The “Ok” Combolist Exposed 434 US Accounts on Telegram

HEROIC analysts identified a combolist labeled "Ok" uploaded by a Telegram user in July 2025. The file contains 434 records pairing email addresses with plaintext passwords, along with associated URLs, and is tagged as United States data. Small in scale, this file still represents 434 real people whose login credentials are now sitting in a downloadable file on Telegram.

Why It Matters That This Data Is US-Focused

Combolists organized around a specific country tend to be used against services popular in that region, from US banks to major retail and email platforms. If your email and password are among these 434 US records, an attacker has a credential that is likely to work on services you actually use day to day, since the list was compiled with that regional targeting in mind.

What Was Exposed in This "Ok" File

• Email addresses
• Plaintext passwords
• Associated URLs linking each credential to a login page

Why This Matters Even at 434 Records

A combolist this size is still enough for an attacker to run through automated credential stuffing tools, testing each email and password combination against banks, email providers, and shopping sites. If you are one of the 434 people in this file and have reused your password elsewhere, you are at real risk of account takeover, identity theft, and financial fraud.

How a Regional Combolist Like This Gets Built

A combolist is a compiled file of email and password pairs, often gathered from phishing pages, malware, or older breaches. Some lists, like this one, are filtered or tagged by country to make them more useful for attackers targeting a specific region's users and the websites they are most likely to use, then shared or sold on Telegram under short names like "Ok."
