An anonymous Telegram account posted a sample of a purported data trove on Feb. 6 and said it contained research across aerospace engineering, military research, bioinformatics, fusion simulations and more. Cybersecurity experts who reviewed the material said the cache may have been taken from the National Supercomputing Center in Tianjin and could be one of the largest breaches ever tied to China.
The sample was posted by an account called FlamingChina, which also claimed the files were linked to the Aviation Industry Corporation of China, the Commercial Aircraft Corporation of China and the National University of Defense Technology. Experts said the broader dataset could exceed 10 petabytes, and that access appeared to be sold in tiers, with a limited preview offered for a few thousand dollars and full access for hundreds of thousands of dollars, all paid in cryptocurrency.
The alleged leak matters because the Tianjin center is a state-controlled Chinese supercomputer node that provides infrastructure services to more than 6,000 clients across the country, including work tied to science and defense. Researchers who examined the samples said they were able to access the system with relative ease and extract large volumes of data over several months without setting off detection.
That ease is part of what makes the claims so troubling. The samples reportedly included documents marked secret in Ukrainian, technical files, animations, images of defense equipment, missiles and weapon systems, but independent verification of where the data came from and whether it is genuine could not be completed. For now, the breach remains unconfirmed, but if the material is real, it would point to deep weaknesses in China’s technological infrastructure and the security around a China supercomputer node that supports sensitive research.
