Test DNS Servers Against Known Security Flaw

Posted on 7.14.2008 today announced DNS Vulnerability Check, a tool that verifies whether DNS servers are vulnerable to the critical DNS flaw. This flaw allows attackers to poison a DNS server cache by injecting it with forged data -- making it such a significant flaw that the government's cyber security arm, and 80 vendors including Nominum, Microsoft and Cisco, coordinated together to issue a patch.   The tool is free and will be available tomorrow at
"This particular DNS attack is without a doubt the most dangerous discovered in the DNS to date," said Paul Mockapetris, Inventor of DNS. "It is imperative that IT managers for organizations Worldwide update their DNS software right away. The update on caching servers' perimeters will ensure optimal performance, and the new tool provided by is just what companies need to stay on top of their DNS, and prevent them from becoming victims of damaging exploits such as the one discovered by Kaminsky."
