A hacker has allegedly stolen more than 10 petabytes of data from China's National Supercomputing Center in Tianjin, according to a report from CNN. The claimed breach includes highly classified defense documents and missile schematics.

The data breach, if verified, would represent one of the largest known thefts of sensitive military and research data from a Chinese government facility. The National Supercomputing Center in Tianjin operates the Tianhe supercomputer systems, which have been used for both civilian research and defense-related computing tasks.

The hacker's claims include access to documents marked at high classification levels, though independent verification of the breach remains pending. Chinese authorities have not publicly confirmed the incident.

The breach claim comes amid heightened concerns about cybersecurity at research institutions worldwide. Supercomputing centers typically house vast repositories of scientific and engineering data, making them high-value targets for both state-sponsored and independent threat actors.

The alleged theft includes not only defense materials but also what the hacker described as operational data from the facility's computing systems.
