Artificial intelligence has revolutionized many areas of research, including research on malicious application detection and classification. Nowadays, there are many approaches that learn from existing data and predict the classes of new data. Machine learning principles recommend a balance of classes in the training dataset, but the reality in the field is quite different. The majority of datasets used for malicious application detection are imbalanced. Class imbalance degrades classifier performance, so it is a common problem in classification tasks. This observation is much more significant in the area of android malware detection and classification. There are few works to our knowledge on the effects of imbalanced datasets in the field of android malware detection. Our contribution focuses on the impact of imbalanced datasets on the performance of different algorithms and the suitability of using evaluation metrics in android malware detection. We show that for malicious application detection, some classification algorithms are not suitable for unbalanced datasets. We also proved that some of the most used in literature performance evaluation metrics (Accuracy, Precision, Recall) are not very well adapted to imbalanced datasets. On the other hand, the metrics (Balanced accuracy, Geometric mean) are more adapted. These results were obtained by evaluating the performances of eleven classification algorithms and also the adequacy of the different evaluation metrics (Accuracy, Recall, Precision, F1 score, Balanced accuracy, Matthews corrcoef, Geometric mean, Fowlkes mallows).

Nowadays, analysis methods based on big data have been widely used in malicious software detection. Since android has become the dominator of smartphone operating system market, the number of android malicious applications are increasing rapidly as well, which attracts attention of malware attackers and researchers alike. Due to the endless evolution of the malware, it is critical to apply the analysis methods based on machine learning to detect malwares and stop them from leakaging our privacy information. In this paper, we propose a novel android malware detection method based on binary texture feature recognition by Local Binary Pattern and Principal Component Analysis, which can visualize malware and detect malware accurately. Also, our method analyzes malware binary directly without any decompiler, sandbox or virtual machines, which avoid time and resource consumption caused by decompiler or monitor in this process. Experimentation on 5127 benigns and 5560 malwares shows that we obtain a detection accuracy of 90%.

Several kinds of mobile applications are available on platforms offering various services to users. Both malware and good applications are found in software repositories, which is a major cybersecurity problem. To address this problem, machine learning approaches have been proposed in the literature for the detection of malware in general and malicious android applications in particular. But obfuscation techniques are used by some developers to hide malicious applications, which implies the need to update android malware detection *** the literature few works are focused on updating features. Our contribution is therefore an incremental learning approach capable of detecting android malware by taking into account both static and dynamic features. We propose through the UFILA approach an updated feature set for android malware detection and classification by adding new features. We evaluated 13 classification algorithms and selected the four most effective algorithms to implement our approach. The results obtained by our approach outperform several malware detection approaches in the literature. Our approach allows to detect malicious android applications based on static and dynamic features with feature updating. It also allows to efficiently classify the different classes.

Machine learning techniques have become an essential part of research into the detection and classification of malicious applications. There are several approaches or algorithms that learn from existing data and predict classes. Machine learning principles recommend a balance of classes in the training dataset, but the reality on the ground is quite different. The majority of datasets used for malicious application detection are unbalanced. Class imbalance degrades classifier performance, so it is a common problem in classification tasks. This observation is much more significant in the field of android malware detection and classification. There is little work to our knowledge on the effects of unbalanced datasets in the field of android malware detection. Our contribution focuses on the impact of unbalanced datasets on the performance of different algorithms and the relevance of using evaluation metrics in android malware detection. And the state of the databases from which researchers typically draw datasets. We show that for malicious application detection, some classification algorithms are not suitable for unbalanced datasets. We also prove that some of the most widely used performance evaluation metrics in the literature (Accuracy, Precision, Recall) are not very well suited to unbalanced datasets. On the other hand, the metrics (Balanced Accuracy, Geometric mean) are more suitable. These results were obtained by evaluating the performances of eleven classification algorithms as well as the adequacy of the different evaluation metrics (Accuracy, Recall, Precision, F1_score, Balanced accuracy, Matthews corrcoef, Geometric mean, Fowlkes_mallows). Also not all databases are accessible by researchers and many of these databases are not updated.

The ever-increasing growth of online services and smart connectivity of devices have posed the threat of malware to computer system, android-based smart phones, Internet of Things (IoT)-based systems. The anti-malware software plays an important role in order to safeguard the system resources, data and information against these malware attacks. Nowadays, malware writers used advanced techniques like obfuscation, packing, encoding and encryption to hide the malicious activities. Because of these advanced techniques of malware evasion, traditional malware detection system unable to detect new variants of malware. Cyber security has attracted many researchers in the past for designing of Machine Learning (ML) or Deep Learning (DL) based malware detection models. In this study, we present a comprehensive review of the literature on malware detection approaches. The overall literature of the malware detection is grouped into three categories such as review of feature selection (FS) techniques proposed for malware detection, review of ML-based techniques proposed for malware detection and review of DL-based techniques proposed for malware detection. Based on literature review, we have identified the shortcoming and research gaps along with some future directives to design of an efficient malware detection and identification framework.

Deep learning in general and convolutional architectures, in particular, have pushed the limits of the current state of the art in the field of computer vision and the processing of natural languages and speech. Recently, these techniques have been applied to detect mobile malware and have once again shown their ability to remedy this type of problem. However, the most suitable deep network architecture for malware detection remains an open issue. In this paper, we investigate the possibilities of convolutional neural networks for efficient detection of mobile malware. Specifically, we address the impact of using inception based and multichannel architectures on network performance. We achieve an accuracy of 92% using a multichannel model on a set of 50000 malware and 50000 benign applications.

As a mature and open mobile operating system, android runs on many IoT devices, which has led to android-based IoT devices have become a hotbed of malware. Existing static detection methods for malware using artificial intelligence algorithms focus only on the java code layer when extracting API features, however there is a lot of malicious behavior involving native layer code. Thus, to make up for the neglect of the native code layer, we propose a heterogeneous information network-based android malware detection method with cross-layer features. We first translate the semantic information of apps and API calls into the form of meta-paths, and construct the adjacency of apps based on API calls, then combine information from different meta-paths using multi-core learning. We implemented our method on the dataset from VirusShare and AndroZoo, and the experimental results show that the accuracy of our method is 93.4%, which is at least 2% higher than other related methods using heterogeneous information networks for malware detection.

The rising popularity and open-source model of the android operating system has made it a main target for attackers creating malware applications. With the mobile industry being an expanding device ecosystem, there is a critical need for developing effective methods to protect against mobile malware. Recognizing the latest approaches and their limitations, we have conducted a comprehensive empirical analysis on the applicability of knowledge graphs for malware detection in view of the influence of the scoring functions, the vector dimension, the stability of the obtained results, the performance of the individual classifiers, and other important time dependencies. In addition, we propose a knowledge-graph based method aimed at improving the quality of classification input data, while offering greater interfacing capabilities with external knowledge and lower computational complexity. The proposed method offers a new perspective on working with android malware, demonstrating a unique data processing pipeline for malware sample identification and encouraging further innovation in the field. Our findings demonstrate that knowledge graph representation is not only feasible, but also provides well-performing results, remaining competitive with state-of-the-art approaches.
