10,593 Passwords From the 9online.fr Dump Just Surfaced on Telegram

In June 2026, HEROIC analysts found a combolist titled 9online.fr - 10.594 emails, uploaded to Telegram by an individual user. The file contained 10,593 records of email addresses paired with plaintext passwords and the URLs those logins were used on. Why is this dangerous? Because every password in the file is stored in plaintext, an attacker can use each of the 10,593 entries to log in immediately, without needing to crack or guess anything. Anyone using a 9online.fr address who has reused that same password elsewhere is exposed well beyond this one account. Here is what was exposed in the 9online.fr leak: email addresses, plaintext passwords, and associated URLs. Why this matters: Email accounts like these are often used to recover other logins, so a compromised 9online.fr inbox can become the starting point for an attacker to reset passwords on banking, shopping, and social media accounts. Stolen credentials like these rarely stay in one place. Attackers feed lists like this into automated tools that test each email and password pair against banking sites, email providers, and online retailers, a technique known as credential stuffing. When a password is reused, one exposed account can lead directly to account takeover, identity theft, or financial fraud on completely unrelated services. How the 9online.fr Combolist Was Compiled: This combolist appears to have been built specifically around 9online.fr email addresses, pulled from older breach data, phishing campaigns, or malware logs and filtered down to that one domain. Focusing on a single email provider makes the file easier for attackers to target with automated login attempts. Check If Your 9online.fr Address Was Exposed: You do not have to wait to find out if your information is part of a leak like this one. HEROIC's free breach scanner checks your email address against a database of more than 400 billion exposed records, including combolists and stealer logs like this one, and tells you immediately if your credentials have shown up in a known breach. If you find a match, change that password right away, and avoid reusing it anywhere else.
