This report describes privacy and security issues with Baidu Browser, a web browser for the Windows and Android platforms. Our research shows that the application transmits personal user data to Baidu servers without encryption and with easily decryptable encryption, and is vulnerable to arbitrary code execution during software updates via man-in-the-middle attacks. Much of the data leakage is the result of a shared Baidu software development kit, which affects hundreds of additional applications.
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.
At the 2015 USENIX Free and Open Communications on the Internet (FOCI) workshop, held in Washington DC on August 10, Citizen Lab and collaborators present three papers.
The papers include: investigation of censorship and surveillance on China’s most popular social video platforms, an updated analysis of China’s Great Canon, and examination of securing cookie-based identifiers from passive surveillance.
