Have I Been Pwned treats this breach as sensitive: it does not reveal publicly whether a particular address is in it. Only the owner of an address can check, after verifying it.
What happened
In late October 2025, data breached from the Hungarian political party TISZA was published online before being extensively redistributed. Stemming from a compromise of the TISZA Világ service earlier in the month, the breach exposed 200k records of personal data including email addresses along with names, phone numbers and physical addresses.
What data leaked
- Email addresses
- Names
- Phone numbers
- Physical addresses
- Usernames
What to do if you had an account
- Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
- Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
- Watch for scam calls and SIM swaps. Be suspicious of calls and texts that claim to be from your bank or a courier. Ask your mobile operator for a port-out or SIM-change PIN if it offers one.
