This is the best tl;dr I could make, original reduced by 87%. (I'm a bot)

Eset researchers discovered Mumblehard after being contacted by a system administrator who sought assistance for a server that was added to public security blacklists for sending spam.

The researchers identified and analyzed a process that was causing the server to connect to different SMTP servers and send spam.

The almost 9,000 IP addresses Eset observed can't be directly correlated to the number of machines that were infected by Mumblehard, since in some cases more than one server may share an address and in other cases a single server may give up an old address and take up a new one.
