This virus is of the trojan family, which when infected to the Android smartphone, can “completely compromise” it and allows the attacker to control the Android smartphone remotely.
A malicious toolkit called Dendroid is being used to create this trojanised application and the toolkit is used to control this malware as well. This trojanised malware infects the Android OS-based smartphones.This malware is created by modifying the permissions that are required by any clean(virus free) Android Package File(APK) with Dendroid RAT(Remote Access Trojan) functionality which as a result, allows detailed and easy management of the attacked devices.
Once this virus is activated, it could change the command and can control the server of the infected Android phone.It also performs many dangerous activities on the infected device.The results of this “attack toolkit” are:
- delete the call logs
