This post describes the results of Internet scanning we recently conducted to identify the users of FinFisher, a sophisticated and user-friendly spyware suite sold exclusively to governments. We devise a method for querying FinFisher’s “anonymizing proxies” to unmask the true location of the spyware’s master servers. Since the master servers are installed on the premises of FinFisher customers, tracing the servers allows us to identify which governments are likely using FinFisher. In some cases, we can trace the servers to specific entities inside a government by correlating our scan results with publicly available sources.
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.
