44,527 Hotmail Logins, One File: Inside the 45K Combolist 05-22 Leak

One file, 44,527 working logins. HEROIC analysts identified a combolist titled "45K Hotmail Combolist 05-22," uploaded by a Telegram user on 23 May 2026. Despite the "45K" in its name, the verified file contains 44,527 records pairing Hotmail email addresses with plaintext passwords and the URLs those credentials unlock.

Why This Is Dangerous

At more than 44,000 records, this is a sizeable, focused batch of Hotmail credentials, all stored in plain text and ready to use. An attacker doesn't need to target Hotmail users one at a time, a file like this lets them attempt tens of thousands of logins automatically.

What Was Exposed in the 45K Hotmail Combolist Leak

• Hotmail email addresses
• Plaintext passwords
• URLs showing the login page tied to each credential

Why This Matters: Volume Makes Automated Attacks Easy

A list of this size is built for credential-stuffing tools that test thousands of email and password pairs against login pages automatically, with no manual effort required. Because Hotmail and Outlook accounts often serve as the recovery email for banking and shopping logins, a single compromised inbox from this file can lead to account takeover, identity theft, or financial fraud well beyond email itself.

How a 45K-Scale Combolist Gets Compiled

Files labeled by size and date, like "45K Hotmail Combolist 05-22," are usually built by filtering a much larger pool of breached or phished credentials down to a single email provider, then packaging the result with a date stamp for buyers tracking freshness. These lists typically originate from older breaches, phishing pages mimicking Microsoft logins, or malware-infected devices.

Check If You Are Affected

With over 44,000 Hotmail accounts involved, this is one of the larger leaks in this batch. HEROIC's free breach scanner checks your email address against more than 400 billion leaked records, so you can find out immediately whether your Hotmail credentials have been exposed.
