Cyber-attacks hit supermarket freezers across Europe

Supermarkets across Europe are dealing with the aftermath of a widespread cyber-attack that targeted their refrigeration systems. Dozens of stores in seven countries, including Belgium, Luxembourg, Sweden, Ireland, the Netherlands, Estonia, and Finland, reported that their freezers and fridges had malfunctioned. In some cases, the temperatures were remotely turned up to 50 degrees Celsius (122 degrees Fahrenheit), which caused large amounts of food to spoil and forced stores to throw away valuable products.

This incident is very similar to an attack that took place in France last month. During that event, hundreds of supermarkets lost millions of euros worth of food. According to the BBC, Stephan Moelans, the CEO of Sabcobel—a company that manages systems for Delhaize supermarkets—confirmed that the incident was a cyber-attack. He explained that the hackers were able to switch the units to a "defrost" mode, which caused them to warm up. He noted that his company had been working hard to disconnect affected units from the internet to stop the problem.

Many modern supermarkets connect their refrigerators to the internet so that staff can manage temperatures and perform maintenance from a distance. While this is convenient, it also creates a security weakness. Experts suggest that these devices often lack strong protection. According to The Guardian, Rafe Pilling, a senior director at the cybersecurity company Sophos, compared the hack to "wearing rubber gloves and messing with the switches." He explained that the hackers did not need complex software or malware to carry out the attack; they simply used the existing remote access features to change the settings.

While no group has officially claimed responsibility for the attacks, officials are looking for answers. The European Union has strongly condemned the events, calling them a "deliberate attempt to disrupt our food supply chain." Christophe Hansen, the European Commissioner for Agriculture and Food, stated that while the overall food supply is not in danger, the impact on businesses and the amount of food waste are very serious. In Belgium, the prosecutor's office has launched a criminal investigation into the matter.

There is also concern that these attacks might not be limited to Europe. According to The Guardian, authorities in the United States are currently investigating mysterious freezer malfunctions that happened at several military bases in August. Officials in the US are working with their French counterparts to see if the American incidents are connected to the European attacks. Some experts believe that state-linked actors, such as groups connected to Russia or China, could be behind the disruption, as they may be trying to show their ability to cause trouble or create fear among the public.

For the supermarkets involved, the financial cost is high. One store manager in Belgium told the news website Het Laatste Nieuws that they lost 100,000 euros worth of food, not including the money lost from having to close the shop. Other major retailers, such as Carrefour, Coop, and ICA, have also reported issues. While some companies were able to limit the damage, others are still working to secure their systems. In Sweden, the National Cybersecurity Center has warned that there are many "exposed" devices—machines connected to the internet without enough protection—that need urgent updates.

This situation highlights a growing problem in the modern world. As more everyday items, such as ovens, washing machines, and heating systems, are connected to the internet, they become potential targets for hackers. John Billow, the head of Sweden’s National Cybersecurity Center, emphasized the need for businesses to update or "patch" their equipment to close these security gaps. A patch is a small piece of software designed to fix a problem or improve a program's security.

As of now, it remains unclear who is behind these attacks or if they will happen again. While no one has demanded money—which is common in many cyber-attacks—the psychological impact of seeing empty shelves and spoiled food is significant. For now, supermarket chains across the continent are working to disconnect their systems from the internet or add stronger security measures to ensure that their freezers stay cold and their food remains safe for customers.
