Access Control for Plugins in Cordova-Based Hybrid Applications

Hybrid application frameworks such as Cordova allow mobile application (app) developers to create platformindependent apps. The code is written in JavaScript, with special APIs to access device resources in a platform-agnostic way. In this paper, we present a novel app-repackaging attack that repackages hybrid apps with malicious code; this code can exploit Cordova’s plugin interface to tamper with device resources. We further demonstrate a defense against this attack through the use of a novel runtime access control mechanism that restricts access based on the mobile user’s judgement. Our mechanism is easy to introduce to existing Cordova apps, and allows developers to produce apps that are resistant to app-repackaging attacks.
