Abstract: With Android’s widespread adoption as the leading mobile operating system, it has become a prominent target for malware attacks. Many of these attacks employ advanced obfuscation techniques, rendering traditional detection methods, such as static and dynamic analysis, less effective. Image-based approaches provide an alternative for effective detection that addresses some limitations of conventional methods. This re-search introduces a novel image-based framework for Android malware detection. Using the CICMalDroid 2020 dataset, Dalvik Executable (DEX) files from Android Package (APK) files are extracted and converted into grayscale images, with dimensions scaled according to file size to preserve structural characteristics. Various Convolutional Neural Network (CNN) models are then employed to classify benign and malicious applications, with performance further enhanced through a weighted voting ensemble optimized by Bayesian Optimization to balance the contribution of each model. An ablation study was conducted to demonstrate the effectiveness of the six-model ensemble, showing consistent improvements in accuracy as models were added incrementally, culminating in the highest accuracy of 99.3%. This result surpasses previous research benchmarks in Android malware detection, validating the robustness and efficiency of the proposed methodology.
