Reported Details of the Incident
Public reporting indicates the victim is a family-owned group whose history dates back to 1952, when Maurice Warsemann opened a garage in central France. Laurence Deletang-Warsemann, granddaughter of the founder, currently serves as CEO. The Qilin group claims to have exfiltrated internal files during a ransomware attack and has set a public deadline of 3 March 2025 for the full release of the stolen data. The exact number of people whose records are included remains unknown, but the company’s family-owned status suggests employee, customer, and supplier information could be exposed.
Available reporting describes the data as internal files rather than a structured database of customer records. No independent verification of the stolen material has been published beyond the group’s own statements on its leak site.
Why This Matters for You and Your Family
When a company that has handled your personal information is hit by ransomware, the consequences reach far beyond corporate embarrassment. Internal files often contain names, addresses, phone numbers, email accounts, dates of birth, and financial details that criminals can weaponize. For an ordinary family this can translate into sudden spikes in phishing calls, identity-theft attempts, or fraudulent loan applications opened in your name.
