According to the French magazine 'L'Express', Russia is leading a comprehensive secret campaign to acquire real estate located near military bases in various countries across Western Europe, planning to execute sabotage operations at an opportune time. The British newspaper Telegraph reported that Russian spies have turned scattered properties throughout Western Europe into a network of "Trojan Horses" intended to support a coordinated destabilization campaign.

The properties in question—which have raised suspicions among European intelligence agencies—include isolated chalets, urban apartments, abandoned schools, warehouses, and islands, all strategically located near military bases or critical infrastructure. This proximity potentially allows these real estate assets to be used for setting up listening posts or storing equipment, serving as launch points for sabotage operations.

European officials are warning of an increase in hostile actions attributed to Moscow, which is considering testing a "gray area" strategy—carrying out dangerous acts to disrupt transport, energy, or communications in Europe without provoking direct military retaliation from NATO. This situation highlights the escalating tensions between Russia and the West and raises concerns about the security of vital infrastructures in Europe, with Finland being an initial focal point.
