Ahead of next spring’s election in Hungary, opposition leader Péter Magyar is facing another scandal. Sensitive personal data of more than 200,000 users who downloaded and registered for the Tisza Party mobile application was leaked to the public.
Even more embarrassing, the leaked database of the “Világ” phone app shows users included various current judges and a large number of prominent politicians and public figures of the pre-2010 left, according to Magyar Nemzet. Remix News is not publishing their names, as this list was obtained through an illegal hack. Furthermore, the presence of these names does not necessarily mean any of these individuals even necessarily supported or support Tisza.
Mandiner has also confirmed that the identities involved are reported to include numerous deposed opposition politicians, former opposition intellectuals, and “independent-objective journalists.”
An analysis out of Ellenpont also shows that the list includes several well-known figures from the Gyurcsány–Bajnai era, which may indicate that the old left-wing elite is trying to reorganize around the Tisza Party and Péter Magyar. However, again, there is no evidence that those signing up for the app were necessarily Tisza supporters.
Remix News reported back in October about the data leak, which at the time had reportedly impacted just 18,000 users. Among those exposed was the Ukrainian developer Miroslav Tokar, an admin for the system developed by the Ukrainian company PettersonApps.
The CEO of PettersonApps is Oleh Ostroverkh, a supporter of Zelensky and a member of the supervisory board of the NGO Defense Robotics UA. This NGO is known to have close ties with the Ukrainian army’s “Da Vinci Wolves” battalion, particularly in the development, deployment, and tactical testing of ground-based drones.
According to Ellenpont, the Tisza leak is the biggest data management scandal since the change of regime, with it exposing collusion between Péter Magyar and the old Gyurcsány-Bajnai guard — as well as with Ukraine.
Magyar has also actively worked with Brussels, promising to fall in line with their agenda were he to come to power. To this end, the European Parliament voted to allow the Tisza leader and MEP to keep his immunity, effectively protecting him from prosecution in three separate cases and paving the way for his run in the 2026 election in Budapest.
