Malicious Activity Summary
Octo payload
Octo
Removes its main activity from the application launcher
Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps)
Makes use of the framework's Accessibility service
Loads dropped Dex/Jar
Queries the phone number (MSISDN for GSM devices)
Declares services with permission to bind to the system
Requests disabling of battery optimizations (often used to enable hiding in the background).
Queries the mobile country code (MCC)
Requests dangerous framework permissions
Acquires the wake lock
Queries the unique device ID (IMEI, MEID, IMSI)
Declares broadcast receivers with permission to handle system events
Reads information about phone network operator.
Performs UI accessibility actions on behalf of the user
Makes use of the framework's foreground persistence service
Requests accessing notifications (often used to intercept notifications before users become aware).
Registers a broadcast receiver at runtime (usually for listening for system events)
Uses Crypto APIs (Might try to encrypt user data)
