Good_WHM Uploaded by a Telegram User: Plaintext Credentials Exposed

HEROIC analysts identified a combolist uploaded to Telegram in February 2026 under the name "Good_WHM." The file contained a set of email address and plaintext password credentials paired with associated login URLs. While the exposure is limited in size, the data itself is sensitive: it includes the raw password value needed to log directly into an account, not just a username.

Why This Is Dangerous

Because the password in this leak is stored as plaintext rather than hashed or encrypted, anyone who downloads the file can read the credential exactly as it was typed by the account owner. Paired with the login URL, an attacker has everything needed to attempt an immediate sign in, no cracking or guessing required.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

Why This Matters

Even a single exposed credential pair can lead to real harm if the password is reused elsewhere. Attackers routinely take small leaks like this one and test the same email and password combination against banking sites, email providers, and social media platforms, a technique known as credential stuffing. If the affected account holder reused this password anywhere else, those accounts are now at risk of takeover.

How Combolists Work

A combolist is a simple text file that pairs usernames or emails with passwords, usually one pair per line. Threat actors build combolists by pulling credentials from older breaches, phishing pages, or malware infections, then repackage and share them on Telegram channels and dark web forums. Combolists are attractive to attackers because they are easy to automate: a script can attempt to log in with thousands of pairs in minutes, checking which ones still work.

Check If You Are Affected

You don't have to wonder whether your email and password are sitting in a file like this one. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists, stealer logs, and database dumps, so you can find out in seconds if your credentials have been exposed and take action before someone else does.
