What seemed like a science-fiction plot became reality in Europe. In October 2026, supermarkets in different regions of France were hit by cyberattacks that compromised the refrigeration systems of hundreds of stores. During the night, intruders remotely changed the settings of refrigerators, cold rooms and freezers, raising temperatures to approximately 50 °C.
The problem was not limited to France. In early November, new incidents were reported in Belgium, Sweden, Ireland, Finland, Luxembourg, Estonia and the Netherlands. Supermarket chains had to throw away large quantities of food, including meat, dairy products and frozen goods. At one Belgian store, losses reached approximately 100,000 euros.
Investigations pointed to vulnerabilities in control systems used in the refrigeration equipment, including software from the Danish manufacturer Danfoss. Some of the devices were running outdated versions without security updates, while others were exposed directly to the internet with insufficient protection mechanisms.
But one question stands out: what did the attackers gain from this? Unlike traditional attacks, in which criminals steal banking information, hijack files or demand payment to release systems, no public claim of responsibility or known ransom demand has been made in these incidents so far.
There is also an indirect economic dimension: attacks of this nature can serve as a demonstration of technical capability for criminal groups, build reputation among attackers or lay the groundwork for future extortion. However, there is no public evidence that this was the goal of those responsible for the European incidents.
Although artificial intelligence can be used to automate vulnerability research, develop tools and coordinate cyber operations, there is no confirmation that it was used in these attacks. Experts point out that the flaws exploited may be simple enough to allow intrusions without sophisticated technological resources.
The episode leaves an important warning: connecting equipment to the internet is not just a convenience. Refrigerators, cold storage rooms, air-conditioning systems, security cameras and even smart home devices can become entry points for intrusions. Software updates, strong passwords, restricted remote access and protected networks are essential measures to reduce these risks.
Perhaps the most worrying damage is not only the value of the discarded food, but the demonstration that a digital vulnerability can cause physical and economic consequences in the real world. In an increasingly connected society, protecting systems is no longer a concern exclusive to technology companies and has become everyone's responsibility.
