Machine Learning (ML) has found it particularly useful in malware detection. However, as the malware evolves very fast, the stability of the feature extracted from malware serves as a critical issue in malware detection. Recent success of deep learning in image recognition, natural language processing, and machine translation indicate a potential solution for stabilizing the malware detection effectiveness. We present a coloR-inspired convolutional neuRal network-based AndroiD malware Detection (R2-D2), which can detect malware without extracting pre-selected features (e.g., the control-flow of op-code, classes, methods of functions and the timing they are invoked etc.) from Android apps. In particular, we develop a color representation for translating Android apps into RGB color code and transform them to a fixed-sized encoded image. After that, the encoded image is fed to convolutional neural network for automatic feature extraction and learning, reducing the expert's intervention. We have collected over 1 million malware samples and 1 million benign samples according to the data provided by Leopard Mobile Inc. from its core product Security Master (which has 623 million monthly active users and 10k new malware samples per day). It is shown that R2-D2 can effectively detect the malware. Furthermore, we keep our research results and release experiment material on http://R2D2.TWMAN.ORG if there is any update.
