Die Zeit reported on August 5 that Russian intelligence services likely planned to assassinate Stefan Thumann, CEO of the German drone startup Donaustahl, which supplies Ukraine with reconnaissance and kamikaze drones. German security services had been alerted by a foreign intelligence agency in December 2025, leading to the arrests of two suspected spies in March 2026. The investigation underscores ongoing Russian targeting of European defense firm leaders, even as Thumann remains under heightened police protection.
The Plot Against Thumann
In December 2025, a foreign intelligence service alerted German authorities that Stefan Thumann, CEO of the drone manufacturer Donaustahl, was at high risk. Bavarian police detained a Ukrainian citizen, Sergey N., who had filmed Thumann's residence in Strasskirchen. After his release, investigators discovered he had communicated with a Russian intelligence agency and also observed Thumann's father. A Romanian citizen, Alla S., then continued the surveillance from North Rhine-Westphalia. Both were arrested in March 2026 on espionage charges; prosecutors did not include the assassination attempt in the arrest warrant, viewing the duo as expendable agents recruited online for sabotage and spying.
Wider Pattern of Threats
Die Zeit reports that another German defense company is also under Russian surveillance, and its executive may be at risk. In early June 2026, Serbian border guards stopped a truck with hidden compartments for explosives at the Hungarian border; the drivers' phones contained contacts with a Russian intelligence service. The vehicle was reportedly headed for Bavaria, home to Donaustahl, Quantum Systems, and Helsing. In July 2024, CNN revealed that U.S. and German intelligence had foiled a plot to kill Armin Papperger, CEO of Rheinmetall, part of a series of Kremlin-planned attacks on European defense industry leaders.
What's Next
The Bavarian state prosecutor's investigation into the espionage case continues, with no public timeline for charges beyond espionage. It remains unclear whether the assassination plot against Thumann was definitively abandoned or merely postponed as security measures increase.
