291,781 Accounts Exposed: Australia Uploaded by a Telegram User

HEROIC analysts found a combolist file shared on Telegram in August 2026 containing 291,781 records tied to an entry labeled "Australia uploaded by a Telegram User." Each line pairs an email address with a plaintext password, and many records also list the URL of the site the login was originally used on.

Why This Is Dangerous

The passwords in this file sit in plaintext, meaning there is no encryption standing between an attacker and a usable login. Paired with the URLs included in the leak, a criminal can move straight to the exact site a credential belongs to instead of guessing, turning a static file into a working attack list within minutes of downloading it.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the original accounts

Why This Matters

Passwords are rarely used just once. When the same email and password combination unlocks a banking site, an email inbox, or a shopping account, attackers can chain those logins together through credential stuffing. What starts as one leaked password can quickly turn into a full account takeover, opening the door to identity theft and direct financial fraud.

How a Combolist Leak Works

A combolist is a plain text file of login pairs, typically formatted as email:password, that is often assembled from several smaller breaches and stealer logs before being uploaded to a channel like this one. Because the format is so simple, it takes almost no technical skill to use. Automated tools can feed a combolist straight into login pages across hundreds of sites at once, which is why these files spread so quickly once they surface.

Check If You Are Affected

You do not need to wonder whether your information is part of a leak like this one. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this, so you can find out in seconds and secure any account still using a reused password.
