The Good_Plesk Leak Put 66 Hosting Panel Logins on Telegram

HEROIC analysts found a small combolist named Good_Plesk uploaded to a Telegram channel on May 21, 2026. The file contains 66 records of email addresses paired with plaintext passwords and the login URLs they were used with, most pointing to Plesk web hosting control panels. Why This Is Dangerous: Plesk panels give administrators control over websites, email accounts, and server settings. A working login lets an attacker take over a hosting account entirely, redirect a website, read stored email, or plant malicious code on every site the panel manages. What Was Exposed: - Email addresses - Plaintext passwords - Login URLs, mostly pointing to Plesk hosting panels Why This Matters: This is a small file by breach standards, only 66 records, but small does not mean low risk. Anyone who reuses a hosting panel password on other accounts faces the same credential stuffing and account takeover risks as victims of much larger breaches. A single compromised hosting panel can also be used to attack every site and visitor connected to it. How a Combolist Like This Works: A combolist is a plain text file pairing usernames or emails with passwords, typically gathered from smaller scale phishing pages, misconfigured servers, or infected devices and then shared on Telegram. Files this size are often the output of a single scan or a single compromised server rather than a large scale hack, but the credentials inside are just as usable by criminals. Check If You Are Affected: If you manage a website or hosting account, it is worth checking whether your email address shows up in this leak or any other. HEROIC's free breach scanner checks your email against more than 400 billion leaked records so you can find out quickly and reset any reused passwords.
