If You Reuse Passwords, the Hotmail 6 Leak Should Worry You

HEROIC's threat detection systems identified a stealer log file called Hotmail 6 being shared on Telegram. This is part of a numbered series of Hotmail-targeted credential dumps, and it contains 2,123 records. Each entry links a Hotmail email address to a plaintext password along with the URL of the service where the credential was harvested by malware. The data represents real accounts belonging to real people whose devices were compromised.

Your Password Is Fully Readable

All 2,123 passwords in this file appear in plaintext. If your Hotmail account is in this dump, your password is visible to anyone who downloads the file. There is no cryptographic protection — no hash to crack, no cipher to break. The password appears exactly as you typed it, and it can be used to log into your account within seconds of being found.

What Was Exposed

• Email Addresses — Hotmail accounts that may be linked to Microsoft services and used for account recovery
• Plaintext Passwords — your actual password, stored in fully readable format
• URLs — the login pages and web services where your credentials were intercepted

Why Password Reusers Should Be Concerned

This breach is especially dangerous if you use the same password for your Hotmail account and other services. Attackers know that most people reuse passwords, so they systematically test every stolen credential against popular platforms — online banking, Amazon, Netflix, work email, and social media. Your Hotmail password might be the same one protecting your financial accounts. A single match gives attackers a foothold that can expand to your entire digital identity.

Where This Data Came From

Hotmail 6 is a stealer log produced by infostealer malware. This type of malware infects devices through deceptive downloads, email attachments, and malicious ads. It silently copies every password stored in your web browser — including passwords you saved years ago and forgot about. The malware also captures cookies and session tokens, which can grant access to accounts even without the password. All of this stolen data is compiled into numbered log files like Hotmail 6 and traded among cybercriminals.

Check If Your Credentials Were Exposed

The Hotmail 6 stealer log is now indexed in HEROIC's breach database, which contains over 400 billion compromised records. Use HEROIC's free breach scanner to check if your email address or password was included. If you find your credentials in this dump, change your Hotmail password immediately, update any other accounts that share the same password, and turn on two-factor authentication everywhere possible.
