Presented at
Black Hat Asia 2015,
Unknown date/time
(Unknown duration).
In this talk, we will demonstrate and unveil the latest developments on browser specific weaknesses including creative new mechanisms to compromise confidentiality, successfully perform login and history detection, serve mixed content, deliver malicious ghost binaries without a C&C server, exploit cache/timing side channels to extract secrets from third-party domains, and leverage new HTML5 features to carry out more stealthy attacks. This is a practical presentation with live demos that will challenge your knowledge of the Same Origin Policy and push the limits of what is possible with today's web clients.
