The Hotmail Fresh B4_Jx Leak: 803 Passwords Exposed. Yours Might Be One.

HEROIC analysts identified a combolist labeled "Hotmail Fresh B4_Jx" that was uploaded to a Telegram channel on 21 April 2026. The file contains 803 records made up of email addresses, plaintext passwords, and the login URLs those credentials belong to.

Why This Is Dangerous

Marketed as "fresh," meaning recently harvested and not yet widely tested, this combolist is exactly the kind of file attackers move on quickly. Each record pairs a working email address with a plaintext password and the exact site it logs into, so there is nothing to crack, just a login to attempt.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs for the associated accounts

Why This Matters

Anyone whose email and password appear among these 803 records is at risk of account takeover, particularly if that password has been reused elsewhere. Because this list is advertised as fresh, attackers are more likely to act on it quickly, running the credentials through automated tools that test them against email providers, banking sites, and social platforms.

How Combolists Work

A combolist pairs usernames or email addresses with passwords, one credential set per line, and is usually built by combining data from older leaks and stealer logs rather than a single company's breach. "Fresh" combolists are advertised as newly assembled or recently verified, making them more attractive to buyers looking for accounts that have not yet had their passwords changed.

Check If You Are Affected

To find out whether your email address or passwords appear in this combolist or any other leak, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records in just a few seconds.
