One Telegram Post Exposed the ‘Mix’ Combolist’s 22,400 Passwords

HEROIC analysts found a combolist labeled "mix" that a Telegram user uploaded on 01-Sep-2024. The file contains 22,400 records of email and username and password credentials tied to accounts in the United States.

Why This Mix Combolist Is Dangerous

A generic-sounding name like "mix" doesn't make a combolist any less useful to an attacker. This file pairs 22,400 email addresses directly with plaintext passwords, meaning anyone who downloads it can immediately start testing those exact login combinations on other websites, with no cracking or guesswork needed.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

If your credentials are among the 22,400 in this file and you have reused that password on other accounts, attackers can use automated credential stuffing tools to try that same combination across banking, email, and shopping sites. Because so many services rely on email-based password resets, one exposed login can quickly open the door to broader account takeover, financial fraud, or identity theft.

How a Combolist Like This Comes Together

Combolists are assembled by pulling email and password pairs from older breaches, phishing sites, and malware infections, then merging everything into a single file, sometimes with a plain, unremarkable name like this one. Once uploaded to a Telegram channel, a combolist of this size can be downloaded and redistributed by many users within a short period of time.

Check If You Are Affected

You do not need to guess whether you are part of this leak. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including combolists like this one, so you can quickly find out and change any passwords that need it.
