China's Great Firewall suffers its biggest leak ever as 500GB of source code and docs spill online - censorship tool has been sold to three different countries - DataBreaches.Net

"Chinese censorship sprang a major leak on September 11, when researchers confirmed that more than 500GB of internal documents, source code, work logs, and internal communications from the so-called Great Firewall were dumped online, including packaging repos and operational runbooks used to build and maintain China's national traffic filtering system. The files appear to originate from Geedge Networks, a company that has long been linked to Fang Binxing - widely described as the "father" of the Great Firewall -"

"and from the MESA lab at the Institute of Information Engineering, a research arm of the Chinese Academy of Sciences. Contained in the leak are what appear to be full build systems for deep packet inspection platforms, as well as code modules that reference the identification and throttling of specific circumvention tools. Much of the stack is geared toward DPI-based VPN detection, SSL fingerprinting, and full-session logging."
