The ‘Ok’ Combolist: 438 US Email and Password Pairs Leaked

In August 2025, HEROIC analysts identified yet another combolist titled 'Ok' uploaded by a Telegram user. This file contained 438 records pairing email addresses with plaintext passwords, along with the URLs each login was tied to, with accounts traced primarily to the United States.

Why This Ok Combolist Is Dangerous

The passwords in this file are stored in plaintext, meaning they can be used the moment someone downloads the list, with no cracking involved. Paired with the URL for each account, an attacker can go directly to the correct site and attempt to log in with the exact credentials found in the file.

What This Ok Leak Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each account

Why This Matters

A leak of 438 records is small in absolute terms, but each entry is a working login that may be reused elsewhere. Because password reuse is so common, one exposed credential set can lead to credential stuffing on other sites, account takeover, and ultimately identity theft or financial fraud.

How Combolists Like Ok Keep Appearing

A combolist is a compiled file of email or username and password pairs, typically gathered from older breaches, malware infections, or manual collection, then shared on Telegram channels or dark web forums. HEROIC has now tracked several separate combolists carrying the Ok name, suggesting an uploader who releases stolen credentials in recurring batches rather than a single large dump.

Check If You Are Affected

If you had an account active around August 2025, it is worth checking whether your credentials appear in this leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can find out quickly whether your password needs to change.
