A post about the HTTP(S) Sliver C2 protocol. I'll show how to use beacons compiled with HTTP C2 endpoints, with a focus on illustrating the traffic these beacons generate. There is also some info on how to modify the traffic such that it looks less like the default. Before diving into the subject matter, there are also instructions for adding a web proxy to the lab setup that is built up iteratively in this series of blog posts.
