How will European supermarkets turn off their refrigerators?

European supermarkets are facing a series of cyberattacks targeting refrigeration systems, causing significant financial damage. Following incidents in France, attacks have spread to seven other countries, raising concerns about food supply chain disruptions. EU Commissioner Christophe Hansen expressed deep concern over these attacks, which are suspected to be state-sponsored, possibly linked to Russian or North Korean hackers. Experts note that the attacks exploit outdated software in refrigeration units, which often lack timely updates due to operational challenges. This vulnerability is exacerbated by reliance on less secure 4G connections.
