Someone Has Your Hotmail Password: 3,344 Credentials Leaked

HEROIC's monitoring systems flagged a Telegram-distributed stealer log labeled "3,500 HOTMAIL" in October 2024. The file contains 3,344 compromised Hotmail credentials with passwords in plaintext, meaning anyone who accesses this data can immediately attempt to log in to affected accounts without any technical expertise.

Plaintext Passwords: No Barrier Between Attackers and Your Account

The 3,344 passwords in this Hotmail dump are completely unprotected. They are stored in readable text, exactly as each user originally created them. An attacker does not need specialized tools or computing power—they simply read the password and enter it. This level of exposure means that from the moment this file was shared on Telegram, every credential in it became immediately exploitable.

What Was Exposed

• Email Addresses — Hotmail accounts that double as Microsoft account identifiers
• Plaintext Passwords — fully readable credentials with no encryption layer
• URLs — login pages where each email-password pair was originally captured by malware

One Compromised Password, Multiple Compromised Accounts

Attackers do not stop at your Hotmail inbox. They feed stolen credentials into automated credential stuffing software that tests each email-password combination against hundreds of other services—online banking, cloud storage, social networks, shopping platforms, and more. With 3,344 credential pairs available, these automated attacks can run around the clock. If your Hotmail password is shared with any other account, those accounts are now equally vulnerable.

The Infostealer Malware Behind This Leak

These credentials were not stolen from Microsoft's servers. They were extracted from individual users' computers by infostealer malware—programs that embed themselves in a device after a victim clicks a malicious link, opens an infected attachment, or installs compromised software. The malware silently copies every password stored in the browser's credential vault, then sends the data to attackers who compile it into themed dumps like this Hotmail collection. The victim usually has no idea their device was compromised until their accounts start showing unauthorized activity.

Check If Your Credentials Were Exposed

Do not wait for suspicious login notifications to find out your password was leaked. Search your email address now using HEROIC's breach scanner, which covers more than 400 billion compromised records. You will find out in seconds whether your Hotmail credentials are part of this 3,344-record dump or any other breach in HEROIC's database, giving you the chance to change your password and activate two-factor authentication immediately.
