Illuminating and Defending Against Targeted Government Surveillance of Activists
Bill Marczak is a Computer Science postdoc at UC Berkeley and Senior Research Fellow at The Citizen Lab. Bill's research focuses on identifying and tracking nation-state information controls employed against dissidents, as well as government-exclusive "lawful intercept" malware tools including FinFisher, Hacking Team’s RCS, and NSO Pegasus. Bill’s work resulted in the identification of the Great Cannon, an attack tool employed by China that hijacked millions of users’ web browsers around the world to conduct Denial of Service (DoS) attacks for censorship purposes, as well as the discovery of the first iPhone zero-day remote jailbreak seen used in the wild, sold by Israeli firm NSO Group to governments around the world to facilitate surveillance of mobile phones.
