Virus description added:

SHA1: a5c0b22e972692b828ef3f82754ecf710eec974e

Android.BackDoor.40 is an executable UNIX file designed to run on Android mobile devices. It is incorporated into Android.Backdoor.260.origin as an additional module.

Unlike Android.BackDoor.42, to which Android.BackDoor.40 is similar in many ways, this Trojan does not get installed into a system folder, but resides locally in the folder of Android.Backdoor.260.origin. Moreover, it communicates with other malicious components through UNIX sockets by calling a Java code to get contact list data, monitor SMS messages, and track GPS coordinates of the infected device.
