One Telegram Upload. 578 Records. The Mix Fresh B4_Jx Combolist Leaked

What HEROIC Analysts Found

In April 2026, HEROIC analysts identified a combolist file labeled "Mix Fresh B4_Jx," uploaded to a Telegram channel. The file contained 578 records pairing email addresses with plaintext passwords, along with the URLs of the sites those logins belong to.

Why This Is Dangerous

The word "fresh" in this file's name is a signal that the credentials are being marketed as recently working logins, not old leftovers from years ago. Paired with a plaintext password and the exact site URL, each record gives an attacker a login that is more likely to still be active.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each login to the site it belongs to

Why This Matters

A file marketed as "fresh" is meant to be more valuable to buyers because the logins are less likely to have already been changed. For the 578 people in this file, that means a higher chance their current password, not an outdated one, is what is circulating. Anyone who reuses that password elsewhere is at risk of credential stuffing across other accounts.

How Combolists Work

A combolist is a compiled file of email or username and password pairs, usually gathered from breaches, stealer logs, or leaked databases. Sellers often label a batch "fresh" or "mix" to describe how recent or varied the source material is, then run the credentials through checker tools to confirm which ones still grant access before sharing or selling the file.
