bad-bpf

This is a good write-up and I like the diagrams. What appears to still be notably missing from eBPF is an "off switch". AFAIK there are still no kernel boot time commands [0] to disable eBPF entirely. I have to recompile the kernel to disable it and it is known that most people will not do this. 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][6] These do require some privileges to insert but will remain running and hidden until reboot. Privilege escalation today is easier than ever with the growing misuse and poor configurations of sudo as well as the g

eBPF feature request for the eBFP foundation. The ability to completely disable eBPF without having to recompile the kernel, ideally in a kernel boot option. e.g. ebpf=0 Why? eBPF can bypass most facets of security controls and exposes potential and future file-less/disk-less vulnerabilities from trusted actors.
