Malware sites to block 8/11/2013 (Nuclear EK)

The IPs and domains listed below are currently in use to distribute the Nuclear exploit kit (example). I strongly recommend blocking them or the 142.4.194.0/30 range in which these reside. Many (but not all) of them are already flagged as being malicious by SURBL and Google.

The domains are being used with subdomains, so they don't resolve directly. I have identified 3768 domains in this OVH
