What Hackers Can Do With the 665 Logins in ‘Mix.’ Leak

On 23 Apr 2026, HEROIC analysts identified a combolist named "Mix." uploaded to a Telegram channel, containing 665 records that pair email addresses with plaintext passwords and the login URLs each credential unlocks.

Why This Is Dangerous

With a file like "Mix.," an attacker does not need advanced skills or expensive tools. They only need a text editor and a login page. Because the 665 passwords inside are stored in plaintext, an attacker can copy each pair directly into the matching site and gain access in seconds, no cracking, guessing, or brute forcing required.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

An attacker holding a list like "Mix." can automate the process, running all 665 credential pairs against banking portals, shopping accounts, and social media logins in a matter of minutes using credential-stuffing software. Since so many people reuse passwords, one working login from this list often unlocks several other accounts belonging to the same person, leading to identity theft and financial fraud.

How Attackers Use a Combolist Like "Mix."

A combolist named "Mix." signals exactly what it is: a blended set of credentials pulled from several sources, old breaches, phishing pages, and malware-infected devices, combined into one file. Attackers load files like this into automated tools that try each pair against many websites at once, then keep whatever logins succeed. The mixed origin makes it hard for any single victim to know where their credentials first leaked from.

Check If You Are Affected

If your email address is one of the 665 inside "Mix.," an attacker may already have working access to one of your accounts. HEROIC's free breach scanner checks your email against more than 400 billion compromised records and tells you immediately if you were exposed.
