mansory 3 uploaded by a Telegram User Exposes 2.7M Passwords

HEROIC analysts identified a stealer log labeled "mansory 3" circulating on Telegram. Dated 10-Mar-2026, the file contains 2,762,843 records tied to United States users, including email addresses, plaintext passwords, and the URLs of the accounts those passwords open.

Why This Mansory 3 Stealer Log Is Dangerous

Nearly 2.8 million records puts this leak firmly in bulk-abuse territory. At that scale, attackers don't review the file manually, they feed it straight into automated tools that test every email, password, and matching URL in sequence. Because each password is already paired with the exact site it opens, the software wastes no time guessing, it simply tries the login where it's known to belong.

What Was Exposed

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

Why This Matters

Plaintext passwords mean an attacker can use them exactly as they were typed, with no cracking needed. At nearly 2.8 million records, this file is well suited to credential stuffing, where the same email and password pairs are tried across banking, email, and shopping sites far beyond the one the login was taken from. Anyone in this batch who reused a password elsewhere is at real risk of account takeover on accounts unrelated to this specific leak.

How Stealer Logs Work

A stealer log is produced by malware that infects a device and quietly copies the usernames, passwords, and site addresses saved in the browser, sending everything back to whoever controls the malware. Because one infected device often holds logins for many unrelated services, a single stealer log can span a huge range of accounts across many different sites. Files like this one, once assembled, are shared or sold in bulk on platforms like Telegram, where they reach anyone looking for working credentials.

Check If You Are Affected

With 2.76 million records in this one file, checking your own exposure is worth the minute it takes. 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 immediately if you were caught up in it. If you were, changing that password and turning on two-factor authentication closes the door before it can be used against you.
