Injects a dynamic library into an already running process

Usage

   usage: cynject <pid> <dylib> [args...]

Example

Description

We want to get the bundle identifier for a certain process.

Creating a dylib

First we create a dylib. We have two different approaches to this. First is to use Iheos and create a tweak.

%ctor {
	HBLogDebug(@"Bundle Identifier: %@", [%c(NSBundle) mainBundle].bundleIdentifier);
}

After installation, the dylib will be in /Library/MobileSubstrate/DynamicLibraries

We could also use clang with this install script and create the dylib manually.

Injecting

Once we have the dylib

cynject 443 absolute_path/to/your_dylib_path.dylib

Profit

The bundle identifier should appear in the syslog
