Tisza Világ App Data Breach Exposes 198,551 Records

HEROIC analysts identified a data breach affecting Tisza Világ, a political community platform, exposing 198,551 records as of October 6, 2025. The exposed data includes email addresses, usernames, full names, and phone numbers. If you have ever registered on this platform, the only way to know for certain if your information was included is to scan your email.

Why This Combination of Data Is Risky

An email address paired with a username, full name, and working phone number gives a scammer enough detail to craft a message that feels personal rather than generic. That combination can be used to send convincing phishing emails or text messages, or to place phone calls that reference a person's real name to build quick trust before asking for more sensitive information.

Account Details Involved In This Exposure

• Email addresses
• Usernames
• First names
• Last names
• Phone numbers

Why Affected Members Should Pay Attention

Because this data ties a real name and phone number to a specific platform membership, affected individuals may be targeted with messages designed to look like official communications from the platform itself. Treating any unexpected request for further personal details, even one that appears to come from a familiar source, with caution is a reasonable precaution.

How This Kind Of Exposure Happens

In an incident like this one, records are taken directly from a platform's own systems rather than gathered one at a time. HEROIC analysts found this data circulating after it had already been pulled from internal records, reflecting exactly what the platform stored about its members.

Was Your Tisza Világ Account Exposed?

The fastest way to check is to scan your email for a match. If your information appears, stay alert for unsolicited emails, texts, or calls that use your real name or phone number to appear legitimate, and avoid sharing any additional personal details until you have verified the source independently. This applies to personal and work email addresses alike.
