HEROIC Researchers Link the Ok Combolist to 1,098 Stolen Login Pairs

HEROIC researchers linked a combolist named Ok to a Telegram upload dated June 13, 2025. The file contains 1,098 records pairing email addresses with plaintext passwords, along with the URLs of the accounts each login belongs to.

Why This Ok Combolist Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who obtains it can read the credentials immediately, with no cracking required. Each record also includes the URL the login was pulled from, telling an attacker exactly which site to try first before testing the same password elsewhere.

What Was Exposed in This Ok Leak

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

Why This Matters for Anyone Reusing Passwords

Researchers note that lists like this are built for credential stuffing, where attackers run each email and password pair against the matching site and any other service where the same password might be reused. Reusing a password tied to this leak puts those other accounts at risk too, opening the door to account takeover, identity theft, and financial fraud.

How a Combolist Like This Gets Assembled

A combolist is a compiled file of email or username and password pairs, typically drawn from older breaches, stealer logs, or leaked databases and packaged into a single list. Analysts frequently trace these lists back to free shares in Telegram channels before they spread to dark web forums, where attackers test the credentials against major websites.

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.
