Root access to the great firewall.

DomainTools researcher Daniel Schwalbe's two-part investigation "Inside the Great Firewall" analyzes a 500–600GB leak of internal documents, source code, diagrams, packet captures, and telemetry that reveal how systems such as Traffic Secure Gateway, MAAT, Redis-based analytics, and modular DPI engines coordinate to censor, surveil, and fingerprint users at scale, portraying the Great Firewall as an adaptive censorship-industrial complex.
