On June 6, 2025, French human-resources firm Best Profil appeared on the leak site of the lynx ransomware group, with attackers claiming to have exfiltrated internal files after a ransomware attack on the company that has spent two decades specializing in temporary and permanent recruitment, training, and related services.

What Public Reporting Shows
Available reporting describes the listing on the lynx leak site as part of an active ransomware campaign. The company’s own public announcement, referenced in the leak page, states it unified its interim, recruitment, and training operations under the Best Profil brand after 20 years of separate activities. Public reporting indicates that internal files were taken; the exact number of people whose records were exposed remains unknown. No confirmed list of specific data types such as names, addresses, or payroll details has been published by the group or the victim at the time of writing.
Why This Matters for You and Your Family
When a company that handles employment records suffers a breach, the information it holds often includes full names, dates of birth, national identification numbers, home addresses, phone numbers, email accounts, salary details, and banking information for both current and former employees as well as candidates. Best Profil works across temporary contracts, permanent placements, and training programs, so anyone who has used their services in the past two decades could be affected. If your data is among the stolen files, it can be sold quietly on underground forums long before any public announcement, giving thieves months or years to open accounts, file fraudulent tax returns, or target your family members whose details are linked through the same employer records.
The Doxxing and Identity-Chain Implications
Credential leaks from HR and recruitment databases rarely stay isolated. A single exposed work email or phone number can be correlated with gaming accounts, social-media handles, and family-member profiles to build a complete identity chain. Public reporting on similar incidents shows that once attackers link an adult’s employment data to a child’s gaming username or school email, the entire household becomes easier to dox. Gaming accounts are especially vulnerable because children and teenagers often reuse passwords or security questions derived from family information. Credential leaks like this one therefore cascade into account takeovers that expose chat logs, location data, and photos, feeding further extortion or identity theft.
