Moreover, we found that most methods are assessed with (i) malware running isolated in an emulator and (ii) malware running for a brief period. An increasing trend is seen in malware that use techniques to avoid detection in virtual environments, thereby making methods based on analysis in virtual environments less effective than methods based on analysis on real devices. Īn important limitation is that in most studies of malware detection, virtual environments are used, e.g., analysis on a PC, instead of real mobile devices.

Dynamic analysis has advantages over static analysis but methods are still imperfect, ineffective, and incomprehensive. Static analysis refers to the analysis of malware outside runtime, e.g., by analysing the installation package of a malware app. Dynamic analysis refers to the analysis of malware during runtime, i.e., while the application is running. This classifier can then be deployed on mobile phones to detect future malware based on the dynamic sensor data similar to the dataset, i.e., dynamic analysis.Īcademic work is mainly divided into dynamic analysis and static analysis of mobile malware. These machine learning classifiers can be trained on a cluster on a large dataset, resulting in a classifier. We show different training approaches for each of the classifiers, showing their performance on individual and general cases.

In this article, we present an overview of the performance of state-of-the-art machine learning classifiers using sensor data on the Android mobile operating system. ĭetection of mobile malware is becoming increasingly relevant, with machine learning showing the most promise. Additionally, over the past years, malware authors have become less recreational-driven and more profit-driven as they are actively searching for sensitive, personal, and enterprise information. Criminals try to exploit vulnerabilities on smartphones of other people for their own purposes. The rise in smartphone users has also led to an increase in malicious programs targeting mobile devices, i.e., mobile malware. The number of active smartphone users globally is expected to be 7.3 billion by 2025.

Nowadays smartphones have become an integral part of life, with people using their phones in both their private and professional life. The Random Forest, K-Nearest Neighbours, and AdaBoost classifiers achieve F1 scores above 0.72, an FPR below 0.02 and, an FNR below 0.33, when trained separately to detect each subtype of Mobile Trojans. Our results show that the Random Forest classifier performs best as a general malware classifier: across 10 subtypes of Mobile Trojans, it achieves an F1 score of 0.73 with a False Positive Rate (FPR) of 0.009 and a False Negative Rate (FNR) of 0.380. None of the measured feature sets require privileged access. We show classification results on different feature sets, making a distinction between global device features, and specific app features. Using these dynamic features we apply state-of-the-art machine learning classifiers: Random Forest, K-Nearest Neighbour, and AdaBoost. The focus of this article is on dynamic hardware features. We examine which features, i.e., aspects, of a device, are most important to monitor to detect (subtypes of) Mobile Trojans. We use a real-life dataset containing device and malware data from 47 users for a year (2016). The ML-classifiers use device information such as the CPU usage, battery usage, and memory usage for the detection of 10 subtypes of Mobile Trojans on the Android Operating System. In this article, we provide an overview of the performance of machine learning (ML) techniques to detect malware on Android, without using privileged access. Detection methods for mobile malware exist but are still limited.

The number of active smartphone users is expected to grow, stressing the importance of research on the detection of mobile malware. They are an increasing problem, as seen with the rise of detected mobile malware samples per year. Mobile malware are malicious programs that target mobile devices.
