate refrigeration systems at multiple store locations across Belgium, Luxembourg, Sweden, and France overnight, causing temperatures to rise in fridges and freezers. At least 40 branches of Delhaize's sister chain Albert Heijn were impacted, weeks after a similar attack hit hundreds of French supermarkets.

Delhaize called it an "IT incident" and disconnected the refrigeration systems from the internet. Some store managers responded by bringing in refrigerated trucks to save their stock. Swedish supermarkets Ica and Coop reported a limited number of affected stores, with one Ica store setting its fridges and freezers to 50°. In France, the October 11 attack raised temperatures to 50° in hundreds of supermarkets using equipment from Danish manufacturer Danfoss, which noted most systems were outdated. The connection between the October attack and Monday's incident remains unclear.
