Is Your Hotmail Password in This 6,600-Record UHQ Combo Leak?
In December 2024, HEROIC analysts identified a combolist labeled UHQ Hotmail combo, uploaded to Telegram by a user tracked as hqhotmailcomboowner. The file contains 6,600 records pairing email addresses with plaintext passwords, along with the URLs those credentials unlock.
Why a "UHQ Hotmail Combo" Should Concern You
The "UHQ" label means the person who assembled this list believes the credentials inside are still working, and every password is stored in plaintext rather than encrypted. That combination means an attacker with this file can try your email and password against Hotmail, or any linked account, the moment they open it.
What Was Exposed
- Email addresses
- Plaintext passwords
- URLs linked to the accounts
Why One Hotmail Password Can Put More Than Email at Risk
Most people use their Hotmail account to receive password reset links for banking, shopping, and social media. If your login is in this file and you have reused that password anywhere else, attackers can run it through automated credential stuffing tools against dozens of other services. That single point of exposure can turn into account takeover, identity theft, or financial fraud far outside your inbox.
How a Combo List Like This One Gets Made
A combo list, or combolist, is built by gathering matching emails and passwords from smaller leaks, phishing pages, or infected devices, then merging them into a single file. Lists focused on one provider, like Hotmail, are common because buyers on Telegram and dark web forums often want credentials tied to a specific service. Once uploaded, a file like this can be downloaded and reused by many different attackers.
