Malicious Activity Summary

octo banker collection credential_access discovery evasion impact infostealer persistence rat stealth trojan

Octo

Octo family

Octo payload

Removes its main activity from the application launcher

Makes use of the framework's Accessibility service

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

Queries the phone number (MSISDN for GSM devices)

Makes use of the framework's foreground persistence service

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

Declares broadcast receivers with permission to handle system events

Requests dangerous framework permissions

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

Requests modifying system settings.

Performs UI accessibility actions on behalf of the user

Declares services with permission to bind to the system

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

Queries the mobile country code (MCC)

Reads information about phone network operator.

Acquires the wake lock

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

Uses Crypto APIs (Might try to encrypt user data)
