HEROIC Analysts Found the ‘Ok’ Combolist Circulating on Telegram

What HEROIC Analysts Found

While monitoring private Telegram channels for newly circulating credential files, HEROIC analysts came across a combolist uploaded on June 7, 2025, and labeled simply "Ok." Despite the plain name, the file contained 494 real records pairing email addresses with plaintext passwords and the website URLs those logins were tied to, another small but usable file quietly moving through the same channels analysts track daily.

Why This Is Dangerous

Because the passwords in the "Ok" file are unencrypted and matched directly to the site each one belongs to, anyone who finds this file the same way HEROIC analysts did can immediately begin testing those logins. No special skill or software is needed beyond a copy of the file itself.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated website URLs

Why This Matters

Even a modest file like this one is enough to power credential stuffing, where attackers automatically test stolen email and password pairs against other websites in search of reused logins. If you are one of the 494 people in this leak and you have reused that password elsewhere, that account is now at risk of takeover, which can lead to drained funds, hijacked email, or identity theft carried out in your name.

How Combolist Leaks Work

A combolist pairs a username or email with a password, usually written as "email:password" per line, and files like this are commonly assembled from older breaches, malware infections, and previous leaks rather than a single new hack. Analysts frequently find these files under vague, low-effort names like "Ok," since uploaders rarely bother branding small batches, which makes them easy to overlook even though the risk to the people inside is identical to any larger leak.
