Title: Defeat Information Leakage from Browser Extensions Via Data 
Obfuscation

Host: Songqing Chen

Abstract
****************************************
Today web browsers have become the de facto platform for Internet users. 
This makes browsers the target of a lot of attacks. With the security 
considerations from the very beginning, Chrome offers more protection 
against exploits via benign-but-buggy extensions.  However, more and more 
attacks have been launched via malicious extensions while there is no 
effective solution to defeat such malicious extensions. As user's 
sensitive information is often the target of such attacks, in this talk, 
I will discuss how to proactively defeat information leakage with our 
iObfus framework. A proto-type has been implemented and iObfus works 
seamlessly with the Chromium 25. Evaluation against malicious extensions 
shows the effectiveness of iObfus, while it only introduces trivial 
overhead to benign extensions.
