1,370 Passwords From the ‘mix 978’ Combolist Just Surfaced Online

In July 2026, HEROIC analysts identified a combolist file labeled "mix 978" that had just surfaced on a Telegram channel. The file contained 1,370 exposed records tied to United States based accounts, including email addresses, plaintext passwords, and the URLs of the sites those login pairs unlock.

Why This Is Dangerous

Every one of the 1,370 records in this file is a working login stored in plaintext and matched to the exact site it belongs to. There is no cracking or decryption required, an attacker can simply take the file and start testing the accounts right away.

What Was Exposed in the "mix 978" Combolist

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

A file of this size is more than enough to power a credential stuffing campaign. If any of these 1,370 passwords were reused on other accounts, attackers can use them to attempt account takeover on email, banking, or social media logins, opening the door to identity theft and financial fraud.

How a Combolist Like "mix 978" Gets Assembled

Combolists like this one are built by pulling email and password pairs from older breaches, phishing pages, or stealer malware infections, then merging them into one file. The "mix" naming convention often signals that the credentials were pulled from multiple sources and combined into a single batch before being numbered and shared on Telegram.

Check If You Are Affected

A newly surfaced combolist like this one can spread quickly once it starts circulating. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can find out in seconds whether your credentials were part of this leak and change your passwords before anyone else does.
