The ‘Ok’ Combolist Quietly Resurfaced: 874 US Logins Exposed

In May 2025, HEROIC analysts quietly identified another combolist titled 'Ok' uploaded by a Telegram user, separate from a similar file bearing the same name. This version contained 874 records pairing email addresses with plaintext passwords, along with the URLs those accounts belonged to, tied primarily to users in the United States.

Why This Ok Combolist Is Dangerous

Because the passwords in this file are plaintext, they can be used immediately without any cracking. The matching URLs make the file more dangerous still, since attackers know exactly which site each login belongs to and can attempt to sign in right away rather than guessing.

What This Ok Leak Exposed

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

Why This Matters

A leak of 874 records may seem small, but each one represents a working login that could be reused elsewhere. Because so many people rely on the same password across multiple accounts, this kind of leak feeds directly into credential stuffing attacks, account takeover, and eventually identity theft or financial fraud.

How Combolists Like Ok Are Assembled

A combolist is a compiled file of email or username and password pairs, usually drawn from older breaches, malware infections, or manual collection, then packaged and shared quietly on Telegram channels or dark web forums. The fact that HEROIC has now tracked more than one Ok combolist suggests the same source may be releasing batches of stolen credentials over time.

Check If You Are Affected

If you had an account active around May 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.
