"In a historic breach of China's censorship infrastructure, over 500 gigabytes of internal data were leaked from Chinese infrastructure firms associated with the Great Firewall (GFW) in September 2025. Researchers now estimate the full dump is closer to approximately 600 GB, with a single archive comprising around 500 GB alone. The material includes more than 100,000 documents, internal source code, work logs, configuration files, emails, technical manuals, and operational runbooks."
"Among the revealed artifacts are RPM packaging server files, the packaging infrastructure used for distributing software artifacts, project management data from Jira and Confluence showing internal tickets, feature requests, bug reports, and deployment histories, and communications and engineering documents showing how censorship tools are tested against VPNs, Tor, and other circumvention methods, including methods of deep packet inspection (DPI), SSL fingerprinting, and filtering logic."
Approximately 600 GB of internal data linked to firms supporting the Great Firewall were leaked in September 2025, with a single archive near 500 GB. The dump contains more than 100,000 documents and thousands of files, including source code, work logs, configuration files, emails, technical manuals, and operational runbooks. Artifacts include RPM packaging server files and packaging infrastructure, plus project management data from Jira and Confluence showing tickets, feature requests, bug reports, and deployment histories. Communications and engineering documents reveal how censorship tools are tested against VPNs, Tor, and other circumvention methods using DPI, SSL fingerprinting, and filtering logic.
