The Vuln_Plesk Combolist Leaked 236 Server Login Credentials Online

HEROIC analysts found a second combolist named Vuln_Plesk uploaded to Telegram on 27-Jun-2026, this time containing 236 records of email addresses, plaintext passwords, and URLs tied to Plesk server panels. Why This Is Dangerous: Plesk credentials control access to server and website management, so a leaked login here can hand an attacker far more power than a typical personal account, including the ability to modify or take down entire websites. What Was Exposed: - Email addresses or usernames - Plaintext passwords - URLs tied to each Plesk login Why This Matters: A small file of 236 records can still cause serious damage when the accounts involved manage web servers. If an attacker gains access to even one of these Plesk panels, they can deface sites, steal stored data, or use the server as a launching point for further attacks against its visitors. How a Combolist Like This Works: These credentials are typically gathered by scanning the internet for Plesk installations with known vulnerabilities or weak passwords, then harvesting whatever login details are exposed. The resulting list gets shared on Telegram, often labeled with the software name so buyers know exactly what type of access they are purchasing. Check If You Are Affected: If you run a Plesk server, check your login against HEROIC's free breach scanner, which searches more than 400 billion leaked records, to confirm whether your credentials were part of this leak.
