Summary

A Hungarian spy ring operated out of Hungary's embassy in Brussels and intensified its activities from 2015 to 2016. Hungarian intelligence officers stationed at the country's permanent representation in Brussels attempted to recruit EU officials, particularly targeting Commission officials of Hungarian nationality to collect detailed information related to the Hungarian government’s interests. The spy ring's existence became known among European Hungarian officials by 2015, which hampered their efficacy. The activities are understood to have stopped in 2016. The European Commission's investigation found no serious security breaches and could not attribute individual responsibility beyond the intelligence officers themselves. Olivér Várhelyi, Hungary's EU ambassador from 2015 and now European Commissioner for Health and Animal Welfare, denied awareness of the spy activities or being approached by intelligence services. The Hungarian permanent representation and Várhelyi did not comment on the investigation findings.

Classification

Confidence: High

The report confirms a foreign intelligence operation targeting EU officials with the goal of collecting sensitive information beyond diplomatic norms, constituting hostile espionage activity against EU institutions. The activity was state-directed and conducted through diplomatic cover, fulfilling hybrid warfare’s intelligence espionage criteria.
