The MIX_1 Dump Exposed 3,157 Email and Password Records

HEROIC analysts identified a combolist named "MIX_1" uploaded to Telegram, tied to a leak originally dated November 3, 2024. The file contains 3,157 records pairing email addresses with plaintext passwords, along with the login URLs those credentials are tied to.

Why This Is Dangerous

Because these passwords are stored in plaintext, anyone who downloads the MIX_1 file can read each one exactly as it was originally typed, no cracking or decryption required. Combined with the matching login URL, an attacker can go straight to the correct sign in page and attempt access right away.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

Why This Matters

Although the leak dates back to late 2024, credentials like these rarely stop circulating once they exist. Threat actors continue to trade and repackage old combolists like MIX_1 for use in credential stuffing attacks, testing the same email and password pairs against banks, email providers, and social media accounts. If any of the 3,157 affected people reused this password elsewhere, those accounts remain at risk today.

How Combolists Work

A combolist is a plain text file that lists email or username and password pairs, one per line, usually collected from older breaches, phishing pages, or malware infections. These files are traded and re-uploaded on Telegram channels long after the original leak, which is why a file dated 2024 can still resurface and cause harm in 2026. Attackers load combolists into automated tools that test each pair against many websites at once.

Check If You Are Affected

Don't wait to find out if your email address is one of the 3,157 in the MIX_1 file. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including this combolist, so you can see instantly if you were exposed and change any reused passwords before someone else does.
