Mansory 6 Stealer Log Leaks More Than 5.5 Million Logins

In January 2026, HEROIC analysts identified a stealer log file titled "mansory 6," uploaded to a Telegram channel by an unidentified user. The file contained 5,590,806 records, each made up of an email address, a plaintext password, and the URL tied to the login the credentials were used for, making it one of the larger stealer logs HEROIC has tracked in this series.

Why the Mansory 6 Stealer Log Is Dangerous

A file of this size means millions of individual credential pairs are now circulating outside the control of the people they belong to. Because the passwords were stored in plaintext, there is no need for an attacker to crack anything, the login information is ready to use the moment the file is downloaded.

What Was Exposed in the Mansory 6 Log

• Email addresses
• Plaintext passwords paired with each account
• URLs indicating where each credential set was captured

Why This Matters

At more than 5.5 million records, this log gives attackers enough volume to run credential stuffing attacks at a massive scale, automatically testing stolen logins against banking, email, and social media platforms. Anyone whose credentials appear in this file is at risk of account takeover if the password was reused elsewhere, which can lead directly to financial fraud or identity theft.

How Stealer Logs Work

Large stealer logs like this one are built up over time from malware infections on many individual computers, rather than a single breach of a company's servers. Info-stealing malware, often spread through cracked software or malicious downloads, quietly harvests saved browser credentials from each infected device and reports back to the attacker. As results accumulate, sellers compile them into large numbered batches, this being the sixth in its series, before distributing them through Telegram and other criminal channels.

Check If You Are Affected

Given the scale of this leak, checking your exposure is strongly recommended. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, to show you instantly whether your email address was affected.
