European Supermarkets Under Cyber Threat: The Urgent Need for Secure Remote Access Solutions
In recent weeks, supermarket chains across Europe have been facing a disturbing trend of cyberattacks that specifically target refrigeration systems. This uptick in malicious activity has raised significant questions regarding how retailers safeguard their essential operational technology while ensuring the continuity of critical remote services. The latest attacks, reported in countries such as Sweden, Belgium, and Luxembourg, come only weeks after similar incidents in France, where attackers successfully manipulated refrigeration equipment across hundreds of stores, leading to substantial food loss.
Michael Ferdinandsen, CEO of Secomea, a Danish industrial cybersecurity company that specializes in secure remote access, stated that the consequences of these breaches are particularly acute. Unlike traditional cyberattacks, which primarily focus on data theft or IT service disruption, these assaults on operational technology (OT) can result in immediate physical repercussions. When refrigeration systems are compromised, businesses can face spoiled food products, operational interruptions, severe economic losses, and risks to food safety itself.
Ferdinandsen emphasized, "These incidents underscore why cybersecurity must evolve beyond merely protecting information. When attackers interfere with operational technology, the consequences become physical." For retailers, the issue isn’t if they need remote connectivity—it’s about having sufficient control over who can access their critical equipment, what they can access, and what actions they’re permitted to take. The challenge at hand is not connectivity itself, but rather the oversight of access.
Modern refrigeration systems rely heavily on remote connectivity for optimal functioning. External service providers and maintenance technicians leverage this connectivity to monitor temperatures, respond to alarms, diagnose faults, and conduct maintenance across potentially hundreds or even thousands of locations. While this connectivity is essential for minimizing response times and preventing equipment failures, it also introduces potential entry points for attackers. This risk is compounded in scenarios where operational equipment is directly exposed to the internet or when remote users are granted unnecessarily broad access.
For supermarket chains that operate multiple locations, managing these various refrigeration systems alongside different external service providers complicates the situation further. Each provider might employ varying access methods, making it challenging for IT and security teams to maintain consistent oversight of who can connect to critical infrastructure.
Many organizations have made significant investments in securing their corporate IT environments. However, operational equipment often presents a distinct challenge. Ferdinandsen noted, "These systems were designed for reliability over years, sometimes decades. They weren't necessarily built with today’s connectivity and cybersecurity demands in mind. Applying traditional IT remote access methods without considering these differences can result in unwarranted exposure."
To protect refrigeration systems, it isn’t necessary to eliminate remote connectivity. Instead, retailers must adopt an approach that allows external technicians to perform essential maintenance tasks while still maintaining strict control and accountability over access to operational equipment. Secure remote access solutions designed specifically for OT can help address this challenge by controlling connections at the individual asset level rather than granting users broad access to the operational networks.
Secomea's architecture, crafted for OT environments, enables secure connections to operational equipment via Edge Gateways located near the assets themselves. Centralized access management, granular permissions, and audit logging empower organizations to oversee who can connect, which equipment they can access, and when.
An exemplary application of this technology can be seen in Denmark, where AK-Centralen, a specialist in refrigeration system monitoring, uses Secomea technology to facilitate remote oversight of refrigeration systems in over 1,500 supermarkets. This secure connectivity allows the company to conduct essential monitoring and maintenance tasks without needing direct access to the internal networks of these stores, demonstrating that efficient remote maintenance and robust cybersecurity controls can coexist.
The incidents prompt inquiries that extend well beyond supermarket refrigeration. From building management and energy systems to production machinery and logistical infrastructure, organizations increasingly depend on connected operational equipment maintained by external specialists. As these environments become more interconnected, consistent methods for managing third-party access, restricting permissions to necessary resources, and maintaining visibility over remote activities become imperative.
Secure remote access forms a crucial part of this protection strategy alongside vulnerability management, network segmentation, system upgrades, and continuous monitoring. "Organizations shouldn’t have to choose between keeping their operations running or keeping them secure," Ferdinandsen concluded. "The goal is to enable the remote support that modern operations rely on while providing the governance and control that IT and security teams need, especially when these systems directly impact physical operations."
Although the exact methods used in recent suspicious attacks remain under investigation, these incidents serve as yet another reminder that cybersecurity failures in operational environments can quickly escalate into business continuity crises.
