Aiming at the problem that the current Android malware detection method has insufficient ability to detect unknown applications, this study proposes an Android malware detection method based on the textCNN neural network model. This method uses a variety of trigger mechanisms to induce the potential malicious behavior of the application from different levels. For function calls at different levels, the specific hook technology is used to collect the application behavior. For the collected behavior logs, the fastText algorithm is used to extract word vectors. Finally, the textCNN model is used to detect and identify Android applications based on behavior logs. Experimental results show that the average accuracy of the method for detecting Android malicious applications reaches 93.3%, which verifies that the method has high effectiveness and correctness for detecting Android malwares.
