UC Browser is the most popular mobile web browser in China and India, boasting over 500 million users. This report provides a detailed analysis of how UC Browser manages and transmits user data, particularly private data, during its operation. Our research was prompted by revelations in a document leaked by Edward Snowden on which the Canadian Broadcasting Corporation (CBC) was preparing a story.
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.
A new report, entitled “Communities @ Risk: Targeted Digital Threats Against Civil Society,” involved 10 civil society groups that enrolled as study subjects over a period of four years. The study sought to obtain greater visibility into an often overlooked digital risk environment affecting–whether they know it or not–many of society’s most essential institutions.
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.
The May 2014 coup d’etat in Thailand was the 19th coup attempt in the country’s history. It stands out from previous coups due to the military junta’s focus on information controls. In this report we document the results of network measurements to determine how the Internet is currently being filtered in Thailand and discuss other forms of information control implemented in the coup’s aftermath.
In this report, we document the results of network measurement tests we ran to determine how the Internet is being filtered in Iraq in reaction to ongoing insurgency in the country. The results identify 20 unique URLs that are blocked on three Iraq-based Internet Service Providers. Notably, none of the 7 websites we tested that are affiliated with, or supportive, of the jihadist insurgent group the Islamic State in Iraq and Greater Syria (ISIS) were found to be blocked.
This report is the third in a series which analyzes regionally-based keyword censorship in LINE, a mobile messaging application developed by LINE Corporation.
