Analysts Flag a Second Vuln_Joomla Combolist, This Time With 46 Logins

HEROIC analysts identified a second combolist named Vuln_Joomla, this one uploaded by a Telegram user on July 15, 2026. It is smaller than the earlier Vuln_Joomla file HEROIC tracked, containing 46 records, each pairing an email address with a plaintext password and the URL that login was used on. Why This Is Dangerous: Each of these 46 records is a complete, working login. The attacker does not need to guess or crack anything, the email, the exact plaintext password, and the site it unlocks are already paired together. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to each credential pair Why This Matters: The repeated appearance of Vuln_Joomla-named files suggests an ongoing pattern of small combolists being pulled from the same or similar sources over time. For the 46 people in this specific file, the risk is credential stuffing: if a password here was reused elsewhere, attackers can use it to attempt logins on banking, email, and shopping accounts, leading to account takeover or identity theft. How This Combolist Was Built: A combolist compiles stolen or leaked login pairs, often sourced from vulnerable Joomla-based websites or related breaches, then organizes them by the URL each credential works on. Multiple files sharing a similar name, like this Vuln_Joomla upload and its predecessor, often come from the same threat actor working through the same target list over several months.
