Mix TXTVALID Leak Raises Identity Theft Risk for 5,695 Users

HEROIC's threat intelligence team identified a combolist named "Mix TXTVALID" circulating on Telegram, dated April 17, 2026. The file contains 5,695 records pairing email addresses with plaintext passwords and the URLs those logins belong to.

Why the Mix TXTVALID Leak Is Dangerous

The name "TXTVALID" suggests these credentials have already been validated as working logins. Because the passwords are stored in plaintext, an attacker can try each pair against other websites right away, with a strong chance of success since the list appears to have been pre-checked.

What Was Exposed in the Mix TXTVALID Combolist

• Email addresses
• Plaintext passwords
• URLs of the websites or services the credentials belong to

Why This Combolist Matters

When a validated password unlocks an email or financial account, the risk goes beyond that one login. Attackers can use email access to reset passwords on other services, open new accounts in someone's name, or make fraudulent purchases, turning a single reused credential into a broader identity theft problem for the 5,695 people on this list.

How a Combolist Like This Works

A combolist mixes email or username and password combinations from multiple sources, such as older breaches, stealer logs, or prior credential-stuffing attempts, into one file. Validated, or "valid," lists like this one are more valuable to attackers because someone has already confirmed the credentials still log in successfully, saving buyers the trouble of testing them first.

Check If You Are Affected
