753,635 Plaintext Passwords Dumped in Orange.fr Leak

HEROIC's dark web surveillance detected a significant stealer log collection targeting orange.fr users being shared on Telegram. First appearing in February 2023, this dataset exposes 753,635 records stolen from malware-infected devices, containing email addresses, plaintext passwords, and the URLs of services where victims entered their credentials.

Why Plaintext Passwords Create an Urgent Threat

The 753,635 passwords in this orange.fr-focused dump are stored in plaintext with absolutely no encryption or hashing applied. Each credential is readable on sight, requiring no computational effort to exploit. For the hundreds of thousands of affected users, this means their login details are fully actionable the instant an attacker accesses the file—no cracking tools needed, no waiting period.

What Was Exposed

• Email Addresses — primarily orange.fr accounts used for telecom services and as login IDs across the web
• Plaintext Passwords — unencrypted, immediately usable credentials
• URLs — the websites and services where these login credentials were captured

Credential Stuffing: How Reused Passwords Multiply the Damage

With over 750,000 email-password combinations now exposed, attackers can launch large-scale credential stuffing campaigns. These automated attacks test each stolen pair against banking sites, online retailers, cloud services, and social networks. Because a significant percentage of users reuse their orange.fr password elsewhere, a single leak can cascade into unauthorized access across multiple platforms, leading to financial loss and identity compromise.

The Infostealer Pipeline Behind This Leak

This data was harvested by infostealer malware—programs like RedLine, Aurora, or Meta Stealer—that infect devices through fake downloads, malicious email attachments, or drive-by exploits on compromised websites. Once installed, the malware silently extracts saved login credentials from browsers, captures session tokens, and records autofill entries. All stolen data is packaged into log files organized by domain, then sold or freely shared through Telegram channels and dark web forums.

Check If Your Credentials Were Exposed

HEROIC operates one of the world's most extensive breach databases, indexing over 400 billion records from data breaches, stealer logs, and dark web leaks.
