The nb041 Leak: 3,112 Passwords Exposed. Yours Might Be One.

HEROIC analysts found a stealer log file named "nb041" uploaded to a Telegram channel on December 16, 2024. The file contains 3,112 records taken directly from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts and API endpoints those credentials unlock.

Why This Is Dangerous

There is no encryption or obfuscation standing between an attacker and these passwords. They are stored in plaintext, matched directly to the correct email address and login page, and ready to use the moment someone opens the file. That means the accounts affected by this leak could be accessed right now, without the account holder ever knowing something went wrong.

What Was Exposed in the nb041 Leak

• Email addresses
• Plaintext passwords
• URLs of the associated login pages or API endpoints

Why This Matters

A leaked email and password pair is the exact fuel attackers use for credential stuffing, automatically testing the same login across other sites to find where else it works. If you reused this password anywhere, that account is at risk too, and the fallout can range from account takeover to identity theft and financial fraud.

How This Stealer Log Was Created

Stealer malware infects a device and quietly copies saved passwords, browser autofill data, and active login sessions before sending everything back to whoever controls the malware. Because it comes straight from the victim's own computer or phone, the passwords are captured in plaintext exactly as they were typed or saved. Files like "nb041" are then shared or sold through Telegram channels, which is exactly where HEROIC analysts found this one.
