What it detects
This rule detects creation of a binder.so library inside the Android system framework arm directory which the Triada trojan replaces to hook Zygote and inject into every app process. This system-level modification gives the malware persistent control over the device including clipboard wallet clipping and premium SMS abuse. A write to the framework native library path is highly abnormal on a clean device.
