Sunday, July 22, 2018: 2:00 pm (Ritchie): This talk discusses modern practical attacks on the Tor anonymity network. The topics include penetrating Tor hidden services and infrastructure, as well as open-source intelligence, operational security, social engineering, and client side exploitation as they relate to the Tor network. Real-world examples are examined, and methods of self-defense are explored. This discussion will arm the audience with the knowledge they will need to engineer attack-resilient anonymous ecosystems, and to defend their liberty, their lives, and their human rights of privacy, anonymity, and free speech in an age of ubiquitous surveillance.
