A massive data breach has occurred in China, with a hacker stealing over 10 petabytes of classified data from a state-owned supercomputer. The breach is believed to have happened at the National Supercomputing Center in Tianjin, which is home to several of the world's fastest supercomputers. The affected supercomputer is used by over 6,000 clients, including Chinese state-run agencies. The stolen data includes defense documents, missile schematics, and research data from aerospace engineering and other fields. The breach was discovered in early February 2026, when an anonymous user uploaded a sample of the dataset to a Telegram channel. Cybersecurity researchers have verified the data and confirmed that the hackers were offering it for sale.
