- J Group claims to have stolen 11 GB of sensitive DCS data
- Cybernews examined file examples but could not confirm their authenticity
- DCS has not confirmed or denied the alleged violation of ransomware
A company building dimensional engineering software for giants such as Siemens and Samsung would have undergone a ransomware attack which has seen it lose many sensitive customer data.
A group of ransomware qualifying as a group J Group recently added dimensional control systems (DCS) to its data leak site.
JGROUP claims to have stolen 11 GB of company data, including sensitive internal documents such as owner’s architecture and documentation, configuration files for integration with CAE, HPC and PLM systems, metadata on the customer side defining business objects, user authorizations and audit trails, sensitive legal documents and internal procedures for supports, technical support and security.
How to stay safe
DCS is a company based in Michigan specializing in quality and dimensional software for manufacturing industries. Its flagship product, the 3DCC variation analyst, helps manufacturers to simulate and analyze the dimensional variation of assemblies before the start of production.
Its customers working in automotive, aerospace, electronics and medical devices, and include industry giants such as Boeing, Volkswagen, Siemens and Samsung.
To prove his statements, J Group has published a .txt file and a compressed folder with samples. Safety researchers of Cyberness Inlanded the samples, and although they have determined that the documents contain the names of the people and certain spending reports, they have not confirmed, nor denies the authenticity of the files.
Researchers also pointed out that cybercriminals recycled the stolen files during previous attacks, to try to monetize them again.
For the moment, DCS is silent. There is no official confirmation or denial of the attack. We have contacted the company and update the article if we hear. If these files were actually stolen, the implications could be serious and include the risk of intellectual property, the compromise of the supply chain, exposure to customer data, as well as legal and regulatory impacts or operational disturbances.
The violation could undermine the technical integrity of DCS, the confidence of customers and the regulatory position.
