How the ‘Ok’ Telegram Combolist Led to 879 Leaked Passwords

In September 2025, HEROIC analysts found a combolist file named Ok circulating on Telegram. The file contained 879 records pairing email addresses with plaintext passwords, along with the URLs those credentials were originally used on.

Why the Ok Combolist Is Dangerous

Files like this one usually start with credentials pulled from older breaches, phishing pages, or malware infected devices, then get sorted, cleaned up, and repackaged for distribution. Because the passwords in the Ok file are stored in plaintext, whoever downloads it can read each one directly and try it against the matching URL with no extra effort.

What Was Exposed in the Ok Leak

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters for the 879 People Affected

A combolist this size is easy for a criminal to run through automated tools that test each email and password pair against banking, email, and shopping sites. Anyone in the Ok file who reused their password on another account is now at risk of that account being taken over, drained, or used for identity theft.

How a Combolist Like Ok Gets Built and Uploaded

A combolist is a plain text file pairing usernames or emails with passwords, typically assembled from a mix of older leaks and malware logs, then given a short name, in this case simply Ok, before being posted to a Telegram channel for buyers or other criminals to grab. This kind of casual naming and quick distribution is common for smaller combolists, which move fast and often go unnoticed until they surface in a scan.
