Hm, as of this frauder binary, I have my strong doubts... looked at it, and 
it's a plain brute forcer / banner grabber which is statically linked against
SSH-2.0-libssh-0.1. No magic visible, at least not in the given timeframe, and 
my gut feeling is that that's it.

I assume in the aforementioned takeovers other factors were involved.
