Inside a Combolist Leak: 68 Email and Password Records From Mix

The Mix combolist file matches 68 email addresses directly to plaintext passwords, and to the exact web addresses those logins belong to. That is one of the most dangerous pairings a leak can hand an attacker: a working username, a readable password, and the door to use it on. The file surfaced in August 2026 and was flagged by HEROIC analysts as a Combolist, a list of already paired credentials rather than data pulled from one hacked service. The only way to know if you're affected is to scan your email.

Why a Password Paired With a URL Is Worse Than a Password Alone

A password by itself is only half the problem. When it comes bundled with the exact site it unlocks, an attacker skips the guesswork entirely and goes straight to the login page. There is no need to test the credential against a dozen different services first.

That efficiency is what makes combolist files valuable to criminals even when the record count is small. Sixty eight working logins, tied to their exact destinations, can be run through automated tools in minutes.

What the Mix File Contains

• Email Addresses, which identifies the real inbox and person behind each login, enabling direct targeting and phishing.
• Plaintext Password, which is readable and usable immediately, with no cracking required before an attacker can try it.
• URLs, which point to the exact site each credential unlocks, letting an attacker skip straight to the right login page.

What Happens After a Login Like This Gets Used

If the password in this file is reused anywhere else, an attacker can move from one account to several in quick succession, a technique known as credential stuffing. Access to the linked email inbox can also be used to reset passwords on other services, turning one exposed login into a much wider takeover.

From there, the consequences can include financial fraud, impersonation, or accounts being locked out entirely once someone else changes the password first.

How a Combolist Like This Gets Built

According to HEROIC analysts, combolists like Mix are usually assembled by pulling working email and password pairs from many smaller sources, checking which ones still log in, and tagging each with the site it belongs to. The result is bundled together and passed around on channels like Telegram, often broken into smaller files and reposted under different names.

Responding to the Mix Leak

Start by using the tool above to scan your email and see whether your address appears in this file or others like it. If it does, change the password on the site the URL points to right away, and update it anywhere else you used the same one. This applies whether the address is a personal inbox or one you use for work.
