Welcome To MachInjectSample
This project has been merged into the mach_inject repo.
MachInjectSample demonstrate the use of mach inject with the new SMJobBless API. By creating a privileged helper tool with the SMJobBless API, we can avoid asking an admin password each time we need to inject code into a process.
Description of contents
- MachInjectSample: The app.
- Installer: a helper tool (launch-on-demand) for installing mach_inject_bundle.framework (needed by the injector). This avoid the need to create a pkg installer, as the injector need to know the path to mach_inject_bundle at compile time.
- Injector: a helper tool (launch-on-demand daemon) for injecting code in a process.
- Payload: a bundle running inside the process. For demonstration purpose, it just write a message in /var/log/system.log upon loading.
Before testing, you need to code-sign the app, injector and installer with the same certificate.
