This post is part of a series about Offensive BPF. Click the “ebpf” tag to see all related posts.
It has been a while that we posted something in the “Offensive BPF” series. But recently there have been a couple of new cool ebpf based tools, such as TripleCross, boopkit and pamspy.
So, I thought it be quite fitting to do another post in the Offensive BPF series to keep raising awareness.
Let’s sniff PAM again - pamsnoop.btA few weeks back we discussed a backdoor PAM module to grab authtok tokens (e.g. SSH passwords) when someone logs on to a machine. In this post we will build an eBPF program using bpftrace to do the same. Kudos for the idea using eBPF go to citronneur.
