Makes use of the framework's Accessibility service

Queries the phone number (MSISDN for GSM devices)

Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps)

Loads dropped Dex/Jar

Queries the mobile country code (MCC)

Queries the unique device ID (IMEI, MEID, IMSI)

Declares broadcast receivers with permission to handle system events

Declares services with permission to bind to the system

Requests dangerous framework permissions

Acquires the wake lock

Makes use of the framework's foreground persistence service

Performs UI accessibility actions on behalf of the user

Reads information about phone network operator.

Requests accessing notifications (often used to intercept notifications before users become aware).

Requests modifying system settings.

Requests disabling of battery optimizations (often used to enable hiding in the background).

Uses Crypto APIs (Might try to encrypt user data)

Registers a broadcast receiver at runtime (usually for listening for system events)
