Mansory 10 Data From 2025 Surfaces: 2.6M Records Leaked

mansory 10 Stealer Log: 2,662,678 Records From December 2025 Surface

HEROIC analysts catalogued a large stealer log dataset labeled "mansory 10" circulating on Telegram. The data itself is dated December 1, 2025, meaning it sat on infected devices or in criminal hands for months before HEROIC's analysts found it recently making the rounds. The file contains 2,662,678 records of stolen login data, including email addresses, plaintext passwords, and the URLs of the websites those credentials unlock.

Why the mansory 10 Leak Is Dangerous

A gap between when data is stolen and when it resurfaces doesn't make it safer, it often makes it more dangerous, since victims have had no reason to change passwords they don't know are exposed. With 2,662,678 plaintext credential pairs already matched to their exact login URLs, this is one of the largest single stealer logs HEROIC has catalogued, and every entry is ready for immediate use.

What Was Exposed

• Email addresses
• Plaintext passwords, stored and shared with no encryption
• URLs of the login pages tied to each stolen credential

Why This Matters

At this scale, automated credential stuffing tools can work through millions of login attempts, quietly succeeding wherever a password still matches. Because this data has likely been circulating since late 2025, anyone who hasn't changed a reused password since then remains exposed to account takeover, identity theft, and financial fraud right now, not just at the time of the original theft.

How Stealer Logs Work

Stealer logs come from infostealer malware, families such as RedLine, Raccoon, or Vidar, that infects a device through a cracked download, malicious ad, or phishing link, then quietly copies whatever is saved in the browser: usernames, passwords, cookies, and autofill data. That data is bundled into a "log" and often resold or reshared multiple times before it becomes widely known, exactly the pattern behind this batch, which HEROIC's analysts found on Telegram.

Check If You Are Affected

Given the size and age of this file, checking your exposure is worth doing even if you think an old password is long forgotten. HEROIC's free breach scanner checks your email against more than 400 billion leaked records collected from breaches, stealer logs, and dark web dumps, and shows you exactly what to change if something turns up.
