The Mix Fresh B4_Jx Dump: 5,070 Stolen Logins Hit the Dark Web

In April 2026, HEROIC analysts found a combolist labeled Mix Fresh B4_Jx uploaded by a user on Telegram. The file contained 5,070 records made up of email addresses, plaintext passwords, and URLs tied to the accounts. Why This Is Dangerous: this combolist gives an attacker a ready-made set of working email and password pairs. Because the passwords are stored in plaintext, there is no encryption standing in the way, so the credentials can be used to attempt logins right away. What Was Exposed: the file includes email addresses used to sign into accounts, plaintext passwords tied to each address, and URLs showing where the credentials were used. Why This Matters: 5,070 records is a modest but real number of people. Anyone who reused one of these passwords on another account faces credential stuffing attacks, where attackers automatically try the same email and password combination across other sites, which can lead to account takeover, identity theft, or financial fraud. How a Combolist Like This Gets Made: combolists like this one are typically assembled by pulling matching email and password pairs from older data breaches, phishing pages, or malware-infected devices, then labeling and packaging them, often with a name like Mix Fresh to signal the data was recently compiled, before sharing or selling them through Telegram channels. Check If You Are Affected: if you want to know whether your email address appears in the Mix Fresh B4_Jx combolist or any other leak, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records, so you can find out quickly and change any passwords that need it.
