Researchers from the University of New Mexico and the Citizen Lab provide the first independent analysis of popular messaging app LINE’s end-to-end encryption security features and discuss gaps in communication between researchers, developers and users.

Citizen Lab Research Manager Masashi Crete-Nishihata was interviewed by Al Jazeera regarding censorship practices in popular Asian instant messaging applications.

This report is part of a series which analyzes regionally-based keyword censorship in LINE, a mobile messaging application developed by LINE Corporation. The most recent update to the censorship keyword list include a number of new entries as well as the introduction of regular expressions for more advanced keyword matching.

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.

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 report is the third in a series which analyzes regionally-based keyword censorship in LINE, a mobile messaging application developed by LINE Corporation. We document recent changes to the list of keywords used by LINE to trigger regionally-based keyword filtering for users with accounts registered to Chinese phone numbers.

This post is an update to our report on regionally-based keyword censorship in the popular chat application LINE. It covers responses from LINE Corporation to questions around censorship functionality in the application and recent changes to how keyword censorship and traffic encryption operate in the latest versions of LINE.

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
