The Great Firewall of China (GFW) experienced the largest leak of internal documents in its history on Thursday September 11, 2025. Over 500 GB of source code, work logs, and internal communication records were leaked, revealing details of the GFW’s research, development, and operations.
The leak originated from a core technical force behind the GFW: Geedge Networks (whose chief scientist is Fang Binxing) and the MESA Lab at the Institute of Information Engineering, Chinese Academy of Sciences. The documents show that the company not only provides services to governments in places like Xinjiang, Jiangsu, and Fujian, but also exports censorship and surveillance technology to countries such as Myanmar, Pakistan, Ethiopia, Kazakhstan, and other unidentified country under the “Belt and Road” framework.
The significance and far-reaching implications of this leak are substantial. Due to the massive volume of data, GFW Report will continue to analyze and provide updates on the current page and on the Net4People.
