The MIX_1 Leak Happened in 2024. HEROIC Just Found 12,680 Records.

The MIX_1 Combolist From 2024 Just Surfaced With 12,680 Records

HEROIC analysts uncovered another combolist file labeled "MIX_1," originally uploaded to Telegram on November 11, 2024. This version contains 12,680 records pairing email addresses with plaintext passwords, along with the URLs those credentials were tied to.

Why This Is Dangerous

Passwords in this file are stored in plain, unencrypted text, so anyone who downloads it can use the credentials immediately, no cracking required. Matched against real email addresses and site URLs, it gives an attacker a direct map of which login works where.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Even though this data was compiled back in 2024, it remains just as dangerous today if the passwords haven't been changed since. Attackers use combolists like this one to run credential stuffing attacks against email providers, banks, and shopping sites, and a password that worked in 2024 often still works now. That kind of access can quickly escalate into account takeover, identity theft, or financial fraud.

How a Combolist Like MIX_1 Circulates

Combolists are compiled from a mix of older breaches, phishing operations, and malware infected devices, then repackaged and shared or resold across Telegram channels and dark web forums. A list can sit quietly for months or years before it resurfaces in a new post, gets combined with fresher data, or gets picked up by criminals running automated login attempts at scale.

Check If You Are Affected

If you haven't changed your passwords since 2024, now is a good time to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, so you can see in seconds whether your email shows up in this leak or any other, and update any passwords you're still reusing.
