According to Microsoft, Morto is a worm that spreads by trying to compromise (lame) administrator passwords for Remote Desktop connections on a network. They also note it can perform Denial of Service attacks against attacker-specified targets.
I can add that it runs what it looks like a quick DoS test against one Google IP. In addition, it creates a lot of traffic: RDP scans, downloads, receiving commands, and interesting DNS queries for command and control servers.
Judging by the domain owners of CC servers (China) and their location (Hong Kong), I would say it is likely it be cybercrimeware originating in erm,...Asia. I don't know how difficult it is for a foreigner to register domains with Jiangsu Bangning Science & technology Co. Ltd.in China. One of the domains existed for a few years and changed several Chinese registrars and hosting companies. Like in Russia, DDoS attack crimes are very common in China (I don't have stats for other Asian countries but I am guessing common there too :)
