9,925 Passwords Exposed in freesurf.fr Stealer Log Leak

In June 2026, HEROIC analysts found a stealer log tied to freesurf.fr uploaded to Telegram by a threat actor. The file contained 9,925 records made up of email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This freesurf.fr Stealer Log Is Dangerous

The scale of this leak, nearly 10,000 records, makes it a large target for automated attacks. Because the passwords are stored in plaintext and matched to the exact login URL, there is nothing for an attacker to figure out. They can load the list into automated tools and start testing every email, password, and URL combination in minutes.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

With 9,925 ready-to-use logins in hand, attackers can attempt account takeover across all of the accounts represented in this log. If any of these passwords were reused on other sites, such as email, banking, or shopping accounts, credential stuffing tools let attackers try the same password across many unrelated services at scale, multiplying the damage from a single stealer log.

How Stealer Logs Work

Stealer logs come from malware that infects a device and silently copies saved browser passwords, autofill data, and the URLs tied to them, then sends everything back to the attacker. Because the theft happens on the victim's own computer rather than a hacked company server, the stolen credentials are often still valid and unchanged when the log surfaces on Telegram or dark web forums.
