9online.fr Email Users Hit: 13,628 Accounts and Passwords Leaked

HEROIC analysts found a combolist tied to 9online.fr that a Telegram user uploaded on June 10, 2026. The file contains 13,628 records pairing email addresses with plaintext passwords, along with the URLs those credentials unlock. Why This Is Dangerous for 9online.fr Users Because the passwords in this file are stored in plaintext, an attacker does not need to crack or decrypt anything before trying them. Paired with the account URLs included in the dump, this file gives criminals a direct, ready-to-use list of email logins they can attempt immediately, no extra work required. What Was Exposed Email addresses Plaintext passwords URLs linked to the accounts Why This Matters Email accounts are often the key that unlocks everything else. Anyone who can log into your inbox can reset passwords on your banking, shopping, and social media accounts, making this kind of leak especially dangerous. If any of the 13,628 people in this file reused their email password elsewhere, they are exposed to credential stuffing attacks that automatically test the same login across hundreds of other websites. How This Combolist Was Built and Shared A combolist is a compiled list of email or username and password pairs, usually pulled together from older breaches, phishing pages, or malware that steals saved logins. Once assembled, these files circulate on Telegram and dark web forums, often free or cheap, because they let low-skill attackers run large-scale login attempts without doing any of the original hacking themselves. Check If You Are Affected If you use a 9online.fr email account or think your credentials could be part of this leak, HEROIC's free breach scanner checks your email address against a database of more than 400 billion exposed records. Run a quick check, and if you find a match, update that password immediately on every account where you have reused it.
