Mix Fresh B4_Jx Telegram Leak Hands Hackers 75 Live Logins

Mix Fresh B4_Jx: A Small Telegram Stealer Log With 75 Live Logins

On April 4, 2026, HEROIC analysts flagged a stealer log file named "Mix Fresh B4_Jx" after it was uploaded by a Telegram user to a channel where stolen credentials are traded. The file is small compared to major corporate breaches, containing 75 records, but each one pairs an email address with a plaintext password and the exact URL where that login was used. For the 75 people affected, the risk is just as real as it would be in a much larger leak.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, there is nothing standing between an attacker and a working login. Anyone who downloads the file can immediately try each email and password combination on the site it was captured from. There is no cracking, no guessing, and no delay. The included URLs even tell an attacker exactly where to point each set of credentials.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites where each login was entered

Why This Matters

A small leak can still cause serious damage to the people in it. If any of the 75 passwords in this file were reused on other accounts, such as banking or email, attackers can use credential stuffing to break into those accounts too. Account takeover is the most immediate risk here, since the stolen logins are already matched to the exact site each one unlocks.

How This Kind of Stealer Log Gets Made

Stealer logs like Mix Fresh B4_Jx come from malware infections on ordinary computers. Once installed, the malware reads passwords saved in the browser and records anything typed into a login screen, then bundles that information together with the site's URL. The result is packaged into a file and shared or sold on Telegram channels, where anyone can grab a copy. These files are usually smaller batches, gathered from a handful of infected machines rather than a single hacked company database, which is why record counts like this one tend to be modest.

Check If You Are Affected

If you think a device you use may have been compromised, don't wait to find out the hard way. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can see right away if your credentials have been exposed. Run a free scan, and update any password that shows up as compromised.
