In this second part, we turn to detection engineering. We begin by showing why static detection is often unreliable against Linux rootkits, even when binaries are only trivially modified, and then move on to behavioral and runtime signals that defenders can use instead. From shared object abuse and LKM loading to eBPF, io_uring, persistence, and…
