Hungary’s Sovereignty Protection Office has warned that a recently leaked database linked to the opposition Tisza Party may pose a serious risk to national sovereignty. In a statement issued on Tuesday, the authority claimed that several profiles in the leaked material can be traced to Ukrainian IT professionals and companies with links to Ukraine’s cyber infrastructure and, indirectly, to US intelligence networks.
According to the statement, the database includes references to FS Group, a cybersecurity company group specializing in the protection, development and operation of systems considered vital to national security. The authority said the company has repeatedly won contracts from Ukrainian state institutions, including the national police, the interior ministry, the energy company Naftogaz and the Ukrainian central bank.
The office further alleged that part of the group is owned by a firm with connections to US intelligence services. Its cyber-intelligence systems are reportedly used by Ukrainian law enforcement, potentially granting access to police and international intelligence data.
The statement also mentioned PettersonApp, a software development company whose employees allegedly appear around the Tisza Világ application in tester or administrator roles. According to the authority, the company has links to extremist and anti-Hungarian neo-Nazi groups, and its head, Oleh Ostroverh, is described as a committed supporter of Ukrainian President Volodymyr Zelenskyy.
Leaked data reportedly show that one of the application’s administrators, Miroslav Tokar, is employed by PettersonApp. Based on these claims, the Sovereignty Protection Office said the Tisza Party must explain why it entrusted the development of an application used for political mobilization and the handling of Hungarian voters’ personal data to Ukrainian companies.
The authority argued that these firms are allegedly connected to the defence infrastructure and state institutions of a country at war, as well as to extremist, anti-Hungarian organizations. It described the data breach as one of the most serious personal data incidents in Hungary in recent years.
According to the statement, the leak exposed the names, phone numbers, email addresses, locations and residential data of more than 200,000 people, making them freely accessible and potentially usable by anyone.
