Abstract: Cases of Android security defence system penetration has increasedin recent years. This increase has prompted the investigation and evaluation of the execution behaviours of malicious applications in mobile systems, especially, Android Operating Systems (OSs). The main challenge of the detection systems is making many false alarms which are related to misclassifying the malicious behaviours as normal. This study proposes a new approach that combines the Android mobile features for targeting malwares and uses a deep feed forward neural network for detecting malicious activities or behaviours. The study employs different sets of mobile malware features to train and test the detection model. Results showed improved accuracy of detection rates when the detection model is trained with combined features.
