30,628 Passwords Exposed in the 30k Corps UHQ Combo Leak

HEROIC Analysts Flag the 30k Corps UHQ Combo Leak

HEROIC's threat intelligence team identified a combolist file known as "30k Corps UHQ Combo" that surfaced on 24-Dec-2022. The file contains 30,628 individual records, each one pairing a login credential with the exact web address it was meant to unlock.

Why This Is Dangerous

Every record in the 30k Corps UHQ Combo pairs an email address with a plaintext password and a URL. That combination is exactly what automated attack tools need to log into an account without any guesswork. There is no encryption standing between an attacker and a working login, and no need to crack anything first.

What Was Exposed

• Email addresses tied to real user accounts
• Plaintext passwords, readable with no decryption required
• URLs showing exactly which site or service each credential unlocks

Why This Matters

Because the passwords in this combolist are stored in plaintext, they can be plugged directly into credential stuffing tools that test the same email and password pair against banks, email providers, shopping sites, and social media all at once. Anyone who has ever reused a password is at risk the moment it shows up in a list like this one. A single working match can lead to account takeover, financial fraud, or a stolen identity.

How the 30k Corps UHQ Combo Combolist Works

A combolist is not the result of one company getting hacked. It is a compiled collection, usually stitched together from older breaches and leaks, then organized into neat email and password pairs so criminals can use it more efficiently. The URLs field in this particular file tells attackers precisely where to try each credential, which speeds up automated login attempts and removes the trial and error that would otherwise slow them down.

Check If You Are Affected

HEROIC maintains a free breach scanner backed by a database of more than 400 billion leaked records, including combolists like this one. Search your email address to see if your credentials appear in the 30k Corps UHQ Combo or any other exposure, and take a moment to update any passwords you have reused across multiple accounts.
