How have hackers managed to attack supermarkets in several European countries?

Recent cyberattacks on supermarkets across Europe have highlighted significant cybersecurity vulnerabilities in refrigeration systems. The attacks, affecting countries like Belgium, Sweden, and the Netherlands, exploited outdated software and poorly secured remote management interfaces. Analysts noted that many systems were accessible online and lacked necessary security updates. In previous incidents, hackers manipulated temperatures in refrigeration units, leading to substantial financial losses. Danfoss, a key player in the refrigeration sector, has advised clients to enhance their security measures. The situation has raised concerns about food safety and the resilience of supply chains, prompting scrutiny from the Spanish distribution sector.
