cpanel_success 1 Leak Quietly Exposes 1,285 Hosting Logins

In July 2026, HEROIC analysts identified a combolist titled cpanel_success 1, uploaded to Telegram by an anonymous user. The file contained 1,285 records, each pairing an email address with a plaintext password, with many entries also including a URL. The "success" label in the name indicates these credentials were tested and confirmed to work for logging into cPanel, the control panel used to manage web hosting accounts.

Why This Is Dangerous

This one is easy to overlook, but it deserves attention. cPanel accounts are not ordinary logins, they control entire websites, including file storage, email accounts, and databases. Because the passwords in this list are stored in plaintext and were labeled as verified successes, an attacker can log into 1,285 hosting accounts immediately, with the potential to deface websites, steal stored data, or plant malware on every site tied to that account.

What Was Exposed

Based on verified data from this listing, the following information was included:

• Email addresses
• Plaintext passwords
• URLs linked to the associated accounts

Why This Matters

A compromised hosting account is a quiet but serious problem, since it can go unnoticed for a long time while an attacker uses it as a foothold. Beyond the immediate risk to the hosting account itself, credential stuffing means these same email and password pairs may unlock other accounts if the password was reused, opening the door to account takeover, identity theft, and financial fraud well beyond the original website.

How Combolists Are Built

A combolist like cpanel_success 1 is built by taking email-and-password pairs, often gathered from earlier leaks or malware infections, and testing each one against a specific target, in this case cPanel hosting panels. Only the pairs that successfully logged in make it into the final "success" file, which is why lists like this one are considered especially valuable and dangerous, every credential in them has already been confirmed to work.
