If You Reuse Passwords, 106,445 Leaked Logins Should Worry You

HEROIC analysts identified a stealer log dataset, tracked as MAIL ACCESS 108590 ALL COUNTRY VALID 100, that a Telegram user uploaded on 11-Nov-2025. The file contains 106,445 records pulled from infected devices across multiple countries, including email addresses, plaintext passwords, and the login page URLs tied to those accounts, all marked as confirmed working logins.

Why This Is Dangerous

If you reuse the same password across more than one account, files like this one are exactly what puts you at risk. Each of the 106,445 records already pairs a working email address with a plaintext password and the exact site it opens, so an attacker does not need to guess, they only need to try that same password somewhere else.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

With 106,445 confirmed working logins spanning multiple countries, this file gives attackers a large, verified list to run through credential stuffing tools. If a password from this leak is reused elsewhere, it can lead to account takeover, and in more serious cases identity theft or financial fraud.

How Stealer Logs Work

Stealer log malware infects a device, often through a fake download, cracked software, or a malicious attachment, and quietly copies saved browser passwords, autofill data, and session details. Sellers then test the stolen logins and label batches "valid" once confirmed, sometimes combining credentials from many countries into one large "all country" file before sharing it through Telegram.

Check If You Are Affected
