The X817 HQ H0TMAIL Combolist Holds 731 Hotmail Logins in One File

In July 2026, HEROIC analysts identified a combolist file labeled "X817 HQ H0TMAIL" uploaded to a Telegram channel. The file contained 731 exposed records tied to United States based accounts, including email addresses, plaintext passwords, and the URLs of the sites those login pairs unlock.

Why This Is Dangerous

The "HQ" label in this file's name suggests the credentials inside were curated or checked before being packaged, meaning attackers view them as higher quality and more likely to still work. Combined with plaintext passwords matched to specific login URLs, this file is ready to use the moment someone gets a copy.

What Was Exposed in the X817 HQ H0TMAIL Combolist

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

With 731 credential pairs concentrated in one file, an attacker has enough material to run a focused credential stuffing campaign. If any of these passwords were reused on other accounts, victims risk account takeover, identity theft, and financial fraud stemming from a single leaked email and password pair.

How a "HQ" Combolist Like This Gets Built

Combolists marked "HQ," short for high quality, are usually built the same way as other combolists, by pulling email and password pairs from older breaches, phishing pages, or stealer malware infections. The difference is that sellers or Telegram users often test the credentials first and filter out dead logins, leaving a smaller but more reliable file like this 731 record set before sharing it further.

Check If You Are Affected

A file labeled as high quality is exactly the kind of leak worth checking against. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can find out in seconds whether your credentials were part of this leak and change your passwords before anyone else gets there first.
