Mansory 8 Stealer Log: 725,092 Plaintext Passwords Exposed

In March 2026, a Telegram user uploaded a stealer log dataset labeled "Mansory 8" to a public channel. The file contains 725,092 records pulled straight from malware-infected computers, including email addresses, plaintext passwords, and the URLs of the accounts those passwords unlock. HEROIC's threat intelligence team has verified the data as authentic and added it to our breach database, which now tracks details from more than 400 billion exposed records worldwide.

Why This Stealer Log Leak Is Dangerous

A stealer log is different from a typical corporate data breach. Instead of hackers breaking into a company's servers, this data comes directly from malware that was secretly running on victims' own computers. Info-stealing malware quietly copies every saved password, browser cookie, and autofill entry it can find, then bundles it into a file like this one for sale or free distribution on Telegram. Because the passwords in the Mansory 8 file are stored in plaintext, anyone who downloads it can read your login credentials instantly, with no cracking or decryption required.

What Was Exposed in the Mansory 8 Dump

• Email addresses
• Plaintext passwords
• URLs showing exactly which site or service each password unlocks

Pairing a URL with its matching email and password means an attacker doesn't have to guess where an account lives. They can go straight to the login page and try the stolen credentials immediately.

Why This Matters for You

If you reused any of these credentials elsewhere, you're at risk of credential stuffing, where automated tools test the same email and password combination across hundreds of other websites. A successful match can lead to account takeover on email, banking, or shopping accounts, opening the door to identity theft and financial fraud. Because the malware was likely present on the device for some time before the log was uploaded, other saved information on that machine may also be compromised.

How Stealer Logs End Up Online

Info-stealing malware typically arrives through a malicious download, a cracked software installer, a phishing email attachment, or a fake browser update. Once installed, it scans the victim's browser and system for saved passwords, session cookies, and autofill data, then quietly sends everything back to the attacker. These collected files, known as stealer logs, are then packaged and shared or sold on Telegram channels and dark web marketplaces, often within days of infection.
