The Hotmail Stealer Log Exposed 837 Email and Password Pairs

HEROIC Analysts Identify a Hotmail-Focused Stealer Log

In May 2026, HEROIC's threat intelligence team identified a stealer log shared on Telegram under the name "HOTMAIL." The file contained 837 records, each pairing a victim's email address with a plaintext password and the URL of the login page that credential unlocked. The uploader grouped this batch specifically around Hotmail and Outlook-style webmail logins.

Why a Webmail-Focused Log Is Especially Risky

Because every record in this file is tied to a webmail login, the risk goes beyond a single account. Email inboxes are used to verify identity and reset passwords for almost every other online service, so a working Hotmail credential gives an attacker a direct path into whatever else that inbox controls, including banking, shopping, and social media accounts that send password reset links there.

What Was Exposed in the Hotmail Stealer Log

• Email addresses tied to each victim's webmail account
• Plaintext passwords, stored without encryption
• URLs identifying the exact webmail login page each credential unlocks

Why This Matters Even at Only 837 Records

A file this size might look small next to larger leaks, but the risk per person is identical. If your Hotmail credentials are in this file and you've reused that password anywhere else, an attacker can use your inbox to trigger resets across other accounts, turning one small leak into a much bigger problem, including identity theft and financial fraud.

How Webmail Credentials End Up in a Stealer Log

Information-stealing malware infects a device through cracked software, malicious attachments, or phishing links, then quietly copies passwords saved in the browser along with the sites they belong to. Whoever collects the results then sorts the data by service, in this case pulling out everything tied to Hotmail and Outlook login pages, and packages it as its own file for distribution on Telegram.

Check If Your Hotmail Account Was Exposed

The only way to know for sure is to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this Hotmail-focused file, and tells you instantly if your email address is included. If it is, change your password immediately, avoid reusing it anywhere else, and turn on two-factor authentication on your email account right away.
