Hungarian Tisza supporters mapped online – Fidesz politician visited one person’s home: Data leak scandal deepens

The scandal surrounding personal data leaked from the Tisza Party’s mobile application continues to escalate. In October, the personal details of around 200,000 registered users — including names, home addresses, email addresses and even geographic coordinates — became public. Now, these data have been turned into an interactive map, allowing users to search street-by-street or even house-by-house for people who used the Tisza Világ app, or to look up individuals by name and address.

This type of listing raises not only data protection concerns but serious personal safety risks. The combination of political affiliation and home address constitutes a category of sensitive personal data that should be protected — not displayed on a public map.

We do not publish the link to this site and strongly advise against attempting to access it. The National Authority for Data Protection and Freedom of Information (NAIH) has made it clear: even news articles that include a link to the leaked database could be unlawful (as seen in the case of Magyar Nemzet).

A dangerous precedent: When political preference is linked to home address

The map can easily facilitate targeted harassment or intimidation. If someone knows exactly where a political opponent lives, situations can escalate quickly to personal confrontation.

This is not a theoretical risk:

Balázs Németh, spokesperson of the Fidesz parliamentary group and a media personality, recently appeared in a video outside the home of a Tisza Party activist, implying that he knew the person’s address. The individual in question perceived the incident as a threat.

There was no explicit verbal threat, but the message conveyed was clear: “We know where you live.”

According to legal experts cited by Telex, such actions may constitute misuse of personal data. If the intent is intimidation, it may even amount to a criminal offence.

  1. Oh no!
    News organisation, that wrote to people, telling them they want to publish their response published their response, that included them stating their own names in the mail. Somebody publicizing what they told they will, before getting the response. Oh the humanity!

    It’s almost as bad as Tisza not protecting their privacy, and causing the leak in the first place…. or not.
    Can’t we just agree, that Tisza made a mistake, that causes foreign intel agencies to have a leverage on prominent figures, and as such caused a national security issue? Can we just agree to that, and work together to mitigate the damage, rather then going to conspiracy-theory-land, or is the opposition too hate filled to accept help saving themselves?

    • You would think, Dear Márk, that Tisza Party leaders, posing as Hungary’s foremost intellectuals operating in the political realm, would be aware that everything communicated on an electronic medium is tatamount to shouting in the public square.
