This report describes the latest iteration in a long-running espionage campaign against the Tibetan community. We describe how the attackers continuously adapt their campaigns to their targets, shifting tactics from document-based malware to conventional phishing

A second audit of South Korea’s Smart Sheriff application reveals that there are numerous unresolved vulnerabilities that put minor children and parental users of the application at serious risk.

This report analyzes a campaign of targeted attacks against an NGO working on environmental issues in Southeast Asia. Our analysis reveals connections between these attacks, recent strategic web compromises against Burmese government websites, and previous campaigns targeting groups in the Tibetan community.

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.

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.
