1. estimated 4.5 million infected machines

2. it infects the Master Boot Record

3. it uses the Kad Network (http://en.wikipedia.org/wiki/Kad_network) to issue commands to the clients (No idea how, the article did not explain this)

4. it disables competing malicious software

5. it acts as a malicious software manager; they install software for their "customers" to temporarily use
