Zhuang Zhang, Bo Shi, Hangfeng Dong, from Tencent Yunding Lab(Tweet@YDLab9) Since the malware come out, there is a fight between malware and AV. So more and more methods based on machine learning apply to detect malware. We will share how to detect polymorphic malware based on CNN，then we will introduce a method use generative adversarial network to generate adversarial malware examples to bypass machine learning based detection models.
