1 Login Leaked in Good_Plesk Combolist: Check If It’s Yours

In March 2026, HEROIC's threat intelligence team identified a small combolist named Good_Plesk circulating among Telegram users. Dated March 14, 2026, the file contains a single record pairing an email address with a plaintext password and the URL of the site that login belongs to.

Why the Good_Plesk Leak Is Dangerous

Even a single leaked credential pair is dangerous if it works. Because the password in this file is stored in plaintext, whoever has the file can try the email and password combination on other websites immediately, no cracking required. If the person behind that one login reused the same password anywhere else, an attacker can walk straight into that account.

What Was Exposed in the Good_Plesk Combolist

• Email address
• Plaintext password
• URL of the website or service the credential belongs to

Why This Combolist Matters

One record might sound insignificant, but combolists like this one are rarely traded in isolation. Files like Good_Plesk are often combined with dozens of other small combolists into larger credential-stuffing lists, and the same reused password can unlock email, shopping, or financial accounts if the victim relies on it elsewhere.

How a Combolist Like This Works

A combolist is simply a text file pairing usernames or emails with passwords, usually pulled together from older leaks, stealer logs, or previous credential-stuffing attempts. Telegram users and dark web traders package and share combolists, no matter the size, because automated tools can test thousands of them against major websites in minutes. Size does not determine risk: what matters is whether the password still works.

Check If You Are Affected

The only way to know for sure is to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including combolists and stealer logs pulled from Telegram and the dark web, to see if your email address has been exposed. If you find a match, change that password immediately and turn on multi-factor authentication wherever it is offered.
