The X1544 HQ MIX Leak: 1,511 Passwords Exposed. Yours Might Be One.

HEROIC analysts identified a combolist called X1544 HQ MIX circulating after it was uploaded by a Telegram user on July 27, 2026. The file contains 1,511 records pairing email addresses with plaintext passwords, along with the URLs of the sites those credentials were originally used on.

Why the X1544 HQ MIX Leak Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who downloads it can read the credentials directly with no cracking or decoding required. Pairing each login with its source URL tells an attacker exactly which site a password unlocks, making it simple to plug stolen credentials straight into the matching login page.

What Was Exposed in the X1544 HQ MIX Combolist

• Email addresses
• Plaintext passwords
• URLs of the accounts the credentials belong to

Why This Matters for Anyone Reusing Passwords

Combolists like this one are built for credential stuffing: attackers feed the email, password, and URL combinations into automated tools that try each login on the matching site and any other service that might share the same password. If you reused this password anywhere else, that account is at risk too. From there, account takeover, identity theft, and financial fraud all become possible, especially if the compromised account is linked to email, banking, or shopping logins.

How a Combolist Like This Gets Made

A combolist is a compiled file of username or email and password pairs, often pulled together from smaller breaches, stealer logs, or leaked databases and repackaged into one list. Once assembled, these files are traded or dropped for free in Telegram channels and dark web forums, where other attackers pick them up and run them against popular websites to see which logins still work.

Check If You Are Affected

If you think your email or a password you use might be part of this leak, do not wait to find out the hard way. HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records, including combolists like X1544 HQ MIX, so you can see what has been exposed and update any reused passwords right away.
