Your Login May Be Exposed. The DARK MIX Leak Hit 887 Accounts.

On 04-Aug-2026, a Telegram user shared a combolist named "DARK MIX uploaded by a Telegram User" containing 887 email/username and plaintext password pairs. HEROIC analysts reviewed the file, which is built for exactly one purpose: testing stolen credentials against as many websites as possible.

Why This Is Dangerous

There is nothing sophisticated about how a combolist gets used, and that is exactly what makes it dangerous. Criminals run each email/password pair against a long list of popular websites, counting on the fact that at least some of the 887 people on this list reused that same password somewhere important.

What Was Exposed

• Email addresses / usernames
• Plaintext passwords
• URLs associated with the accounts

Why This Matters

Lists like this one feed directly into automated credential stuffing attacks, where a single successful login can cascade into much bigger problems: unauthorized purchases, drained accounts, or a hijacked email address used to reset passwords on everything else tied to it.

How Combolists Work

Building a combolist usually means pulling credentials from several older, sometimes years-old breaches and merging them into a single email:password file. From there, cracking or checker tools automate the process of testing every pair against a wide net of websites, and the finished list, like this one, tends to circulate on Telegram and dark web forums well before it's put to use.

Check If You Are Affected

If you think your credentials could be part of this or a similar leak, use HEROIC's free breach scanner to check your email address against a database of more than 400 billion breached records. It takes seconds and can tell you whether it's time to change a password.
