3.5K Hotmail Combolist Leaks 3,376 Valid Login Credentials

On 6 August 2026, a combolist titled "3.5K Hotmail Combo list Full Valid" appeared on Telegram, containing 3,376 records of email addresses and plaintext passwords along with associated URLs. The "Full Valid" label indicates the uploader claims to have tested and confirmed these credentials work.

Why This Is Dangerous

Unlike older, stale leaks, a list marketed as "valid" means someone has already checked that these email and password combinations still log in successfully. That makes this file more immediately dangerous than an unverified dump, since attackers can act on it right away without wasting time on dead credentials.

What Was Exposed

The "3.5K Hotmail Combo list Full Valid" file contains:

• Email addresses (Hotmail-associated)
• Plaintext passwords
• Associated URLs

Why This Matters

Hotmail and other webmail accounts are often the master key to a person's digital life, since they're used to reset passwords on banking, shopping, and social media accounts. A verified-valid combolist targeting Hotmail users significantly raises the risk of account takeover, inbox monitoring, and follow-on identity theft for anyone in this file.

How This Combolist Was Built

To produce a "full valid" combolist, whoever compiled it typically runs a checker tool against each email and password pair to confirm the login still works before selling or distributing the file. This validation step is what separates a low-value recycled dump from a combolist that criminals consider worth paying for.

Check If You Are Affected

If you use a Hotmail or Outlook account, it's worth checking now. HEROIC's free breach scanner searches more than 400 billion leaked records, including this combolist, to tell you if your email has been exposed.
