Androrat 

AndroRAT is an open-source client/server application developed in Java/Swing for Servers and Java for Clients. This operating system is the Remote Access Tool (RAT) for Android which is used to attack a victim or an attacker.

AndroRAT can be used as a client-side Android application on the target phone and as a server-side application on a hacker or attacker computer. In other words, you can take full control of a single Android target phone or device remotely from your computer using this client/server application.
