The hacker shared a partial 217-page file directory as purported evidence of the breach, stating that the stolen trove includes unpublicized raw data from 400+ national-level scientific research projects, core algorithm source codes for NSCC’s next-generation supercomputing systems, confidential aerospace engineering simulation results, pre-clinical trial data for 120+ under-development biopharmaceutical products, and internal collaboration documents between NSCC and 78 global university and research partners. As of press time, NSCC has not released an official statement confirming or denying the alleged breach, while China’s national cybersecurity regulatory body has launched a full investigation into the authenticity of the hacker’s claims. Cybersecurity experts specializing in critical infrastructure protection note that 10PB of data is equivalent to the storage capacity of roughly 2.3 million DVD discs, meaning if verified, the leak would cause unprecedented damage to global scientific research intellectual property. “NSCC’s supercomputing facilities support more than 42% of China’s national key R&D projects, spanning semiconductor design, quantum computing development, climate change modeling, deep sea exploration and advanced manufacturing,” explained Dr. Elena Marquez, senior researcher at the Global Critical Infrastructure Security Institute. “A data loss of this scale would not only erase years of research progress for Chinese teams, but also expose unpublicized findings of international partners that share data with NSCC, triggering widespread IP disputes across the global scientific community.” Experts also emphasized that the incident serves as a critical wake-up call for supercomputing centers worldwide. For decades, most national supercomputing facilities have prioritized computational speed over layered security protection, leaving gaps in internal permission management, third-party supply chain security and end-to-end data encryption that threat actors are increasingly targeting. Leading global cybersecurity firms are currently monitoring dark web markets for signs of the stolen NSCC data being put up for sale, and have advised all research institutions with NSCC partnerships to conduct immediate audits of shared data assets and upgrade access control protocols to mitigate potential risks.
