The Trojan injects into the module and capable of performing various malicious activities such as stealing confidential information without user’s intervention.
Security researchers from Drweb Discovered the trojan dubbed Android.Triada.231 in the middle of 2017. Now they identified another 40 devices infected with the trojan.
Researchers said “The key feature of Android.Triada.231 is that cybercriminals inject this Trojan into the libandroid_runtime.so system library. They do not distribute the Trojan as a separate program. As a result, the malicious application penetrates the device firmware during manufacture. Users receive their devices already infected from the box.”
