Jeffrey Knockel is a research fellow at the Citizen Lab. His work focuses on developing novel techniques to uncover harmful software behaviour. Through technical analysis of apps and networks, he reveals applications’ secret censorship rules and hidden surveillance activity, and he exposes how gaps in applications’ security put the safety and privacy of the public’s data at risk.
