10 petabytes of sensitive data stolen from China's National Supercomputing Center, hackers claim — daring heist would be largest ever China hack, covering 6,000 clients across science, defense, and beyond

A group calling itself FlamingChina claims it stole more than 10 petabytes from China’s National Supercomputing Center in Tianjin.

Leaked samples reportedly include material tied to aviation, defense, and scientific research, though the claim remains unverified.

Cybersecurity experts say the samples look plausible and suspect a compromised VPN plus slow, distributed theft over months.

If confirmed, the breach could expose a major critical-infrastructure weakness and sensitive data from defense and aerospace clients.
