About the Event

The detection of malware and network attacks increasingly relies on machine learning techniques, which utilize multiple features to separate the malicious and benign behaviors. The effectiveness of these techniques primarily depends on the feature engineering process, which is based on human knowledge and intuition. However, given the adversaries’ efforts to evade detection and the growing volume of security reports and publications, the human-driven feature engineering likely draws from a fraction of the relevant knowledge. In this talk, I will present an approach to engineer such features automatically, by mining natural language documents such as research papers, industry reports and hacker forums. We utilize techniques inspired by IBM’s Watson question answering system, and we address challenges and opportunities specific to the security domain. As a proof of concept, we train a classifier with automatically engineered features for detecting Android malware, and we achieve a performance comparable to that of a state-of-the-art malware detector, which uses manually engineered features. In addition, our techniques can suggest informative features that are absent from the manually engineered set, and they can link the features generated to human-understandable concepts that describe malware behaviors. Finally, I will discuss the remaining challenges for automatically extracting semantic security insights from natural language and the opportunities that this direction opens for understanding and predicting adversary behaviors.
