A May 2026 cyberattack on Foxconn by ransomware group Nitrogen has compromised over 30 confidential Apple documents, including server schematics dating back to 2020. The stolen files reveal detailed designs for Apple's internal server infrastructure, including the Matterhorn project that utilized Intel's 32-core Ice Lake processors with 128GB RAM configurations.

The breach exposed genuine Apple documentation created by company engineers, detailing server rack specifications, mechanical properties, and component dimensions. While these Intel-based server designs likely predate Apple's Silicon transition, the leak still provides competitors valuable insights into Apple's data center architecture and manufacturing requirements.

Beyond Apple, Nitrogen stole documents from AMD, Google, Intel, Nvidia, and dozens of other tech suppliers, totaling approximately 11 million files across eight terabytes. The attack specifically targeted North American Foxconn facilities that handle server assembly, sparing iPhone and other consumer product manufacturing sites.

Though the compromised files lack Apple Silicon motherboard details, they still represent a significant security lapse for Apple's cloud infrastructure planning. The breach demonstrates how supply chain vulnerabilities can expose proprietary technology across multiple companies simultaneously.
