Security Analysts Found 436 Mix Fresh B4_Jx Passwords Leaked

Security researchers monitoring Telegram channels flagged a third batch from the "Mix Fresh B4_Jx" combolist series on April 21, 2026, this one holding 436 sets of stolen credentials. Like the smaller uploads before it, the file pairs email addresses with plaintext passwords and the URLs where they were originally used, giving anyone who grabs it a ready-made list of accounts to try breaking into.

Why This Mix Fresh B4_Jx Batch Raises Concern

Analysts tracking these uploads note a pattern: whoever is behind the "Mix Fresh B4_Jx" label keeps releasing fresh combolists in waves, each with hundreds of new credential pairs. That steady drip suggests an ongoing source of compromised logins rather than a single one-time leak, which means more batches like this 436-record file could keep surfacing.

What Was Exposed in This Mix Fresh B4_Jx Batch

• Email addresses
• Plaintext passwords
• URLs linked to each account

Why This Matters

Even a mid-size batch of 436 credentials carries real weight, especially since the passwords are stored in plaintext with no encryption to slow an attacker down. If your login shows up here, someone could be trying it right now against your email, streaming, or shopping accounts, hoping you reused the same password somewhere valuable.

How Combolists Work

Rather than hacking one target directly, the people who build combolists collect leftover credentials from many smaller incidents, stealer infections, and old leaks, then sort them into a single organized file. Once assembled, the list gets passed around Telegram groups where other criminals run it through automated tools that test each login across dozens of websites in seconds.

Check If You Are Affected

With multiple Mix Fresh B4_Jx batches circulating, checking your exposure is worth doing now rather than later. HEROIC's free scanner searches over 400 billion breached records, including combolists like this one, so you can see immediately if your email and password are part of the leak.
