487,690 Passwords From the 500K Mix Geo Combolist Leaked Online

HEROIC analysts identified a new combolist circulating on Telegram in late July 2026, labeled by its uploader as "500k Mix Geo CombolistJul29 3." The file contains 487,690 individual records pairing email addresses with plaintext passwords, along with the website URLs those credentials belong to.

Why the 500K Mix Geo Combolist Is Dangerous

What makes this leak especially risky is that the passwords were stored and shared in plaintext, meaning there is no encryption standing between an attacker and a usable login. Anyone who downloads this file can immediately try each email and password pair against major websites, no cracking or decryption required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts the credentials belong to

Why This Matters

Combolists like this one are built for one purpose: credential stuffing. Attackers feed the email, password, and URL combinations into automated tools that test the same login on banking sites, email providers, and social media accounts. If you have ever reused a password across more than one account, a single leaked pair can unlock several accounts at once, including ones that hold financial information or personal messages.

How a Combolist Like This Gets Built

A combolist is not a single hack. It is a compiled collection, often stitched together from older breaches, malware infections, and phishing pages, then organized into "combo" (combination) files that pair a username or email with a password. The "Mix Geo" label on this file suggests the uploader combined credentials from multiple countries and sources into one package before sharing it in a Telegram channel, where other criminals can pick it up and use it immediately.

Check If You Are Affected

With 487,690 credential pairs now in circulation, the safest move is to find out whether your own email address is part of this leak. 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 your exposure and update any reused passwords before someone else uses them first.
