What was taken

The GGSINC.com data repository contains 14,672 content files with 66.45 GB of known listed content. The material is closely associated with Tata Hitachi Construction Machinery Company Private Limited and its product, parts, engineering, service and technical-publication workflows. GGS/GGSINC appears throughout the transfer and publication workflow, while the machine programmes and much of the underlying engineering content are Tata Hitachi product data. Coverage spans engineering and publication exchanges associated with Tata Hitachi operations in Dharward and Kharagpur, together with GGS publication work, Programming Team outputs and Shiva Service Bulletin material. Product families include EX, NX, PNX, Shinrai, TMX, ZAXIS, ZX, ZW and TL machine programmes. Core content consists of CAD geometry, assembly models, bills of materials, per-assembly parts tables, technical illustrations, operator and workshop manuals, troubleshooting and operational-principle documents, engine manuals, parts catalogues, ECN packages, SOP updates, correction packages, saleable-status material and bulk part-number mappings. Inspected engineering drawings include Tata Hitachi proprietary ownership and transmission restrictions; the repository also contains Hitachi Construction Machinery platform material and supplier-origin documentation.
