Trojan.AndroidOS.Triada obtains root privileges, which enable it to change system files, and provides such privileges to other Trojans that are downloaded by it. 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.
Most of Trojan.AndroidOS.Triada resides exclusively in the device RAM, making the Trojan extremely difficult to detect. In addition, all Trojan processes that are separately launched are hidden from the user and other apps.
