Dark Web Intel: Mix Fresh B4_Jx Combolist Leaks 557 Logins

Dark Web Intel: Inside the Mix Fresh B4_Jx Combolist

HEROIC analysts tracked a combolist titled "Mix Fresh B4_Jx" that was uploaded by a Telegram user on 18 April 2026. The file contains 557 records of email addresses and plaintext passwords, along with associated URLs, tied to accounts in the United States.

Why This Is Dangerous

Since the passwords in this list are stored in plaintext, an attacker can use them the moment they get the file, with no cracking required. That means anyone who obtains this combolist can immediately try logging into the affected accounts, and if the victim reused that password anywhere else, the damage spreads well beyond the original account.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

Fresh combolists like this one circulate quickly on Telegram and dark web forums, feeding credential stuffing attacks where bots test the same email and password pair across many different sites. This is how a single leaked password turns into account takeover, identity theft, or financial fraud on services that were never actually breached themselves.

How Combolists Work

A combolist pairs usernames or email addresses with matching passwords into one file, usually gathered from smaller leaks, malware infections, or phishing campaigns and merged together for resale. Sellers label lists as "fresh" to advertise that the credentials were recently harvested and are more likely to still be valid, which is exactly why even a relatively small 557-record combolist like this one attracts buyers.

Check If You Are Affected

If you want to know whether your information is part of this leak, HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records. It takes seconds to search, and if you are exposed, you can change your password right away before someone else uses it.
