Recently, AI techniques have shown great potential to strengthen the capability of traditional software analysis approaches. This talk will show how deep learning facilitates software testing and how NLP helps to analyze voice apps (skills). Firstly, we talk about fuzzing. Recently, directed grey-box fuzzing (DGF) becomes popular in the field of software testing. We propose a deep-learning-based approach to predict the reachability of inputs (i.e., miss the target or not) before executing the target program, helping DGF filtering out the unreachable ones to boost the performance of fuzzing. Evaluations on 45 real vulnerabilities show that FuzzGuard boosts the fuzzing efficiency of the vanilla AFLGo up to 17.1×. Secondly, we talk about skills. Smart speakers have been popularly used worldwide, mainly due to the convenience brought from the virtual personal assistant (VPA) which offers interactive actions through the convenient voice commands from users. However, to the best of our knowledge, there is no prior research that systematically explores the interaction behaviors of skills, mainly due to the challenges in handling skills' inputs/outputs in natural languages. We propose a systematic study on behaviors of skills and finds thousands of suspicious skills.
