BPF is a kernel technology that can be misused for malicious purposes, like "Linux Kernel Module Injection". This
rule should be considered an auditing rule to notify you of any unprofiled BPF tools running in your environment.
However, it requires customization after profiling your environment. BPF-powered agents make bpf syscalls all the
time, so this rule only sends logs for BPF_PROG_LOAD calls (bpf cmd=BPF_PROG_LOAD) in the enter event. If you also want to log
time, so this rule only sends logs for BPF_PROG_LOAD calls (bpf cmd=5) in the enter event. If you also want to log
whether the syscall failed or succeeded, remove the direction filter and add the evt.arg.res_or_fd output field.
condition: >
evt.type=bpf and evt.dir=>
and evt.arg.cmd=BPF_PROG_LOAD
and (evt.arg.cmd=5 or evt.arg.cmd=BPF_PROG_LOAD)
and not bpf_profiled_procs
