Active Malware Analysis focuses on learning the behaviors and the intentions of a malicious piece of software by interacting with it in a safe environment. The process can be formalized as a stochastic game involving two agents, a malware sample and an analyzer, that interact with opposite objectives: the malware sample tries to hide its behavior, while the analyzer aims at gaining as much information on the malware sample as possible. Our goal is to design a software agent that interacts with malware and extracts information on the behavior, learning a policy. We can then analyze different malware policies by using standard clustering approaches. In more detail, we propose a novel method to build malware models that can be used as an input to the stochastic game formulation. We empirically evaluate our method on real malware for the Android systems, showing that our approach can group malware belonging to the same families and identify the presence of possible sub-groups within such families.

Abstract

Active Malware Analysis focuses on learning the behaviors and the intentions of a malicious piece of software by interacting with it in a safe environment. The process can be formalized as a stochastic game involving two agents, a malware sample and an analyzer, that interact with opposite objectives: the malware sample tries to hide its behavior, while the analyzer aims at gaining as much information on the malware sample as possible. Our goal is to design a software agent that interacts with malware and extracts information on the behavior, learning a policy. We can then analyze different malware policies by using standard clustering approaches. In more detail, we propose a novel method to build malware models that can be used as an input to the stochastic game formulation. We empirically evaluate our method on real malware for the Android systems, showing that our approach can group malware belonging to the same families and identify the presence of possible sub-groups within such families.
