Researchers Link Hotmail.com.br Logsfox to 38,740 Stolen Logins

HEROIC analysts uncovered a combolist called "hotmail.com.brlogsfox," uploaded by a Telegram user and dated August 28, 2025. The file contains 38,740 records pairing email addresses with plaintext passwords, along with the URLs of the sites those logins were originally used on.

Why the Hotmail.com.br Logsfox Dump Is Dangerous

The file's name points to Hotmail accounts, and because the passwords inside are stored in plaintext, anyone who gets hold of the list can log in immediately, no cracking needed. Email accounts like these are especially valuable to attackers because they are often used to receive password reset links for banking, shopping, and social media accounts, meaning one compromised inbox can unlock several others.

What Was Exposed in the Logsfox Dump

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters for the 38,740 Accounts Involved

If your email and password are among these 38,740 records, an attacker already has everything needed to log in and start testing that same password against your other accounts. Because so many people reuse passwords across email, banking, and social platforms, a single leaked credential pair like this can lead to credential stuffing, account takeover, and ultimately identity theft or financial fraud.

How This Combolist Was Assembled

A combolist compiles login credentials, usually gathered through malware infections, phishing pages, or previous breaches, into a single file formatted as email and password pairs. This one appears to focus specifically on Hotmail logins, which is common when attackers or resellers filter larger collections down into smaller lists organized by email provider, making them easier to sell or use for targeted attacks. Lists like this are traded on Telegram channels and dark web forums where credentials are tested and resold.

Check If You Are Affected

With 38,740 records already circulating, checking your exposure is a quick way to know where you stand. HEROIC's free breach scanner searches your email against a database of more than 400 billion leaked records, including lists like this Hotmail combolist, so you can find out if you are affected and secure your accounts before someone else does.
