These documents appears to be just PDF schematics and electrical specifications, not even the real files that can be opened by Cadence Orcad or Allegro, anybody making a minimum wage in Quanta's production line have access to some of those files. If you are patient it is quite trivial to accumulate those documents and the tactic quite lame.<p>As someone who has audited Quanta in my previous jobs, I am constantly being surprised that these documents are leaked so infrequently. A "Project" in Quanta start with the customer send in their schematics and mechanical drawings to the Quanta "R&D" engineers so they could redraw it to enable production in Quanta, aka EVT; then it is DVT for multi-sourcing of components and compatibility and EMC compliance, then it is PVT. Engineers usually transform the documents to PDF files and upload to the company's document center, production line operators will download those PDF files and copy it here and there, maybe even with a USB thumb drive to copy it to a production station running Windows 98 and Adobe Reader with no network access. The factories get so many projects that the leaked document maybe is for a product that already died in EVT.<p>It is also amazing to me that those PDF iPhone Schematics always leak to the 3rd party repairman after sometime it is announced, apparently there is an invisible food chain. But for this one, REvil is simply trying to brand themselves instead of the ransom.
