An investigation is underway in Denmark after a suspicious component was discovered in imported electronics intended for the country’s energy infrastructure. This incident, revealed by a Danish company, echoes similar cases in the United States, prompting increased vigilance within the energy sector.

The component was found during an external security check of the electronics, raising concerns about potential vulnerabilities. Green Power Denmark, an industry organization, confirmed that this is not an isolated incident but declined to specify the component’s capabilities or its country of origin.

While experts offer differing perspectives on the immediate threat, there is consensus on the need for heightened scrutiny. Bent Ole Gram Mortensen, an energy and supply law researcher, emphasized the risk of “kill switches” being incorporated into critical infrastructure, potentially enabling sabotage or unauthorized access to vulnerable systems. He suggested diversifying suppliers of critical components.

Brian Vad Mathiesen, a professor of energy planning, expressed less alarm but agreed on the importance of monitoring for backdoors and vulnerabilities. He cautioned against overreacting with excessive regulations, suggesting a balanced approach to maintaining security without hindering essential imports.

Danish security agencies, including PET and CFCS, currently do not perceive an imminent threat of destructive attacks on the energy infrastructure. However, they acknowledge the potential for rapid changes in the threat landscape, particularly in the context of international relations.

The current case has led the involved company to suspend cooperation with the foreign manufacturer pending the outcome of the investigation. Authorities are urging careful consideration of the origin of critical components to mitigate potential risks to national energy security.
