China suffered a massive leak from its National Supercomputing Center in Guangzhou, exposing about 10,000 terabytes of sensitive research, including some defense‑related material





A massive trove of data — roughly 10 petabytes (10,000 terabytes) — from China’s National Supercomputing Center in Guangzhou (NSCC‑GZ) was leaked and put up for sale on the dark web.

• What the center is
NSCC‑GZ hosts the Tianhe‑2 supercomputer, used for:

advanced scientific research

aerospace modeling

defense‑related simulations

high‑performance computing projects

• What the leaked data includes
Reports say the data contains:

aerospace and aviation research

files linked to major Chinese state contractors

sensitive engineering and simulation data

some defense‑related material

• What it does not appear to be
Not a PLA military command center

Not confirmed “top secret military” files

Not confirmed to be a foreign government hack
(the data was simply offered for sale)

• Why it matters
The scale is enormous — one of the largest known data leaks involving Chinese high‑tech and defense‑adjacent research.
