Cellphones are increasingly becoming attractive targets of various malware, which not only cause privacy leakage, extra charges, and depletion of battery power, but also introduce malicious traffic into networks. In this paper, the authors seek system-level solutions to handle these security threats. Specifically, they propose a mandatory access control - based defense to blocking malware that launch attacks through creating new processes for execution. To combat more elaborated malware which redirect program flows of normal applications to execute malicious code within a legitimate security domain, they further propose using Artificial Intelligence (AI) techniques such as graphic turing test.
