摘要: The problem of malware classification has gained the attention cyber security community due to following facts: (1) thousands new are generated every day (2) global losses caused by in billions dollars year. In this paper a novel scheme is proposed that based on Hidden Markov Models (HMMs) and discriminative classifiers. Sequences system calls during execution represented as observation sequences train HMMs. Individual samples then evaluated against these models generate similarity vectors, which used predict class label for an unknown sample training classifier. Our combination HMMs, dynamic program features classifier shown promising results experiments performed using call logs real malware.
