  By default, communications will happen over USB, unless the --network
  option is provided.

Find Application

Use Frida to check for installed applications on the phone:

Show running applications:

1
frida-ps -Ua
  • -U for USB mode
  • -a for applications only

Show all installed applications:

1
frida-ps -Uai
  • -i for install applications

You should see something like this:

root@kali:~# frida-ps -Ua

 PID  Name        Identifier               
----  ----------  -------------------------
2594  DuckDuckGo  com.duckduckgo.mobile.ios

Attach to Application

Once we know the name of our target application, we can attach to it with the following command:

1
objection -g NAME explore
  • Where NAME is DuckDuckGo or com.duckduckgo.mobile.ios in the above example.

A command can be executed as soon as Objection attaches to an application using:

1
objection -g com.duckduckgo.mobile.ios explore --startup-command "COMMAND"
  • COMMAND might be something like ios sslpinning disable on an iPhone.

A single command can be executed instead of exploring the application:

1
objection -g com.duckduckgo.mobile.ios run "COMMAND"
  • COMMAND might be something like ios cookies get on an iPhone.
