RUNSECURE - Making the Droids more Secure Smartphones have become ubiquitous. They typically contain users' private and confidential data. This data is increasingly becoming the target of malicious applications, which try to steal such information. Alternatively, malicious applications may cause direct financial harm to a user, for example, by sending premium-rate SMSes. So as to mitigate these threats, we introduce RUNSECURE, a project that combines static information-flow tracking with dynamic bytecode instru- mentation. It is a framework for policy enforcement on real-word Android applications. In our current approach, we first apply static analysis so as to pre-analyse the applications for potential policy violations. The results obtained during this state serve to direct the instrumentation of bytecode with instructions for dynamic policy enforcement. The talk will give an overview of RUNSECURE and will show the current status of the project.
