I had a 4.9 box compromised though the ssh install (I'm certain it
wasn't openssh, but the base install), and was running an irc server
itself.

I just yanked the box off the net, and scrubbed it flat, and
reinstalled. In my case, it wasn't worth the time to track who and
when and how; I needed to put the server back on the net.

Good luck on chasing them down.

Are you sure that effort is worth it to you?
