3,313 Hotmail Logins Exposed in the 3800 Combo List Leak

3,313. That is how many real Hotmail login records showed up inside a file called 3800 Hotmail combo after it was uploaded to Telegram in January 2026. The name suggested a bigger batch, but HEROIC's verification confirmed 3,313 working records, each with an email address and a plaintext password attached.

Why This Is Dangerous

Every one of those 3,313 records represents an actual person's Hotmail account, not a random guess or a test entry. Attackers don't need to work hard to use this kind of file, they can load it straight into automated login tools and start testing accounts within minutes of downloading it.

What Was Exposed

• 3,313 total records
• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

Because the passwords sit in plaintext, there is no extra step for an attacker to take. The credential is ready to use the second the file is opened, which makes this exact kind of combo list especially popular among people running automated account takeover attempts.

How Stealer Logs Work

Combo lists like this "3800 Hotmail combo" are usually built by pulling matching email and password pairs out of larger stealer log collections, filtering specifically for one email provider. It's a common tactic because Hotmail and Outlook accounts tend to be linked to a lot of other services, which raises the value of the list even though the total record count is small. This kind of targeted filtering has occured with plenty of other webmail-focused leaks too.

Check If You Are Affected

If you use a Hotmail address, take thirty seconds and check it against HEROIC's free breach scanner, wich searches more than 400 billion compromised records to definately tell you if you need to change your password today.
