Nipdroid: An Enhanced Detection Mechanism for Android IPC
Chen Chen, Jia Song, Weidong Liu · Advanced materials research · 2014
As one of the most popular mobile operating system, Android has been troubled by privilege escalation attacks. This is because that the original Android ignores the inspection of transmitted data inintent. It only checks the permission ofintentto determine whether the Inter-Process Communication (IPC) could continue. We developed Nipdroid to solve the mentioned defect in Android IPC detection. Nipdroid is based on the technology of marking and tracking sensitive data. After the original Android detection, Nipdroid extracts the sensitive tags fromintent, and matches them with the permission lists of both communication apps, and then checks whether there is unreasonable data transmission in IPC. Experiments show that Nipdroid is effective on both preventing privilege escalation attacks and protecting user's sensitive data.
