Thank you to the artifact evaluators for examining -our artifacts. - -## Artifacts Abstract -In this paper, we present the first techniques to automate the discovery of new -censorship evasion techniques purely in the application layer. We present a -general solution and apply it specifically to HTTP and DNS censorship in China, -India, and Kazakhstan. Our automated techniques discovered a total of 77 unique -evasion strategies for HTTP and 9 for DNS, all of which require only -application-layer modifications, making them easier to incorporate into apps and -deploy. We analyze these strategies and shed new light into the inner workings -of the censors. We find that the success of application-layer strategies can -depend heavily on the type and version of the destination server. Surprisingly, -a large class of our evasion strategies exploit instances in which censors are -more RFC-compliant than popular application servers. - -For the purposes of this submission, our artifacts are (1) the strategies we -present in the paper and (2) the code used to implement them. We developed our -fuzzer by building off of the open-source Geneva project -(https://github.com/Kkevsterrr/geneva), but our code has not yet merged into -that repository publicly. Therefore, we have provided the full modified -codebase to assist in the evaluation. - -For this artifact evaluation, we demonstrate how the reader can evaluate (1) -that our strategies can generate modified requests; (2) that our strategies can -evade censorship. Optionally, the evaluator can test for themselves that our -tool can fuzz HTTP requests. ## Evaluation |
