In June 2025, German media sources WDR, NDR, and Süddeutsche Zeitung reported two significant cyber incidents targeting Bundeswehr suppliers. A Hessian satellite communication contractor experienced a ransomware attack potentially compromising confidential Bundeswehr classified and operational data, although the Bundeswehr later assessed limited damage. Simultaneously, an engineering firm in Lower Saxony working on sensitive Bundeswehr infrastructure and operational defense plans was hacked, with unknown data losses. German law enforcement, including state criminal police in Hesse and North Rhine-Westphalia, conducts forensic investigations. Security sources attribute the attacks to Russian cybercriminals, possibly sharing tools with Russian state intelligence, reflecting blurred lines between crime and espionage. The Bundeswehr Cyber Security Center and Military Counterintelligence Office oversee defense and mitigation efforts. In parallel, the Bundeswehr has faced an increase in DDoS and phishing attacks since the 2022 Russian invasion of Ukraine, attributed to Russian APT groups like GRU-affiliated APT28. Chancellor Merz publicly acknowledged Russia's ongoing hybrid warfare campaign targeting Germany, characterized by espionage, sabotage, and extensive disinformation operations.
