Abstract

This talk will introduce a promising avenue for improving the effectiveness of behavioral-based malware detectors is to combine fast (not highly accurate) machine learning methods with high-accuracy but time-consuming deep learning models. The main idea is to place software that receives borderline classifications from machine learning methods in an uncertain environment, and leverage deep learning models to do further analysis. The uncertainties will disproportionately affect poorly-written malware compared to well-written and resilient benign software, with the increasing demand for defensive programming. This talk will also discuss a statistical analysis of application sensitivity to OS uncertainty, which can help developers discover challenging bugs and identify the scenarios that most need validation. The results provided insights for software developers in building more resilient software.
