Malicious Activity Summary

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

Octo payload

Octo

Removes its main activity from the application launcher

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

Performs UI accessibility actions on behalf of the user

Declares broadcast receivers with permission to handle system events

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

Declares services with permission to bind to the system

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

Acquires the wake lock

Requests modifying system settings.

Makes use of the framework's foreground persistence service

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

Reads information about phone network operator.

Requests dangerous framework permissions

Queries the mobile country code (MCC)

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

Uses Crypto APIs (Might try to encrypt user data)
