# ios-inject-custom

Example showing how to use Frida for standalone injection of a custom

payload. The payload is a .dylib that uses Gum, Frida's low-level

instrumentation library, to hook `open()` and print the arguments on

`stderr` every time it's called. The payload could be any shared library

as long as it exports a function with the name that you specify when

calling `inject_library_file_sync()`. In our example we named it

`example_agent_main`. This function will also be passed a string of

data, which you can use for application-specific purposes.

Note that only the build system is iOS-specific, so this example is

easily portable to all other OSes supported by Frida.

# Prerequisites

- Xcode

- Jailbroken iOS device

# Running

```sh

$ make

```

This will build the injector, the payload, and an example program you

can inject the payload into to easily observe the results.

Next copy the `bin/` directory onto your iOS device someplace outside the

sandbox, e.g. `/usr/local/ios-inject-example/`. (Technically only the `inject`

binary needs to be located outside the sandbox.)

In one terminal SSH to your device and launch the `victim` binary:

```sh

$ ./victim

Victim running with PID 1303

```

Then in another terminal change directory to where the `inject` binary

is and run it:

```sh

$ ./inject 1303

$

```

You should now see a message printed by the `victim` process every time

`open()` is called.
