Hackers targeting Foxconn's Mount Pleasant, Wisconsin plant exfiltrated roughly 8 terabytes of data in May 2026, according to ransomware group Nitrogen. More than 10 million files—spanning server‑processor designs, board layouts, and network topologies—were posted as proof. Review of the leaked sample shows no Apple schematics, suggesting the iPhone supply chain remains intact. The breach also included financial records from Foxconn's Texas hub.

Apple’s own defenses protect pre‑production designs, yet its ecosystem of assemblers has been repeatedly breached. A Chinese factory fell victim in December 2025, and Luxshare was compromised in January 2026. This pattern underscores how third‑party networks become soft targets, exposing confidential projects from AMD, Google and Intel despite Apple’s internal VPN safeguards. Such leaks give rivals insight into component roadmaps that could shift market dynamics.

The intrusion knocked out Wi‑Fi and core plant systems, forcing workers to log hours on paper and halting production for about a week. Analysts worry that leaked topology maps could aid future attacks on data‑center infrastructure, but with no Apple design files in the dump, the immediate threat to consumer products appears minimal. Foxconn reports normal output has resumed and no ransom was paid.
