If You Reuse Passwords, the Mansory 4 Leak Should Worry You

If You Reuse Passwords, the Mansory 4 Leak Should Worry You

HEROIC analysts found another stealer log carrying the name "mansory 4" circulating on Telegram, this one dated 8 December 2025 and containing 5,274,011 records. Each entry pairs an email address with a plaintext password and the URL of the site where that login was captured, the signature of malware that lifts saved credentials straight from an infected computer.

Why This Is Dangerous

If you've ever reused a password across more than one account, this is exactly the kind of leak that puts you at risk. Because every password in this file is stored in plaintext, an attacker doesn't need to break any encryption, they can simply take the email and password as they appear and try logging in elsewhere.

What Was Exposed in This Mansory 4 Log

• 5,274,011 email addresses
• Plaintext passwords tied to each address
• URLs showing which sites and services each credential unlocked

Why This Matters

Over five million records is enough to fuel large-scale credential stuffing, where attackers automate login attempts across banking, email, and shopping sites using stolen pairs like these. If your email and password combination is in this log and you've used it anywhere else, that other account is now at risk too, along with anything protected by the same recovery email.

How This Mansory 4 Stealer Log Was Collected

Stealer malware works quietly in the background of an infected device, copying saved browser passwords, autofill entries, and the web addresses tied to each login before sending it all back to the attacker. Files like this "mansory 4" log are often the combined output of many infections, bundled together and passed around or sold in Telegram channels dedicated to stolen credentials.

Check If You Are Affected by This Leak

Don't wait to find out the hard way. Search your email address in HEROIC's free breach scanner, which checks against more than 400 billion leaked records, and if it turns up in this log or any other breach, change that password immediately, especially anywhere you've reused it.
