mansory 4 uploaded by a Telegram User Exposes 6,038 US Passwords

HEROIC analysts uncovered a stealer log labeled "mansory 4" being shared by a Telegram user. The file traces back to 26-Dec-2025 and contains 6,038 records tied to United States users, including email addresses, plaintext passwords, and the URLs of the accounts those passwords open.

Why This Mansory 4 Stealer Log Is Dangerous

What makes this file dangerous isn't just the password, it's that each password comes pre-matched with the exact website it unlocks. An attacker doesn't need to guess whether a stolen login works on email, banking, or shopping sites. They already know, and can go straight to that address and try the credentials immediately. For the 6,038 people in this file, that removes almost every obstacle standing between a stolen password and a compromised account.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

Because the passwords are stored in plaintext, they don't need to be cracked, they work exactly as they were typed. That makes this data immediately useful for credential stuffing, where attackers try each email and password pair against other popular sites. Anyone in this batch of 6,038 who reused their password elsewhere is exposed to account takeover on those other accounts too, not just the one named in this file.

How Stealer Logs Work

Stealer logs come from malware that infects a device and silently copies the usernames, passwords, and site addresses saved in the browser, then sends that information back to whoever controls the malware. Because one infected device can hold credentials for many unrelated accounts, a single stealer log often mixes together logins from completely different services. Files like this one are then packaged and passed around on platforms like Telegram, where they can be picked up by anyone looking for working credentials.

Check If You Are Affected

You don't have to wonder whether your information was part of this leak. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you right away if you were affected. If your details turn up, changing that password and enabling two-factor authentication takes only a few minutes and shuts the door before anyone can use it against you.
