4,415,724 Logins for autosur.fr Surface in Dark Web Combolist

HEROIC analysts found a large dark web combolist listing 4,415,724 logins tied to autosur.fr accounts, uploaded to Telegram on 23 August 2026. Each record combines an email address with a plaintext password and the URL the login was tied to. This is a compiled list of credentials associated with the site, not confirmation that autosur.fr's own systems were compromised, but with more than four million entries, it is one of the largest files of its kind HEROIC has reviewed recently. Scanning your email only takes a minute and will tell you if you need to act.

What a Combolist of This Size Enables

At more than four million records, this file is built for automated, large scale abuse rather than targeting any one person. Attackers run tools that work through the entire list, attempting logins on the original site and testing the same password against unrelated services, all without human intervention.

The Login Data Exposed in the autosur.fr Combolist

• Email Addresses
• Plaintext Password
• URLs

The Risk at This Scale

Even a small success rate against a list this size translates into a large number of compromised accounts. Anyone included faces the chance of their autosur.fr login being used without permission, and if that password has been reused, the exposure can extend to email, banking or other online accounts.

How Combolists Reach Millions of Records

Combolists this large are usually assembled by merging multiple smaller breaches, phishing campaigns and infostealer logs tied to users of one service, then cleaning and deduplicating the data so each line is a usable credential. Once compiled, these files move quickly through Telegram channels and dark web marketplaces.

Check Now Before Anyone Else Uses Your Login

Scan your email to see whether it is part of this autosur.fr combolist or any other dataset HEROIC tracks. If you find a match, change that password right away, especially anywhere else you have reused it, and enable two-factor authentication. Check both personal and work email, since one compromised password can affect either.
