Hotmail Users Targeted: 21,084 Logins in the 11012026 File

HEROIC analysts found a combolist dated 11012026, internally labeled Hotmail (11012026), containing 21,084 exposed records. The file pairs email addresses with plaintext passwords and the URLs those logins were collected against, assembled specifically around Hotmail style accounts. Scanning your email is the only way to know if you're in it.

21,084 Hotmail Style Logins, Ready to Test

This isn't proof that Hotmail itself was broken into, it's a list of email and password pairs built around that one email provider, gathered from earlier leaks elsewhere and grouped together. The grouping makes it easier for an attacker to run large batches of logins against Hotmail specifically, along with anywhere else those same passwords might work.

Since the passwords are stored in plaintext, there's no cracking delay between getting the file and trying the logins.

The Three Fields in This File

• Email Addresses: identifies the account and gives an attacker a target for phishing.
• Plaintext Password: readable on sight, so it's usable for a login attempt immediately.
• URLs: shows which login page or service each credential pair was gathered against.

What 21,084 Compromised Hotmail Logins Enable

A working Hotmail login often unlocks more than just email. Many people use that inbox to receive password reset links for banking, shopping, and social accounts, so whoever holds a valid pair can potentially chain their way into several other accounts from that single login.

Reused passwords widen the damage further, since the same credentials frequently work on unrelated sites the file never mentions.

How a Targeted Combolist Like This Gets Made

A combolist is built by collecting email and password pairs from older leaks and sorting them, in this case by email provider, into a single file aimed at a specific kind of target. No new hack produces the data, it's recycled credentials organized for more efficient reuse testing. Grouping by provider, like Hotmail here, just makes the automated testing that follows faster and more focused.

Is Your Hotmail Address in the 11012026 File?

Scan your email to see if it's listed in this file. If it is, change that password everywhere you've reused it, since the risk here comes from the same credentials working across multiple sites, not just one.

Check this for a work email address too if you use one, reused passwords put it at the same risk as a personal inbox.
