30 Malicious IP list and Block lists providers 2015
From the post:
Stop and use this great Malicious IP lists to block unwanted traffic to your network and company. These lists are daily updated by the best security companies which keep track of malicious domains, IP addresses and more.
The malicious IP list providers which have been listed provide FREE information about malicious IP’s and they also provide block lists which you can use in your firewall or security configuration to block unwanted traffic. It is important to keep in mind that IP addresses are often dynamic and that they can be used in the future for legitimate traffic, so I do urge you to be aware when you use a block list.

Rather oddly, the post gives an alphabetical listing of the malicious IP and block list providers, 2015, but then lists the URLs for those providers in the same order, in a separate file.
Certainly these lists will be useful for security purposes but it occurs to me they would also be useful for the collection and study of malware. Rather than casting about for malware, you could use these lists as treasure maps, perhaps even tracking the spread of new malware across these sites.
Is there a pubic collection of viruses, etc. as found in the wild? Think of the marketing opportunities if software virus collecting and analysis became a major hobby.
