Malware sites to block 14/1/13

A couple of interesting posts over at Malware Must Die!  showed some significant nastiness on a few IP ranges you might want to block. The IPs mentioned are:

91.243.115.140 (Aztek Ltd, Russia)
46.166.169.238 (Santrex, Netherlands)
62.76.184.93 (IT House / Clodo-Cloud, Russia)

I'll list the sites on these domains at the end of the post for readability. But in these cases, blocking just the single IPs is not enough as they reside in pretty evil netblocks which should be blocked altogether.

91.243.115.0/24 (Aztek Ltd) is part of this large collection of malware hosts. Perhaps not all sites in the network are malicious, but certainly a lot of them are. I would err on the side of caution and block access to all sites in this /24, legitimate or not.

46.166.169.0/24 (Santrex) is another horrible network. According to Google, out of 4604 tested sites in this block, at least 3201 (70%) are involved in malware distribution. There may be legitimate sites in this /24, but since customer service is allegedly atrocious then it's hard to see why they would stick around. Again, blocking this /24 is probably prudent.

62.76.184.0/21 (IT House / Clodo-Cloud) is quite a large range to block, but I have seen many malicious sites in this range, and like Aztek it is part of this large network of malware hosts and it has a poor reputation. This is only a part of this netblock, if you want to go further you could consider blocking 62.76.160.0/19.

These following domains are all connected to these two attacks:
