The National Supercomputer Centre in Tianjin appeared to have suffered a massive data leak of 10 Petabytes of internal data, including classified information.
About two months ago, we saw a sales announcement on a dark web forum by a hacker that goes by the name of “airborneshark1″. It offered a massive 10 petabyte data set that was apparently extracted from the National Supercomputer Centre of China (NSCC) in Tianjin.
It was re-upped again a few days ago, likely to drive up the bidding. The first post still offered the possibility of just taking a peek at the complete list of “obtained” datasets for measly 3,000 USD. This time around, it’s “all in”, it seems.
The group that has conducted the “hack” calls itself “Flaming China”. Their Telegram Channel seems to have existed since early Feb. It is doubtful this is a permanent group and rather an alias.
What is the NSCC?
The NSCC is a massive, government-owned data centre that provides academic institutions, SOEs and other partner organisations with resources to run very complex digital simulations.
Now, this data centre, of course, is also heavily facilitated by the military and their contractors and R&D partners to run challenging technical virtualisation processes.
The data ranges from PDFs of reports and handbooks to very technical files that contain radar test data, as well as renderings of physics simulations, series of test calculations, etc.
One aspect in which the NSCC has been extensively used is simulating the effects of payloads and weapon systems on certain targets and materials. Mainly to collect significant data for further R&D, etc. Many of the documents are also rather recent, from 2024 and 2025.
HIMARS copycat
Taiwan plans to procure 28 additional sets of M-142 High Mobility Artillery Rocket Systems (HIMARS) and nine additional sets of National Advanced Surface-to-Air Missile Systems (NASAMS), military sources said yesterday.
Taiwan had previously purchased 29 HIMARS launchers from the US and received the first 11 last year. Once the planned HIMARS purchases are completed and delivered, Taiwan will have 57 HIMARS systems.
This document was an extensive testing report of an ammunition from 2025. It holds physical copycat models of a HIMARS truck (a system recently acquired by Taiwan), its armor and other components to include in the virtual target simulation, as well as an aircraft carrier and several bunker setups.
These models are created with $80 commercial software, such as AutoCAD. Chinese engineers are trying to copy the physical appearance of HIMARS rather than the technology that makes HIMARS fearsome in Ukraine and Iran.
Chinese engineers lack expertise and experience in real-world combat systems, so copycatting and reverse-engineering have become a habit rather than a focus on innovation.
