How the MIX_1 Combolist Dump Led to 9,868 Stolen Logins

The MIX_1 Combolist Leaked 9,868 Email and Password Pairs

HEROIC analysts discovered a combolist named "MIX_1" uploaded to Telegram on November 5, 2024. The file contains 9,868 records combining email addresses with plaintext passwords, along with the URLs the credentials were originally tied to.

Why This Is Dangerous

Because MIX_1 stores its passwords as plain, unencrypted text, anyone who downloads the file can read and use the credentials right away, no cracking tools needed. Paired with matching URLs, it tells an attacker exactly which website each login was meant for, making it easy to try the same credentials there first.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Combolists like MIX_1 are usually pulled together from a mix of older breaches, which is likely how it got its name. Because people often reuse the same password across multiple accounts, a single leaked password can lead to credential stuffing attacks that compromise email, banking, and shopping accounts all at once, opening the door to identity theft and financial fraud.

How a Combolist Like MIX_1 Gets Built

Criminals compile combolists by combining credentials pulled from many older breaches, phishing campaigns, and malware infections into one file, then distribute them for free or for sale on Telegram and dark web forums. Automated tools called credential stuffing bots then take a file like this and test every email and password pair against dozens of popular websites within minutes, flagging any that still work.

Check If You Are Affected

If you think your email might be part of this leak or any other breach, HEROIC's free breach scanner checks your address against a database of more than 400 billion leaked records. It takes seconds to check, and if you find a match, changing that password right away can stop an attacker before they get in.
