Cybercrimes have increased against Android devices due to the increased usage of Instant Messaging, Global Positioning Systems (GPS) and Webcam Applications which are built into the Android device, 

resulting in invasion of the victim’s privacy. The existing studies demonstrate how to utilize the vulnerabilities of the Android device; however, none have proposed a comprehensive study highlighting the 

hacking tricks and their countermeasures. This study demonstrates how to discover and fully control the Android device using existing tools. Furthermore, it proposes a novel GPS Tracking Application.

 The purpose of this research is two fold:

 1. To demonstrate how to disclose the victim’s sensitive information after performing diverse hacking tricks; and .

2. To implement countermeasures for each Android hacking trick. 

3.Application developers to mitigate existing vulnerabilities, thereby enhancing security levels.

4.In September 2015, the popularity of the 

WhatsApp messaging application reached 900 million users worldwide.
