TL‐GNN: Android Malware Detection Using Transfer Learning

ABSTRACTMalware growth has accelerated due to the widespread use of Android applications. Android smartphone attacks have increased due to the widespread use of these devices. While deep learning models offer high efficiency and accuracy, training them on large and complex datasets is computationally expensive. Hence, a method that effectively detects new malware variants at a low computational cost is required. A transfer learning method to detect Android malware is proposed in this research. Because of transferring known features from a source model that has been trained to a target model, the transfer learning approach reduces the need for new training data and minimizes the need for huge amounts of computational power. We performed many experiments on 1.2 million Android application samples for performance evaluation. In addition, we evaluated how well our framework performed in comparison with traditional deep learning and standard machine learning models. In comparison with state‐of‐the‐art Android malware detection methods, the proposed framework offers improved classification accuracy of 98.87%, a precision of 99.55%, recall of 97.30%, F1‐measure of 99.42%, and a quicker detection rate of 5.14 ms using the transfer learning strategy.

SNDGCN: Robust Android malware detection based on subgraph network and denoising GCN network

Android malware seriously affects the use of Android applications, and a growing number of Android malware developers are using adversarial attacks to evade detection by deep learning models. This work proposes an Android malware detection model based on the Android function call graph (FCG) and the denoising graph convolutional network (GCN) that is resistant to adversarial attacks. Methods are also proposed to simplify the FCG to reduce its size, and to construct vertex feature vectors. Because attackers may employ adversarial attack methods, the proposed model uses the subgraph network (SGN) to detect the underlying structural features of the FCG to discover the degree of the obfuscation attack. A denoising graph neural network (GNN) is designed, and the 1-Lipschitz-based neural network denoising method is applied to graph convolution. Moreover, the degree of denoising is adjusted according to the degree of obfuscation, which enhances the robustness of the model. The GCN performs the feature vector extraction of the FCG, and a multilayer perceptron (MLP) is used as the classifier. The results of experiments show that the F1 value of the proposed Android malware detection method is higher than those of other malware detection models for different levels of obfuscation attacks, thus demonstrating its effectiveness against such attacks.

A New Wrapper-Based Feature Selection Technique with Fireworks Algorithm for Android Malware Detection

Smartphone use has expanded dramatically in recent years, particularly for Android-based smartphones, due to their wide availability and competitive pricing compared to non-Android devices. The significant increase in the use of Android applications has resulted in a spike in the number of malicious applications, which represent a severe danger to user privacy. In this paper, the authors proposed FWA-FS, a novel method for Android malware detection with feature selection based on the fireworks algorithm. Static analysis is used in the proposed technique to classify applications as benign or malicious. To describe applications, they employ permissions derived from APK files as feature vectors. The most important features were then chosen using the proposed FWA-FS method. Finally, to develop classification models, different machine learning algorithms were trained using specified features. According to experimental findings, the suggested strategy can greatly enhance classification performance with an average increase of 6% and 25% in accuracy for KNN and Naïve Bayes respectively.

A Low Computational Cost Method for Mobile Malware Detection Using Transfer Learning and Familial Classification Using Topic Modelling

With the extensive use of Android applications, malware growth has been increasing drastically. The high popularity of Android devices has motivated malware developers to attack these devices. In recent times, most researchers and scholars have used deep learning approaches to detect Android malware. Although deep learning techniques provide good accuracy and efficiency, they require high computational cost to train huge and complex data sets. Hence, there is a need for an approach that can efficiently detect novel malware variants with a minimum computational cost. This paper proposes a novel framework for detecting and clustering Android malware using the transfer learning and the topic modelling approach. The transfer learning approach minimizes new training data by transferring well-known features from a qualified source model to a destination model, and hence, a high amount of computational power is not required. In addition, the proposed framework clusters the detected malware variants into their corresponding families with the help of Latent Dirichlet Allocation and hierarchical clustering techniques. For performance assessment, we performed several experiments with more than 50K Android application samples. In addition, we compared the performance of our framework with that of similar existing traditional machine learning and deep learning models. The proposed framework provides better accuracy of 98.3% during the classification stage by using the transfer learning approach as compared to other state-of-the-art Android malware detection techniques. The high precision value of 98.7% is obtained during the clustering stage while grouping the obtained malicious applications into their corresponding malware families.
