Center node: "babelview evaluating the impact of code injection attacks in mobile webviews"
  Abstract: A Webview embeds a fully-fledged browser in a mobile application and allows that application to expose a custom interface to JavaScript code. This is a popular technique to build so-called hybrid applications, but it circumvents the usual security model of the browser: any malicious JavaScript code injected into the Webview gains access to the custom interface and can use it to manipulate the device or exfiltrate sensitive data. In this paper, we present an approach to systematically evaluate the possible impact of code injection attacks against Webviews using static information flow analysis. Our key idea is that we can make reasoning about JavaScript semantics unnecessary by instrumenting the application with a model of possible attacker behavior—the BabelView. We evaluate our approach on 25,000 apps from various Android marketplaces, finding 10,808 potential vulnerabilities in 4,997 apps. Taken together, the apps reported as problematic have over 3 billion installations worldwide. We manually validate a random sample of 50 apps and estimate that our fully automated analysis achieves a precision of 81% at a recall of 89%.
