How To decrypt apps on Jailbroken device based on frida

On Your phone you need frida :

https://www.frida.re/docs/ios/

Windows / Mac / Linux

On your desktop you need npm

- NPM : https://nodejs.org/

- zip command (optional). We'll generate an ipa archive when this command is avaliable

Windows Compatibility

Before [email protected] it was unable to connect device via USB (ref: https://frida.re/news/2019/05/15/frida-12-5-released/). Please use up-to-date frida to overcome this;
Filesystem of iOS differs from Windows. If you are running bagbak on Windows, some of the file attributes (e.g., executable bit) will be lost, thus the repacked ipa may not be able to reinstall on your phone. But it does not matter if you only indend to do static analysis.

Open Your terminal and past : npm install -g bagbak

once you are done connect you jailbroken device to your Desktop

Create a folder like on Desktop called "apps"

now open your folder , and type cmd in the folder path

now your terminal is directly in your "apps" path

Now you can execute bagbak directly from your terminal

Usage

bagbak [bundle id or name]

 Options:
    -l, --list             list apps
   -H, --host <host>      hostname
             -u, --uuid <uuid>      uuid of USB device
           -o, --output <output>  output directory
            -f, --override         override existing
                -e, --executable-only  dump executables only
                   -z, --zip              create zip archive (ipa)
                   -h, --help             output usage information
