Almost 800 Hungarian government email addresses and associated passwords are circulating online, revealing basic vulnerabilities in the security protocols of ministries involved in classified and sensitive work.

A Bellingcat analysis of breach data shows that 12 out of the government’s 13 ministries have been affected, which in some cases have exposed the confidential information of military personnel and civil servants posted abroad.

Among those affected were a senior military officer responsible for information security, a counter terrorism coordinator in the foreign affairs department, and an employee whose role was to identify hybrid threats against the country.

The revelations come as Hungarians head to the polls this Sunday to decide if Viktor Orbán, leader of the right-wing populist party Fidesz and the country’s longest-serving prime minister, will be elected to a fifth consecutive term.
