Foxconn has confirmed a cyberattack on several of its U.S. factories, after the Nitrogen ransomware group claimed to have stolen confidential Apple project files. The attackers say they made off with 8TB of data spanning more than 11 million files, including material allegedly tied to Intel, Google, Dell, and Nvidia.

Foxconn acknowledged the intrusion but declined to say whether any customer data was actually taken. A spokesperson said the company's cybersecurity team activated response measures to keep production running, and that all affected factories are resuming normal operations. Apple famously takes the secrecy of unreleased products extremely seriously, and suppliers typically receive only the technical information needed for their specific manufacturing role.

Nitrogen is believed to be an offshoot of leaked Russia-based Conti 2 ransomware code. Researchers warned in February that a bug in the group's ESXi encryptor makes file recovery impossible, even for victims who pay up. This isn't Foxconn's first encounter with ransomware—the manufacturer was previously hit by LockBit in 2022 and 2024.
