The Hotmail Combo 1 Leak: 4,656 Passwords Exposed. Yours Might Be One.

On December 1, 2024, a Telegram user uploaded a combolist named "Hotmail Combo 1." HEROIC analysts confirmed the file contains 4,656 records, each combining a Hotmail email address, a plaintext password, and a source URL.

4,656 Plaintext Passwords. No Encryption. No Delay Needed.

There's no technical barrier standing between this data and misuse. Because the passwords are stored in plaintext, anyone who obtains this file can start testing logins immediately, no cracking tools or time investment required.

What Was Exposed in the Hotmail Combo 1 List

• Hotmail email addresses
• Plaintext passwords
• Source URLs tied to each credential

Why This Matters

If your password shows up in a plaintext leak like this one and you've reused it anywhere else, that other account is now exposed too. Credential stuffing attacks work precisely this way: attackers don't guess passwords, they reuse the ones people already exposed elsewhere. For the 4,656 people in this file, the clock started the moment it was uploaded.

How Combolists Like This Get Made and Sold

Combolists such as Hotmail Combo 1 are usually assembled from breach dumps, phishing kits, or malware-harvested credentials, then organized by email provider and distributed on Telegram, either free to attract buyers or sold outright. The "1" in the name suggests this is the first in a series from the same source.

Check If You Are Affected

Don't wait to find out the hard way. HEROIC's free breach scanner checks your email against more than 400 billion leaked records in seconds, so you'll know right away if your Hotmail credentials were part of this leak.
