What is Dynamic Analysis

As mobile applications are being developed at a faster pace, the security aspect of user information is being neglected. A compromised smartphone can inflict severe damage to both users and the cellular service provider. Malware on a smartphone can make the phone partially or fully unusable, cause unwanted billing, steal private information, or infect every name in a user's phonebook. A solid understanding of the characteristics of malware is the beginning step to prevent much of the unwanted consequences. This chapter is intended to provide an overview of security threats posed by Android malware. In particular, the authors focus on the characteristics commonly found in malware applications and understand the code level features that allow us to detect the malicious signatures. The authors also discuss some common defense techniques to mitigate the impact of malware applications.
