Russian state-linked hackers fully compromise Hungary’s Foreign Ministry networks.

In the spring of 2022 investigative reporting revealed that Russian intelligence services (including actors tied to the Federal Security Service (FSB) and Main Directorate of the General Staff of the Armed Forces of the Russian Federation (GRU)) had gained persistent and deep access to Hungary’s Foreign Ministry computer networks, including the secure “VKH” encrypted diplomatic network. According to former internal officials, by the second half of 2021 the attackers had compromised the MFA’s internal correspondence systems and had also infiltrated the encrypted channels used for classified diplomatic communication. The breach reportedly allowed Russian actors to monitor Hungarian diplomatic deliberations, strategy toward EU/NATO policy, and even sensitive communications with allied states. The MFA’s internal security cables (obtained by the investigative outlet) show that ministry staff were unaware for long periods that their systems had been infected, and standard devices and credentials had been silently leveraged by the intruders. The incident highlights the geographic dimension (Budapest/missions abroad) and typology (cyber intrusion enabling espionage), as well as the dynamics: long-term infiltration, low-visibility compromise, and exploitation of government networks rather than immediate destruction or overt kinetic strike.
