The “Ok” Combolist Quietly Exposed 890 Email and Password Records

HEROIC analysts identified a combolist labeled simply "Ok" that was uploaded to Telegram, tied to a leak originally dated July 17, 2025. Unlike breaches that make headlines, this file circulated quietly under an unremarkable name, yet it still contains 890 records pairing email addresses with plaintext passwords, along with the login URLs those credentials belong to.

Why This Is Dangerous

Every password in this file is stored in plaintext, meaning anyone who downloads it can read the exact credential an account holder typed in, no cracking tools required. Paired with the matching login URL, an attacker can go directly to the correct sign in page and attempt access immediately.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

Why This Matters

A vague file name like "Ok" is exactly the kind of thing that lets a leak spread under the radar for a long time before anyone notices. If any of the 890 people in this file reused their email and password on another account, whether a bank, another email provider, or a social media platform, an attacker can use this leak to attempt to log in there too, a tactic known as credential stuffing.

How Combolists Work

A combolist pairs an email or username with a password, usually collected from older breaches, phishing pages, or malware infections, then bundled together and shared on Telegram, often under generic or unlabeled names that make the files harder to trace back to their original source. Attackers load these lists into automated tools that test each pair against dozens of popular websites, checking which ones still work.

Check If You Are Affected

You shouldn't have to wonder whether your credentials are sitting in a quietly circulating file like this one. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can find out in seconds if you were exposed and change any reused passwords before someone else does.
