1,123 US Hotmail Accounts Leaked by Telegram User: Check Now

HEROIC Analysts Uncover a Fresh Hotmail Combolist Leaked on Telegram

On December 15, 2024, HEROIC analysts identified a combolist uploaded by a Telegram user containing 1,123 records of email addresses paired with plaintext passwords, along with associated URLs. The file was circulated openly within a Telegram channel, meaning anyone with access could download and use the credentials immediately.

Why This Is Dangerous

Every line in this combolist pairs a working Hotmail address with its plaintext password. That combination is the single most valuable thing an attacker can have, because it removes the need to guess anything. Whoever downloads this file can log directly into a victim's inbox, reset passwords on linked accounts, and impersonate the victim in emails to contacts, coworkers, or financial institutions.

What Was Exposed

• Email addresses (Hotmail/Outlook accounts)
• Plaintext passwords
• Associated URLs

Why This Matters

Because the passwords were stored and leaked in plaintext, they can be used instantly and at scale. Attackers routinely feed combolists like this one into automated tools that test the same email and password pair across banking sites, shopping accounts, and social media platforms, a technique known as credential stuffing. If a victim reused this password anywhere else, that account is now at risk of takeover, identity theft, or direct financial fraud.

How Combolists Work

A combolist is simply a plain text file of email-and-password (or username-and-password) pairs, often compiled from older breaches, phishing campaigns, or malware infections and then repackaged for resale or free distribution. Unlike a raw database dump, a combolist is built specifically for one purpose: to be plugged into automated login tools. Its simplicity is what makes it so dangerous, no technical skill is required to use one, only a list of target websites.

Check If You Are Affected

If you have ever used a Hotmail or Outlook account, it is worth confirming whether your credentials appear in this leak or any other breach. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, giving you an instant answer and clear steps to secure your accounts before someone else uses your password first.
