Hackers disrupt refrigeration systems at European supermarkets

A cyberattack targeted refrigeration and cooling systems across multiple supermarket chains in several European countries. Hackers gained remote access and changed temperature settings on freezers and cooling systems, causing significant operational disruption. The attack affected multiple supermarket chains simultaneously, suggesting a coordinated or widespread campaign. The incident highlights the vulnerability of operational technology (OT) and industrial control systems (ICS) used in retail environments. Food safety and product integrity may have been compromised due to improper freezer and cooling temperatures. This event underscores the growing threat to critical infrastructure and supply chain systems beyond traditional IT environments.
