Hotmail Fresh B4_Jx uploaded by a Telegram User: U.S. Password Leak

What HEROIC Analysts Found

HEROIC's dark web monitoring team identified a combolist titled "Hotmail Fresh B4_Jx uploaded by a Telegram User," dated to 2 April 2026. The file contains 77 records pairing email addresses with plaintext passwords, along with the URLs of the sites those credentials were used on. It was shared through a Telegram channel used to trade combolists, and the affected accounts are tracked to the United States.

Why This U.S. Focused Leak Is Dangerous

The file is labeled "fresh," a term combolist sellers use to signal that the credentials are recently harvested and have not yet been widely tested elsewhere. That makes them more valuable to an attacker than an older, already-circulated list, because there is a better chance the passwords still work.

Every password in this file is stored in plaintext, so it can be used immediately without any cracking. Paired with the URL each login came from, an attacker knows exactly where to try it first, and from there can attempt the same email and password combination on other accounts belonging to the same U.S.-based individual.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs associated with each set of login credentials

Why This Matters

A "fresh" combolist like this one is prime material for credential stuffing, where automated tools test stolen email and password pairs against other websites while the credentials are still likely to be valid. Anyone who reused this password on another account is at heightened risk of account takeover.

From there, the damage can spread into identity theft or financial fraud, particularly if a compromised email account is used to reset passwords on banking or shopping sites.

How Combolists Work

A combolist is a file of email-and-password pairs, typically gathered from older breaches or malware infections and then shared or sold on platforms like Telegram. Sellers often label a batch "fresh" to indicate it was recently compiled and has not yet been picked over, which is exactly the kind of framing attached to this 77-record file.

Check If You Are Affected

The only way to know for certain whether your email and password appear in this combolist is to check. HEROIC's free breach scanner searches more than 400 billion leaked records, including combolists like this one, to tell you whether your information has been exposed. If it has, change that password immediately and avoid reusing it anywhere else.
