The Mix Fresh B4_Jx: 3,824 Stolen Login Credentials Hit the Dark Web

HEROIC analysts identified this stealer log on 13-Apr-2026. The breach exposed 3,824 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as Mix Fresh B4_Jx uploaded by a Telegram User.

Why This Is Dangerous

With 3,824 records exposed, this is a large stealer log containing a wide mix of email credentials from multiple services. All passwords in this file are stored in plaintext, meaning they require no technical effort to use. The mix of email providers and website URLs gives attackers a broad selection of accounts to target across many different platforms.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (website addresses where credentials were captured)

Why This Matters

Large mixed stealer logs like this one are valuable to cybercriminals because they contain credentials from many different types of accounts. Attackers use this data to run automated credential stuffing attacks across major websites. Even if you do not recognize the specific log name, your email and password could appear in files like this one if your device was ever infected with malware. The risks include account takeover, unauthorized purchases, identity theft, and financial fraud.

How a Stealer Log Works

Stealer malware infects devices through methods such as fake software downloads, email attachments, or compromised websites. After installation, the malware silently collects login credentials from the browser's saved password store, running sessions, and application data. The harvested credentials, along with the URLs of the sites they belong to, are compiled into a log file. Attackers then upload these files to Telegram channels or dark web markets where they are downloaded and used by multiple parties.
