Overview
- The alleged breach, which major outlets reported Wednesday, involves a group calling itself FlamingChina that posted samples in February and is offering access for cryptocurrency.
- Experts who reviewed the samples saw documents marked secret in Chinese along with technical files and weapon and flight simulations tied to aerospace and defense research.
- Researchers say the intruder claimed entry through a compromised VPN then used a botnet to pull data in small chunks across many systems over about six months to avoid detection.
- Several analysts consider the samples plausible while others question whether 10 petabytes could be exfiltrated and stored unnoticed, and the full archive has not been independently verified.
- The Tianjin center supports about 6,000 clients across science and defense, and experts say a trove this size would likely be most usable by state intelligence services and could spur tighter security for high‑performance computing hubs.
