French defense intelligence has directed executives supplying equipment to Ukraine to tighten their personal and corporate security following confirmed assassination plots and espionage targeting European defense contractors. The Direction du renseignement et de la sécurité de la défense contacted French defense leaders in late September to urge heightened precautions regarding private security and immediate family circles, according to reporting published by L’Express.
Escalating Threats Across Europe
The warning arrives as European defense manufacturers face mounting security threats linked to their material support for Kyiv. In Germany, Rheinmetall CEO Armin Papperger has operated under heavy armed protection since July 2024, when American intelligence uncovered a Russian state-backed plot against his life. Papperger leads a major European producer of artillery and tank ammunition utilized extensively by Ukrainian forces.
A second German defense executive, Donaustahl CEO Stefan Thumann, received warnings from authorities regarding a similar alleged Russian plot targeting his life. Donaustahl manufactures attack and reconnaissance drones supplied to Ukraine. Thumann reported living under 24-hour guard while managing his enterprise remotely after German prosecutors arrested two suspected operatives in March accused of conducting surveillance to prepare an assassination.
French Counter-Intelligence Advisories
French counter-intelligence services translated these international developments into direct advisories for domestic contractors, particularly firms specializing in anti-drone technology and military artificial intelligence. A French military artificial intelligence startup executive confirmed receiving recommendations to upgrade personal security measures, commission comprehensive vulnerability audits, and retain former special forces personnel for protective details.
Vulnerability Profiles and Armed Protection
Aeronautics and defense expert Xavier Tytelman noted that French companies actively supporting military operations in Ukraine occupy a primary target profile for hostile intelligence services.
Espionage Incidents in the Domestic Sector
French defense contractors have integrated specialized security protocols into daily operations. Toulouse-based drone manufacturer Delair, which supplies observation unmanned aerial systems and loitering munitions to Ukraine, appointed a dedicated security officer two years ago. The firm encountered active espionage this summer when a 48-year-old Belarusian national was indicted under a Paris judicial investigation for filming a Delair prototype and transmitting footage to a Russian contact.
Operational Counter-Surveillance Habits
Security recommendations distributed by French authorities emphasize counter-surveillance habits designed to obscure executive routines. Guidance advises changing mobile communication devices frequently, varying accommodation choices, omitting online reviews and photograph sharing, and randomizing transit schedules, meeting locations, and exercise routines to prevent targeted tracking.
The judicial inquiry into the Delair espionage incident proceeds under the Paris public prosecutor’s office, focusing on the collection and transmission of intelligence to a foreign power in a manner undermining national fundamental interests.
