Massive China Supercomputer Breach Exposes Defense Data for Sale

A hacker group has allegedly breached a Chinese state-run supercomputer and stolen over 10 petabytes of highly sensitive data, including defense documents and missile schematics. The data is believed to have been taken from the National Supercomputing Center in Tianjin, a key infrastructure hub supporting thousands of scientific and government organizations. The stolen dataset is now reportedly being offered for sale online for large sums via cryptocurrency.

Cybersecurity experts who reviewed samples of the leaked data suggest the breach could be genuine, with files linked to aerospace, military research, and advanced simulations. The attacker is said to have gained access through a compromised VPN and used a distributed botnet to extract data over several months without triggering detection systems. This method allowed small amounts of data to be siphoned continuously, avoiding large-scale alerts.

If confirmed, this incident could rank among the largest cyber breaches in China’s history and raises serious concerns about the security of critical infrastructure. The scale and sensitivity of the data make it highly valuable for cyber espionage and nation-state actors. The breach highlights ongoing weaknesses in cybersecurity defenses and the growing risks surrounding large-scale data storage systems.
