See If Your Hotmail Login Is in the B4_Jx Leak of 294 Accounts

In April 2026, a Telegram user uploaded a combolist called Hotmail Fresh B4_Jx, this time containing 294 records of email addresses, plaintext passwords, and associated URLs, all belonging to Hotmail account holders in the United States. It is worth taking a minute to check whether your own login is one of the 294 sitting in this file.

Why the Hotmail Fresh B4_Jx Combolist Is Dangerous

A Hotmail inbox often doubles as the recovery point for other accounts, so a leaked login here can open the door to password resets on banking apps, shopping sites, and social media. Because the passwords in this combolist were stored in plaintext, there is nothing standing between the file and someone trying your credentials right now.

What Was Exposed in Hotmail Fresh B4_Jx

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

It only takes one working password for an attacker to get into an inbox, and from there, into everything connected to it. Whether you are one of 294 people in this specific leak or one of millions across other breaches, checking your exposure takes less time than reading this article and can save you from a much bigger headache down the road.

How Combolists Work

A combolist gathers usernames or emails and their matching passwords from a mix of older breaches, phishing sites, and malware, then compiles them into one downloadable file. These lists circulate quickly on Telegram, where anyone can grab a copy for free or a small fee, and once a login appears in one list, it often reappears in others as criminals trade and recombine their data.

Check If You Are Affected
