Inside the 7.3K Hotmail Combo List: How 7,033 Passwords Leaked

Inside the 7.3K Hotmail Combo List: 7,033 Accounts Just Leaked

HEROIC analysts identified a combolist named "7.3K Hotmail Combo list Full Valid" that surfaced on a Telegram channel on 1 August 2026, just days before this report. The file contains 7,033 records pairing Hotmail email addresses with plaintext passwords, along with associated URLs, and its "Full Valid" label signals that the uploader is marketing every entry as an active, working login.

Why This Is Dangerous

Because the passwords in this list are plaintext and advertised as verified, an attacker can log into these Hotmail accounts right away without cracking or guessing. Being so recently uploaded, the credentials are less likely to have been changed yet, giving attackers a short but valuable window to log in before victims notice anything is wrong.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

A verified, freshly leaked combolist is exactly the kind of file that fuels immediate credential stuffing attacks, where automated tools try each stolen email and password pair against other popular sites right after release. Anyone who reused their Hotmail password elsewhere faces a real risk of account takeover, financial fraud, or identity theft in the days following a leak like this.

How a Combolist Leak Works

A combolist is built by collecting email or username and password pairs from earlier breaches, phishing pages, or malware infections, then testing them to confirm they still work before packaging the "valid" results for sale or free distribution. Sellers often label lists as "full valid" or "fresh" to attract buyers looking for high success rates, and Telegram remains a go-to platform for this kind of trade because it is fast, low cost, and hard to police.

Check If You Are Affected

If you use a Hotmail or Outlook account, or if you have reused a password on multiple sites, it is worth checking whether your information appears in this leak right away. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to tell you instantly if your email has been exposed, so you can change any vulnerable passwords before someone else logs in first.
