1.8 Million Credentials Leaked in Mansory 3 Stealer Log Dump

In December 2025, a stealer log file known as "Mansory 3" surfaced on Telegram, and it was massive. The file contained 1,797,910 records of email addresses, plaintext passwords, and the login URLs tied to each one, all pulled from devices infected with information-stealing malware.

Picture 1.8 Million Logins Sitting in One Telegram Channel

Imagine every password you have ever typed into a browser, sitting in a single text file next to your email address and the exact site it unlocks. Now multiply that by nearly two million people. That is what the Mansory 3 log represents: a sprawling collection of ready-to-use credentials, organized and searchable, sitting in the hands of anyone who downloaded it from the channel where it was posted.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Every record in this log was plaintext, so there was no encryption to slow anyone down. Whoever has the file can read the passwords directly.

Why This Matters

A leak of this size gives criminals enormous reach. They load lists like this one into automated credential stuffing tools that try each email and password pair across hundreds of popular websites in minutes. Anyone whose credentials repeat across accounts is exposed to account takeover, identity theft, and financial fraud, often before they ever notice something is wrong.

How a Log This Size Gets Built

Stealer malware infects a device, then quietly harvests every password saved in the browser along with the website it belongs to. The malware ships that data back to the attacker automatically. Logs like Mansory 3 grow this large when an attacker combines results from thousands of infected machines into one file before uploading it for others to use or sell.
