Tarnaise des Panneaux SAS Listed by 8Base Ransomware Group

On January 3, 2025, French manufacturer Tarnaise des Panneaux SAS appeared on the leak site of the ransomware group known as 8base. The company, which produces high-density wood fibre boards marketed as Hardboard or Isorel®, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose personal information may have been exposed remains unknown, any customers, suppliers, employees or business partners whose details were stored in those files could now be at risk.

What Public Reporting Shows

Public reporting indicates that 8base listed Tarnaise des Panneaux on its dark-web leak site on January 3, 2025. The data consists of internal files exfiltrated after the company was hit by a ransomware attack. No confirmed victim count has been published, and the precise types of records taken have not been detailed beyond the broad description of internal files. The company’s website describes its core product as boards made from natural wood fibres with no synthetic binder, a specialty that suggests the stolen files could contain supplier lists, customer orders, employee records or financial documents.

Why This Matters for You and Your Family

When a company you deal with loses control of its internal files, your personal information can end up in the hands of criminals. Even if you never bought Hardboard directly, your name, address, phone number, email or payment details may have been stored if you were a supplier, contractor, employee or even a logistics partner. Once that data leaves the company’s servers, it can be sold, posted for other attackers or used to target you and your family with phishing, identity theft or harassment. Credential leaks like this one often cascade into account takeovers that reach far beyond the original breach.

The Doxxing and Identity-Chain Implications

Exfiltrated internal files frequently contain spreadsheets that link names, addresses, phone numbers and email accounts. Attackers can combine this information with data from previous breaches to build a complete picture of your online and offline life. A single leaked work email can lead to your personal accounts, your children’s gaming usernames, and eventually your home address. This chain reaction is exactly how doxxing campaigns begin: one exposed record becomes dozens, then hundreds, of connected data points that make targeted harassment or fraud much easier.

8base’s Publicly Known Track Record

Public reporting attributes 8base with emerging in early 2022. The group has listed hundreds of victims, many of them small-to-medium businesses across manufacturing, technology and professional services. Its typical playbook involves gaining initial access through compromised credentials or vulnerable remote desktop services, exfiltrating data before encrypting systems, then demanding payment while threatening to publish the stolen files on its leak site. When victims do not pay, 8base posts samples and eventually the full dataset, a pattern seen repeatedly in its publicly documented operations.

What to do

• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and leak sites so you do not have to chase them yourself.
