Inside the Mix Fresh B4_Jx Combolist: How 810 Logins Leaked Online

810 Login Credentials Leaked in the Mix Fresh B4_Jx Combolist. On April 21, 2026, a Telegram user uploaded a combolist file called Mix Fresh B4_Jx. HEROIC's threat intelligence team identified and verified the listing on July 31, 2026, confirming it contains 810 records of email addresses, plaintext passwords, and associated URLs. Why This Is Dangerous. The passwords in this file are stored in plaintext, so anyone who downloads it can use them right away without cracking or guessing. Matched with the login URLs, an attacker knows exactly which account each password unlocks, making automated login attempts fast and effective. What Was Exposed: Email addresses. Plaintext passwords. Associated login URLs. Why This Matters. Even a small leak like this one can cause outsized damage if the same password was reused elsewhere. Attackers commonly take combolists like this and run them against banking apps, email providers, and online stores in bulk, a technique called credential stuffing that can lead to account takeover, identity theft, and financial fraud. How Combolists Work. A combolist is a simple text file that pairs usernames or emails with passwords, usually pulled together from older breaches, phishing kits, or malware infections and then shared or sold in bulk. Because building one takes little technical skill, combolists like Mix Fresh B4_Jx are common on Telegram and spread quickly once uploaded. Check If You Are Affected.
