Backdoor.AndroidOS.Triada gives root privileges to itself and to other Trojans that it downloads, in order to make changes to system files. The malware sends information about the infected device to a remote command-and-control server and downloads a configuration file, which contains the ID of the infected computer and configuration settings.
The main function of the Trojan is to redirect financial SMS transactions when the user is making online payments for purchasing additional content in legitimate applications. Instead of being sent to the developer of the additional content, the money is sent to the criminals.
Some versions of the Trojan modify the Zygote process. This process is one of the core processes on Android devices. It contains system libraries and frameworks that are used by every application on the device, and is the basis for all other applications.
The main part of Backdoor.AndroidOS.Triada resides only in the device RAM, making the Trojan very difficult to detect. In addition, all Trojan processes that are separately launched are hidden from the user and other apps.
