I have seen broken or failed attempts that resemble this. Not identical or
using the same IP's, but using a trojan to infect, then quickly get the
backdoors in place, but they don't work or may not work. I don't know if it
is part of a rootkit, or other malware, it simply reminded me of this event
so I thought I'd mention it.

What leads me to ask to check for rootkits? Well there is a variety of
software available that can do this. Why not? Maybe something (else)
suspicious will pop up.

I wasn't trying to be conclusive, just making a suggestion. Sorry if anyone
misunderstood as a result.

I'd agree. Further analysis is warranted.

But if it was a simple trojan a detection and clean would solve the problem.
Since there appears to be some unknown variables still suspect, I'd look at
it like a rootkit, if it turns into a simple spam or ddos tool then so be
it. If it's a bot, then that is like many, many different malwares...what
the bot does is certainly more important.
