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.

Hacking Team, a Milan-based developer of “offensive security” technology that markets its products to governments and law enforcement agencies around the world, was significantly compromised when hackers leaked nearly 400 GB of its internal data, including emails, client files, and financial documents. The leak was announced via Hacking Team’s own compromised Twitter account, and the content made publicly available. Among other things, the leaked documents confirmed our findings that the company sells its software to several governments with repressive human rights records, such as Ethiopia, Sudan, Rwanda, Saudi Arabia, Kazakhstan, and more.

According to state media organization People’s Daily, Apple agreed to Chinese government “security checks.” Citizen Lab Research Fellow Jason Q. Ng expressed concern that this practice may set a trend of compliance to such demands amongst other firms.
In an article contributed to the National Post, Citizen Lab Postdoctoral Fellow Christopher Parsons explains that the activities of the Communications Security Establishment constitute spying on Canadians. Parsons summarizes several findings regarding the mandate and practices of the organization leaked over the last year and a half, many of which strongly undermine CSE’s claim that Canadians are not “targeted” by domestic security agencies.
