Malicious Activity Summary

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

Octo

Octo payload

Removes its main activity from the application launcher

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)

Makes use of the framework's Accessibility service

Loads dropped Dex/Jar

Declares broadcast receivers with permission to handle system events

Reads information about phone network operator.

Requests dangerous framework permissions

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

Makes use of the framework's foreground persistence service

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

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

Performs UI accessibility actions on behalf of the user

Acquires the wake lock

Queries the mobile country code (MCC)

Declares services with permission to bind to the system

Requests modifying system settings.

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

Uses Crypto APIs (Might try to encrypt user data)
