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.
This report describes the results of two independent security audits of Smart Sheriff, one by researchers who collaborated at the 2015 Citizen Lab Summer Institute (held at the Munk School of Global Affairs, University of Toronto), and the other by the auditing firm Cure53. The combined audits identified twenty-six security vulnerabilities in recent versions of Smart Sheriff (versions 1.7.5 and under). These vulnerabilities could be leveraged by a malicious actor to take control of nearly all Smart Sheriff accounts and disrupt service operations.
