In a previous post, I mentioned how botnets have grown in size and sophistication that we should gear up for some real attacks coming from them. I think we will begin to see more attacks like the one that happened a couple of weeks ago in China. A DDOS attack against a popular domain registrer in China. The DDOS attack was specifically against the domain name servers (DNS). The DNS servers resolve the friendly name like www.mydomain.com to the numbered IP address that is assigned to the web server. When a system like this comes under attack, it makes it so other cannot get to the system, and therefore cannot resolve the name. Effectively this blocks their access to the site…even though the site itself wasn’t attacked. As time goes on and with the continual growth of botnets, we will see more attacks like this.
