Every Rose Has Its Thorn: Censorship and Surveillance on Social Video Platforms in China

In this paper presented at USENIX FOCI 2015 we use reverse engineering to provide a view into how keyword censorship operates on four popular social video platforms in China: YY, 9158, Sina Show, and GuaGua. We also find keyword surveillance capabilities on YY. Our findings show inconsistencies in the implementation of censorship and the keyword lists used to trigger censorship events between the platforms we analyzed. We reveal a range of targeted content including criticism of the government and collective action. These results provide evidence that there is no monolithic set of rules that govern how information controls are implemented in China.

China’s Great Cannon

This post describes our analysis of China’s “Great Cannon,” our term for an attack tool that we identify as separate from, but co-located with, the Great Firewall of China. The first known usage of the Great Cannon is in the recent large-scale novel DDoS attack on both GitHub and servers used by GreatFire.org.

Asia Chats: Update on Line, KakaoTalk, and FireChat in China

In this post we report updates on how LINE, KakaoTalk, OneDrive and Flickr are being disrupted in China. We find that Flickr and OneDrive remain consistently blocked, but LINE and KakaoTalk show inconsistent fluctuation between accessibility and inaccessibility. We also analyze security and privacy of FireChat and test accessibility of the service in China.
