The Good_Plesk Dump Contains Exactly 2 Plaintext Server Admin Email and Password Pairs

HEROIC analysts identified the Good_Plesk stealer log dataset in October 2025, uploaded to Telegram by an anonymous threat actor. The dataset contained exactly 2 records, each pairing an email address with a plaintext password and the URL of a Plesk web hosting control panel. While the record count is minimal, Plesk administrator credentials represent access to entire web hosting environments, making even a single compromised record a significant security event for the affected server and all websites hosted on it.

Why 2 Plesk Credentials Are More Dangerous Than Thousands of Consumer Logins

Plesk is a web hosting control panel used by server administrators to manage websites, email accounts, databases, and DNS configurations. An attacker with valid Plesk credentials does not just compromise one account. They gain access to every website, application, and database hosted on that server, along with the ability to deploy malware, intercept email traffic, modify DNS records, and create backdoor accounts. Two working Plesk logins in a stealer log can represent complete control over dozens of websites and the personal data of all their users.

Data Exposed in the Good_Plesk Stealer Log

• Email addresses (used as Plesk administrator login identifiers)
• Plaintext passwords (full administrator credentials requiring no cracking)
• URLs (direct links to the Plesk control panel endpoints for each compromised server)

How Attackers Exploit Compromised Plesk Server Credentials

• Credential stuffing: Plesk admin emails tested across other hosting panels and cloud management platforms
• Account takeover: Full server administrator access enables installing malware, defacing sites, and exfiltrating databases
• Identity theft: Access to hosted email accounts and customer databases exposes thousands of end users indirectly
• Financial fraud: Redirecting payment pages, harvesting form data, and inserting skimming scripts across hosted websites

What Plesk Is and Why Server Admin Credentials End Up in Stealer Logs

Plesk is one of the most widely deployed web hosting control panels globally, used by web agencies, small businesses, and managed hosting providers. Server administrators often access Plesk through browsers on their everyday work computers, and those computers are frequent targets for info-stealing malware. When a device running Chrome or Edge with saved Plesk credentials becomes infected, the malware captures those credentials exactly as it would capture a social media password. The difference is the access level: a stolen Facebook password compromises one personal account, while a stolen Plesk password can compromise an entire hosting infrastructure and every website and database running on it. Small collections like Good_Plesk are sometimes leaked as freebies in Telegram channels to estabblish credibility before selling largerr batches.

Check If Your Server Credentials Appeared in the Good_Plesk Dataset

HEROIC's free breach scanner indexes over 400 billion compromised records, including targeted server credential logs like Good_Plesk. Enter your administrator email address to find out if your hosting panel credentials were exposed, and take immediate steps to rotate your Plesk passwords and audit all hosted sites for signs of unauthorized access.
