Control servers may also hop from dns domain to dns domain with domain generation algorithms being used to create new dns names for controller servers.

After describing passive botnet detection techniques by inspecting packet and flow records analysis in this blog entry we will describe how to use passive dns domain name system analysis techniques to detect botnets in a network. Researchers at texas a m university say they have a new method for finding domain fluxing botnets which evade detection by constantly alternating domain names.
