One Telegram Upload, 63 Accounts: The Vuln_Joomla Combolist Exposed

HEROIC analysts identified a small combolist named Vuln_Joomla shared on Telegram on 29 June 2026. The file contains 63 records, each pairing an email address with a plaintext password and a related URL, likely tied to Joomla-based website logins. Why This Is Dangerous: A Joomla login often controls an entire website's back end. With passwords sitting in plaintext, an attacker can log directly into any of these 63 accounts and, depending on the permissions attached, take control of the site itself. What Was Exposed: - Email addresses - Plaintext passwords - URLs to the associated Joomla sites Why This Matters: Gaining access to a website's admin account lets an attacker plant malicious code, redirect visitors to scam pages, or steal any customer data stored on the site. For the 63 people in this file, a single reused password could hand over control of an entire website. How a Combolist Like This Works: This file appears to target credentials connected to Joomla installations specifically, meaning whoever compiled it filtered a broader pool of stolen logins down to just the ones matching this content management system, making it more valuable to buyers looking to compromise websites rather than personal accounts. Check If You Are Affected: Check your email address against more than 400 billion records in HEROIC's breach database with HEROIC's free breach scanner to see if your credentials appear in this or any other leak.
