The Joomla Leak: 565 Email and Password Combos Exposed

On July 11, 2026, HEROIC analysts found a combolist labeled "joomla" uploaded to a Telegram channel. The file contained 565 records, each pairing an email address with a plaintext password and the URL the credentials were tied to, apparently gathered from Joomla-powered websites or accounts. Why This Is Dangerous: Joomla is a widely used content management system, so accounts tied to it can include site administrator logins as well as regular users. Because the passwords are stored in plaintext, anyone who downloads this file can immediately attempt to log in using the exact credentials listed. What Was Exposed: The file contains email addresses, plaintext passwords, and the URLs each login was tied to. Why This Matters: If any of these 565 accounts belong to a website administrator, a successful login could hand an attacker control over an entire website, not just a single account. For everyone else, the usual risk applies: password reuse means an attacker can try the same combination on banking, email, or shopping accounts elsewhere. How This Combolist Was Likely Built: Combolists tied to a specific platform, like this Joomla-focused file, are often built by combining data from breached websites running that platform, or by filtering a larger stealer log down to accounts associated with Joomla logins. Check If You're Affected: If you manage or use a Joomla-powered website, or reuse passwords across your accounts, HEROIC's free breach scanner searches more than 400 billion leaked records so you can see what's exposed and secure your accounts before someone else does.
