To get a one-glance comprehensive view of the behavior of this Trojan, refer to the Threat Diagram shown below.

This malware is a Trojanized version of the Android application, Dog Wars, and is being distributed in third-party application stores.

The real version of the said application previously gained attention after PETA (People for the Ethical Treatment of Animals) conducted campaigns asking the creators of the application to discontinue their development.

Once installed, ANDROIDOS_DOOGRAW.A sends a text message with the word "text" to the number 73822. The said message subscribes the user to an alert service being offered by PETA. This results in unauthorized service charges to the user.

ANDROIDOS_DOOGRAW.A also sends a text message to all users in the user's contact list. The message depicts the user as someone who takes enjoyment in hurting small animals. This routine could damage the user's reputation among his contacts.

This Trojan may be manually installed by a user.
