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.

This post is an introduction to Asia Chats a research project analyzing
information controls and privacy in mobile messaging applications used
in Asia. The project will produce a series of reports that will begin
with a focus on WeChat, LINE, and KakaoTalk. Reports will include
analysis based on our technical investigation of censorship or
surveillance functionality, assessment of privacy issues surrounding
these applications’ use and storage of user data, and comparison of the
terms of service and privacy policies of the applications.

This report by Seth Hardy (Senior Security Analyst, Citizen Lab)
describes the technical details of client-side censorship functionality
in the LINE messenger client for Android, and a method for disabling it.
This post is the first in a series of research reports analyzing
information controls and privacy in mobile messaging applications used
in Asia. An introduction to the project can be found here
