Inside the ‘Ok’ Combolist: How 1,733 Passwords Ended Up on Telegram

HEROIC analysts identified a combolist uploaded to a Telegram channel on June 4, 2025, containing 1,733 records of email addresses paired with plaintext passwords and the URLs where those logins were used. Like many Telegram-sourced files, this one was compiled and shared by an anonymous user rather than tracing back to a single named company breach.

Why This Combolist Is Dangerous

The passwords in this file are stored in plaintext, so anyone who downloads it can read them directly alongside the matching email and login URL. There is no cracking or guessing involved. Whoever has this file already has working login information for 1,733 accounts.

What Was Exposed in This Combolist

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

Why This Matters for Reused Passwords

Most people use the same password, or a close variation, across multiple accounts. If your credentials are in this file and reused elsewhere, an attacker can attempt credential stuffing, automatically testing the same email and password across banking, email, and shopping sites until one works, opening the door to account takeover, identity theft, or financial fraud.

How a Combolist Like This Ends Up on Telegram

A combolist is a plain text file of email-and-password pairs, usually pulled from older breaches, phishing pages, or malware infections and merged into a single file for easy distribution. Telegram has become a popular platform for sharing these lists because channels are quick to create, hard to shut down completely, and reach a wide audience of buyers with minimal effort. This file appears to have been assembled and posted by an individual user rather than sourced from one identifiable company breach.

Check If Your Email Appears in This Leak

With 1,733 email and password pairs circulating since mid-2025, checking your exposure only takes a moment. 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 find out and change any reused passwords before someone else finds them first.
