500k Mix Geo CombolistJul29 2 uploaded by a Telegram User: Plaintext

A Half-Million-Record Geo-Targeted Combolist Hits Telegram

HEROIC analysts identified a combolist labeled "500k Mix Geo CombolistJul29 2" uploaded by a Telegram user on 28-Jul-2026. The file contains 498,512 records pairing email addresses with plaintext passwords, along with the URLs each credential set unlocks. The "geo" and "mix" labeling suggests the list was assembled from multiple regions and sources before being packaged together and shared.

Why Nearly 500,000 Plaintext Passwords Is a Serious Problem

Because every password in this file is stored in plaintext, there is no cracking or decryption step standing between an attacker and a working login. Paired with the URL for each account, this list lets an attacker automatically test hundreds of thousands of email and password combinations against real websites in minutes, at a scale far larger than the small leaks that circulate daily.

What Was Exposed in This Combolist

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

Why This Combolist Leak Matters for Your Security

A list of this size is built for automated credential stuffing, where attackers run software that tries each email and password pair against banking sites, email providers, and social platforms. If you have ever reused a password, a match in a list like this can lead directly to account takeover, and from there to identity theft or financial fraud using your own accounts.

How Large Combolists Like This Get Assembled

A combolist is a compiled file of email or username and password pairs, usually pulled together from several older breaches and combined into one list. The "mix" and "geo" naming on this file suggests it blends credentials from multiple regions or sources into a single package. Files like this are traded on Telegram channels and dark web forums, where buyers use them to run mass login attempts against popular websites.

Check If Your Email Was Exposed in This Breach

Use HEROIC's free breach scanner to check whether your email address appears in this combolist or in any of the other breaches inside HEROIC's database of more than 400 billion leaked records. If you find a match, change that password right away and make sure it is not reused anywhere else.
