HEROIC Finds Mansory 15 Leak: 4,950 Emails and Passwords

Mansory 15 Stealer Log: 4,950 Records Found on Telegram

On 08-Dec-2025, HEROIC analysts came across a file called "mansory 15" being circulated by a Telegram user in a channel used to trade stolen login data. The file contained 4,950 records, each pairing an email address with a plaintext password and the URL of the site the credentials were taken from. While smaller than many stealer log dumps HEROIC tracks, every record represents a real account someone can log into right now.

Why This Stealer Log Is Dangerous

The danger with this kind of log is that it gives an attacker everything needed to log in immediately: the email, the password, and the exact site where that password works. There is no cracking or guessing involved, and because the passwords were stored in plaintext, there is no encryption to slow anyone down either. For the 4,950 people in this file, their accounts are one click away from being accessed by someone else.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters

Anyone in this file who has reused the same password elsewhere faces a real risk of credential stuffing, where the same email and password combination gets tried automatically on other popular sites, including email, banking, and social media accounts. Since the exact URL is attached to each record, an attacker does not even need to figure out where to try first, making account takeover faster than with a typical leaked password list.

How Stealer Logs Work

Stealer logs are generated by malware that infects a victim's computer, often through a malicious download or infected file, and then quietly collects saved browser logins, passwords, and the sites they belong to. The stolen information is compiled into a log file, like this one named "mansory 15," and shared or sold through Telegram channels and dark web forums where other criminals can pick it up and start using it.

Check If You Are Affected

Even a smaller leak like this one is worth checking against directly. HEROIC's free breach scanner searches your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can quickly confirm whether you were affected and change any exposed passwords.
