German intelligence agencies warn that Russian espionage is becoming more "massive" and "aggressive" The German Military Counterintelligence Service (MAD) reports that Russia employs diverse methods: sabotaging military ships and infrastructure, cyberattacks, spying on military property, and using advanced drones resistant to electronic jamming. A targeted disinformation strategy is also in use. Russian special services use Cold War-era tactics enhanced by modern technology. They target individuals with Russian roots or ties to gain trust. Bundeswehr soldiers with dual citizenship may be recruited or blackmailed.
