As part of the observatory, Censored Planet develops and maintains various next-generation remote measurement techniques
Satellite measures DNS manipulation by sending requests to public DNS nameservers, and comparing their responses with a set of hueristics developed for detecting censorship.
Satellite-v2 is the next generation of the Satellite measurement technique that solves many of the limitations of Satellite-v1
Quack and it's extension Hyperquack are novel techniques for measuring keyword blocking at the application layer in a scalable, longitudinal, and safe way. Quack uses echo and discard servers to detect DPI blocking of traffic based on request headers. Hyperquack measures keyword blocking at the application layer using infrastructural web servers as vantage points. Hyperquack detects interference with HTTP and HTTPS traffic by making use of publicly accessible web-servers with consistent behavior.
CenTrace is a general-purpose application-layer censorship traceroute tool, that sends TTL-limited HTTP and TLS packets to detect the network locations of censorship devices.
CenFuzz is a deterministic censorship and middlebox fuzzing tool that performs application-layer fuzzing strategies on blocked connections such that the same strategies are performed across all tested devices.
