Your Login Details May Be Exposed: Mix Fresh B4_Jx Leaked 585 Records

HEROIC analysts found a combolist titled "Mix Fresh B4_Jx" circulating on Telegram, dated 19-Apr-2026 and containing 585 records. The file paired email addresses with plaintext passwords and included associated URLs pointing to the sites the logins belong to.

Why This Is Dangerous

The passwords in this dump are not hashed or encrypted, they are stored as plain text. That means anyone who grabs the file can start using the credentials right away, no cracking tools or technical skill needed. A file this size is small enough for a single attacker to work through by hand or feed into a script within minutes.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Small combolists like this one are often the first step in larger credential stuffing campaigns. If any of these 585 people used the same password across multiple accounts, attackers can try that same email and password pair on banking sites, email providers, and social media until one works. A single successful login can lead to account takeover, financial fraud, or identity theft.

How This Combolist Was Assembled

Combolists like this one are typically stitched together from several sources, older breached databases, phishing pages, or infostealer malware logs, rather than coming from a single hacked company. Threat actors compile these credential pairs into a text file and share them through Telegram channels and forums, often labeling them "fresh" to signal the data has not been widely circulated or checked against other leaks yet.

Check If You Are Affected

The best way to know if your email address appears in this leak, or in any of the thousands of other breaches HEROIC tracks, is to run it through HEROIC's free breach scanner. It checks your information against a database of more than 400 billion exposed records in seconds. If you find a match, update that password everywhere else you have used it.
