Local privilege escalation (LPE) is the step that turns a foothold into full control of a host. An attacker who lands as an unprivileged user rarely stops there. They want root, and Linux keeps offering new ways to get it.In this edition of our "Linux Detection Engineering" series, we’ll cover:The default flow that a Linux LPE produces on the host and the general rules that detect it.The recurring LPE patterns behind the most recent LPEs and how each works, along with how each looks through the…

Introduction In part one, we examined how Linux rootkits work: their evolution, taxonomy, and techniques for manipulating user space and kernel space. 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…
