The second announcement is significant to all OpenDNS users as well as the entire Internet community. Today we’ve rolled out a way for you to see if Conficker is living on your network. The Conficker worm, also called Downadup and Kido, is massive. Some estimates of how many PCs are compromised are as high as 10 million. What’s interesting about this particular virus is that it uses the Domain Name System in a unique way: Conficker contains an algorithm that checks 250 new domains per day for instructions on what it should do. This puts us in a unique position to keep you safe since we’re in the unique position of providing insight and intelligence into your DNS service. We’ve teamed with Kaspersky Lab to identify those 250 daily domains, and stop resolving them. This means if you’re using OpenDNS, Conficker will do your network no damage. Yet another reason for your friends and colleagues to make the switch. While OpenDNS represents just a tiny drop in the sea of the Internet users today, we think this is a smart move forward.

To find out if Conficker has penetrated your network, simply log in to your account and select Stats on the left sidebar. From there choose Blocked Domains and filter “only domains blocked as malware.” This will generate a list of malware sites your network has attempted to connect with.

This is just the beginning, folks. We’ve got a year’s worth of new features we’re cranking hard on to make your network better performing and more secure. Stay tuned…
