Andro-Dumpsys: Anti-Malware System Based on the Similarity of Malware Creator and Malware Centric Information 

1.  Introduction 

Andro-Dumpsys is an anti-malware system based on similarity matching of malware-centric and malware creator-centric information. Our system runs a target application on an emulator, extracts odex bytecode—which basically collects parts of an application that are optimized before booting through volatile memory acquisition (dynamic analysis) in order to address the obfuscation, packing, dynamic loading techniques. Then, our system parses meaningful and relevant code patterns from the odex file and creates a profile of each application. In particular, for grasping the intent of malware creator, we leverage footprints, including the serial number of a certificate, operation codes (opcodes) in odex files, and meta-data in AndroidManifest.xml as feature vectors for malware characterization. By comparing the profiles, our system can detect and classify malware samples into related families.
