The usaor.net Leak: 781 Passwords Exposed. Yours Might Be One.

In May 2026, HEROIC analysts identified a combolist file circulating on Telegram that exposed 781 records tied to usaor.net. The file was uploaded by a Telegram user on 25 May 2026 and pairs email addresses with plaintext passwords and the URLs those credentials were used on, giving anyone who obtains it a ready-made list of working logins.

Why This Combolist Leak Is Dangerous

Because the passwords in this file are stored in plaintext, there is no encryption standing between an attacker and a working account. Anyone who downloads this combolist can immediately try each email and password pair against the site named in the URL, with no cracking or technical skill required. A small list like this one is still a complete, ready-to-use target for criminals.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each credential to the site it was used on

Why This Matters

Combolist data feeds directly into credential stuffing attacks, where automated tools test the same email and password pair across banking, email, and shopping sites. Anyone who reused this password elsewhere is exposed to account takeover, identity theft, and financial fraud the moment their credentials appear in a leak like this one.

How This Combolist Was Built

A combolist is a text file pairing usernames or emails with passwords, usually gathered from earlier breaches, phishing pages, or malware-infected devices and then compiled into one file for sharing or sale on Telegram and dark web marketplaces. Because combolists blend data from many sources, the same credential pair can keep resurfacing in leak after leak long after its original exposure.

Check If You Are Affected

If you've ever used the email address tied to this leak, don't wait to find out the hard way. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, so you can see instantly whether your credentials are exposed and act before someone else does.
