GRUBKit: Skeleton project for your own GRUB-based bootkit

Grubkit is a demonstration of a very simple trick to deploy your own bootkit on a system that boots with GRUB. The trick is simply to use your own code as the init parameter to the kernel, fork, start systemd as normal and you’re done! PSTree did not detect my bootkit when I did this. Seems like a good and simple method.[…]
