About This Record
What information was affected in the Reseau.Site incident?
The leaked export comprises merchant profiles, ambassador accounts, and individual customer records across multiple tables (user.csv, client.csv, particulier.csv, and transaction history). Compromised data classes include:
- Contact Coordinates: Validated user primary email addresses and landline/mobile telephone numbers.
- Personal & Company Identifiers: First and last names of business owners and retail customers, birth dates, and genders.
- Physical Addresses: Billing and delivery street addresses, postal codes, and French municipalities/cities.
- Authentication Credentials: Password hashes stored using MD5 and bcrypt cryptographic algorithms.
- Financial & Transaction Metadata: Historical client orders, invoices, and purchase records.
How many accounts were affected?
Strict RFC 5322 ASCII canonical verification confirmed 67,119 unique valid email addresses across the database.
Technical analysis and security risks
The exposure of verified emails, mobile numbers, business roles, and historical orders creates substantial risks of targeted invoice fraud, impersonation attacks, and credential stuffing. Affected individuals and merchant administrators should:
- Change passwords on any platforms sharing identical credentials.
- Scrutinize unexpected billing or delivery correspondence claiming to represent Reseau.Site.
