Malware sites to block 11/7/13

I noticed 188.138.89.106 (Intergenia AG, Germany) was the originating IP being used in this spam run using a hijacked 1&1 account, and VirusTotal thinks that the server is pretty darned evil. A quick poke at this box shows that has a number of multihomed malicious and C&C domains.

Looking at some of these servers, I'm suspicious that they may have been compromised using a Plesk vulnerability.
