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.

Asia Chats: LINE and KakaoTalk Disruptions in China

In this post we examine how the Great Firewall of China is implementing DNS tampering and HTTP request filtering on KakaoTalk and LINE domains, which is disrupting service of the applications as a result. We find that Flickr and OneDrive are also blocked through DNS tampering. We also analyze recent changes to the LINE keyword filtering list.

Who’s the Boss? The difficulties of identifying censorship in an environment with distributed oversight: A large-scale comparison of Wikipedia China with Hudong and Baidu Baike

This project is a large-scale comparison of the three services, matching thousands of Chinese-language Wikipedia articles with their in-China counterparts, in order to identify the “content gaps” in the two baike. The difficulties of identifying traditional cases of information control in environments with distributed oversight like online enclopedias will be discussed. The research methodology and some of the initial results (including tables of possibly censored articles) will also be presented.

Using the China Chats surveillance/censorship keyword list: analyzing blocked terms, search result numbers, and overlaps of censored terms between services

Working with the just-released China Chats keyword list, Jason Q. Ng extended The Citizen Lab/UNM’s analysis by checking whether each of the 4,256 keywords was blocked from searching on Sina Weibo. This report includes further analysis and examination of other potential censorship tactics by Weibo revealed in the data.

China Chats: Tracking surveillance and censorship in TOM-Skype and Sina UC

In this collaborative study between the Citizen Lab and Department of Computer Science at the University of New Mexico we examine the implementation of censorship and surveillance in two IM clients maintained by two different Chinese companies. For a period of more than a year and a half, we downloaded and decrypted the censorship and surveillance keyword lists used by the client software of two IM programs used in China: TOM-Skype and Sina UC.

Characterizing Large-scale Routing Anomalies: A Case Study of the China Telecom Incident

It raises many important questions about how we characterize and reason about large-scale routing incidents when they occur.
