Summary

Recent years have seen the Internet become a key vehicle for citizens around the globe to express political opinions and organize protests. This fact has not gone unnoticed, with countries around the world repurposing network management tools (e.g., URL filtering products) and protocols (e.g., BGP, DNS) for censorship. Previous work has focused on understanding how censorship is performed in specific countries. However, there are no major studies to understand global censorship trends over time, and to identify, on a global scale, the networks responsible for performing censorship. Also, repurposing network products for censorship can have an unintended international impact, which we refer to as censorship leakage. While there have been anecdotal reports of censorship leakage, there has yet to be a systematic study of censorship leakage at a global scale. We build a global censorship measurement platform (ICLab) and combine it with a general-purpose technique - boolean network tomography - to identify how a censor performs censorship and which AS on a network path is performing censorship.
