Delko Listed by sinobi Ransomware Group

On December 5, 2025, French car repair network Delko appeared on the leak site of the sinobi ransomware group. The attackers claim to have exfiltrated internal files from the company, which operates local garages across France and stores customer data related to vehicle maintenance, bookings, and payments.

What's Publicly Reported from Reporting

Public reporting indicates that sinobi listed Delko on its dark-web leak portal, presenting samples of allegedly stolen documents. The exact number of people affected remains unknown, but Delko serves thousands of ordinary drivers who booked services, requested estimates, or had repairs completed. Available reporting describes the incident as a classic ransomware attack involving both encryption of systems and subsequent data exfiltration. No confirmed timeline of initial breach or exact volume of records has been released by the company or the attackers.

Why This Matters for You and Your Family

When a garage chain like Delko is breached, the files taken often contain names, addresses, phone numbers, email addresses, vehicle registration details, and payment information. These records can be used to impersonate you with insurers, file fraudulent claims, or open accounts in your name. For families, a single breach can expose everyone listed on a shared vehicle—spouses, teenage drivers, and sometimes even linked family members. Once your data leaves a trusted local business and lands on a ransomware site, it circulates quickly among criminals who specialize in identity theft and harassment.

The Doxxing and Identity-Chain Risks

Ransomware leaks rarely stop at one company. Criminals combine the Delko files with other breaches to build detailed profiles. An email from your car booking can be matched to a gaming username, a family address, or a child’s account. This creates an identity chain that leads to doxxing, targeted scams, or account takeovers. Credential leaks like this one frequently cascade into gaming platforms, where children’s accounts become entry points for further harassment or extortion. Public reporting shows these chains often move from everyday service providers to social media, then to direct personal attacks.

Sinobi Group’s Known Track Record

Public reporting attributes sinobi with emerging in 2024 as a ransomware operation that uses double-extortion tactics. The group typically gains initial access through phishing or exploited remote desktop tools, exfiltrates data before encrypting systems, then posts samples on its leak site with deadlines for payment. Notable prior victims include other small-to-medium European businesses. Their playbook follows a pattern of publishing proof-of-compromise files and threatening full data dumps if ransom demands are not met. Readers can follow independent trackers for updated activity on this group.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to remove what you can.
• Rotate any password you used at Delko or similar service providers, and enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your data is caught in hours, not months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same address and contact details.
• Let remediation specialists handle takedown requests across data brokers and exposed records while you focus on securing your own accounts.
