European supermarket fridges got hacked. Again. Here's what to know

Mysterious cyberattacks on European supermarket fridges have caused officials to scramble to determine the details, resulting in millions of dollars (euros) in food spoilage. One Swedish supermarket had its fridges set to 50 degrees Celsius (122 degrees Fahrenheit) after being hacked. This incident is a repeat of earlier attacks on refrigeration systems in France, Belgium, and the Netherlands, affecting hundreds of supermarkets and independent stores.

Supermarkets in at least six European countries, including Sweden, Belgium, Luxembourg, Ireland, Italy, and Estonia, reported problems on Monday. The attacks highlight the risks of connecting devices to the internet, as they can serve as entry points for hackers. Experts warn that many organizations are neglecting the security of their connected systems while investing in new technologies like AI and digital transformation.

In the latest attack, hackers exploited vulnerabilities in outdated remote control modules and default passwords. British officials warned that poor cyber hygiene, such as weak passwords, continues to put organizations at risk. However, there is no evidence that artificial intelligence was used in these attacks.
