1.8M Logins Exposed in the Mansory Stealer Log Data Breach

Over 1.8 million logins are now circulating after a stealer log named Mansory was uploaded to Telegram on November 5, 2025. HEROIC analysts confirmed the file contains 1,816,483 records made up of email addresses, plaintext passwords, and the login URLs tied to each account.

Why the Mansory Leak Is Dangerous

The scale here matters. Nearly two million sets of working credentials, stored in readable plaintext and matched to their exact login pages, gives attackers an enormous head start. There is no need to crack or guess anything, the file hands over the keys directly.

What Was Exposed in the Mansory Log

• Email addresses
• Plaintext passwords
• Login URLs tied to each credential pair

Why This Matters for Anyone Who Reuses Passwords

A log this large is a goldmine for credential stuffing, where automated tools rapidly test millions of email and password combinations against banks, email providers, and shopping sites. Reusing a password anywhere else means this one leak could trigger account takeover, identity theft, and financial fraud on services that were never actually breached themselves.

How a Stealer Log This Large Gets Built

Info-stealer malware spreads through pirated software, fake downloads, and malicious attachments, then quietly harvests saved browser passwords and autofill data from every infected device. When enough infections accumulate, the results are combined into a single massive log, like Mansory, and distributed on Telegram or dark web marketplaces for other criminals to explioit.
