Our Analysts Found the “Ok” Combolist Leaking 782 Logins on Telegram

HEROIC analysts found a small combolist labeled simply "Ok" circulating after being uploaded by a Telegram user in May 2025. The file contained 782 records pairing email addresses with plaintext passwords, along with associated URLs. It is a modest file by volume, but the label reflects a common pattern on Telegram, where sellers use short, forgettable names for combolists that still contain real, usable login credentials.

Why a File This Small Still Poses Real Risk

Every one of the 782 records in the "Ok" combolist pairs a real email address with a real password stored in plain, readable text. An attacker does not need to crack or decode anything. They can take a credential pair straight from this file and try it on the exact site referenced by the included URL. If that password has been reused anywhere else, the attacker can move on to email, banking, or social media accounts using the same login.

What Was Exposed in the "Ok" File

• Email addresses
• Plaintext passwords
• Associated URLs linking each credential to a login page

Why This Matters Even for 782 Records

Attackers do not judge combolists by size. A file like this one is easily fed into automated tools that test each email and password pair against major websites in a process known as credential stuffing. If your information is among these 782 records and you have reused that password elsewhere, you face real risk of account takeover, identity theft, and financial fraud, regardless of how small the original file looks.

How a Combolist Like "Ok" Gets Made

A combolist is a compiled file of email and password pairs, usually gathered from phishing pages, malware infections, or earlier breaches and merged together by whoever assembles the file. These files are then given a short name, sometimes as simple as "Ok," and shared or sold in Telegram groups where others use them to attempt logins across popular sites. The plaintext passwords mean no additional cracking is needed before the credentials can be used.
