133 Hotmail Plaintext Passwords Were Just Dumped on Telegram

In May 2026, HEROIC analysts discovered a stealer log file labeled "135 Log Hotmail" circulating on a Telegram channel. The dataset contains 133 compromised records, each linking a Hotmail email address to its plaintext password and the URL where the login was captured. The data was extracted from malware-infected devices and targets users in the United States.

Why Plaintext Hotmail Passwords Are a Direct Line to Your Inbox

Hotmail accounts, now part of the Microsoft ecosystem as Outlook.com, remain active email addresses for millions of users. When these passwords are stored in plaintext, attackers can immediately access the inbox, read private emails, and intercept password reset notifications from other services tied to that email address.

A compromised Hotmail inbox acts as a control center for the victim's online identity. Attackers can use it to reset passwords on banking websites, social media platforms, and subscription services. They can also send phishing emails from the compromised address to the victim's contacts, leveraging established trust to spread malware or solicit sensitive information.

What Was Exposed in the 135 Log Hotmail Dump

• Email Addresses — Hotmail accounts functioning as primary login and recovery identifiers
• Plaintext Passwords — Unencrypted credentials that work immediately without cracking
• URLs — Specific websites and services where each credential was recorded by malware

Why 133 Hotmail Credentials Demand Urgent Action

Each of these 133 records is a complete credential pair that can be used for immediate account access. Hotmail addresses that have been active for years often hold extensive email archives containing personal financial information, medical records, travel bookings, and confidential communications that attackers can exploit for identity theft.

Credential stuffing tools will test these Hotmail passwords against other popular services within minutes of the file being downloaded. Users who have ever used their Hotmail password on another website are particularly vulnerable, as the same credential will unlock multiple accounts across different platforms.

How Stealer Logs Siphon Hotmail Passwords From Browsers

The 133 records in this dataset were harvested by infostealer malware targeting browser-saved credentials. Hotmail users who allow their browser to remember their login details make those credentials available to any malware that gains access to the system's password store.

The malware arrives through phishing emails, compromised downloads, and malicious advertisements. It executes silently, scanning the browser's credential database and extracting every saved password. The stolen data is packaged into log files categorized by email provider and uploaded to Telegram channels for distribution.

Because the extraction happens locally on the victim's device, server-side security measures like rate limiting and IP-based blocking provide no protection. The malware captures credentials before they ever leave the computer, bypassing all network-level defenses.

Check If Your Hotmail Credentials Were Exposed

If you have a Hotmail or legacy Microsoft email account and have saved your password in a browser, your credentials may be part of this or similar stealer log releases. HEROIC offers a free breach scanner that checks your email against more than 400 billion compromised records.

Scan your Hotmail address with the HEROIC breach scanner to check your exposure. If your credentials appear in any known breach, change your Microsoft account password immediately, enable multi-factor authentication, and update every other service where you have used the same password.
