Over a Dozen Russian Agents Operating Under Diplomatic Cover in Hungary

Hungarian intelligence services have identified more than 12 Russian intelligence officers operating within the country under diplomatic cover, according to reporting by the news outlet Novinky on May 18, 2026.

The report indicates that these individuals are utilizing their official positions within Russian diplomatic missions to conduct espionage activities. By operating under diplomatic cover, these agents gain access to legal immunities provided by the Vienna Convention on Diplomatic Relations, which protects diplomats from prosecution and arrest in the host country.

The presence of such a network in Budapest is viewed as a strategic effort by Moscow to gather intelligence and exert influence within the European Union and NATO. Hungary’s membership in both organizations makes it a critical location for monitoring the internal deliberations and security postures of Western allies.

Intelligence assessments suggest that these officers are likely affiliated with Russia’s primary intelligence services, such as the SVR (Foreign Intelligence Service) or the GRU (Main Directorate of the General Staff of the Armed Forces). These agencies frequently embed officers in embassies to facilitate clandestine operations, recruit local assets, and maintain communication with other intelligence networks across Europe.

The identification of more than a dozen agents suggests a scale of operation that exceeds typical diplomatic requirements. In many cases of diplomatic espionage, host countries monitor the ratio of diplomatic staff to the actual administrative needs of the embassy to identify potential “undeclared” intelligence officers.

The discovery of this network comes amid a broader pattern of increased scrutiny toward Russian diplomatic activity in Central and Eastern Europe. Several EU member states have previously expelled Russian diplomats suspected of espionage as part of efforts to harden national security against foreign interference.

Under international law, when a host country determines that a diplomat is engaging in activities incompatible with their status—such as espionage—the standard procedure is to declare the individual persona non grata. This requires the sending state to recall the person or terminate their functions within a specified timeframe.

The current status of these identified agents remains under review by Hungarian security authorities. The report does not specify whether immediate expulsions have been ordered or if the intelligence services are continuing to monitor the network to map its full extent and identify its local contacts.
