The Vuln_Virtualmin Leak Exposed 338 Server Admin Logins

HEROIC analysts found a combolist called Vuln_Virtualmin uploaded to a Telegram channel on July 15, 2026. The file contains 338 records of email addresses, plaintext passwords, and URLs pointing to Virtualmin server control panels. Why This Is Dangerous: Virtualmin is used to manage web servers, including hosted websites, email accounts, and databases. A working login gives an attacker administrative control over a server, which means they can access every website and email account it hosts, not just one account. What Was Exposed: - Email addresses - Plaintext passwords - Login URLs pointing to Virtualmin control panels Why This Matters: Because Virtualmin manages entire servers, a single compromised login here can affect far more than one person. An attacker who gets in can read or redirect email, deface hosted websites, or use the server to launch further attacks. If the server administrator reused that password anywhere else, the damage can spread to their personal accounts too. How a Combolist Like This Works: Attackers scan the internet for Virtualmin panels with weak or default credentials, or steal logins through phishing and malware, then compile the working ones into a plain text combolist like this one. These files are shared on Telegram because server access is valuable both for direct abuse and for resale to other criminals. Check If You Are Affected: If you manage a server or hosting account, checking your exposure only takes a few seconds. HEROIC's free breach scanner checks your email against more than 400 billion leaked records so you can catch a compromised login before it is used against you.
