报告内容:Machine learning based malware classifiers often perform badly on detecting new malware, that is, their robustness is poor. This research takes Android apps as vehicle, investigates popular syntax-based features, some semantics-based features, and compares performance of classifiers combining popular machine learning methods and these features. We reveal one important reason affecting the robustness of malware classifiers: they do not capture general behavioural patterns of identified malware. One conclusion is: by using semantics-based features which are often hard to compute, i.e., sequences of API calls, the robustness of malware classifiers can be improved dramatically.
