3_fresh Hotmail 27k Combolist Lets Attackers Log Into 2,154 Accounts

HEROIC analysts found a combolist called 3_fresh Hotmail 27k circulating on Telegram in February 2026, holding 2,154 email and password pairs. Combolists like this are built specifically so attackers can try stolen logins on other sites. Scan your email to see if yours is one of them.

What a Combolist Lets an Attacker Do

A combolist is not malware and it is not one company's database, it is a working list of email and password pairs assembled for one purpose: testing those logins against as many other sites as possible to see which ones still work.

What the 3_fresh Hotmail 27k File Exposed

• Email Addresses: the login name half of each pair, ready to be tried elsewhere.
• Plaintext Password: stored as readable text, so no cracking is needed before it can be used.
• URLs: the web addresses each login was originally tied to, which tells an attacker where else to try it.

Why Reused Passwords Make This Worse

If you used this same email and password combination anywhere else, from a shopping account to email itself, that account is exposed the moment someone runs this list against it. A single successful match can snowball quickly: once an attacker is inside your email, they can use password reset links to take over other accounts one after another.

How a Combolist Like This Gets Built

Combolists are usually stitched together from smaller leaks and earlier breaches, then organized into a single file purely so attackers can automate login attempts across many sites at once, rather than targeting one company directly. Software built for exactly this purpose can run through thousands of attempts automatically, which is why a combolist this size can be tested in a short amount of time.

Change These Passwords Now

Scan your email to check your exposure. If you find a match, change that password everywhere it was reused, and give each account its own unique password going forward. This holds true whether the account is personal or tied to your work.
