SBU Uncovers Hungarian Military Intelligence Network in Western Ukraine On May 9, 2025, the Security Service of Ukraine (SBU) announced the exposure of a Hungarian military intelligence network operating in Zakarpattia Oblast.
This marks the first time in Ukraine’s history that the SBU has publicly revealed espionage activities linked to Hungary. According to the SBU’s official statement, the network was gathering intelligence on Zakarpattia’s military security. Its tasks included identifying vulnerabilities in the region’s ground and air defense systems and studying the socio-political views of local residents, particularly their potential reaction to the entry of Hungarian troops into the area. The SBU operation, conducted in the city of Berehove, resulted in the detention of two agents. During searches, authorities seized encrypted communication devices, maps of military facilities, and documents confirming the agents’ activities. The operation was carried out under the supervision of the Office of the Prosecutor General of Ukraine.
One of the detainees is a 40-year-old man from the Berehove district, recruited by Hungarian intelligence in 2021. He was activated in September 2024 to assess civilian and military reactions to a possible deployment of Hungarian “peacekeeping” forces, monitor arms trafficking, and track Ukrainian troop movements. He traveled to Hungary using forged medical documents, where he received cash and secure communication tools.
The second detainee, a former Ukrainian military servicewoman, provided information on aircraft, helicopters, and military infrastructure in the region. The SBU confirmed that the network was managed by a Hungarian military intelligence officer whose identity has been established. Efforts are ongoing to identify other members of the network. The detainees have been charged with high treason under martial law (Article 111-2 of the Criminal Code of Ukraine). They face life imprisonment with confiscation of property. This incident highlights ongoing attempts to undermine Ukraine’s sovereignty. The SBU urges citizens to remain vigilant and report any suspicious activities that may threaten national security.
