How the Mix Mail Combolist Compiled 3,812 Stolen Email Logins

HEROIC analysts identified a combolist file named Mix Mail uploaded to a Telegram channel in April 2026. The name suggests the file blends email logins pulled from several different providers rather than one single service. It contains 3,812 records pairing email addresses with plaintext passwords and the URLs those accounts belong to. Why This Is Dangerous: Because the passwords are stored in plaintext, an attacker who downloads this file can start logging into these email accounts immediately, with no cracking required. Access to an email inbox often means access to everything tied to it, since most password reset links go straight there. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to the email accounts Why This Matters: A mixed combolist like this one is built specifically to maximize the number of working accounts an attacker finds, since pulling from multiple sources increases the odds of hitting a still-valid password. If your email and password are among these 3,812 records, an attacker could read your messages, reset passwords on other accounts, and use your identity to target your contacts through phishing emails that look like they come from you. How the Mix Mail Combolist Was Compiled: Lists like this one are usually assembled by combining smaller breaches, phishing kit results, and stealer logs from several unrelated sources into one file, then sorting or filtering by email provider or domain. The result is a broader, more general-purpose list that attackers on Telegram trade or sell, then run through automated login tools to confirm which of the 3,812 pairs still work before using or reselling the verified accounts. Check If You Are Affected: Run a free scan against HEROIC's database of more than 400 billion breached records to see if your email address appears in this leak or any other. If it does, change that password immediately, enable two-factor authentication on your email account, and update the password anywhere else you may have reused it.
