Is Your Name in the Argentine Citizens Leak? 23,138,333 Entries

HEROIC analysts found a file holding 23,138,333 records dated August 29, 2025. The file carries Social Security numbers, first names, last names and gender, the kind of identity details that can be used to impersonate a person to a bank or lender.

It surfaced in an online channel where breach files are traded, and the sheer volume makes it easy to search, sort and reuse. Only a scan of your email can show whether your details are in this file.

What 23,138,333 Identity Records Make Possible

Identity numbers paired with a name and gender are among the most useful details for impersonation. Someone holding them can pose as a person when calling a service, asking for a change of contact details or applying for credit. Scale matters here, because a list this large can be searched, sorted and worked through in bulk.

Four Identity Fields and What Each One Opens Up

• Social Security numbers: act as a strong identifier that a scammer can use to sound like the person in official contact.
• First Name: makes a message feel personal from its first word.
• Last Name: lets a caller match the person to a formal record.
• Gender: adds a small detail that helps a fake message seem tailored.

Why the Scale Changes the Risk

Most leaks give an attacker a few hundred or a few thousand targets. This one gives a list large enough to automate much of the work. Identity fraud usually begins with one convincing call or form, and a list this size makes it cheap to try the same story on many people. These numbers rarely change, so the risk can stay open for a long time.

How Records Like These Are Gathered

This file is listed as a database, so its records were copied out of a system and pulled into one list. Identity records are valuable because the same fields work across many different services. Once shared, they circulate among traders who reuse the details.

Is Your Identity Data in the Argentine Citizens File?

Step one is to scan your email and review what it shows about you. Next, check your credit reports for applications you did not make, and be wary of calls that quote your name or identity number. Never share an identity number with someone who contacted you first.
