New findings by researchers at the Georgia Institute of Technology and Google on a malicious DNS-related attack have stirred some debate over whether open recursive DNS servers are inherently insecure. DNS servers basically translate domain names, like darkreading.com, into IP addresses so that computers can find one another. Recursive DNS servers respond to DNS lookup requests from any machine on the Internet.
The researchers found an increase in corrupted DNS servers that send clients to malicious sites, and concluded that the large number of open recursive DNS servers on the Net could ultimately be compromised and used as part of a malicious DNS infrastructure that routes users to phishing sites and other bad places.
