Mix Fresh B4_Jx Log Zooms In: 759 Plaintext Passwords Found

In mid-May 2026, HEROIC analysts examined a stealer log dump called "Mix Fresh B4_Jx" uploaded to a Telegram channel by an anonymous user. Zooming in on the file's 759 records, tied to United States based accounts, one detail stands out immediately: every single password is stored in plaintext, sitting right next to the email address and login URL it belongs to.

Why This Is Dangerous

That one detail, plaintext storage, is what separates this leak from many others. There is no hash to crack, no encryption to break, and no delay between finding the file and using the credentials. Each of the 759 records can be read and used exactly as it was captured from the victim's browser, making the barrier to misuse essentially zero.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login sites

Why This Matters

Because the passwords sit in plain view rather than behind any protection, anyone who reused one of these 759 passwords on another account is exposed to credential stuffing the moment someone runs this list against other sites. Email accounts are especially high-value targets in this scenario, since gaining access to one often allows an attacker to reset passwords elsewhere and expand the breach into broader identity theft or financial fraud.

How Stealer Logs Work

Stealer logs come from infostealer malware, which infects a device through pirated downloads, cracked software, or malicious attachments, then quietly pulls saved usernames, passwords, and browsing URLs straight out of the browser. These logs are typically shared on Telegram channels or dark web forums exactly as this one was, and the plaintext format is standard for this type of malware, which is part of what makes stealer logs so immediately usable by criminals.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including this stealer log. Run a search today to see if your information appears here, and change any passwords that show up before someone else uses them.
