Mansory 4 Stealer Log Holds Exactly 2,620,774 Login Pairs

The Mansory 4 Stealer Log Exposes 2,620,774 Login Pairs

HEROIC analysts reviewed a stealer log labeled "mansory 4" that surfaced in a Telegram channel, dated 11 March 2026. The file contains 2,620,774 records combining email addresses, plaintext passwords, and the URLs of the sites those credentials were entered on, a pattern typical of malware that pulls saved login data straight from a compromised device.

Why This Is Dangerous

Every one of the 2,620,774 passwords in this log is stored in plaintext, meaning there's no encryption standing between an attacker and a working login. Anyone who obtains this file can immediately attempt to sign into the accounts it lists, and the paired URLs make it easy for attackers to know exactly which site or service each credential unlocks.

What Was Exposed in the Mansory 4 Log

• 2,620,774 email addresses
• Plaintext passwords tied to each email address
• URLs showing where each credential was used

Why This Matters

A log of this size gives attackers a large, ready-to-use list for credential stuffing, automatically trying each email and password pair against popular banking, email, and retail sites. Anyone whose information appears here who has reused a password elsewhere is at meaningful risk of account takeover, financial fraud, or identity theft.

How the Mansory 4 Stealer Log Was Likely Built

Stealer logs like this one come from infostealer malware that infects a device, then quietly collects everything saved in the browser: usernames, passwords, autofill fields, and the web addresses tied to each login. The malware sends this data back to whoever controls it, and the resulting file is often packaged with a distinctive name, like "mansory 4," before being shared or resold on Telegram.
