The Ok Combolist: 427 Email and Password Pairs Hit the Dark Web

HEROIC analysts found a combolist named Ok that a Telegram user uploaded on May 25, 2025. The file contains 427 records pairing email addresses with plaintext passwords, along with the URLs of the accounts each login was taken from.

Why the Ok Combolist Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who gets a copy can read the credentials immediately, with no cracking needed. Each record also includes the URL the login came from, so an attacker can tell exactly which site a password unlocks and try it there first before testing it anywhere else.

What Was Exposed in the Ok Leak

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

Why This Matters Even for a Small List

A list of 427 records is small compared to major breaches, but the risk to each person on it is the same. Attackers use lists like this for credential stuffing, running each email and password pair against the matching site and other popular services. If a password from this leak was reused anywhere else, that account is exposed too, which can lead to account takeover, identity theft, and financial fraud.

How a Combolist Like This Gets Made

A combolist is a compiled file of email or username and password pairs, usually gathered from older breaches, stealer logs, or leaked databases and packaged into one list. These files are often shared for free in Telegram channels before spreading to dark web forums, where attackers test the credentials against major websites to find logins that still work.

Check If You Are Affected

If you think your email or a password you use could be part of this leak, do not wait to find out. HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records, including combolists like this one, so you can see what has been exposed and update any reused passwords right away.
