One Telegram Upload. 1,457 Records. The Ok Combo Leak Explained.
HEROIC analysts identified a combolist labeled "Ok" that was uploaded to a Telegram channel on 7 August 2025. The file contains 1,457 records made up of email addresses, plaintext passwords, and the login URLs those credentials belong to.
Why This Is Dangerous
Even with a bare-bones label, this single Telegram upload delivers 1,457 working credential sets, each pairing a working email address with a plaintext password and the exact site it logs into. That is enough for an attacker to attempt logins immediately, with no cracking required.
What Was Exposed
- Email addresses
- Plaintext passwords
- Login URLs for the associated accounts
Why This Matters
Anyone whose email and password appear among these 1,457 records is at risk of account takeover, particularly if that password has been reused elsewhere. Attackers commonly run combolists like this one through automated tools that test each credential pair against email providers, banking sites, and social platforms, a tactic known as credential stuffing.
How Combolists Work
A combolist pairs usernames or email addresses with passwords, one credential set per line, and is usually assembled by combining data from older leaks and stealer logs rather than a single company's breach. Combolists like this one, however plainly labeled, get uploaded to Telegram channels where other users download them and test the credentials against real login pages.
Check If You Are Affected
To find out whether your email address or passwords appear in this combolist or any other leak, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records in just a few seconds.
