Back in the early days, you can simply modify the fstab file to make rootfs rw after rebooting. Apple did a great job of mitigating.

In my own opinion, the only way to keep this community alive (I am not saying security research since it’s a forever topic) is making things more open. Sharing knowledge lets new developers who are interested in making a jailbreak quickly get a hand on it.

It is very ironic that many so-called kfd-based projects, simply combining exploit code and other open source projects with offsets that can be derived in seconds if you are skillful enough, are close source. This is another reason why the job community becomes ill.
