European intelligence and security services warn that Russian intelligence is actively preparing sabotage and hybrid attacks targeting defense industries and critical infrastructure across the continent, following a series of disrupted plots and suspicious incidents since 2022. According to warnings from Danish and Norwegian security authorities, alongside analysis from military experts, these operations aim to pressure European nations supporting Ukraine and test allied response thresholds.
Danish Intelligence Warns of Active Sabotage Plans Against Defense Industry
The Danish Politiets Efterretningstjeneste (PET) has disclosed that Russian security services are actively preparing sabotage operations aimed directly at Denmark’s defense sector. According to Berlingske, Emil Græsholm, head of counterintelligence in the Danish intelligence service, stated that the sites and preparations are concrete enough to cause genuine concern. Intelligence assessments indicate that businesses linked to Danish military assistance to Ukraine are primary targets, with arson cited as a potential tactic. Additionally, Danish intelligence reports that Russian handlers have attempted to recruit ordinary citizens to execute operations.
PST and Nordic Experts Warn Norway Faces High Risk of Hybrid Attacks
Norway’s Politiets Sikkerhetstjeneste (PST) states in its open threat assessment that Russian intelligence may target property and logistics infrastructure tied to Ukraine support to create social unrest and weaken political will. Ola Kaldager, former head of the Norwegian intelligence group E14, notes that military and northern strategic areas represent primary targets. Jacob Kaarsbo, a security and defense analyst and former chief analyst at the Danish Defence Intelligence Service, points out that ignoring Norway and Denmark would defy the established European pattern. Since 2022, researchers like Professor Peter R. Neumann of King’s College have tracked 18 attacks, attempted attacks, and suspicious incidents against Western military supply chains and weapons companies, with four cases strongly confirmed as Russian-directed.

Escalating Tactics Include Assassination Plots Against Defense Executives
The threat landscape extends beyond traditional sabotage into lethal operations targeting key defense industry leaders. Jacob Kaarsbo highlights that German police and intelligence uncovered a concrete assassination plot against Stefan Thumann, the head of German drone manufacturer Donaustahl, which was successfully averted following warnings from allied intelligence services. This follows the 2024 exposure of a Russian plot to liquidate Armin Papperger, CEO of German defense giant Rheinmetall, which was confirmed by NATO official James Appathurai as part of a broader campaign against European armament executives. Analysts attribute this heightened risk appetite to a pressured Vladimir Putin seeking to escalate tensions and manufacture external threats to support potential domestic mobilization.
