bad-bpf VS ebpfkit-monitor

Not going to find too many guides for BPF development. Best way to learn is by looking at existing code samples, like this repo

This is a good write-up and I like the diagrams. What appears to still be missing in an "off switch". AFAIK there are still no kernel boot time commands to disable eBPF entirely. I have to recompile the kernel to disable it.

eBPF has the potential for file-less malware to run hidden from detection and I foresee the ability to tickle ring -3 (and -4?) CPU within CPU functions while bypassing local firewalls.

Here is some example code of what people already know how to do today and this list will grow as people discover more capabilities. [1][2][3][4][5] These do require some privileges to insert but will remain running and hidden until reboot.

For anyone interested, there are a few more projects with similar capabilities to look at:

- Bad-bpf: https://github.com/pathtofile/bad-bpf

- Offensive BPF: https://embracethered.com/blog/posts/2021/offensive-bpf/

- Ebpf, I thought we were friends: https://m.youtube.com/watch?v=5zixNDolLrg
