MaSS-Droid: Android Malware Detection Framework Using Multi-Layer Feature Screening and Stacking Integration

In recent years, the frequent emergence of Android malware has posed a significant threat to user security. The redundancy of features in malicious software samples and the instability of individual model performance have also introduced numerous challenges to malware detection. To address these issues, this paper proposes a malware detection framework named <b>Mass-Droid</b>, based on <b>M</b>ulti-feature <b>a</b>nd Multi-layer <b>S</b>creening for adaptive <b>S</b>tacking integration. First, three types of features are extracted from APK files: permission features, API call features, and opcode sequences. Then, a three-layer feature screening mechanism is designed to effectively eliminate feature redundancy, improve detection accuracy, and reduce the computational complexity of the model. To tackle the problem of high performance fluctuations and limited generalization ability in single models, this paper proposes an adaptive Stacking integration method (Adaptive-Stacking). By dynamically adjusting the weights of base classifiers, this method significantly enhances the stability and generalization performance of the ensemble model when dealing with complex and diverse malware samples. The experimental results demonstrate that the MaSS-Droid framework can effectively mitigate overfitting, improve the model's generalization capability, reduce feature redundancy, and significantly enhance the overall stability and accuracy of malware detection.
