A cybersecurity analyst has discovered around 300 commercial fridge and freezer systems in Spain that are visible online. However, no attack has been reported in Spain thus far. Marcelino Madrigal, the analyst, searched for internet-accessible refrigeration and climate-control equipment in Spain following news of supermarket hacks across Europe.
He found the systems, which allow technicians to monitor temperatures, receive fault alerts, and adjust settings without physically visiting the shop or warehouse. The analyst stated that being "exposed" simply means the equipment can be seen and accessed from the internet, not that it is necessarily vulnerable. He did not attempt to gain unauthorized access due to potential legal consequences.
Madrigal emphasized that no conclusions can be drawn about the vulnerability of these Spanish units based on the current findings. National cybersecurity institute INCIBE stated that it is too early to determine how the attackers gained entry, as the recent nature of the attacks and lack of traceability. They also do not know if any Spanish equipment shares the same weaknesses as those reported in other countries.
French cyber emergency team CERT-FR named kit from Danfoss, Copeland, and Dixell among the systems compromised in France. Security experts have previously warned about vulnerabilities in Danfoss controllers in August. CERT-FR suggests that temperature-controlling systems should not be directly reachable from the internet, recommending technicians to use protected links instead.
Owners are advised to check software updates, passwords, and defrost settings, as French attackers reportedly manipulated defrost cycles to heat the units. Danfoss advises keeping supported systems updated and replacing models that no longer receive security patches. Spanish businesses with remotely monitored fridges, freezers, or cold rooms should inquire with their installers about internet accessibility and software updates.
