With the rising popularity of Android mobile devices, the amount of malicious applications targeting the Android platform has been increasing tremendously. To mitigate the risk of malicious apps, there is a need for an automated system to detect these applications. Current detection techniques rely on the signatures of well-documented malware, and hence may not be able to detect new malware samples. Instead of generating signatures for malware samples themselves, in this work, we propose to develop a lightweight system that can generate signatures of malware writers by leveraging the string components present in their Android binaries. Using these author signatures, we can effectively detect a wide range of existing, as well as any new, malware samples generated by particular authors. The proposed system achieved 98%, 96%, and 71% accuracy over datasets of 1559 benign, 262 malicious, and 96 …
